A BRITISH company has won a 500,000 euro ($A850,000) environmental prize for developing a slender residential wind turbine that lies flat at the top of slanted roofs. Power Collective representative Dean Gregory said his company would use the money from the Netherlands Green Challenge to bring the product to market. The "RidgeBlade" design harnesses wind deflected toward rooftops to generate power. Unlike existing rooftop turbines, it doesn't change a house's shape.
