What the heck is OTEC?
While it may sound like the precursor to yet another huge oil company, nothing could be further from the truth. OTEC stands for Ocean Thermal Energy Conversion, which is generated using the difference between the warm surface water and cold deep water of the ocean. The temperature difference can be used to drive a steam cycle that turns a turbine which in turn produces power. When the warm surface sea water passes through a heat exchanger, it vaporizes at a low boiling point which is then funneled into a turbine generator, producing electricity.
