Likely, many of you have seen the "no moving parts" refrigerator/coolers that use "Peltier Effect" cooling modules. This uses power to cool one side of the module and heat the other. If you reverse the current flow, they will heat up instead of cool down. What we are doing, in essence, is heating up one side of the module and harvesting the electricity generated at the other, wire end. Most Thermoelectric generator modules use the "Seebeck Effect" a close cousin to Peltier.

Then there are the TEG (ThermoElectricGenerators) sourced from various companies. These are more in line with what I have in mind to test. They can be had in wattages and voltages ranging from a low of 1 Watt to a high of around 20 Watts. They'll also build custom TEGs and sell you separate modules to build it yourself. That's what I am looking into.

Of course, it may not be COST effective. Stay tuned for Part 2 where I will be assembling various configurations and testing the concept. If it works, I'll have a good idea how much all this will cost. The modules I have been looking at are all around 40.00 dollars each. I believe between 2 and 6 modules will be enough. We'll see.
