A device is being launched for Glastonbury which uses an air bed foot pump and sheer legwork to charge a mobile phone - promising to help music lovers stay connected on site.
The 'Orange Power Pump' phone charger attaches to a standard foot pump which drives a turbine. This energy is then converted into an electrical current to charge a mobile.
Makers of the device claim you can generate enough energy to make a five minute call in the same time as it would take to inflate a pillow ... luckily for lazier campers 600 more traditional chargers will also be available.
The Orange Power Pump measures 154mm by 129mm with a height of 47mm making it no bigger than a packet of Wet Wipes - or anything else which measures 154mm by 129mm.
Ian Smith of Orange - which developed the device with 'GotWind' - said: "We pride ourselves on creating innovative, fun and ecologically aware products which enhance the Glastonbury experience by allowing festival goers to stay in touch with their friends onsite."
GotWind Managing Director, Dave Pain, added: "GotWind have worked with Orange for a third year to create yet another groundbreaking festival accessory that is sure to become a must have when packing your rucksack."
