Abstract
A power system includes a device configured to store pressurized fuel. An air motor having an air motor output member is in fluid communication with the storage device, and is configured to transfer the mechanical energy of the fuel to the air motor output member. A chemical energy conversion system is in fluid communication with the air motor to receive fuel therefrom. The chemical energy conversion system is configured to convert the chemical energy of the fuel to another form of energy, such as mechanical energy or electrical energy. The power system of the invention recovers at least some of the energy expended in compressing fuel in the storage device
