Abstract
An apparatus for generating power from the temperature difference between two bodies of fluid, one of which is heated by trapping solar energy in a dome and the other one of which is cooled by wind passing beneath an airfoil. A pair of heat exchange basins are provided into which hot and cold fluid is supplied, with heat exchange coils disposed therein for developing a differential pressure which is transmitted to opposite sides of a piston. The fluid temperature in each heat exchange basin is reversed by gravitational action so that piston motion can be reversed for pumping action.
