Claim 8:
9. A apparatus for liquid air energy release comprising:
a. a liquid air storage apparatus containing liquid air and a cryogenic pump fluidly connected to said liquid air storage apparatus wherein said cryogenic pump is configured to provide pressurized liquid air at a pressure of greater than 0.52 M Pa;
b. a liquid air recuperator fluidly connected to said cryogenic pump wherein said liquid air recuperator is also connected to a carbon dioxide separator for removal of liquid carbon dioxide and to a water separator for removal of water from a first turbine exhaust, wherein said liquid air recuperator is configured to heat said pressurized liquid air and produce vaporized air;
c. a combustor fluidly connected to said liquid air recuperator configured to burn a fuel in the presence of said vaporized air and produce combustor exhaust;
d. a first turbine fluidly connected to said combustor configured to extract power from said combustor exhaust and produce said first turbine exhaust wherein said first turbine exhaust is fluidly connected to an exhaust air recuperator which exhaust air recuperator is fluidly connected to said water separator and said water separator is fluidly connected to said liquid air recuperator and said liquid air recuperator is fluidly connected to said carbon dioxide separator and said carbon dioxide separator is fluidly connected to said exhaust air recuperator; and
e. a second turbine fluidly connected to said exhaust air recuperator to extract power from said first turbine exhaust.
