ABSTRACT:
A wheel having a plurality of vanes which extend centrally out to the periphery thereof, is rotatably mounted on the walls of a main compartment. A first liquid is contained within this main compartment. A second liquid having a substantially lower boiling temperature than the first is contained within a second "boiler" compartment, the second compartment being mounted in the first and at least partially submersed in the first liquid. A source of heat is applied to the first compartment to heat this compartment and the liquid contained therein to a high enough temperature so as to cause the second liquid to boil. The vapor generated by virtue of the boiling of the second liquid is conveyed to a location beneath the wheel where it is released through port means such that the vapor bubbles rise in the first liquid and in rising are caught within the vanes of the wheel, which then exerts a buoyancy force, thereby rotatably driving the wheel. The vapor exits near the top of the wheel, then out of the main compartment. The wheel is coupled to drive means outside of the compartment, the drive means being employed to drive a mechanism, as may be desired.
