This portable wind turbine is a very British solution to off-grid power

Although solar panels are now lighter and more efficient than ever, the makers of this turbine are based in Britain – and it’s an optimistic engineer indeed who sits spannering solar panels while the wintry maelstrom batters the workshop windows. Texenergy reckons that in wind speeds of 15mph upwards the £85 Infinite Air will output 5V at 1.5A to 2A. That’s enough to juice up your phone, your GoPro, or even an iPad. Not bad for something that weighs under 500g and breaks down into parts small enough to fit in your pocket. Electric car charging? That might have to wait for Infinite Air 2. (Tagline: This Time It’s More Infinite.)

About

Fraser used to wear a Psion Series 3 palmtop in a shoulder holster. Perhaps he still does.Either way, his lifelong mission - including fourteen years for Stuff - has been to see whether the consumer electronics industry can ever replicate that kind of cyborgian joy.So far: nope. Despite a plan to combine a action camera and Olympus Eye-Trek goggles to become Man Who Sees The Vision Of A Man Three Inches Taller Than Himself.He also likes mountain bikes, motorbikes, cars, helicopters. Still thinks virtual surround is witchcraft. Dislikes jetskis, despite never having been on one.
