Thermoelectric Power Generation On Wood Stove

Here is my Thermoelectric Power Generation scheme using TEC moduals from eBay a small lab hot plate, a heat sink and a small radio I can generate enough power to run. I thought to my self the extreme temp differential in the winter and how my wood stove could be the heat and outside the cold, I jumped to prototype but I ran out of gumption and funding anyways it’s a start and an idea for waste heat power generation.
