gizmodo.com — A knee brace that generates enough electricity to power 10 cellphones was demonstrated by scientists recently. The brace harvests the energy of a person's knee braking after taking a step, similar to the way hybrid car brakes collect energy to charge their batteries.

I think that is obvious.In this case, "pretty quickly" could mean 1/2 as fast as plugging it in to a regular charger.

I want one that I could put on my arms and provides resistance so that I get strength training throughout the day in addition to charging my misc. items.. Also it should have a "reverse" mode that amplifies my strength while draining my misc electrical devices. (while I am dreaming, lol)

Then you just get tired faster and have to eat more. The energy has to come from somewhere

there are many things my joints due in repeated motions that can generate energy!

Very cool idea and technology though I do get a 'Matrix' vibe off of it. What next a device that harnesses our energy when we sleep...then we're just a step away

Nothing great, given the fact that we have already seen those flashlights which can be powered by our hands' pumping action. Also charging cellphones or powering an LED lamps doesn't require much of an output in Watts.
