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. Ideas - TREEFINDER. Green design will save the world. An artificial leaf and a gallon of water could generate enough energy to power your house for a day.
