Made a quick rocket stove with bricks. Put a Peltier cooler on the back and got a fire going. Measured the current, volts, and watts produced from a single Peltier cooler. A cooling fan and aluminum heatsink with a 12V portable battery helped.
Peltier Cooler (also called TEC or Thermo Electric Cooler) - resting against a hot brick
Video of experiment…
The fuel for the fire was just fallen tree branches that I found on the ground. The portable battery was charged up by a solar panel.
The Peltier cooler rested against one of the bricks. The brick got up to 210 degrees F while the aluminum heat sink was about 70 degrees F. At this temperature difference (140F), the Peltier cooler produced:
- 70mW
- 1.05V
- 67mA
The power generated by this Peltier cooler is comparable to the power generated by a small solar panel on a solar landscaping light.
