Since I have been posting a few things on being greener, this is something that can help charge your phone on a beech, in the garden on anywhere else. 

Orange goes green for festival phone-fueling
“Orange today launched a prototype wind-powered charger capable of delivering a constant supply of green juice despite “the unpredictable English climate”. How? The turbine charges a battery, and it’s from that power pack that the phone’s own battery is charged. It is, of course, a variation of one on humanity’s oldest devices, the windmill, though this time kitted out in suitable, sponsor-friendly colour. The windmil weighs a mere 150g - let’s hope it’s capable of being anchored against strong gusts - and is compact enough to be tucked into a rucksack.”
