AWE HAWP. What is "low" for some workers is "high" for others. 1796 George Pocock used traction mode to travel in vehicles over land roads. 1827 George Pocock's book ‘The Aeropleustic Art’ or 'Navigation in the Air by the Use of Kites or Buoyant Sails' was published. Pocock described use of kites for land and sea travel. The book was republished several times. 1833 John Adolphus Etzler saw HAWP blossoming at least for traction. 1864? Book's chapter Kite-Ship well describes key dynamics of HAWP used for tugging ships by kites. John Gay's: or Work for Boys. Chapter XVIII in the Summer volume. 1935 Aloys van Gries stands as a strong early patentee of high-altitude wind power; he taught various kite systems for use in generating electricity in his DE 656194 C patent: Durch Drachen getragene Windkraftmaschine zur Nutzbarmachung von Hoehenwinden 1943 Stanley Biszak instructed using potential energy in free-flight for converting ambient winds impacting turbine to drive electric generator to charge batteries. 1967 Richard Miller, former editor of Soaring magazine, published book Without Visible Means of Support that describes the feasibility of free-flight coupled non-ground-moored kites to capture differences in wind strata to travel across continents; such HAWP is the subject of Dale C. Kramer's contemporary patent application. 1973? Hermann Oberth In the appendix of his book Primer for Those Who Would Govern there are sketches and a photograph of a model of the Kite Power Station from the Oberth Museum. 1977 April 3, 1977, invention declared. On September 21, 1979, Douglas Selsam notarized his kite-lifted endless chain of airfoils HAWP system, generic type that would later show in Dutch astronaut Wubbo Ockels' device called LadderMill described in a patent of 1997. Douglas Selsam conceived his Auto-oriented Wind Harnessing Buoyant Aerial Tramway on April 3, 1977. On the Selsam notarized disclosure of invention was placed a date of Sept. 20, while the notary placed the final signing on Sept. 21, 1979. notes and drawings. 1979 Professor Bryan Roberts begins giromill gyrocopter-type HAWP wind generator development. 1980 Miles Loyd publishes an article on the crosswind kite power. 1986 Bryan Roberts' AWE HAWP rotor generates electricity and lifts itself in tethered flight. 1992 Free Rotor WO/1992020917 Free Rotor by JACK, Colin, Humphry, Bruce (one man).
