Building and putting any sort of offshore wind turbine into place is a fairly impressive bit of engineering, but Denmark's Vestas is truly going the extra mile with its new V164-7.0 MW turbine. Not only does it promise to provide seven megawatts of power but, as you can see above, each of the blades are longer than nine doubler-decker buses, which gives the turbine itself a larger total diameter than the London Eye.
