Claim:
1. A reservoir temperature differential electrical generator generative of electrical power when positioned partially submerged into a water body, said reservoir temperature differential electrical generator comprising: an impermeable housing; a positively buoyant first end disposed anteriorly atop the housing; a negatively buoyant second end disposed posteriorly endwise upon the housing; an elongate portion disposed between said first and second ends; a first heat exchanger disposed at the first end; a second heat exchanger disposed at the second end; a compression chamber disposed interior to the elongate portion, said compression chamber having a moveable barrier securable between a maximal position and a minimal position to thereby alter the volume of the compression chamber between a maximum volume and a minimum volume respectively; a heat engine; a fluid circuit connecting the first heat exchanger, the second heat exchanger, the compression chamber, and the heat engine, together in fluid communication; a working fluid forcible through the fluid circuit, said working fluid effecting phase change between each of a liquid and gaseous phase along a temperature differential measurable between the first heat exchanger and the second heat exchanger; and a generator disposed in operative communication with the piston rod, said generator adapting mechanical energy into electrical energy; wherein movement of the moveable barrier alters the pressure of the working fluid in the fluid circuit to alter the boiling point of the working fluid responsive to external temperatures, and phase change, effected by the working fluid along a temperature differential measurable between the first and second heat exchangers, effects mechanical action in the heat engine for generation of electrical energy at the generator.
