Claim 0:
1. An air re-liquefaction system comprising:
a prime mover that uses a fuel and generates exhaust gas;
a re-liquefier comprising:
an active regenerator matrix;
an electric driven rotating magnet that rotates around said active regenerator matrix;
an absorption heat exchanger;
a rejection heat exchanger;
inlet and outlet valves of said absorption heat exchanger; and
inlet and outlet valves of said rejection heat exchanger;

a turbo-charger comprising a drive-turbine and a liquefier compressor;
an absorption flow path comprising:
a cryo-recuperator;
a cryo-mixing junction;
a liquid air dewar that stores liquid air; and
said absorption heat exchanger of said re-liquefier;

a rejection flow path comprising:
said liquefier compressor of said turbo-charger;
an after-cooler;
a rejection flow path heat exchanger; a cryo-expander; and
said rejection heat exchanger of said re-liquefier;

a cryo-motor-compressor; and
an electric regulator, wherein said electric regulator receives power from said prime mover and provides power to at least:
said cryo-motor-compressor;
said electric driven rotating magnet of said re-liquefier; and
said inlet and outlet valves of said absorption and rejection heat exchangers;

wherein:
pressure of the exhaust gas generated by said prime mover drives said liquefier compressor of said turbo-charger through said drive-turbine of said turbo-charger;
said re-liquefier absorbs and rejects heat through an internal fluid under control of said inlet and outlet valves of said absorption and rejection heat exchangers;
within said absorption flow path:
atmospheric intake air enters said air re-liquefaction system and is cryogenically cooled in said cryo-recuperator;
the cryogenically cooled atmospheric intake air is provided to said mixing junction;
liquid air from said liquid air dewar is also provided to said cryo-mixing junction;
said cryo-mixing junction mixes the cryogenically cooled atmospheric intake air and the liquid air and produces prime mover intake air and absorption air;
the prime mover intake air is:
provided to said cryo-motor-compressor and compressed;
heated in said cryo-recuperator; and
provided to said prime mover;

the absorption air is provided to said absorption heat exchanger of said re-liquefier, thereby transferring latent heat of the absorption air to said re-liquefier; and
the absorption air is then provided to said liquid air dewar as liquid air; and

within said rejection flow path:
atmospheric intake air enters said air re-liquefaction system and is compressed in said liquefier compressor of said turbo-charger into heat rejection air;
the heat rejection air is further cooled in said after-cooler;
the heat rejection air is further cooled in said rejection flow path heat exchanger;
the heat rejection air is further cooled by expansion in said cryo-expander;
the heat rejection air is provided to said rejection heat exchanger of said re-liquefier, where temperature lift by a magneto-caloric effect of said re-liquefier enables transfer of latent heat of the absorption air to heat the heat rejection air; and
the heat rejection air is heated in said rejection flow path heat exchanger and discharged to atmosphere.
