• Free piston technology is the most compact system to combine a combustion engine with a generator. The engine is by far smaller, lighter and more efficient than conventional power generators.

  • Our BEETRON Free Piston Generator consists of two opposed pistons, oscillating in a cylinder without a crankshaft. Electric current is induced in the surrounding copper windings by moving magnets.

  • ​Unchained from its strictly sinusoidal stroke, a faster piston acceleration is the key to a substantially higher efficiency - combining ultra high compression ratio, less heat loss, and less friction.
