Interesting. Using a fan to accelerate combustion was an intelligent idea.

An improved version would not be assembled with pop rivets. When pop rivets are
used in thin material they tend to loosen over time. Otherwise a very innovative
approach.

Give Wayne 2 weeks with a Bio-Lite and he would likely have an Elecraft upgrade --
AKA MythBusters style. :-)

What are thermocouples, peltier elements?

Love it - the KX3/W Wood-Powered all-band radio! Alas, with only 2W (and at
5V) out of the thermocouple, I think that idea will have to wait for
Bio-Lite Version 2.

Re: Bio-Lite Stove & Charger

You do not get five volts from a thermocouple. Usually about 0.1 volts depending on the type and temperature but you can connect many in series to make a thermopile. If you are creative you can home brew your own stove, blower and thermopile and be the first with DXCCWB (wood burning).

Re: Bio-Lite Stove & Charger

In reply to this post by Holger Schurig-2

Actually, the entire junction is immersed in the temperature to be measured with the thermocouple. The other ends are joined in a controlled temperature area and the current is measured to find the unknown temperature. If two thermocouples are connected in series the voltage available is doubled, tripled with three, etc. so you can accumulate any voltage you want by stacking the junctions in series. The hotter the junction, the more voltage generated, so the heat can produce a small amount of electricity for charging a cell phone or similar low demand device. Very handy when you have no electricity in your house and need to boil your rice anyway. All you need is a hand full of sticks and the stove. The thermopile also generates the electricity for the blower.

I was being careless calling it a "thermocouple" - it's actually a
"thermopile" using the Seebeck Effect. Mechanically dissimilar metals are
placed in contact with each other while one is heated and the other is not.
The temperature difference produces an electric current to flow.

This old technician will stop there at let the physicists in the reflector
here go into more detail ;-)

I did a little digging to reassure my memory of the Soviet device and found
photos on line! (Is the internet the greatest library since Alexander or
what?)

Here are photos:

l

They generated enough power run a tube-type radio, providing power for
filaments and high voltage for the plate circuits. From the description, the
radio was a low-power-consumption portable using 1.5V on the filaments and
90V on the plates, but that is still impressive for a small oil lamp!

The above web site has a lot of fascinating information about
"Thermo-Electric Generators".
