Habs coach Therrien on facing Pittsburgh: 'It's going to be special'
Mar 1, 2013, 7:50 PM EDT
Montreal bench boss Michel Therrien isn't holding back in expressing anticipation over playing his former team.
The Canadiens will host the Penguins — the club Therrien took to the Stanley Cup finals in 2008 — on Saturday night, the first time he's faced Pittsburgh since being sacked in 2009.
"It's going to be special, I'm not going to hide it," Therrien told the Canadian Press. "But I've got some great memories of my time in Pittsburgh.
"There are some players I know well. I have a lot of respect for them. But to play against your old team as a player or a coach is special."
The 2008-09 Penguins were a heavy Cup favorite after losing to Detroit in the finals the year prior, yet never were able to get things going.
After posting a 27-25-5 record through 57 games, the team made the decision to replace Therrien with Dan Bylsma…and the Pens went on to win their first Stanley Cup in 17 years.
A number of the Penguins that played under Therrien are still with the team: Sidney Crosby, Evgeni Malkin, Kris Letang, Pascal Dupuis, Tyler Kennedy, Matt Cooke, Brooks Orpik, Chris Kunitz and Mark Eaton, to name a few.
Therrien says he remembers the team fondly and is looking forward to facing them at the Bell Centre.
"It was a challenge. No one expected us to be in a Stanley Cup final that quickly," he explained. "We're in first place now and they're in second, but playing against that team is a challenge even if Malkin (concussion) is out.
"There's only seven or eight guys left on that roster since I left, but the identity is always the same."

Iam truly not saying this to get a reaction ! Crosby should watch himself in this game this HABs team is sneaky dirty ,especially at home !
Of course you are you live for the comments dude! If you ever Said anything intelligent I would agree with you, but you don't so I can't.

Ok but I hope I don't have to say I told you so genius ! Trust me,,, I want him in the lineup for Thursday's night game their genius,those tickets down at the Wells Fargo ain't cheap like your old lady their genius !
- thebadguyswon - Mar 1, 2013 at 8:32 PM
What the Habs are is very deep on defense. And the addition of Brandon Prust added a much needed dose of badass.
- govtminion - Mar 1, 2013 at 9:53 PM
Tacking on Ryder means they've got a pretty solid looking power play unit too. Watch the penalties, Pittsburgh!
- killerpgh - Mar 1, 2013 at 10:12 PM
If he thought the Penguins defense was "soff" back when he was the coach I would love to hear want he thought about them the past 2 or 3 games.
- steelers88 - Mar 1, 2013 at 11:24 PM
The Penguins will be white washed tomorrow night. I'm predicting a 5-0 Habs win. I'm sorry Penguins fans but the Penguins won't win the Cup this year. In fact I think they might be bounced in the first round again. The reason why is because they have a terrible work ethic and don't seem to care. They always seem to get outworked which is unusual for a Penguins team. Something has to be done I think they should fire Dan Byslma.
- sportsfreak13 - Mar 2, 2013 at 1:38 AM
Stick to football man. We're on a 2 game slide that has exposed some glaring weaknesses. It's not the end of the world. They have showed earlier on this season how they can play when their all on their game and paying attention to details. Why would you fire bylsma and risk a new coach changing the system mid season when your first in your division. This is just the ebs and flow of a hockey season. Don't overact. Did the LA kings look like a cup winning team during game 42 of last years regular season?
- blomfeld - Mar 2, 2013 at 12:34 AM
To hell with Saturday night pal. What's going to be "special" is if we LA Kings meet "you people" this June in the final. And if it comes to be, God willing, then that will mark 20 years since we met "you people" in the final last time … you remember, that little dust up where "you people" saw fit to carry the day by resorting to cunning and treachery calling out the "supposed" length of McSorley's stick in-order to gain an advantage. Well this time around "you people" won't be dealing with any of this Mister "Nice Guy" Gretzky stuff. Nor sir, "you people" will be dealing with the new "battle-proven" and supremely "victorious" LA Kings, who couldn't give a rat's ass about you or your precious "Les Habitants" history. So do win this weekend and please promise to make it to the "high ground" this June, where we'll be waiting for "you people" !
- steelers88 - Mar 2, 2013 at 9:08 AM
I just think they just aren't that good either they aren't deep enough in offense this year. I think their overrated I also think Penguins fans are living in the past with the 2008-2009 Cup team they defiantly aren't that team not even close to being that good.
- sportsfreak13 - Mar 2, 2013 at 10:44 AM
You do know that come game 62 of the regular season in 08-09 that cup team didnt even look close to being a playoff team let alone a cup contender. Things change in hockey realy fast and trust me when i say being deep enough on offense is not their problem at all. You dont need your third and fourth lines constantly putting pucks in the net. When healthy our top 2 lines are more dangerous then anyone else in the league(neal line 2, 2nd in the league in goals, crosby line 1 top in the league in assits). The problem is paying attention to the defensive breakdowns and limiting the amount of turnovers in the netural zone. When playoffs come around any one of the 16 teams can win the cup, its all about matchups and how well your playing at the time. Right now were #2 in the east so i wouldnt panic.
- csilojohnson - Mar 2, 2013 at 10:15 AM
A coaching change right now would be the dumbest thing the Pens could muster. Just short of trading Crosby and Malkin. Commands us one of the best coaches in the league. Every team goes through ups and downs. They will get back on track.
I'm just grateful that steelers88 is not the teams GM.
- steelers88 - Mar 2, 2013 at 10:42 AM
Well they need shakeup this team up somehow. Make a trade for a top 6 winger. I just love how people assume that the Penguins will make the playoffs. Steelers fans said the same thing earlier this year and looked what happened.
- steelers88 - Mar 2, 2013 at 11:00 AM
Even if the Penguins do make the playoffs. I don't think their consistent enough on defense to go deep in the playoffs. I don't think they can beat teams like the Flyers and the Devils.
- sportsfreak13 - Mar 2, 2013 at 11:14 AM
So how does a top 6 winger help us there?
- steelers88 - Mar 2, 2013 at 11:48 AM
Paul Martin will not play tonight.

Very delicious! I added ground turkey and used 2 zucchini and 2 yellow squash. I added 1 teaspoon of cumin and a little extra chili powder because of my additions. I also used frozen corn instead of the canned. I only used a couple spoonfuls of tomato paste. Thank you for the recipe!
This is a pretty good chili recipe. Tasty, vegetarian friendly, and full of vegetables! My only complaint is that it was a little spaghetti-sauce-tasting. Next time I make it, I'm going to add one of those "chili spice" packages and I think that will make it perfect!

This recipe was even better than we'd hoped. I omitted the yellow squash (didn't have any) and added a yellow pepper (along with the green pepper.) I also added a can of diced tomatoes because that's what I had in the pantry.
Since we aren't vegetarians, we added grated chedder cheese to the top. I also added LA Gold Hot sauce. But again, that was post-cooking. Serve this with some good corn bread and you'll score a home run! You won't be disappointed with this recipe.
Very wonderful! first off i have never made a chili before, (and i don't like beans). I bought a cornbread mix a couple of weeks ago and realized i needed to do something with it and thought well chili would work, and thus i stumbled onto this. I doubled most all the veggies since i am a veggie. it made enough left-overs for my boyfriend and I to enjoy for three days! (he even had chili dogs, since he is a meat eatter.) I used chedder cheese, chopped green onions, and even sour cream as toppings! this is a regular for me now!
This recipe is VERY GOOD the way it is! Especially if you are looking for a more Vegan diet, this will be on top of your list to prepare from here on out. To add any kind of meat to it would ruin it and take away the taste it was meant to have.
Fix it for what it is.. a VEGGIE Chili!
Great vegetarian dish. It wasn't as difficult to make as I had anticipated. I don't like yellow squash and omitted that and substituted a yellow pepper for the green pepper and also left out the jalapeno. Make sure you stir it occasionally as it's cooking, or else you'll end up scraping a lot of burnt chili from the bottom of the pot. Very filling; will definitely make it again!
I loved this recipe I did it in the slow-cooker and it came out great...My husband even loved it and he's not the one to like veggies at all
Nice vegetarian recipe! I used a can of diced tomatoes instead of the crushed tomatoes and tomato paste. Use any variety of vegetables you have on hand. Everybody agreed that they didn't miss the meat! Thanks, Jen!

Answer this2 AnswersPieter answered:Really anything outside of "town" isn't a tourist attraction. Namely the beaches. 'Sconset and Madaket beaches are two of the best (beach map here: http://1.usa.gov/ofZ1Yj ) If you're in town, there's a little sea kayak rental place (Washington Avenue, seanantucketkayak.com) that will get you away from the crowds and out to the barrier beaches very quickly.

Read Poems by
Boitumelo Mailula
For years we got love wrong,
Ran after lust thinking its love,
Our desire chained us to pain.
Expectations attracted deception,
Performance replaced true doctrines.
As we regarded humbleness boring,
The world lost its true inheritance.
In chase for material faith was lost.
Casual sex brought death of many.
Rights misused to replace discipline.
Respect faded with young lives.
In our chase for status,
Christianity lost true fellowship.
In our desire for independence,
Our children suffered violence.
Abortion answer to wrong choices,
As pornography tainted our screens,
Divorce escalated like air balloon.
Freedom defined by skin colour.
Are we really humans?
Or animals acting like humans,
Where is the humanity if we human…

If there's an insurance we should all invest in, that would be the health insurance. If you have this kind of insurance, you don't have to deal with too much medical bills and expensive drug prescriptions. That is because such checkups and tests are supported by this kind of insurance.
Studies even showed that those who have type of insurance are most likely the people who have annual general checkups. But depending on what kind of insurance you have, you and your family may be covered by even more benefits. To give you more facts, here are the most common types of insurance.
Free for service
This is yet the most common health plan there is, not to mention the most used as well. With a free for service insurance, you have the freedom to choose your doctors and physicians as well as the hospitals that will take care of you. Unlike other insurances, you also have an opportunity of referring yourself to any health care specialist you want.
On the downside, free for service also involves more out-of-the-pocket expenditures. There's also a deductible cost ranging from $200-$2,500 which should be paid before the insurance company begins paying and insuring you.
Managed care
This kind of health plan has existed since the 1930′s. Unlike the free for service wherein you can choose your preferred medical experts, this managed care insurance was more of an arrangement plan. Such agreement is between the insurer and the selected group of health care providers. A formal procedure is done to ensure that only the best doctors and physicians will be picked.
A PPO or preferred provider organization is another kind of insurance that's one step over the guided care border. This is linked to lower fees on arrangements with a group of doctors and other health care providers. A financial incentive is also given to the policy holders.
This plan also allows you to refer yourself to a doctor without asking for permission. However, that doctor should be a part of the arranged network or group. Nevertheless, you can still see outside doctors if you wish, but alongside that, you are entitled to pay the entire bill yourself.
Point of service
A point of service insurance or POS is quite similar to the PPO. The only catch though is that they're the ones who'll introduce you to the primary care physician. This insurance also allows you to choose out of network health care providers but will still let you obtain the same coverage. This is also known to cover more care services and it also offers health improvement services. Examples would be workshops on smoking and nutrition cessation.
Purchasing a health insurance is indeed important. However, you should keep in mind that gaining enough knowledge about it is more important than anything else. You should know your rights as well as the do's and don'ts to ensure that you're on the right track. There are many scams when it comes to health insurances and technically just any kind of insurance, thus it's still best to do a research first.

Indonesian banks maintained strong profit growth in July amid improving efficiency and a rise in income from fees and securities, despite a central bank move to tighten mortgage and automotive loans weighing on lending.
The country's 120 commercial banks posted collective profits of Rp 7.2 trillion ($752 million) in July, up 36 percent from the same period last year. The figures were derived by subtracting the January-June numbers from the seven-month data reported by Bank Indonesia on Friday.
In the first seven months, banks' combined profit rose 25 percent to Rp 52.9 trillion.
Commercial banks lowered their BOPO ratio — a measure of bank efficiency that compare their operating expense to operating income — to 74.9 percent in July from 87.4 percent in the same month in 2011.
A lower BOPO ratio is preferable as that would mean a bank makes more income for every rupiah it loans, and its operating expenses are smaller.
Banks posted a 39 percent increase in other operating income — such as fees and gains from securities assets — to Rp 12.4 trillion.
The lenders also reduced their operating costs slightly to Rp 20.8 trillion, down 0.1 percent from last year.
Bank Indonesia in mid-June introduced requirements that raised the down payments consumers were compelled to make for motorcycle, cars and homes in a move to prevent a bubble in those sectors and curb excessive consumer loan growth.
Consumers who finance their motorcycle purchases via bank loan must pay a minimum of 25 percent of the price tag as a down payment. For passenger cars, that requirement is 30 percent.
The new rule also imposes a 30 percent down payment on the purchase of homes that cover more than 70 square meters.
There were no such rules prior to the mid-June requirement, but banks usually ask for 10 to 20 percent of the purchase price as down payment.
Central bank data showed that commercial banks disbursed Rp 17.4 trillion in loans in July, down 25 percent from the same period last year. In line with the declines in loan growth, commercial banks' net interest income — the money it makes from loans minus deposits — dropped 30 percent to Rp 10.7 trillion in July.
Housing loans, however, more than doubled, to Rp 6.6 trillion from Rp 2.4 trillion. Overall, commercial banks' outstanding loans climbed 25 percent to Rp 2,488 trillion in July.

Routine work can dull alertness and a relaxed attitude can replace the caution that existed when the job was new and interesting. In many jobs the same route is traveled daily over the same roads or the same tasks are repeated with little conscious thought. Without some periodic reawakening to the ever-present hazards, lethargy deepens and the odds of an accident occurring can increase.
Workers may not always recognize the importance of safety training or think of it as unnecessary because they've "been doing it for years." But an important benefit of periodic safety training is the reminder that a danger can exist and the no one is immune to accidents. Therefore, it is important for workers to understand the purpose of the training session, why it will be useful to them, and what can result from not following safety rules and procedures.
The safety training should be organized so that the order in which the material is presented will match the steps that should be taken on the job. Make sure every worker understands the training material; not just that they were present or a test was given. Insist on questions from trainees after a session to tell you what did or didn't sink in. This will let you know what has to be reviewed again. If there's a general lack of understanding of hazards or safety rules and practices, schedule another safety meeting or plan a refresher course for a later date.
Employees should be able to immediately practice and apply new knowledge and skills. If workers don't understand safety training information well enough to use it on the job, the training has not been effective. There should be immediate feedback if workers are doing their job safely or not. Supervisors should watch employees do their jobs and question them, to identify what they do, or don't, know.
Most of these tips are relatively simple and inexpensive solutions, but the safety payoff can be enormous. Remember, training is only effective when workers understand, and use, what they've learned. It takes less than a second to lose the rest of your life.

The invention relates to a process for optimised control of a home and building automation system by way of software and sensors for monitoring persons, where the automation system, for energy saving and comfort improvement purposes, triggers actuators for installations or groups of installations as required. The invention also concerns an automation system for performance of the process and its application.
Home and building automation systems have already been proposed and implemented in many forms with a view to improving comfort. Government objectives and increasing environmental awareness contribute to the generally growing need to reduce energy consumption in order to protect global resources.
As early as the beginning of the 80's, the cooling and heating power of an air-conditioning system could be influenced in individual rooms in terms of comfort and energy in that an energy control system triggered by presence sensors was used, for example that described in U.S. Pat. No. 4,407,447. When the presence of a person in a room is according to this patent specification the temperature is adjusted from an uncontrolled room temperature to a prespecified nominal temperature by the supply of corresponding warm or cold air. When this person leaves the room, the air supply is cut off again and hence the energy consumption as a whole reduced. This system thus responds directly to direct requirements caused by the presence of at least one person, but has the disadvantage that in regard to the comfort system it has an inherent inertia. For example the thermal inertia of a room to be heated or cooled cannot be taken into account sufficiently or at all.
U.S. Pat. No. 4,567,557 describes a further developed building automation system referred to as intelligent. This has a centrally organised system with a multiplicity of input side sensors which send their information or control commands to a central processor, and actuators on the output side which receive control commands from the processor. The decisive factor in this system is firstly the centralistic approach, where all information must reach the central processor, and secondly the deterministic approach where all possible cases and combinations are programmed and stored as "behaviour patterns" for subsequent retrieval.
During the following years, systems have been developed and marketed known as "total home systems". These comprise lighting and object control via the installed power network, which can use the existing infrastructure without significant structural changes. The system consists of a central unit and various receiver units such as switches, dimmers and shutter control. As stated, the existing 230 V network line with sockets is used as the signal line. Thus complex control sequences for different procedural requirements can be stored and repeated within a building.
A deterministic approach is common to all known systems, in which preprogrammed sequences are triggered under time-control, at the request of sensors or by human intervention. Thus these systems, also known as mode programmes, can be used optimally only for specified situations and with time restrictions.
A change in user requirements requires reprogramming of the system, which is beyond the capacity of, or frightens a user, normally a layman. One example here is the change of use of a child's bedroom into a storage room, which in principle creates different conditions. Thus the known systems can only respond with difficulty, or unsatisfactorily, or not at all to spontaneous changes of environment and/or user behaviour. Thus for example a home automation system for households with professional family members is programmed to lower the temperature during the day. If one family member remains at home because of illness, the system responds incorrectly. Manual intervention is required. Resetting to normal mode is then often forgotten.
CH, A 683473 discloses a process for electronically delayed disconnection of the light with a passive infrared sensor as a movement sensor. Thus a specified output value or a stored learned value for time delay can be entered. This value is adapted automatically and continuously to the intensity of movement in the scope of the passive infrared sensor, and on any change of movement intensity a new time delay is continuously set. One specific problem, the optimum delay in disconnection of the lighting, is therefore no longer established exclusively deterministically, an intelligent disconnection delay for the light is matched to the user behaviour.
EP, A 0631219 describes a process for temperature control and adjustment in individual living and working rooms which are used only rarely but with a certain regularity. Constant living habits are taken into account, which should bring optimum comfort with maximum energy saving. A set value is modified to the regularities to be set in the room used as a function of presence times detected by the presence sensor for the following days according to a fuzzy algorithm. The at least partly stochastic behaviour of residents cannot be detected by the process.
The largely similar automatic temperature control and regulation system described in U.S. Pat. No. 5,088,645 is related to individual rooms and has no overall strategy. The algorithms do not contain any separation of deterministic and stochastic behaviour. Disruption factors are integrated by the system.
The present invention is based on the task of creating a process and a device of the type described initially which reduces to a minimum the process-controlled intelligence, the deterministic components of the home and building automation system, adapts automatically to the at least partly stochastic behaviour of persons in the building and hence allows both energy savings and comfort improvement.
In relation to the process, the task is solved according to the invention in that adaptive self-learning algorithms of the software, controlled by signals from presence and activity monitoring sensors, continuously store the systematic and stochastic behaviour of at least one person in the room concerned and over several rooms, adapt and trigger actuators in conjunction with modifiable deterministic algorithms, where the room-related optimisation algorithms are combined with external parameters into an algorithm to optimise the automation system as a whole and the individual room algorithms are adapted accordingly as feedback. Further and special design forms of the process are the subject of dependent claims.
The presence and activity monitoring with presence and activity-controlled control loops, the neuronal networks with their own computers which detect and evaluate the regular (systematic) and random (stochastic) behaviour, are of greatest importance.
The sensors arranged on the input side of the software, which is usually standard software or software adaptable with specialist knowledge which is stored in a CPU or processor, are for example movement sensors of all types. The most common are passive infrared sensors such as described for example in CH,A 683473 or the company brochure by High Technology Systems AG, CH-8306 Bruttisellen dated Dec. 3, rd 1994 (second issue January 1996). Further passive systems for example detect the noise or pressure waves generated by persons. Movement sensors can also be constructed on active principles, e.g. by emitting an ultrasound or microwave field or by the reception of a field influenced by a moving person. Changes in a static electrical or electromagnetic field can also be detected and the signals passed on for analysis by the software.
External parameters or information sources included in the room-related optimisation algorithms are for example the weather, the external temperature, safety modes or weather forecasts.
Sensors are not however restricted to movement sensors. For example smoke sensors, thermostats, light detectors and other sensors are suitable as input signal generators, to contribute to solution of the task according to the invention and/or to supplement this.
The electrical signals output by the computer, CPU or processor with the software, trigger allocated installations or installation groups via actuators. This is done directly or via intermediate components, for example a summing point and a PID regulator for a presence and activity-controlled control loop. The actuators can be single or multi-stage relays or other electromechanical devices known to the expert with normally open, normally closed or switching contacts. Installations or installation groups are for example lighting bodies, heating, valves for the flow of heating and cooling media, motors for venetian blinds and alarm systems.
According to the invention, the monitoring applies not only to the presence but also the activity of at least one person present in the detection area of a room monitoring system. The activity is stored and used by the software to trigger actuators.
Thus the initial models of user behaviour of at least one person which are stored on installation of the automatic system are adapted permanently to the changing user behaviour and the collected experience used as a prediction basis for the most probable following actions. By means of learning and probability/predictive algorithms, stochastically changing behavioural patterns can be recorded. This is carried out preferably, but not exclusively, in a CPU or a central processor but includes neuronal networks. These are network computers connected in the manner of nerve cells with radiating fibres which are controlled by a central software but which work largely autonomously. To input algorithms and trigger alarms, fuzzy logic known to the expert as non-sharp logic is used. Originally fuzzy logic was used to describe incomplete and/or inexact data records and process these mechanically. Today fuzzy logic is widely used in control and regulation technology, in particular when good results cannot be achieved with conventional regulators.
Using the neuronal network and fuzzy logic, adaptive self-learning algorithms of the software can detect as systematic a non-stochastic behaviour of at least one person and adapt the stored model continuously. The evaluation of such a systematic user behaviour is used by the software as a prediction basis for the most probable following actions, and is stored and used to trigger actuators. Deviations from certain systematic user behaviour can also trigger an alarm. This is not done immediately but suitably after a time delay, for example after 5 to 15 minutes.
The adaptive self-learning algorithms of the software can also receive external control signals. This is done for example via a connecting network of databases, in particular via the internet. These control signals are used to trigger actuators, also in combination with internal control signals.
In a further variant of the invention, the sensitivity is automatically adapted to the user. Here the sensitivity of an automation system on movement is increased by reducing the response threshold if at least one person is present in and/or enters the room. The heat difference then activates a second more sensitive stage and the sensor detects the finest body movements in the range from 10 to 20 cm. On each movement detected, the switch time predetermined or calculated from the stochastic behaviour of the person or persons is renewed with increased sensitivity. For details see CH,A 684449 and publication Infel-Info January 1996 pages 1 to 4.
If during an adjustable time period the total absence of persons and/or no activity is detected, the building automatic system automatically switches to alarm mode.
With reference to the automation system for performance of the process, the task according to the invention is solved in that for monitoring the presence and activity of persons at least one sensor is used per room, these sensors are networked with presence and activity-controlled control loops, and these networks contain computers with software-modifiable, deterministic and adaptive self-learning algorithms. Further and special design forms of the automation system are the subject of dependent claims.
The networks with the computers are preferably structured neuronally.
The networked sensors, essentially movement sensors of all types, depend on the geometry, structure and furnishings of the room to be monitored. A presence sensor ECO-IR 360 by High Technology Systems AG, CH-8306 Bruttisellen, for ceiling mounting allows full 360� cover. Evidently certain rooms or parts of rooms can also be screened from the monitoring if required. Also other sensors can be connected which serve merely to trigger alarms, for example a smoke alarm or thermostat.
The sensors can be networked via the electrical installation network. In particular in new buildings, the networking comprises at least one standard data bus, suitably an LON (Local Operating Network) or EIB (European Installation Bus) or PLC (Power Line Communication).
The applications of the process according to the invention are practically unlimited, in particular for the control of lighting, heating, air conditioning, ventilation, darkening, hot water preparation, control of electrical equipment such as washing machines and/or alarms etc.
The advantages of the process according to the invention and the device operated with this can be summarised as follows:
The multiplicity of possible combinations of cases need not be preprogrammed, simple rules can be applied such as for example "the heating is not switched off in the morning until everyone has been to the bathroom".
A user behaviour recognised as systematic is used as a prediction basis for the most probable stochastic following actions and corresponding actuators are triggered. The user behaviour is continuously modified automatically.
A deviation from certain systematic user behaviour can be used to trigger an alarm after a time delay.
The home and building automation system allows considerable energy saving, improves comfort and increases the safety of the user.
The state of the art and the invention are explained in more detail using the design examples shown in the drawing. These show:
FIG. 1 a known heating control system with conventional control loop and
FIG. 2 a home and building automation system according to the invention with a presence and activity-controlled control loop.
A known heating control 10 according to FIG. 1 is adapted to the comfort of a user 12 who selects the room temperature pleasant for him via a manually adjustable thermostat 14. This gives an electrical signal, the nominal value marked "+", to a summing point 16. A conventional control loop 18 leads via a PID regulator 20 to a temperature sensor 22 for the provisional temperature of a heating system 24 and from there back to the summing point 16 where the actual value marked "−" is entered to determine the nominal-actual difference.
Between the temperature sensor 22 and the heating system 24 is shown a water pipe 26 for the supply of the heating medium. A dotted arrow 28 indicates the subjective temperature perception of the user 12. If he finds this temperature too high or too low, he adjusts the thermostat 14 manually which gives a new nominal value for the summing point 16.
FIG. 2 shows a home and building automation system 30 with a presence and activity-controlled control loop 32.
A processor 34 with software comprises the adaptive home automation and modifiable behaviour pattern database 36. An arrow 38 indicates a connection to the internet.
The presence and activities of the user 12 are monitored by a movement sensor 40, in the present case a PIR regulator of the known type. The electrical signals generated by the movement sensor are supplied to a databus 42 which opens into a further databus 44 also indicated by a double arrow. This connects the processor 34 to a bus interface 46.
The bus interface 46 forms a functional unit with the presence and activity-controlled control loop 32 as indicated by a dotted rectangle 48. Electrical lines 47 branching out of the bus interface 46 open into adaptively adjustable P (proportional), I (integral) and D (differential) PID regulator 50 via which runs the presence and activity-controlled control loop 32.
The bus interface 46 also outputs electrical impulses marked "+", the nominal values, to the summing point 16. The electrical pulses marked "−" for the actual value are supplied via the control circuit 32 to form the nominal-actual control difference. P, I and D are adjusted adaptively as stated.
Depending on the continuously modified behaviour pattern of the user 12, the database 36 of processor 34 and/or the latter itself or the algorithms concerned via database 34, bus interface 46 and control circuit 36 trigger an actuator 52 which opens the water line 26 of the heating system 24. For the sake of simplicity not all of this chain is listed elsewhere, but reference is made merely to the triggering of actuator 52.
On entering the room, the user finds the room heated to the temperature he requires at the time controlled according to behaviour with minimum energy consumption.
On conversion from summertime to wintertime and vice versa, the normal daily rhythm of persons living in a household shifts by one hour. The home automation system records the modified behaviour and shifts the provision of hot water in the morning hours accordingly by this hour without any intervention of the user being necessary. The change is prepared in that a signal is received and analysed which announces summertime or wintertime.
A single person leaves the bedroom at night for a short time for example to visit the WC, but always returns at the latest 10 minutes later. If this person leaves the bedroom, but has an accident or loses consciousness, the system will derive an alarm from this. Using the fuzzy logic methods and the neuronal network, it is no longer necessary to predict and program in advance all possible cases and combinations, according to the invention it is sufficient to enter a simple rule "on abnormal behaviour, trigger an alarm after a time delay". Evidently for special cases, for example getting up to read or watch TV, the alarm is bridged automatically by movement sensors or manually by pushing a button.
In the installation of a home automation system, the starting model for user behaviour specifies that the family begin the day at 06.00 with a shower and then take breakfast in the kitchen between 06.30 and 07.00. The requirement for this model is that the bathroom is heated sufficiently early depending on the structural features for a required room temperature of for example 22� C. to be achieved at 06.00. From 06.30 the bathroom heating is switched off again. A similar procedure applies to the kitchen heating.
After some time, a timetable change applies to one of the children such that he uses the bathroom for the first time at 07.30, but does not use the kitchen at all. This behaviour deviating from the original model is recognised by the implemented algorithms of the software as systematic and the model is adapted accordingly. The bathroom heating is maintained at 22� C. until 08.00. The kitchen heating remains unchanged.
If a deviation from the usual habits occurs only sporadically, the automation system, via the stored probability functions (probability algorithms) selects an extension of the bathroom heating according to the probability of usage such that when the event occurs the quickest possible adaptation of room temperature is achieved and the total energy consumption is kept as low as possible as an extra criterion. In addition the automation system, because of the neuronal network structure of presence and activity sensors, will find that this case occurs when the person concerned has not been active accordingly in his bedroom by 06.25 at the latest.
Also additional optimisation can be carried out via external predictive information from the meteorological service. If for example a bad weather front is approaching, this can lead overnight to a temperature drop which requires the heating phase for the bathroom to begin earlier. Thanks to the prediction, the automation system according to the invention has this information before the event occurs and can trigger the heating command earlier than would be the case for example with an external temperature sensor.

The long lost work of Frederic Cailliaud and its relevance today
Mon, November 15, 2010 • 4:30 PM • WAG 214
A lecture by Andrew Bednarski, Ph.D.
American Research Center in Egypt
In 2008 ARCE began a project to translate, edit, and publish the last great work of the pioneer Egyptologist Frédéric Cailliaud. A hero in his time, Cailliaud rediscovered the ancient emerald mines of Mount Zabora, explored both the Eastern and Western Deserts, traced routes to the Red Sea, and, most famously, 'rediscovered' the pyramids of ancient Meroe. Upon his return to France he brought, along with hundreds of objects for museums, an encyclopedic knowledge of the lands of the Nile. Capitalizing on this first-hand knowledge, Cailliaud published his important Travels to the Theban Oasis and Travels to Meroe. His third, great work, however, a sort of French blending of Manners and Customs of the Ancient Egyptians and Manners and customs of the Modern Egyptians, fell afoul of technical problems and the pressures of other commitments. While a small number of volumes of the plates for this work were published the text meant to accompany it never saw the light of day. Upon Cailliaud's death, the unpublished manuscript fell into relative obscurity, where it remained for more than 100 years. ARCE's goal of combining, for the first time, the intended text and published plates, along with supporting information, is gradually being realized. This lecture will discuss Cailliaud's life, adventures, and work, as well as explain the on-going value of his long-lost manuscript to the study of ancient and modern Egypt.
Dr. Andrew Bednarski is an Egyptologist specializing in the history of the discipline. He earned his Ph.D. at Cambridge University and currently works as the Assistant to the Director for Special Projects, ARCE. Along with his historiographical interests, he has excavated in Egypt at Hierakonpolis, Abydos, Tell el-Amarna, Dakhla, Mut Temple (Karnak), and Luxor Temple. His current research interests focus on the reception of ancient Egypt in general, and the reception of ancient Egyptian material culture in particular, in western civilization.

Transcendent Sound
Making Music Better
Transcendent Sound
Making Music Better
OTL technology affords the finest in sonic reproduction. There is no question, no doubt. No other amplifier configuration can match the qualities that OTL amplification can bring to music. However, not everyone wants an OTL amplifier. They may have low impedance speakers, they may be uncomfortable with multiple output tubes, or they just want something more traditional. We recognize this and have developed a low cost transformer coupled amplifier that rivals OTL performance.
So how does it sound?
It has a very mellow, smooth sound. Music is very clear and accurate. It is not overly warm or heavy sounding. Treble is fully extended with crisp transients. It's not fair to compare a transformer coupled amplifier to an OTL in regards to clarity, quickness and openness of the sound, but in direct comparisons with the T16, the cathode follower amp has a more weighty sound with more body with a slight reduction in detail and openness. Some people actually prefer this kind of sound. Only an OTL can project music into the room with the true sense a live performance, but this come close. We feel that this design approaches the limits of what it is possible to accomplish with a transformer coupled output. Don't let the low power rating fool you. This is a very dynamic sounding amplifier. It will work well with most speakers that have an efficiency of 92 dB at one watt or higher.
What is a Cathode Follower Output?
With traditional single-ended amps, one lead of the output transformer is connected to the power supply and the other is connected to the plate of the tube, and the tube's cathode is grounded. The output tube in this configuration provides both voltage and current amplification. In this amplifier, one lead of the transformer is connected to the cathode of the tube and the other lead is grounded. The output tube provides only current amplification. This configuration dramatically improves performance because the cathode follower reduces the impedance of the output stage to less than 40 ohms while a conventional configuration has an output impedance of 700 ohms or more depending on the tube used.
If the cathode follower is so great, why doesn't everyone else use it?
Quite simply, because it is much more difficult to design. Through some clever engineering, we have been able to develop a simple, low cost circuit that incorporates the superiority of the cathode follower output.
So what specifically are the benefits of this amplifier?
1. Powerful bass. The output impedance is very low at 0.4 ohm giving clean, accurate bass transients. High current pulses are available to drive the woofer. The bottom end is down 1 dB at 30 Hz and 3 dB down at 20 Hz. Conventional single-ended amplifiers have little bass drive below 100 Hz.
2. Extended high-frequency response. The low impedance drive of the output stage easily drives transformer capacitance extending high frequency power bandwidth. The top end is down 1 dB at 50 kHz giving the amp OTL like quality.
3. Very linear, low distortion. The cathode follower is inherently a very low distortion configuration. Residual THD is less than 1% just before clipping. Distortion drops to just a few tenths of one percent at lower power levels.
4. Super quiet. It wasn't easy to do, but we were able to get the noise down to well below 1 mV. The amp is as quiet as a low noise T16, which are commonly used to drive high-efficiency horn speakers. It is much more difficult to eliminate noise from single-ended tube amps than push-pull amps like the T16. Output transformers make the problem even more difficult.
5. Loves 4 ohm speakers. Four ohm speakers can be easily driven with no loss of performance. The transformer has output taps at 4, 8 and 16 ohms allowing it to match to a wide variety of speakers.
6. Low heat. This amp is green! Total power consumption is about 100 watts. The amp can be comfortably used in small rooms and in the summer months. Glorious tube sound can be enjoyed without consuming very much energy.
Tweakers will have a ball with this one!
Transcendent Sound products are designed to be the best possible as shipped to the customer. However, we recognize that many people enjoy making modifications. To satisfy the need to tweak, the amp will incorporate the following features.
1. Aluminum chassis. Our standard chassis is stainless steel which looks fantastic. However, stainless steel is very difficult to drill and nearly impossible to punch with hand tools. Using aluminum will allow modifications to be made easily.
2. All point-to-point wiring. No printed circuit boards are used. The circuit can be changed as often as the owner desires as everything is replaceable. The simple circuit can be easily constructed. The chassis is large (17 inches by 10 inches) giving lots of room for wiring and making modifications.

1. Field of the Invention
The present invention relates generally to energy storage and conversion systems, and more particularly to a system for storing electrical energy in the form of rotational momentum and for converting direct current power into alternating current power using a rotating mass as a buffer.
2. Description of the Prior Art
A need exists for inexpensive and reliable techniques for storing large amounts of electrical energy. Several techniques have been developed in the past, but many of these solutions are not practical in many environments. For example, systems have been developed in which excess electrical power is used to drive pumps which pump water into large storage facilities. When additional power is needed, the water from the storage facilities is drawn out through turbine wheels which convert the potential energy of the stored water into electrical energy. Although such systems work well in environments where large quantities of water are readily available, they are not practical in many parts of the country where water is not readily available and where the land is often flat, making the construction of elevated reservoirs extremely difficult and complex. Furthermore, water storage systems of the type described are generally feasible only for very large power stations since they are very expensive and complex to construct.
Energy storage devices are needed throughout the world for use in conjunction with many of the energy generating techniques which have been popularized by the recent shortage of fossil fuels. For example, there is now considerable interest in generating electrical power using naturally available sources of energy such as wind energy, solar energy, geothermal energy and others. Many of these sources such as wind energy and solar energy are discontinuous in a time frame which is often not compatable with output power requirements. For example, no solar energy is available at night when there is a need for output power to drive lighting fixtures.
Thus there is a need to accumulate the energy derived from discontinuous natural sources of this type until a need for the energy develops. Naturally, such systems which remove energy from nature at no cost and store it until a need for the energy arises can be of great economic and commercial importance as the cost of fossil fuels and other techniques of generating energy increase dramatically.
It is also desirable that an energy storage apparatus for use in conjunction with energy sources of the type described be capable of converting direct current power into alternating current power since it is often easiest to convert some forms of natural energy, such as solar energy, into direct current, while most commercial appliances require alternating current power. Thus it is highly desirable that the energy storage means, in addition to providing a temporary storage function, also provide the capability of converting from direct to alternating current power.
Accordingly, it is one object of the present invention to provide a system for temporarily storing electrical energy.
A further object of the present invention is the provision of a novel system of relatively low cost for providing temporary storage of electrical power.
A still further object of the present invention is the provision of a novel system for storing electrical power in the form of angular momentum.
Yet another object of the present invention is an apparatus for temporarily storing electrical energy and for permitting conversion from direct current to alternating current power.
A still further object of the present invention is the provision of a novel system for driving a massive flywheel using electrical energy and for retrieving electrical energy in a different form from the flywheel.
A still further object of the present invention is the provision of a novel control system for operating a device for storing energy in the form of angular momentum and for retrieving the stored energy.
Briefly, these and other objects of the invention are achieved by providing a plurality of adjustably positionable drive wheels driven by direct current to accelerate a massive flywheel. A similar plurality of adjustably positionable driven wheels engage and are driven by the flywheel to turn alternating current generators for producing output power. Unused power is stored as angular momentum in the rotating flywheel.
A more complete appreciation of the invention and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, wherein:
FIG. 1 is a cross-sectional side elevation of the flywheel apparatus of the present invention;
FIG. 2 is a top view of the flywheel apparatus illustrated in FIG. 1 showing further details of the drive and generator wheel structure of the present invention;
FIG. 3 is a plan view of the lower surface of the vacuum-tight cover for the flywheel apparatus illustrated in FIG. 1;
FIG. 4 is an enlarged cut-away side view of a portion of the structure illustrated in FIG. 3 showing the details of a joint thereof;
FIG. 5 is a side elevational view of a drive wheel apparatus showing the frame structure thereof;
FIG. 6 is a sectional top view of a portion of the wheel moving mechanism of the present invention;
FIG. 7 is a partial side view of the wheel moving mechanism of the present invention showing details thereof; and
FIG. 8 is a block diagram illustrating the control system of the present invention.
Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, and more particularly to FIG. 1 thereof, the basic electromechanical apparatus of the present invention is illustrated. A pit or container wall which may be formed of concrete, steel or any other suitable material is shown surrounding the apparatus of the invention. A pit or container floor 2, which may be formed of the same material as the wall 1, supports a flanged pedestal mount 3. It will be noted that the container structure can be sunk into the ground in the form of a pit, or it can be constructed entirely above the ground as circumstances warrant.
A heavy main riser column 4 is secured to the flanged pedestal mount 3 and has an extended top member 5 of reduced diameter projecting as an extension from the upper end thereof. A thrust block 6 is positioned around the lower end of the main riser column 4 where it is supported by the flanged pedestal mount 3 for retaining the main riser column in position. Thrust bearings 7 are provided for rotatably mounting a very large flywheel 8 carried by the column 4.
The flywheel 8 is secured to the shaft 4 which is supported at its upper end by bearings 9, and may be formed of reinforced concrete, cast iron or other suitable materials capable of withstanding large centrifugal forces. The flywheel 8 is preferably a very large unit weighing between 200 and 300 tons, enabling it to store large quantities of energy, for example between 990 thousand and 5 million horsepower hours. Clearly, these figures are only exemplary, and the apparatus of the present invention can be built on much smaller and much larger scales than those described.
A vacuum tight cover 10 is provided for entirely sealing the open top of the pit containing the flywheel 8 so that the flywheel may be operated in a vacuum to reduce frictional power losses. A conventional vacuum pump 10A is preferably provided for maintaining the vacuum within the flywheel chamber.
A driver wheel frame 11 and a generator wheel frame 12 are illustrated positioned parallel to the top surface of flywheel 8 and secured at the outer radial ends thereof to the pit wall 1 and at the inner ends thereof to a mounting collar 21 resting on a shoulder 21a formed where top member 5 joins main riser column 4. The details of the wheel frames 11 and 12 are illustrated more clearly in FIG. 2 which is a top view of the structure illustrated in FIG. 1.
Referring now to FIG. 2 it is seen that there are four driver wheel frame members 11 arranged in a cross-like pattern, and also four generator wheel frames 12 similarly arranged and positioned symmetrically between the driver wheel frames. All wheel frames are secured between the pit wall 1 and the mounting collar 21 so that they are rigidly positioned above the flywheel 8 and possess the structural strength to permit large accelerating and decelerating forces to be applied to the flywheel 8. A generator wheel assembly 13 is carried by each generator wheel frame 12 and a similar drive wheel assembly 15 is carried by each drive wheel frame 11. For heavy duty or high power applications, double or multiple drive wheel assemblies as shown at 15A may be used, and similarly double or multiple generator wheel assemblies 13A can be added to the system. DC power lines 16 are coupled through a control panel 22 to each of the drive wheel frames 11 for supplying driving power to the various drive wheel assemblies 15. AC output power lines 17 are similarly coupled to the generator wheel assemblies 13 and the generator wheel frames 12 for carrying output power produced by the generators through the control panel 22 to external loads.
Attention is now directed to FIGS. 5-7 which illustrate the details of the wheel frames 11 and 12 and the wheel assemblies 13 and 15. It will be noted that the mechanical structures and configurations of the drive wheel frames and the generator wheel frames are preferably identical for economy of manufacture. Similarly, the generator wheel assemblies and the drive wheel assemblies are preferably identical. Naturally, the electrical equipment, and specifically the DC drive motors and AC generators are different from one another.
Referring now to FIG 5, an end view of one of the wheel assemblies and its driving components is illustrated. A triangular frame 40 of bridge-type construction is shown as forming the central rigid structure of the wheel frames 11 and 12. A wheel carriage 42 is slidably mounted by means of appropriate roller bearings 44 and associated guide tracks for free longitudinal movement along the triangular frame 40. The basic structural details of the triangular frame 40, the wheel carriage 42 and the roller bearing assemblies 44 are disclosed in more detail in my co-pending application Ser. No. 576,984 filed May 13, 1975. At least a pair of wheels 46 are pivotably mounted to the wheel carriage 42 by means of suitable support arms 48. Each wheel is provided with an indexing motor 23 which permits selective raising and lowering of each wheel 46 by rotating a screw 24 which cooperates with an internally threaded wheel control bracket 25, one of which is secured to each of the support arms 48. A shock adsorbing and tensioning spring 50 is positioned around the screw 24 to maintain the wheels 46 in firm engagement with the surface of the flywheel 8.
An electric motor 14 (or a corresponding generator) is coupled to the axle of each wheel 46 for driving or being driven by the wheel. In the case of the DC drive wheels, DC motors are coupled to the axle of each wheel for supplying power to the wheel whereby the flywheel 8 is rotated. In the case of the generator wheels, a generator is coupled to the axle of each wheel 46 for being driven by the wheel 46 to remove energy from the flywheel 8.
The mechanism for moving the wheel carriage 42 radially along the top surface of the flywheel 8 is also illustrated in FIG. 5 and includes a bracket 33 securely mounted to the triangular frame 40. On the bracket is mounted a chain sprocket 30 carrying a chain 38, and supported by means of a shaft 35 rotatably mounted in a bearing ear 34. The sprocket 30 is driven through a gear assembly contained in a housing 32 and coupled to the shaft 34. The gear assembly is driven by an indexing motor 36 mounted, along with the gear housing 32 to the bracket 33. A drag link 37 is secured to the wheel carriage 42 and to the chain 38 for coupling the wheel carriage assembly with the chain and its driving mechanism.
A side view of the apparatus illustrated in FIG. 5 is shown in FIG. 7, further illustrating the manner in which the wheel carriage 42 slides along the triangular frame 40 under control of the drive assembly acting through the chain 38. As shown in FIG. 7, a pin frame 39 is secured to one end of the triangular frame and provides a means of securing the triangular frame to the pit wall 1 of the overall structure as illustrated in FIG. 1. The pin frame 39 preferably includes an interior slot (not shown) in which a corresponding support member rigidly fixed to the pit wall 1 may fit. A heavy duty cotter pin is then inserted through the cooperating members to removably mount the triangular frame 40 to the pit wall.
FIG. 6 illustrates a top view of the interior end of each of the wheel frames 11 and 12 showing the manner in which the wheel frames are coupled to the top member 5. As shown in FIG. 6, the frame 40 includes an aperture at the end portion thereof for accommodating a bracket frame mount 26 secured to the column top stem member 5 of main riser column 4. A heavy duty cotter pin 27 in inserted through these corresponding members to removably secure each of the triangular frames 40 to the central mounting collar 21. An idler sprocket 30A, maintained in position by a suitable bracket 29 and pin 31, is mounted to the triangular frame 40 for supporting the non-driven end of chain 38.
Attention is now directed to FIGS. 3 and 4 which illustrate in more detail the structure of the cover panel 10. The cover panel 10 is preferably divided into a number of segments, of which 8 are shown. Naturally, a larger or smaller number of segments may be used depending upon the size of the overall assembly. Each of the illustrated segments is supported at its edge portion by a sturdy frame member 19, such as a steel girder for example, as shown in FIG. 4. A resilient sealing gasket 20 is positioned along the top surface of the support girder 19 and is partially inserted into a retaining groove 20A. Each of the individual panels 10, which may be constructed of glass, fiberglass, steel or any other equivalent material includes a channel-shaped end portion 10A which is adapted to be positioned over the portion of the gasket 20 seated in the channel 20A. The weight of each panel 10 presses into the gasket 20 providing an air-tight seal. When a vacuum is created within the flywheel chamber, atmospheric pressure forces the channel portions 10A of each panel 10 deeper into the gasket material creating an ever-tightening seal.
Reference is now directed to FIG. 8 wherein the control system of the present invention is illustrated in the form of a block diagram. All of the components illustrated in FIG. 8 are conventional electronic or electrical devices which are easily commercially available, as will be understood by those skilled in the art. Thus, none of the individual components illustrated comprises an aspect of the present invention. However, the combined system illustrated in FIG. 8 which accomplishes the necessary controls for operating the apparatus of the present invention is considered a unique aspect of the invention.
A DC power input line 16 is shown for supplying the input energy to the system. The input power is supplied to a DC motor control 52 which distributes the input power to DC motors 14 which drive their associated DC drive wheels which mechanically engage the flywheel 8 for accelerating the flywheel. The amount of input power is measured by the DC motor control 52 for determining how many of the individual DC drive motors need be energized to efficiently transfer the amount of input power to the flywheel 8. If a large input power is supplied over line 16, the motor controller energizes a maximum number of individual DC drive motors for driving as many of the DC drive wheels as possible in order to provide a maximum acceleration to the flywheel 8 and to build its speed rapidly to store the large flux of input power. Conversely, only a small input power is received, a minimum number of drive motors are energized to accelerate the flywheel more slowly, thereby storing only the smaller amount of power being supplied.
As the flywheel 8 is accelerated, a magnetic flywheel speed sensor 54 monitors the speed of the flywheel by sensing the passage of magnetic inserts 54A carried by the fly heel, and supplies this information to a position control 58 for the DC drive wheels and to a position control 60 for AC generator wheels. The position control also receives speed signals from the individual DC drive wheels through magnetic wheel speed sensors 56 associated with each wheel. In response to these wheel speed signals, the position control supplies appropriate indexing signals to the vertical indexing motors 23 and the radial indexing motors 36. The vertical indexing motors 23 raise and lower the various wheels to place them in contact with the flywheel or remove them from contact with it, while the radial indexing motors move the wheels along the radius of the flywheel. The position control is synchronized with the DC motor control 52 so that as a first pair of wheels is accelerated to a selected maximum desirable speed, the position control energizes the vertical indexing motors to place a second pair of drive wheels in contact with the flywheel at the same time that the DC motor control supplies power to the motor driving the additional wheels. Similarly, when the wheel speed sensors indicate that the wheels are turning at a maximum desirable rate for a given flywheel speed, and yet additional power is being received to accelerate the flywheel, the position control energizes the radial indexing motors to move the drive wheels toward the center of the flywheel so that the flywheel speed can be accelerated for a given speed of the drive wheels. Thus, the position control selectively moves the drive wheels along the radius of the flywheel for maintaining efficient wheel speeds for accelerating the flywheel, and also controls the number of drive wheels engaging the flywheel.
A similar arrangement is provided for controlling the AC generator wheels and the AC generators 62 driven by them. An AC generator wheel position control 60 controls vertical indexing motors 23 and radial indexing motors 36 in accordance with signals developed by magnetic wheel speed sensors 56, magnetic flywheel speed sensor 54 and output power control 64. The wheel speed and flywheel speed signals together with the control signal from the output power control 64 are used to control the position and number of AC wheels being driven by the flywheel at a given interval. The power control 64 monitors the load power consumption in conjunction with the speed of the operating AC generator wheels. If more power is needed to adequately supply the load, the position control is directed to energize additional vertical indexing motors 23 to cause more AC wheels to engage the flywheel 8 and thereby to generate more power. A synchronism detector 66 is coupled to all of the individual AC generators 62 to maintain all generators in synchronism for providing a uniform AC output.
To provide an example of normal operation, it is assumed that the flywheel 8 is initially at rest. A supply of DC current is then fed through the line 16 to the DC drive wheels. The DC drive wheels spin the flywheel up to a minimum rpm at which the AC generators will run at the proper speed to produce AC power of the desired frequency. Both the AC and DC wheels normally start near the outer periphery of the flywheel and are gradually moved toward the center of the device as the flywheel speed increases under the control of the various wheel positioning networks.
The system of the present invention is very efficient in operation and is easily assembled and serviced. The cover panels 10 may be easily removed for access to the main working components simply by reducing the vacuum within the flywheel chamber. Similarly, the individual wheel frames 11 and 12 may be readily removed simply by pulling the mounting pins which secure the ends of each frame in position. Wheel carriages can be readily removed and replaced as units with little difficulty. Similarly, drive wheel and generator wheel carriages can be replaced with carriages having greater numbers of wheels for increasing the power storage and output capacity of a given unit, as well as for increasing the response time of the unit.
Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
