Goal
Provide a compact, lightweight energy storage/ generation system that can replace batteries with up to ten times greater capacity.
Problem
Limited energy density and weight of conventional batteries for vehicles and portable power.
Concept Summary
A mechanical rotary piston engine that combusts conventional fuels and uses an electromagnetic converter (induction armature, coils, magnetic elements) to directly convert the piston's mechanical motion into electrical energy, eliminating the need for a separate generator, starter, or gearbox.
Detailed Description
The RPG consists of a rotary piston sliding inside an epitrochoid-shaped housing forming rotor chambers. An eccentric lobe drives the piston, while a power converter with armature and coils converts mechanical motion to electricity during a power stroke and can also drive the piston using electrical energy in other strokes. The engine can run on gasoline, kerosene, propane, natural gas, ethanol, methanol, or hydrogen. It may include thermal controllers, reaction triggers (spark plug, igniter), and an energy management system with storage devices. The design is intended for use as a range-extender in electric vehicles or as a portable power source.
