ABSTRACT:
An air powered drive system for a vehicle such as an automobile or a propeller driven aircraft. In a land vehicle air pumps are connected to drive, or be driven by, each wheel. At least two air storage tanks are connected to the air pumps. A fuel is burned in one tank to provide hot, high pressure air that can be directed to selected air pumps to drive associated wheels. Meanwhile, other air pumps connected to a cool, lower pressure tank are driven by an associated wheels to act as an air compressor to compress cool ambient air in the tank. When air pressure in the heated tank drops, combustion is shut off there and begun in the other tank and the driving and filling tanks and pumps are reversed. Similarly, two such tanks are connected through air pumps to an aircraft propeller shaft. Alternately, on tank is heated to produce hot, high pressure air to drive one air pump while the other air pump is driven by the shaft to compress air in the cooler tank. When pressure in the heated tank decreases, tank operation is reversed. In the land vehicle version, additional energy can be saved during braking and through small pumps connected to shock absorbers. Also, a roller mounted band can be provided around the vehicle to reduce collision damage.
