1. A Stirling engine comprising:
a piston and a displacer that move in phased reciprocating motion within one or more cylinders; a working fluid contained within said one or more cylinders, wherein a position of said displacer causes said working fluid to be in contact with either a hot heat exchanger or a cold heat exchanger, and wherein a volume of said working fluid governed by a position of said piston is referred to as a compression space; said piston, said displacer and said working fluid operating in a thermodynamic cycle comprising a first phase wherein said piston compresses said working fluid in said compression space, a second phase wherein said working fluid is displaced from said cold heat exchanger to said hot heat exchanger and a pressure of said working fluid increases, a third phase wherein a volume of said compression space increases as heat is drawn in from outside said engine, and a fourth phase wherein said working fluid is transferred from said hot heat exchanger to said cold heat exchanger, the thermodynamic cycle generating acoustic wave power; and an acoustic pump driven by said acoustic wave power. |
