I call BS. No way this can produce any more than a few mW (I guess about 10mW) with this kind of thermal process. I'm guessing there is a battery in there that does the charging and you'd have to have a hot item on it for weeks to charge anything. If you read their own "info" you see they as much as say so. It's a gadget that in theory will work but not in any kind of practical way. Nice how they make you read pages of crap to see the truth.

Another good idea.

People have no idea on how much heat energy is wasted every second. Just tapping a fraction of this energy could make a significant impact on local power grids.

While the price of the device seams a bit high, I am sure that would drop if they were mass produced.

Keep thinking people there are so many things we can do to generate cheap energy.

Just a thought,
