Abstract
A free-piston linear generator wherein the piston is a magnet propelled into reciprocating motion inside a non-conducting cylinder around which is wrapped one or more induction coils. The magnet-piston may be propelled into motion using either internal combustion of a diesel aerosol in a two-stroke or 4-stroke configuration, with ignition provided by compression, or by steam pressure provided by an external boiler. Sensor-controlled exhaust, fuel-intake, and air-intake valves are located at either end of the cylinder, although only a single intake valve would be required in a steam version. As the magnet-piston moves in the cylinder, the power stroke on one side of the magnet-piston is the compression stroke on the other side. The movement of the magnet-piston induces an electric current in the induction coil, by which energy is drawn from the engine as useful work.
