Abstract : In the patent application micro electrochemical cells which use an intimate mixture of active and passive metals are reacted with seawater for producing heat and hydrogen gas for use as a heat source, energy source, or buoyancy generator for use in remote areas. The present invention may be used for replacing lost body heat for undersea divers or combat troops. It is shown that a mixture of finely divided iron and magnesium powders which have been ground into a composite material in a ball mill, or the like, can be reacted rapidly with seawater to serve as a heat source.
