Bahrain World Trade Center generates 675kW of wind energy!

0904-bahrain-wtcI had a beautiful panoramic view from my room in Ramada Hotel Bahrain – sunset over the city, a busy soccer ground and the Twin Towers that I had never heard about! I was intrigued by the three turbines mounted over the bridges connecting the two towers. So I Googled and found the story:

Each of the three turbines hold a capacity of 225kW, totalling to 675kW of wind energy production. These turbines, each measuring 29 m (32 yd) in diameter, face north, which is the direction from which air from the Persian Gulf blows in. The sail-shaped buildings on either side are designed to funnel wind through the gap to provide the maximum amount of wind passing through the turbines. This was confirmed by wind tunnel tests, which showed that the buildings create an ‘S’-shaped flow, ensuring that any wind coming within a 45° angle to either side of the central axis will create a wind stream that remains perpendicular to the turbines. This significantly increases their potential to generate electricity. The wind turbines are expected to provide 11% to 15% of the towers’ total power consumption. This is equivalent to providing the lighting for about 300 homes annually. The three turbines were turned on for the first time on 8 April 2008! The building has won many awards for sustainability.
