That was the intent behind listing m2epower.com
That is how it generates power.
We have 4 ways to do it.
1) Glowpaint sprayed on solar panels - litroenergy
2) Getting energy from when we press down on the keys, i.e. - piezoelectric
3) motion to energy - m2epower
4) nokias ambient EM wave collection

There are actually a couple more ways but I didn't feel like going to find out all the details about them.

Regarding glopaint.com, when the new "glows for 20 years paint" is finished being tested by the government and has recieved approval for widespread use I think Nokia should start painting their keyboard characters with it. That would save the light being used on the keyboard.
Always glowing keybaord characters.
I don't see why they don't use regular glopaint when painting their keyboard characters right now.
