Abstract:
1. A nitrogen pressure-based engine device ( 100 ) comprising: (a) a main engine chamber ( (b) a storage tank ( (c) a heater/vaporizer chamber ( (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 ( (f) a shut-down valve ( (g) an emergency pressure relief component ( 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.
