Power your phone from thin air!
Well almost*, if you’re one of the lucky ones with either an iPhone 6 or Galaxy S6, you too can be the proud owner of a new phone case that allows you to harvest latent energy coming from RF transmissions. Your wifi router and all sorts of wireless transmitters emit enough power to charge your phone up. Now this would seem like something out of a steam punk 50’s sci fi film, but when you consider it only costs around 50p a year to charge your phone, then there’s definitely the possibility that this will help keep your phone topped up.
