Ask HN: What should I do with an unlimited water supply?
I'm a college student in an off-campus apartment complex separate from the university. My apartment complex does not charge for water (hot water included). I've been trying to think of a way to make use of the water supply that exceeds traditional use. Do you guys have any cool ideas? Some of the things I've thought about:<p>1)Electricity generator. This would most likely be from kinetic energy rather than heat. The sink is a couple feet above the ground and the shower head is about 7 feet above the ground. The water doesn't get hot enough to boil for steam energy (although I did find a company that makes a device that generates electricity from a temperature differential [http://www.ergenics.com/])<p>2) Some sort of room heater. Maybe grab a water pump, an insulated tub, and some copper pipe to run through my room for a space heater/cooler.<p>This is really all I've got at this point. I'd love to hear from you guys!
