OTEC Bioplume report released

Ocean Thermal Energy Conversion (OTEC) uses large flows of warm surface seawater and cold deep seawater to generate clean electricity. The tropical ocean at a typical OTEC site has two distinct layers: a warm surface layer with low nutrient levels, and a cold deep layer that is nutrient-rich. Introducing deep nutrients into the ocean’s sun-lit upper layers could potentially increase plankton growth or cause algal blooms. Thus, seawater discharged from an OTEC plant should be… Continue reading

OTEC videos

OTECThere are a couple of OTEC videos available on YouTube. The first one is a nice old one about the US Mini-OTEC which was built in 1979, at the end of the film there is a more modern piece added on about how OTEC systems could be built today. The second one was produced by OCEES and is a corporate presentation. The third one is presentation about OTEC for Puerto Rico by Offshore Infrastructure Associates.

Prof. Nathan Lewis, Caltech, on global energy supply
