Ocean Thermal Energy Conversion, un projet qui renaît

Techniquement possible, le Ocean Thermal Energy Conversion était très couteux. Il semble que le projet renaisse de ses cendres :

"Shelved in the early 1970s after realizing the project was technologically possible but economically untenable, Ocean Thermal Energy Conversion, or OTEC, is witnessing a revival. While many gave up on this, such as NREL, now even energy novices like Lockheed Martin are getting back in on it. Currently, the economic potential of oceanic energy conversion, like most renewables, is inversely related to oil prices; as oil prices rise, OTEC becomes viable. OTEC generates power using a heat engine by leveraging the temperature difference between shallow and deep water. The greater the temperature difference the greater the potential, assuming a 20 degree minimum differential."
