Do you mind expanding on your experimentation?
For an off-grid cabin in the Yukon I've always though about having a ton of TECs sitting on or very near the wood stove (which burns for 8+ months a year), with some piping and coolant running outside to a radiator (where it's -20C to -45C for 5+ months).
I expect a least a few hundred degrees C of temperature difference, and I wonder about charging the batteries to augment the solar.
- danboarder 5y agoAs I recall the voltage was similar to a AA battery (per module) with a 30+ degree difference on each side of the cell, so a lot of modules could be assembled in an array to generate useful power. A lot of small boat/RV refrigerators use these for their direct thermal effect (one side will get ice cold when powered). My experiment was a smaller scale parabolic solar trough design with a line of modules along the focus point since I needed to heat water anyway to regulate temperatures in an aquaponics system (fish farm). Side note, I've seen successful systems out there that use Stirling engines to power a generator from the concentrated solar heat.
