A cycle engine. converting thermal energy to electricity includes a cylinder housing having a piston having two oppositely disposed heads and mounted for reciprocating inside the cylinder. The cylinder is disposed between a hot zone to supply hot gas to one piston head and a cold zone to receive discharged hot gas from another piston head, and to transform the discharged hot gas into a liquid. The hot zone supplies hot gas into the first piston head, while the second head discharges hot gas to the cold zone. This action creates a pressure differential between the two piston heads that causes the piston heads to move in one direction. Thereafter, the hot zone supplies hot gas to the second piston head, while the first piston head discharges hot gas to the cold zone, thereby creating pressure differential between the heads causing the piston to move in another direction. The piston is provided with a permanent magnet coupled to electric coil. When the piston reciprocates, it creates a magnetic influx in the electric coil, which is transformed into electricity in the coil.
A cycle engine for converting thermal energy to electrical energy comprising an elongated cylinder housing a piston disposed between a hot zone and a cold zone and having a surface communicating fluidly with said hot zone to receive hot gas and another surface communicating fluidly with said cold zone to discharge gas to said cold zone, said housing having opposite end portions, said piston having first and second oppositely disposed heads mounted for reciprocation in said housing, said piston being reciprocable between one position in which said first head receives hot gas from said hot zone and said second head exhausts hot gas to said cold zone, and another position in which said second head receives hot gas from said hot zone and said first head discharges hot gas to said cold zone, said piston carrying at least one permanent magnet and stationary coil means outwardly of said cylinder coupled to said at least one permanent magnet to generate electricity in said coil means when said piston reciprocates.
A cycle engine for converting thermal to electrical energy comprising a housing disposed between a hot zone supplying hot gas to said housing and a cold zone receiving discharged gas from said housing and having one surface having spatially distanced first and second gas ports, another surface having spatially distanced third and fourth gas ports, said housing having an elongated cylinder having opposite end portions, a piston mounted for reciprocation in said cylinder between one position and another position, said piston having first and second opposite heads, wherein in said one position said hot zone provides hot gas to said first head through said third port while said second port discharges gas from said second head to said cold zone, and wherein in said another position said hot zone provides gas to second head through said fourth port while said first port discharges gas from said first head to said cold zone, a magnet mounted for movement with and on said piston, an electrical coil means coupled to said magnet and disposed outwardly of said housing to generate electricity in said coil means when said piston reciprocates.
