Thermoelectric wellies that charge your mobile phone using heat from your feet.
Telecom firm Orange, a sponsor of June’s Glastonbury Festival, is promoting its new “Power Wellies”s as a means for festivalgoers to keep their cellphones charged. Created in collaboration with renewable energy experts GotWind, use a unique ‘power generating sole’ that converts heat from your feet into an electrical current. From Popsci:
Users will have to stomp in the Pilton mud for about 12 hours to generate enough electricity to charge a cellphone for one hour, however — so the wellies are more notable for novelty than practicality.
The concept is interesting, however. The boots work by capturing the heat of the wearer’s feet — not kinetic energy, like other walking-power concepts we’ve seen.
