Liquid nitrogen engine Wikipedia

A liquid nitrogen vehicle is powered by liquid nitrogen, which is stored in a tank.Traditional nitrogen engine designs work by heating the liquid nitrogen in a heat exchanger, extracting heat from the ambient air and using the resulting pressurized gas to operate a piston or rotary motor.Vehicles propelled by liquid nitrogen have been demonstrated, but are not used commercially.
