Things you don't need: Power up your mobile with your Wellies

Just come across Ecoterra.com website - the strange love child of environmentalism, tech and the fashion world. Lots of clever bits of recycling, tech and clothing for things you dont really need.

A great example is the wellies that can power a mobile (it was either this or the dancepants that can power an mp3 player!).

The sole of each boot contains thermoelectric modules that convert temperature differences—say the warmth of your foot versus the cold of the ground—into electric voltage. When a sizable charge accumulates, simply plug in your phone into the power output at the top of the wellies.

I do not really think they get the consumption issue...
