Compressed air driven system

A method for operating a pneumatic motor driven vehicle comprising:

• providing a compressed air storage vessel;
• a pneumatic motor configured to receive compressed air from the compressed air storage vessel, wherein the pneumatic motor is coupled to a multi-speed transmission configured to rotate a primary drive shaft, the multi-speed transmission having a first power take off drive configured to rotate a first auxiliary shaft and a second power take off drive configured to rotate a second auxiliary shaft;
• a first air compressor coupled to the first auxiliary shaft, wherein the first air compressor is configured to refill the compressed air storage vessel;
• a second air compressor coupled to the second auxiliary shaft, wherein the second air compressor is configured to refill the compressed air storage vessel;
• at least one generator attached to a drive shaft of the first air compressor;
• and
• a throttle configured to provide compressed air at a predetermined volume and predetermined pressure to the pneumatic motor from the compressed air storage vessel;
• initially pressurizing the compressed air storage vessel using an auxiliary air compressor;
• adjusting the throttle to provide compressed air at the predetermined volume and predetermined pressure to the pneumatic motor, wherein the pneumatic motor rotates the first auxiliary shaft and first air compressor, the second auxiliary shaft and second air compressor;
• and the primary drive shaft.
