I think 'energy harvesting' on a micro scale is an important contribution to macro energy issues.

Are you suggesting more "Knee tremblers"?

During the 1970's and on some people have used bicycles and other contraptions to harness electricity. I saw a news report back then about a family who had to ride the stationary bike to power the TV. I thought that was very clever.
I would think that any moving part of the body, including skin, could produce energy that could be harness to run a few small tech appliances and the excess energy could charge the battery pack;D
