Charge your phone with your arse, thanks to Vodafone
As festival season gets underway, this could be great for the kind of terrific berk who likes to pretend to be homeless for a weekend while watching gaspingly awful indie bands.
This technology - the kind that appears every summer with a festival slant - is being developed in partnership with the Electronics and Computer Science Department at the University of Southampton.
Trials have shown that, after a full day of walking and dancing, the harvesting material in the Power Shorts will have enough juice to equate to a phone that has been charging for over four hours.
As well as that, heat generated during an eight-hour sleep in the Recharge Sleeping Bag could add 11 hours onto a smartphone’s battery life.
"We are exploring two specific technologiesto charge the Power Pocket: thermoelectrics and kinetic energy harvesting," explained Stephen Beeby, Professor of Electronic Systems at the University of Southampton. "Both represent cutting edge research around smart fabrics and we are looking to integrate these into consumer products, in this case, a sleeping bag and a pair of denim shorts."
Of course, for those of us who don't go to festivals, we'll have to endure countless, insipid festival tweets and Facebook updates, cooing at The Vaccines and shouting 'BOOOOOLLLOOOOOOCKS" in the night.
