1. A heat engine that used a thermal compressor to power a compressed gas drive, where gas compression is mechanically uncoupled from the output drive and where a quasi-constant-pressure process is used and comprising:

  • (a) a thermal compressor (TC) which receives gas at engine ambient pressure and discharges it at a higher pressure, and comprising;

    a closed container and a displacer, means of bringing heat into the engine, a cooler that rejects heat, a regenerator, a region or tank for accumulating low-pressure gas, a region or tank for accumulating high-pressure gas, a pair of pump check valves and a piping set that connects the elements;

    (b) a displacer drive system which receives power from a controller and outputs mechanical power to a displacer; and

    (c) a compressed gas drive that recieves high-pressure gas from the TC, transforms it into output mechanical shaft power and discharges low-pressure gas to the TC.
