1. A hydride heat engine comprising:
a) a hot water source;
b) a multi-stage metal hydride compressor comprising:
i) a plurality of metal hydride reservoirs comprising a metal hydride forming compound;
ii) wherein the plurality of metal hydride reservoirs are coupled in series:
c) an electrochemical-expander comprising:
i) an anode;
ii) a cathode;
iii) an ionomer configured between and anode and cathode:
d) a working fluid comprising hydrogen;
e) a heating device that heats water to produce said hot water source, wherein the heating device heats the plurality of metal hydride reservoir to move the working fluid from a first metal hydride reservoir at a first pressure to a second metal hydride reservoir at a second pressure; wherein the second pressure is higher than the first pressure;
wherein the working fluid is passed to the electro-chemical-expander and wherein the hydrogen is transported from the anode to the cathode of the electro-chemical-expander to produce electricity;
wherein the metal hydride reservoirs are cooled by a flow of cold water.
