Floating ocean turbines proposed
BERKELEY, CALIFORNIA - Wind turbines as a renewable energy source have problems of noise, visual clutter and land use, and one U.S. researcher says moving them offshore is a solution.
Offshore wind farms have been built, but only in shallow water near coasts, and one naval architect wants to go much farther out by placing turbines on floating platforms, a release from the American Institute of Physics said.
Dominique Roddier of Marine Innovation & Technology of Berkeley, Calif., has proposed a platform design dubbed "WindFloat" based on existing gas and oil platform designs.
Roddier and his and colleagues published a feasibility study of the design in the Journal of Renewable and Sustainable Energy, published by the AIP.
Testing of a small scale model in a wave tank showed the platform is stable enough to support a 5-megawatt wind turbine producing enough energy "to support a small town," Roddier said.
A full-size prototype being built in collaboration with electricity company Energia de Portugal "should be in the water by the end of 2012," Roddier says.

IEA: Asia set to use half of world's electricity by 2025
BERLIN - Asia will for the first time use half of the world’s electricity by 2025, even as Africa continues to consume far less than its share of the global population, according to a new forecast released Wednesday by the International Energy Agency.
Much of Asia’s electricity use will be in China, a nation of 1.4 billion people whose share of global consumption will rise from a quarter in 2015 to a third by the middle of this decade, the Paris-based body said.
“China will be consuming more electricity than the European Union, United States and India combined,” said Keisuke Sadamori, the…
