    In my DC electronics class I decided to figure the cost of chaging my 9930 for one hour using a charger from a my previous 9650. The charger is a Blackberry brand with output of 5 volt/700 mA and my cost of electricty is .12 kWh

    .12 x .0035 equels $.00042 cents per hour charge hour. Not much! Now if we take the reported world total of 75 million Blackberry users you would have 75,000,000 x .00042 which would equal $31,500.00 cost per hour to charge the worlds crackberry addiction.

    For those of you familar with wind turbines, the large commercial turbines with an output of 1.5 Mwh would need to operate at rated capacity for 15 minutes to feed the worlds supply of BB addiction.

    Kinda interesting and please forgive me for errors in math but I'm pretty sure this is correct.

    Small error would be that this would be the most possible.
    9930 and 9900 use the most possible amount of electricity. (Along with 9850 and 9860).

    Oh. And you didn't add PlayBooks. :P
    Maybe look at the electricity pulled for the old 8703e's and see if you can average them or get a mean by the type of OS's.
    For example, OS4 OS5 and 6, OS7.
    There are a few statistics of how many people are on them.

    Let me clarify...begining DC electronics class...I'm not this smart

    Smart enough to consider it. You can refine it as you learn.

    Feasibility of nano-generators under the keycaps?

    The voltage rating is the voltage supplied however the current draw may not be 700 mA. I am not overly experienced in charging methodology but the way you described it it is worst case scenario. That assumes that when you plug in the charger the battery pulls full current.

    What would thos nano generators be using to produce juice? I suppose heat could be used in the same sense that a thermocouple operates but your efficiency and minuscule amounts of electricity produced would be negligible.
