Two 50-story glass ‘sails’ rise 780 feet into the sky, creating one of the tallest buildings in the Middle East. This unique architectural marvel is powered by a revolutionary new means for a building this size – wind! It is the world’s first large-scale integration of wind turbines in a skyrise, with three massive turbines – each 95 feet in diameter – supplying clean power to the buildings. Though most turbines stand on vertical poles, these wind turbines spin on horizontal bridges spanning between two towers. The ‘sail-like’ shape of the towers themselves is specially designed to maximise the movement of sea breeze through the turbines. In this episode, we explore the science behind this architectural wonder and discover how engineers pull off this massive, audacious construction project.
