Floating ocean turbines proposed
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.

"It's freakishly cold": Deep freeze slams American energy sector
CALGARY - A deep freeze is roiling electricity markets in more than a dozen U.S. states, leading to record-setting prices for electricity and natural gas, knocking oil production off line and shutting down some of North America’s largest refineries.
“It’s freakishly cold,” said Eric Fell, a senior natural gas analyst with Wood Mackenzie in Houston, where record cold temperatures and snow have blanketed the city, caused rolling power outages, shut down refineries and sent both natural gas and electricity prices soaring.
