Alternative fuel solutions for automobiles:
The principle of running the LN2000Car is like that of steam engine, except there is no combustion involved. Instead liquid nitrogen at –320oF (-196oC) is pressurized and then vaporized in a heat exchanger by ambient temperature of the surroundings air. This heat exchanger is like the radiator of a car but instead of using air to cool water, it uses air to heat and boil liquid nitrogen. The resulting high pressure nitrogen gas is fed to an engine that operates like a reciprocating steam engine, converting pressure to mechanical power. The only exhaust is nitrogen, which is major constituent of our atmosphere.
