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.

Two new electricity interconnectors planned for UK
LONDON - Ofgem has opened bids to build two electricity interconnectors between the UK and continental Europe.
The energy regulator said this would “bring forward billions of pounds of investment” in the subsea cables, which can import cheaper energy when needed and export surplus power from the UK when it is available.
Developers will be invited to submit bids to build the interconnectors next year. Ofgem will additionally run a pilot scheme for ‘multiple-purpose interconnectors’, which are used to link clusters of offshore wind farms to an interconnector.
This forms part of the UK Government drive to more than double capacity by 2030,…
