Underwater Turbines Set To Generate Record Power

Here’s a preview of the future. Twin underwater turbines are set to generate 1.2 megawatts of electricity off the coast of Northern Ireland by year’s end. New Scientist reports how the world’s largest tidal power project will use underwater turbines that look and work like wind power turbines, with blades up to 60 feet wide. Tidal currents will rotate the rotors at 10 to 20 revolutions per minute — a speed that Marine Current Turbines of the UK claims is too slow to affect marine life. The turbines will drive a gearbox that will drive an electric generator. The resulting electricity will be transmitted to the shore via an underwater cable. Eventually, MCT intends to build farms of turbines consisting of 10 to 20 pairs each. . . This is intriguing, probably necessary, and will doubtless lead to some kind of negative environmental issue(s). Let’s hope the Brits monitor the impacts of what sounds like a promising, hopefully sustainable, technology &mdash one desperately needed on our tough road to a new energy economy. JULIA WHITTY
