[Luis Vega OTEC Summary] – OTEC: Electricity and Desalinated Water Production – Luis A. Vega, Ph.D. (pdf, 29p)
Operation: ocean vertical temperature gradient of 25 degrees Celsius. Continuous production of electricity has been demonstrated in pilot projects, like Hawaii 210 kW plant between 1993-1998. Minimum capital cost: 6$/Watt for a 50 MW plant. If only 10 km offshore, $4.2/Watt and $0.07/kWh is achievable. Hawaii could generate 100% of its electricity needs from OTEC.
