For Sale: Three 750 kilowatt sea snakes. Nearly new. Will consider swap for bouncy castle. That could be an ad you see on Craigslist in the near future. The International Herald Tribune reports that the at least some of the ownership of three wave power devices installed by Pelamis Wave Power off the coast of Portugal last year may be put up for sale. This isn't the best news for the wave power industry. The Portugal project was the first commercial scale trial for wave power. The devices took years to develop and the company endured several delays. The three devices went into the water in September 2008, but were then towed back to shore due to technical difficulties. The difficulties were largely repaired, but then the credit crisis hit. Babcock & Brown, a member of the joint venture that owns the devices, says it is looking at selling several of its assets. This includes the interest in Pelamis. Babcock said it won't put more money into it. There is no timetable for returning the devices to sea, Pelamis said. The wave power industry, though, is used to setbacks. Finavera Renewables had its trial buoy sink in the first few weeks of a trial off the coast of Oregon. Several companies have had difficulty getting financing. But the enormous potential for power is too great to ignore, say advocates. In an ironic side note, we asked Carcas last month how the Portugal trial was going. "We're still in the work up phase. We only got things going September. But the results are in line with what we were expecting," he said.
