This thing is pretty cool, you can take it with you on a camping trip or go fishing and in any situation be able to charge a mobile device, whether it's a phone or tablet.
Unlike Power Bank, this generator has no restrictions and can work continuously. As a heat source, you can use not only a candle, but also chips of firewood or paper.

DIY heat generator manufacturing
The first thing to do is find a tin can. Cut off the bottom and drill multiple small holes along the entire lateral surface. Large openings should not be done, otherwise in windy weather the fire will go out from a strong wind.
Then, with scissors for metal, we cut out a window for a candle at the bottom of the can.
Be sure to clean the sharp edges with a file or file after the cuts.
Here is the heart of the heat generator - the Peltier element. It will generate current when the temperature difference of its surfaces. That is, we will heat one side with a candle, and the other we will cool with a radiator from the computer.
To ensure reliable heat transfer to the Peltier element, we apply heat-conducting ointment on its sides.
We smear one side with a thin layer.
We attach to the bank.
Smear the second side
So that during the period of operation the wires do not float on a hot jar, it is necessary to wear fiberglass sections of the tube - cambric.
And already on top we install a radiator from the computer processor. There will be no cooler from the top, everything will cool naturally. Especially in nature, a little breeze will do its job.
The Peltier element does not produce a large voltage, about a volt, but on the other hand, the current strength is sufficient for our purposes. Therefore, in order to exchange the values for the ones we need, we will use a boost converter, which will increase and stabilize the output voltage to 5 V.
Solder the output of the element to the input of the converter.
At the output of the converter there is already a USB socket for connection, so you do not need to solder anything else.
Heat Generator Test
We light a candle.
We insert into our reactor)).
We are trying to charge a mobile phone. After a few seconds, the voltage reached a level.
And the charging of the phone has begun.
A thermal power plant does an excellent job of generating electricity.
If desired, you can add a fan by connecting it to the output of the converter. Five volts is enough to spin and a twelve volt cooler.
For reliability, a jar with a radiator can be fastened together with a thin wire or with thin long bolts, having previously drilled holes there and there.
Here we often turn off the lights at home. And when this happens, I take out a heat generator.He gives electricity and light from a candle, killing two birds with one stone. Well, if there is not enough light, you can also connect a mini LED lamp to USB. The good news is that this device is always ready for use, and therefore there can be no unexpected troubles.
