Utilizing Ocean Thermal Energy in a Submarine Robot
Posted in Alternative Fuels, Geothermal Power, Batteries, Renewable Energy, Tech Briefs on Wednesday, June 17 2009
A proposed system would exploit the ocean thermal gradient for recharging the batteries in a battery-powered unmanned underwater vehicle (UUV) of a type that has been deployed in large numbers to research global warming. A UUV of this type travels between the ocean surface and depths, measuring temperature and salinity.

Alternative OTEC Scheme for a Submarine Robot
Posted in Alternative Fuels, Geothermal Power, Batteries, Renewable Energy, Tech Briefs on Tuesday, June 16 2009
An alternative system for exploiting the ocean thermal gradient to generate power would be based on the thawing-expansion/freezing-contraction behavior of a wax, or perhaps another suitable phase-change material. The power generated by this system would be used to recharge the batteries in a battery-powered unmanned underwater vehicle.
