Solar Power Energy Information
Has anyone ever considered finger against keypad as a source of kinetic energy for powering electronic devices?

Electronic calculators, dictionaries, encyclopedias etc. use very little power. I would have thought the kinetic energy of typing in information would be more than adequate to recharge or even eliminate batteries. Such a source would have obvious advantages over solar energy. The main disadvantage would perhaps be one of cost. Is there a cheap and simple solution or is the idea ridiculous?
aw4lly, I have an electronic calculator, Sharp EL-556G and have used it daily for several years without ever changing or recharging its batteries. The power supply is 0.0006W. That's about 61 g.mm/sec.

this is a very good idea!
if you could devise a system, possibly electromagnetic, that generates small currents
