In the reference room of the library today they had 3 new books that just came in on Energy and hadn't even been shelved yet. Hoping for some info on micro-hydro, I looked at them. I came across this:
A micro-hydro plant in your shoes!
Apparently someone has studied the motion of the feet in walking and is working on a 2 part micro-hydro plant in shoes. The idea is that there would be a cushion of water in the heel and one in the toe, connected by a channel. The act of walking moves the water enough that it can generate enough power for a cell phone, iPod, or whatever.
I think that I read someone is working on a backpack for emergency crews that generates enough power to provide light by using the shift in body with every step. If insoles work, why not water filled belts?
