Can hot and cold ocean currents be harnessed as electricity generators?
Here you go . . . “Ocean Thermal Energy Conversion (OTEC) The water at the surface of the ocean is warmer than the water at deeper depths. This temperature difference can be used by Ocean Thermal Energy Conversion (OTEC) systems to generate electricity. Warm water from the surface and cold water pumped from deeper depths can be utilized by three types of OTEC systems. Open-cycle OTEC uses the seawater itself as the working fluid by boiling it at low pressures. This produces low-pressure steam that passes through a turbine generator to produce electricity. The cold water is used to condense the vapor back to a liquid. Closed-cycle OTEC uses warm surface water to vaporize a low-boiling point working fluid, such as ammonia. The expanding vapor of the working fluid drives a turbine generator to produce electricity. The cold water is used to condense the vapor back to a liquid, which is recycled by the system. Hybrid systems employ both closed-cycle and open-cycle systems. OTEC systems are
