The Website Vox is reporting that the evolution of wind power over the years has largely been a process of building bigger and bigger blades and perching them atop higher and higher towers.
The turbine being assembled in this video, by MidAmerican Energy, will be the tallest land-based wind turbine ever built in the US, with a hub height (ground to center of blades) of 115.5 meters (379 feet) and a capacity of 2,415 kW. It's not quite up to the level of the best turbines in Europe, but it's mainly meant as experiment.
