Patent ID: 8495879

Claim:
A compressed air engine system for use in propelling a vehicle, said compressed air engine system comprising: a compressed air tank having an inlet and an outlet; a compressed air motor having an inlet in fluid communication with said compressed air tank outlet, and an outlet; a first heat exchanger connected in proximity to the inlet of said compressed air motor, and a second heat exchanger connected in proximity to the outlet of said compressed air motor; a thermoelectric cooler in heat transfer communication with said first and second heat exchangers, said thermoelectric cooler absorbing heat from said second heat exchanger and transferring heat absorbed therefrom to said first heat exchanger, whereby the pressure differential across said compressed air motor is increased; a Magnus rotor assembly having housing with an air an inlet and an air outlet, said housing containing a Magnus rotor configured for rotation about an axis, whereby air flowing from said housing inlet to said housing outlet flows across said Magnus rotor thereby creating a force; a fan, having an inlet in fluid communication with the outlet of said housing, and an outlet; and a compressor having an inlet in fluid communication with said fan outlet, and an outlet in fluid communication with the inlet of said compressed air tank.
