Technical Examples
  1. A two stroke steam-to-vacuum engine comprises a plurality of cylinders (500, 502) each cylinder having a piston (504, 510), a piston rod (506, 512), and a steam chamber (508, 514), the piston rods connected for synchronous movement such that each piston is reciprocally moveable between an expanded position and a collapsed position. Admission of steam at 3-5 p.s.i. above atmospheric pressure into the steam chambers (508, 514) is controlled by steam valves (522, 524) and exposure of the steam chambers to a vacuum is controlled by vacuum valves (548, 550). Steam is supplied to the steam chambers (24, 38) through a boiler 520, a solar power source, or an alternative fuel of choice. An auxiliary vacuum tank (572) may be isolated from a primary vacuum tank (554) to replenish the vacuum in a condensate collector tank (560) after removal of condensate. Auxiliary vacuum pumps (614, 616), driven by power from cylinders (500, 502), replenish the vacuum in the auxiliary vacuum tank (572) leaving the main vacuum pump (570) to support the primary vacuum tank (554).
