Abstract

An electric power system has an air compressor unit with a reservoir tank, an air powered motor and an electric generator. The air compressor unit has an air compressor that provides compressed air to the reservoir tank. The air compressor is driven by an electric motor. The air powered motor is driven by compressed air from the reservoir tank. The air powered motor provides rotary power to an input shaft of the electric generator, wherein the generator produces electrical power. The system can be mounted onto a mobile platform for ease of transport. Also, storage batteries can be connected to the electric output of the generator. The output of the batteries can be connected to the electric motor of the air compressor unit.
