In the future, we will look at these 885-foot-wide structures in the middle of the ocean and we won't even blink. But, right now, I'm having a hard time imagining them spinning en masse at 20 revolutions per minute.
It's the new Aerogenerator X Vertical Axis Wind Turbine, which will be completed by 2014. Instead of using a traditional vertical structure, this wind turbine will rotate horizontally. Its design will enable it to generate twice the power of previous designs, according to the manufacturer. That's 10 megawatts per hour. The most powerful—and largest turbine in the planet at 413-foot high—now generates a bit over seven megawatts.
Only the 10MW Horizontal Axis Wind Turbine will be able to match its power, at the cost of raising an impressive 606 feet over the surface of the sea. That would be really fun to repair. [Windpower via Dezeen]
