Witness the Bahrain World Trade Center. Two 50-story glass "sails" rise over 240 meters into the sky along the shores of the Persian (Arabian) Gulf. This unique architectural marvel is powered in part by a revolutionary new means for a building this size - wind. It's the world's first large-scale integration of wind turbines into a skyscraper. Three massive turbines will supply clean power to the buildings. In this hour, we explore the science behind the concept and discover how engineers and construction crews attempt to tackle this audacious project. In an oil-rich region of the world, the team transforms the vision to reality and looks to the future, committed to a renewable energy source of mega proportions.
