A nearly invisible rooftop wind turbine has won the €500,000 Postcode Lottery Green Challenge 2009. “It’s beyond a dream,” said English entrepreneur Dean Gregory. “This means we can focus solely on bringing this to market.”
The turbine sits horizontally on the roofline, concealed, and creates energy in a variety of wind conditions.
The RidgeBlade is fitted on the ridge line at the top of a building and uses the existing roof area to collect and focus the prevailing wind. This is where the wind is forced to travel over the roof surface, accelerating the airflow though the turbine.
