Where do you see that you get 1 volt when you do that? Also, how much current?
I think a thermoelectric cooler is the same as a thermoelectric generator. When I heat a griddle to 300 degrees and put it on with a heasink on the other side, my multimeter shows as high as 1.7 volts. As both sides heat up the voltage drops.
I'm not sure how to check the current, but probably not much.

Your second link is to a device that requires 3 volts input to produce 5 volts output. 1 volt will not do it.
The lvboost will output 3.3v - 5v, but the input is listed as 0.5v - 5v.

After you fix all that, it will take hours to charge your n900 a few percent.
Agreed it won't do much. My hope is it will give me enough power to check my gps quick if I get lost while I'm out backpacking.
thanks for the reply.
