Open up your wallet and see the number of notes within – while most of us can just think about preserving and growing that amount, many others would prefer to indulge in their whims and fancies when the going is good. Emmanuel James thinks otherwise though as this Sierra Leonean student from the Makeni Polytechnic Institution came up with a device that juices up cellphones without the need for electricity. No, that doesn’t mean he stays under a storm as a conduit for the lightning to a gadget, but he used local bank notes (Leones) in tandem with a couple of component circuits in between the two circuit’s poles terminal to produce electricity. Don’t think this will be commercialized anytime soon as battery companies have the most to lose when that happens.
