Orange Power Wellies

The 2010 Glastonbury Festival of Contemporary Performing Arts is scheduled to take place in June 23-28, and these boots are made for walking during it, apparently.
According to a Press Release, these are the Orange Power Wellies, and they were created in collaboration with renewable energy experts GotWind for “a unique power generating sole” that converts heat from the feet into electricity.
Say what now? You mean that all that sweaty feet can be used to power something like a mobile device? Apparently so. In fact, about 12 hours of stomping around can give enough of a charge a mobile phone for about an hour. You want more power, then you had better get your feet moving. Seriously, the hotter your feet get, the more power you can make.
This apparently uses the “Seebeck” effect with thermoelectric modules constructed of P-type and n-type semiconductor materials to make a thermocouple. “When the heat from the foot is applied on the top side of the ceramic wafer and cold is applied on the opposite side, from the cold of the ground, electricity is generated.”
It doesn’t look like these will be available to buy, but it looks like the Orange Chill n Charge area will be at the Glastonbury festival. I guess you can check it out there.
