Concert-goers attending the annual five-day Glastonbury music festival in the UK needn't worry about portable power to keep their phones charged, so long as they are willing to shake a tail feather. Vodafone UK will be handing our Power Pocket pants at the event; a pair of fashionable Daisy Dukes fitted with a recharging pocket in the rear.
Developed with disco-digging boffins at the University of Southhampton, the pocket on the pants is made of a special squishy materials (piezoelectret polymers) which collect and holds a charge when the material is crumpled. Therefore, the more you dance (or rodeo-style bull ride) the more power you create for your mobile device. You will have to keep it up though - a full day of festival frivolity amounts to a mere four-hours battery life.
Of course, even the most committed part animals can't dance for five-days straight, so Vodafone will also have a power-collecting sleeping bag available too, which stores power generated by the heat expelled by your body. A full night's sleep can pay back 11-hours of smartphone battery life, according to the experts.
The amount of power you can create and store using these methods is limited, though. People trying to recharge the bigger batteries in tablets will need to think of a way to combine dancing and sleeping bags -- some sort of horizontal mambo, if such a thing exists.
