Abstract
A system, method apparatus including a bimetallic mechanical pump diaphragm for fluid handling including two walls forming a chamber divided by a snap-acting bimetallic mechanical diaphragm which uses the rapid, concavity inversing, buckling transition of the diaphragm pump fluid as thermal energy in a first fluid is converted to mechanical energy to push a second fluid as the diaphragm moves from a first position to a second position in the chamber. Two sets of inlet and outlet passageways include one way valves to control the flow of the first and second fluids having different temperatures.
