New twist on the Bio Lite stove

[COWBOYSURVIVAL]

Can you guys help me understand how this thing is charging a cell phone while it cooks supper?

It is very simple.............I don't have a clue.

BioLite stoves solve this problem by converting a fraction of the fire’s thermal energy into electricity to power our combustion improvement system. Excess electricity is made available to users for charging small electronic devices such as Cell phones and LED lights.

CS, It uses a thermoelectric device. It produces electricity by creating a temperature difference on either side of the device. Obviously, hot on one side, cool on the other. You can take any two pieces of metal and heat one of them. Since the metals respond differently to heat an electric current is formed (assuming you have them connected in a circuit). The greater the temperature difference, the more voltage. It's only a few microvolts per degree of difference. Still, those add up over time. If the stove heats long enough and hot enough then you can produce a small amount of usable current.

Thanks Rick! A thermalcouple....

And now who all plans to get one of these newfangled stoves?

My wood stove goes steady in the winter, it sure would be nice to harness some of that energy and turn it into a bit of electricity. Now, how do you do it on the cheap?

Here's a primer for you.

From the crude drawing they provide, it looks more like a peltier plate, than a thermal couple. Thermal couples generally don't produce much power, just enough to read a difference. Anyways, that is my guess.

"The discovery began in the middle of 1821, where J. T. Seebeck discovered that two not similar metals, if they are connected in 2 different points and those points are held in different temperatures, there will be a micro-voltage developed. This effect is called the "Seebeck effect" as of it's discoverer.

Some years later, a scientist discovered the opposite of the Seebeck effect. He discovered that if someone applies voltage to a thermo-couple, one junction shall be heated and the other shall be cooled. The scientist was called Peltier and the effect called the "Peltier effect". "

They are reverse effects of the same device I believe.

I've already reserved mine (the smaller camp one) and plan on getting the larger one for my earthquake kit.
