...turn a wheel as the water ebbs. But the dream has always been to tap the power of the ocean itself - to harness the force of tides mighty enough to erode and shift entire coastlines. And so later this year a small South Wales company called Tidal Hydraulic Generators (THG) plans to lower a steel frame supporting five 6-m diameter turbines to the floor of the Severn Estuary. The tubes will translate the power of the tide as it ebbs and flows into one megawatt of electricity, enough to power about 500 homes. The project will be a test...
...energy here is absolutely astronomical - Richard Ayre, managing director, THG...
...could still be used to desalinate sea water and pump it ashore - a self-propelled water purifier. Babtie has already sent a team of engineers to the Middle East to discuss the possibilities of setting up tide-driven desalination plants. Ayre is expecting that once the technology is proven, THG could be supervising the construction of rigs to generate "many thousands of megawatts." But no one expects the new system to be entirely smooth sailing. As any boatsman knows, the moment something goes into seawater it starts corroding, and soon becomes covered in barnacles and weed. The THG engineers...
