Claim 3:
4. A method for releasing the energy of liquid air 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 of 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; and
e. directing said first turbine exhaust to said liquid air recuperator to assist in said heating and vaporizing of said pressurized liquid air and then into a separator and separating liquid carbon dioxide from said first turbine exhaust;
f. directing said first turbine exhaust after separation of said liquid carbon dioxide to a second turbine and extracting power from said first turbine exhaust.
