Power generation:
simply by oscillating movements
The BEETRON ® power generator consists of two opposed pistons, oscillating in a cylinder without a crankshaft. By moving magnets, an electric current is induced in the surrounding copper windings.
"Perfection is achieved,
 not when there is nothing more to add,
 but when there is nothing left
 to take away"
