Franco’s stove

Nice Works!

I only have a similar one,but not completely same(no pot stand necessary).

Schematic drawing

Very Interesting Franco, but help us out here. What is the fuel used? How does the candle fit into the picture and the wick? And how do you use the piece of coat hanger in the stove? Is it a pot support (seems to be) that raises the pot for some reason? Sorry about being so dense but I can't tell much from the pictures.

I have deliberately gone away from the soda cans because they don't last more than a few burns if the flame hits the walls. Amazing design though !!!

The fuel is alcohol (mentholated spirit) in this case ( Australian standard) it is 97% Ethanol.

If you look at the top part , the one with fewer holes, you will see a tongue (rim) at the bottom. That creates some pressure on the chamber below (bottom can) and allows (after the alcohol has burnt) to insert a little shelf, in this case a trimmed bottom of a soda can (not shown) to sit a candle on top of it. The candle will just keep the pot simmering. Should work well with a "cozy" on top of the pot in cold weather. ( in my case, I just get the boil, add the ingredients , let the stove extinguish it self, and shove the pot inside a "cozy" ( a bag made out of a reflective sun screen protection for the car).
You could also just add more fuel and keep the boil going. One oz should keep it going for another 8 to 10 minutes.
The coat hanger wire is indeed the pot support you see in the various shots. It is there to allow the top of the can to breathe, the stove does not work without it.
In the second picture you see the four components. Bottom part (fuel reservoir) top (spacer/stand) the bent coat hanger wire (pot support/spacer) and a piece of rolled up soft can skin with the wick , a piece of fiberglass fabric. It can be purchased as "lantern wick" (not the cotton variety…) or from auto accessories section in several stores.
Thanks for you interest.
I am now playing with a shorter top section but so far this one still works better.

I have done some test with the short top version but for the 10g saving it is not worth the bother.
It would be if it performed as well, but it does not. Cutting the top off also makes the can a bit flimsier, the solid feel of the double version is one of the features I really like.
Anyway, here it is…

Thanks,Franco. Much better pictures to show the construction and operation features.Pretty cool little stove idea — two fuel types — one to boil and one to simmer. Well done!

With a different top part (in this case also a different bottom but it does not matter) it can be used for mugs as well. The mug in the picture is 2.5" wide at the bottom.
Similar performance to the pot version.
