Claim 12:
13. A method for liquid air energy release comprising:
a. providing liquid air at a pressure of greater than 0.52 MPa;
b. directing said pressurized liquid air to a liquid air recuperator to heat and vaporize said pressurized liquid air and producing vaporized air;
c. directing said vaporized air to a combustor and burning a fuel in the presence of said vaporized air and producing combustor exhaust;
d. directing said combustor exhaust to a first turbine and extracting power from said combustor exhaust and producing a first turbine exhaust;
e. directing said first turbine exhaust to an exhaust air recuperator to assist in heating of said exhaust air followed by a water separator and separating liquid water from said first turbine exhaust;
f. directing said first turbine exhaust emerging from said water separator through said liquid air recuperator followed by a carbon dioxide separator and separating liquid carbon dioxide from said first turbine exhaust and providing said first turbine exhaust gas that is substantially devoid of carbon dioxide and water;
g. directing said first turbine exhaust that is substantially devoid of carbon dioxide and water through said exhaust gas recuperator and heating said first turbine exhaust gas and directing said heated first turbine exhaust gas through a second turbine and extracting power.
