Claim 10:
11. A method for cascaded energy recovery, said method comprising the steps of:
a) providing heat generated by a first heat source to an n prime mover, wherein the n prime mover generates n prime mover exhaust heat when the heat is provided from the first heat source to the n prime mover, said step a) comprising the steps of:
recovering the heat to an n pre-heater; and
transferring the heat to the n prime mover through an n heat exchanger;

b) providing all of the n prime mover exhaust heat to an n+1 prime mover, wherein the n+1 prime mover generates n+1 prime mover exhaust heat, and wherein said steps a) and b) are achieved through fluid flow between the first heat source, the n prime mover, and the n+1 prime mover, said step b) comprising the steps of:
recovering the n prime mover exhaust heat to an n+1 pre-heater; and
transferring the n prime mover exhaust heat to the n+1 prime mover through an n+1 heat exchanger;

c) providing cryogenic liquid working fluid to feed the fluid flow, wherein the cryogenic liquid working fluid provides cryogenic compression of working fluid to each of the prime movers.
