My invention is simple; I just haven't had the money to see if it works. It is called a fluid dynamic generator. It uses the simple refrigeration cycle except a condenser and evaporator are replaced with two cold plates, one hot and one cold. The compressor is a 12-24 volt danfoss 40 watt. About 20 - 40 peltier or thermoelectric elements are sandwiched between the two cold plates. After start up and plates are cold and hot, switch over to thermo elements to run the compressor. The compressor only uses the same amount of power to pump those gasses and fluids, so if I have 20-40 elements at 90 watts each, only a few are needed to keep the compressor running; the rest can power up batteries/electronics.
