Abstract
A Stirling engine includes a piston and a displacer that move in phased reciprocating motion within one or more cylinders. A working fluid is contained within the one or more cylinders, and a position of the displacer causes the working fluid to be in contact with either a hot heat exchanger or a cold heat exchanger. A volume of the working fluid governed by a position of the piston is referred to as a compression space. The piston, the displacer and the working fluid operate in a thermodynamic cycle that generates acoustic wave power. An acoustic pump is driven by the acoustic wave power.
