Scotland Building Wave Power Farms

eldavojohn writes "Scottish engineers are taking advantage of the huge ocean coast that Scotland enjoys by building a 'wave farm' to harvest electricity from the ocean's powerful waves. These big red tubes have been named the Pelamis System after a sea snake. Max Carcas, the business developer for the firm, says it is 'a bit like a ship at anchor or a flag on a flagpole, it self orientates into the waves ... Waves then travel down the length of the machine and in doing so each of the sections, each of these train carriages, moves up and down and side to side.' These snake-like movements push hydraulic fluid through generators to produce electricity."

I wonder how it compares?

Ocean Power is currently installing their Utility-sized bouys off the Oregon Coast, with the first 14 being a 2MW power plant for the city of Reedsport (providing about a quarter of the needed electricity for that resort community). The BBC article doesn't say what the expected output of the Scottish plant, using different technology, would be. Anybody know how the power output compares?

More British Sea Power (ho ho)

There are plans afoot to harness the ridiculously powerful tides of Strangford Lough in Northern Ireland, and build a turbine of similar generating power to this contraption. The tide there sometimes moves as fast as you can jog.Here's a BBC report on it.
