Closed electropneumatic system for propulsion

An electropneumatic torque generating system using a pneumatic engine and having a first tank connected to a first of a pair of manifolds with a first discharge connection arrangement so as to be capable of discharging portions of any of the operating gas in the first tank through the first discharge connection arrangement into the first manifold. The system further includes a first gas compressor to thereby discharge operating gases at greater pressures with the first gas compressor inlet being connected to a second of the pair of manifolds through a first input collection connection arrangement so as to be capable of receiving operating gases from that manifold through the first input collection connection arrangement that have flowed from the first manifold. There is further included a second tank being connected to the outlet of the first gas compressor through a first output collection connection arrangement so as to be capable of receiving therein operating gases that have flowed through the first gas compressor.
