MIT Technology Review: The engineers responsible for maintaining the hardware at the Burbo Bank wind farm, off the northwest coast of England, will need a head for heights. Standing 195 meters tall, these are the tallest wind turbines in commercial use on the planet.

Each one is fitted with three 80-meter-long blades, allowing it to crank out eight megawatts of power—for a grand total of 258 megawatts from the entire installation, which went live this week. According to the Danish firm DONG Energy, which led the project, a single revolution of the blades on one turbine can power a home for 29 hours.
