Power Pump cellphone charger ready for glastonbury
U.K. cellular operator Orange is to launch a footpump-powered cellular charger at the annual Glastonbury rock festival.
A compact camping accessory which fits all handsets, the Orange Power Pump measures 154mm by 129mm with a height of 47mm making it no bigger than a packet of Wet Wipes, is lightweight and easy to fit into your rucksack. Encased in sleek black housing, the turbine can generate enough energy to power 5 minutes of call time in the time it takes to inflate a pillow.
That would be about 4 minutes 38 seconds. Get pumping!

Seems like the mechanical energy -> pneumatic energy -> mechanical energy -> electrical energy conversion would be a whole lot less efficient than just going mechanical -> electrical.
