Electricity is generated by a wood-burning stove

After the construction of our bathhouse, there was no electricity in our village for several years. The issue of power grids was solved for a long time and was solved at low cost for each site. I wrote about this at the very beginning, in the first articles of the channel.

For lighting, I used LED flashlights. There is another solution that will be useful to hunters, fishermen, or those who, like Old Believers, live in remote Siberian regions, but enjoy the benefits of civilization (at least electric lighting). It turns out that the production of wood-burning stoves with a built-in thermoelectric generator has been established:

Indigirka stove from Termofor company

Built-in thermoelectric generator with power of 60 W and voltage of 12 V. This is enough to operate 2-3 LED bulbs or charge your phone or laptop (via adapters and adapters). The thermal power of the furnace itself is 4 kW. All is well, but the cost is more 75 thous. rub. - not comfortable for the buyer:

Apparently, this price is due to the cost of the thermoelectric generator itself.

Their work is based on work from the Peltier effect: when one side of the element is heated and the other is cooled, a potential difference appears. The stronger the gradient, the higher the voltage or current. When voltage is applied, the modules can work in reverse: one side cools, the other heats up (the effect is used in car refrigerators).

Although, the cost of the module is low even from a Russian manufacturer, and in China it is even cheaper, the cost of a working system is tens of thousands. Because it may include a control and voltage stabilization unit, fans for cooling the second side, a heat-resistant case.

If desired, you can make a thermoelectric generator yourself. Nothing complicated. Here is a short video with the assembly of such a thermoelectric generator:

In principle, by installing heat-resistant coolers (small-sized industrial) and connecting the structure to the stove, it is possible to illuminate the bathhouse, fisherman's or hunter's house from several Peltier elements. However, the Indigirka oven is designed for such customers. But only the manufacturer needs to work on the cost of the thermoelectric generator itself. Or someone could arrange the production of such plug-in modules at an adequate price for any iron furnace.
