1. A nitrogen pressure-based engine device (100) comprising:

  • (a) a main engine chamber (110) comprising a nozzle block (380) and a turbine vacuum pump (140), wherein a turbine blade system (120) is disposed in an inner cavity of the main engine chamber (110);

    (b) a storage tank (130) for storing liquid nitrogen, the storage tank (130) comprises an evacuation port (217) for evacuating liquid nitrogen if needed;

    (c) a heater/vaporizer chamber (320) for converting liquid nitrogen to high pressure gas nitrogen, wherein the heater/vaporizer chamber (320) is fluidly connected to the storage tank (130) via a first line (210) and the heater/vaporizer chamber (320) is fluidly connected to the nozzle block (380) of the main engine chamber (110) via a second line (220);

    (d) a pump operatively connected to the heater/vaporizer chamber, the pump functions to pump high pressure gas nitrogen from the heater/vaporizer chamber to the nozzle block of the main engine chamber;

    (e) a pressure condenser (160) for condensing nitrogen to liquid nitrogen, the pressure condenser (160) is fluidly connected to the main engine chamber (110) via a third line (230), the pressure condenser (160) is fluidly connected to the storage tank (130) via a fourth line (240);

    (f) a shut-down valve (460) operatively connected to the turbine blade system, the shut-down valve (460) is activated if the turbine blade system reaches a critical speed, the shut-down valve causes the engine device to shut down and(g) an emergency pressure relief component (218) operatively connected to the turbine blade system, wherein if the turbine blade system reaches a critical pressure the emergency pressure relief component (218) is activated to relieve pressure in the turbine blade system;

    wherein liquid nitrogen flows from the storage tank to heater/vaporizer chamber where it is converted to high pressure gas nitrogen, wherein the high pressure gas nitrogen flows from the heater/vaporizer chamber to the main engine chamber via the nozzle block, wherein the high pressure gas nitrogen in the main engine chamber drives rotation of the turbine blade system, wherein the high pressure gas nitrogen then flows from the main engine chamber to the pressure condenser wherein the high pressure gas nitrogen is condensed to liquid nitrogen, the liquid nitrogen then flows from the pressure condenser to the storage tank.
