TEXENERGY INFINITE AIR

Yes, it’s £85, but you won’t be endangering the giant panda while you juice up your tablet. 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 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.
