Bahrain's world trade center.

Not wanting to be left behind by Saudi Arabia and Dubai, Bahrain has been building an interesting skyscraper. The 50-story complex contains two identical towers that rise over 240 meters in height. The sail-shaped buildings offer a visually striking silhouette and it boasts one very unique feature — Three massive turbines supply clean power to the buildings. This comes as the world becomes alot more committed to a renewable energy source.

At first, the designers wanted to use solar panels but found that the extreme heat conditions of Bahrain made it an unfeasible proposition. The second option was for three 29 meter wind turbines, each supported by a 30-meter bridge spanning between the two towers.

The wing-like towers help to funnel and accelerate the wind velocity between them. Furthermore, the difference in the vertical shape of the towers should help reduce the pressure differences between the bridges, which, when combined with an increased wind speed at the higher levels, should provide an equal velocity amongst the turbines.

The Bahrain World Trade Center has already completed the installation of the three wind turbines, making it the first building in the world to incorporate this sort of technology at this scale.
