OTEC, Solar and Wind Islands could provide Global Energy
An environmentally friendly technology using temperature differentials in the Tropical Ocean combined with other technologies could enable global Hydrogen distribution, by Mahesh Basantani for Inhabitat.
“Ocean waves are already being used as a source of renewable energy, but could differences in water temperatures in the sea be our next source of green power? A decade old idea to generate renewable electricity for the globe with offshore, floating ‘Energy Islands’ could soon become a reality. The concept – creating artificial islands to collect wind, wave and solar power in the tropics – is based on the work of Jacques-Arsène d’Arsonval, a 19th-century French physicist, who envisioned the idea of using the sea as a giant solar-energy collector.”
While considering this story, I also urge you to read Sam Carana’s articles on the distributed electrical grid, a hydrogen economy and electric cars. He offers compelling arguments to do away with liquid fuels, coal and nuclear power as soon as possible, and to invest in solar, wind, and geothermal power industries that are supplemented by the use of biomass to generate hydrogen (the cleanest of fuels, I would say).
