HOW UNCONVENTIONAL STIRLING ENGINES CAN HELP CONSERVE ENERGY

Unconventional Stirling engines, with either a free power piston or free displacer, can efficiently use a wide variety of fuels, including dried organic matter, a major unused fuel resource. Both computer simulations and engine tests have demonstrated self starting and single-valve control of an engine producing hydraulic power from heat without intervening shaft power. Direct hydraulic power for vehicles is evaluated as is a mechanical power concept particularly attractive because of thermally regenerative braking. Finally a design concept for a double-Stirling- engine chiller is presented which can use 200 deg F heat from a flat plate solar collector or higher temperature combustion heat sources to more efficiently produce heating and cooling for buildings than is now possible.
