TALLEST TOWER CATCHES SUNRAYS
More than 1,200 mirrors surrounding a 165-metre tower in southernSpain have begun harnessing solar power. Unlike photovoltaic cells,the mirrors focus solar radiations onto a receiver at the top of thetower to boil water into steam. This drives a turbine and generates 20megawatts, sufficient to supply 10,000 homes. Developer AbengoaSolar said this is the largest solar-tower power plant in the world; itwill avert 12,000 tonnes of greenhouse gas emissions that a fossilfuel-fired power plant would have produced. |
