nPower PEG (Personal Energy Generator)

Used to charge handheld electronics, the nPower® PEG is a small, lightweight device that allows you to create renewable energy while you walk or run.

Just place the PEG in your backpack, briefcase, or handbag and walk. As you move, the PEG harvests the kinetic energy that you're already generating and converts it into usable power for recharging your cell phone, MP3, or other handheld device.

On average, consumers lose battery power in their cell phones once per week. When the PEG is carried during your daily activities, the PEG continually tops off its internal power storage so that you'll never be without power.

Thermoelectric Boots

"European Telco Orange is showing off an interesting phone charging prototype – a set of Wellington Boots with a ‘power generating sole’ that converts heat from your feet into electrical power to charge your battery-powered handhelds. You'll need to walk for twelve hours in your “Orange Power Wellies” to get an hour of battery life but we still think it's remarkable that such significant amounts of energy can be harvested from normal human activity. In order to decrease the length of time you need to charge your phone, try dancing or running, because the hotter your feet get, the more energy you produce.

The “Orange Power Wellies” were created in collaboration with renewable energy experts GotWind, with the vision of keeping Glastonbury Festival goers connected with their friends during the event." -via GIZMAG
