Huge, hurricane-resistant wind turbines could be coming to an ocean near you

When it comes to big wind power projects, we’re starting to throw caution to — well, the wind. Sandia National Laboratories — with funding from the U.S. Department of Energy — is setting out to create towering offshore wind turbines with blades 650 feet long. That’s two and a half times the length of any that exist today, according to Sandia’s announcement . For a sense of scale, 650 feet is roughly the length of two American football fields, seven blue whales, or $3,250 in $5 Footlongs. Thankfully, these titanic turbines are going to be a lot sturdier than your average wimpy lettuce sub — and they’ll provide us with a lot more energy, too. From Motherboard : Most conventional wind turbine blades measure over 100 feet, and can generate 1 or 2 megawatts of power. Sandia thinks that by expanding the blade size dramatically, it can increase the amount of energy a windmill can...
