We're coming upon festival season again, and you know what that means -- Orange is dragging their solar energy tent to Glastonbury. This year, prepare to charge your mobile phone while checking out the acts at the Jon Peel Stage, courtesy of your new Power Wellies. Developed in partnership with GotWind, the soles of the boots collect heat all day and, using something called the Seebeck effect, this heat is converted into electricity -- electricity that can be used to recharge your phone later that night. As if you needed an excuse to dance in the first place! PR after the break.
