The Rotary Piston Array Machine -- Air-Sea Temperature Difference Engine -- Solarthermal Power Generator The Rotary Stirling Engine The Wave Pump Heat Engine With No Compressor Portable Tent Platform The rotary piston array (RPA) is the possibly most compact and most elegant machine to transform the volumetric change of gas into shaft work and vice versa. It can be used as pneumatic motor, steam engine, gas compressor, vacuum pump and the like, but also as part of new heat or combustion engines which – like the Stirling engine – open new ways to harvest renewable energy. Other possible uses are refrigeration and air-conditioning. The idea has been overlooked for at least 110 years, as some old patents indicate, and it seems to have been reinvented several times (e.g.
The machine comprises an array of equally shaped twisted rotors with parallel axes. Air-Sea Temperature Difference Engine Solarthermal Power Generator Wellenpumpe.pdf (German) ... What Is the Easiest Way to Power a Lightbulb. Tesla - Master of Lightning: A Weapon to End War. Tesla inherited from his father a deep hatred of war. Throughout his life, he sought a technological way to end warfare. He thought that war could be converted into, "a mere spectacle of machines.
" In 1931 Tesla announced to reporters at a press conference that he was on the verge of discovering an entirely new source of energy. Asked to explain the nature of the power, he replied, "The idea first came upon me as a tremendous shock... I can only say at this time that it will come from an entirely new and unsuspected source. " War clouds were again darkening Europe. The idea generated considerable interest and controversy. By 1937 it was clear that war would soon break out in Europe. What set Tesla's proposal apart from the usual run of fantasy "death rays" was a unique vacuum chamber with one end open to the atmosphere.
Of all the countries to receive Tesla's proposal, the greatest interest came from the Soviet Union.
