Think Geek has some great innovative gadgets, that also help in your fight of saving the environment. Take for instance, the PowerPot Thermoelectric Generator, which is so handy, that we are surprised no one else thought of it before.
The PowerPot Thermoelectric Generator is a must have in your emergency kit, as it has been designed to convert any heat source directly into power that charges your USB handheld device.
All you have to do is to add water to the PowerPot and place it over a heat source and plug in the flame-resistant cord. You can heat the pot over a stove, campfire, wood stove, propane/butane heat source etc and backpackers will love it.
It charges a cell phone in 1-2 hours (just as fast as a standard outlet) and is available for $149.99.
