This $18 Roof Device Generates FREE Electricity Forever (Energy Explained)

An $18 bismuth telluride wafer bolted to a wood stove flue produces 14 watts of continuous DC for the entire burn cycle, per the TEG1 12611 6.0 spec sheet. NASA has flown the same Seebeck physics on Voyager since 1977 (312 silicon germanium thermocouples around a plutonium core) and on Curiosity and Perseverance through the MMRTG. Thomas Johann Seebeck published the effect in 1822 and never patented it. 204 years later that same physics ships to Boeing and General Motors but never to residential. The honest payoff is not arbitrage. 14 watts across a 150 day burn season is about 17 kWh, roughly $2.40 at 14 cents per kWh. The real payoff is the blackout: phone, LED lanterns, router, and emergency radio running through a three day ice storm on $80 of metal already on a flue that was going to burn anyway.

The Carnot ceiling caps theoretical efficiency at about 37 percent. Real modules deliver 5 to 8 percent. The cold side, not the hot side, is what almost every YouTube tutorial gets wrong.
