Patent ID: 7043920

Claim:
A combustion engine providing clean power for various applications and featuring low NOx production and low CO2 release into the atmosphere, comprising in combination; a source of air, the air including nitrogen and oxygen; a source of fuel, the fuel including hydrogen and carbon; an air separator having an inlet coupled to said source of air, a nitrogen separator, an oxygen enriched air outlet, and a nitrogen outlet separate from said oxygen enriched air outlet, such that at least a portion of the nitrogen is removed from the air entering said inlet; a fuel combustor, said fuel combustor receiving fuel from said source of fuel and oxygen enriched air from said outlet of said air separator through an oxygen enriched air inlet adapted to deliver substantially H2O free oxygen enriched air into said fuel combustor, said combustor combusting the fuel with the oxygen enriched air to produce elevated pressure and elevated temperature combustion products including H2O and CO2, said combustor having a discharge for said combustion products; a combustion products separator which separates at least a portion of the H2O from other combustion products including CO2 coupled to said discharge and including an H2O outlet and an exhaust for the other combustion products including CO2; a compressor coupled to said exhaust, said compressor pressurizing fluids passing there through to a pressure above atmospheric pressure; and a terrestrial formation injection system downstream from said compressor, said injection system coupled to said compressor and to a terrestrial formation beneath the atmosphere, said terrestrial formation capable of holding CO2 therein.
