The outer mechanics of this kinetic to electrical energy device are pretty simple – pump it with your foot and make power, you know, just like the old pedal-power TV but actually effective.
The Weza has an internal, rechargeable, 12V, 7Ah lead-acid gel battery (sounds nasty) that’s capable of jump-starting just about any vehicle you could choose as well as power a whole host of smaller devices.
Your foot power supplies somewhere in the region of 25-40W, depending upon how much of a beefcake you are, but don’t worry if you get a cramp, it can also be charged from the mains or a DC source including power generated through wind and solar action.
Although its $269 price may seem fairly prohibitive, it will of course pay off in the long run but, more to the point, the Weza looks like a very real and viable solution for renewable power in the developing world. Now, you just can’t argue with that.
