Very young already I liked to build things with my hands,and very often I noticed that the object I realized had a taste of exception. When I begun the MUL (Ultra Light Backpacking in French) I had considered that many practices carried out themselves some some of their accessories. I could simply give you the instructions on how to build a stove with alcohol with two cans as one can find some on the Web , but I believe it’s not quite as interesting to know holding them and the outcomes of the thing.
Some good reasons :
I almost tried all the existing stoves (open jet, stove under pressure, side burner, ion, photon, pepsi can stove....), I always sought for the world’s wonder : a stove which would need no additional support (thus a side burner), effective, not too greedy on fuel, light (when the stove exceeds the weight of certain gas burners I see no interest), sure and resistant.
As one is better helped by himself (ndlr French proverb), I decided to adopt the characteristics which interested me in each already existing stove :
I mixed everything in a bag and the “PRS” was born !
I have tested it and it exceeded my hopes. It is :
And in more it is beautiful !
1st can = Female part the stove
The squares must be quite parallel with the base. They will allow to make a series of holes regularly aligned on it, all around the can.
2nd can = Male part the stove
Here is the simple part of the work. For those which have already made Pepsi Can Stove, they know that imbricating two parts of cans together is quite difficult and often deform the stove (often with escapes). Here is the technique based on the technique of Convex stove (see higher link).
Your stove is finished !
The necessary material
Stick a paper band of 4 cm with dimensions on one of the can and of 2,5 cm on the other.
Cut following the edge of the paper band with the help of a cutter. It is necessary to make several turns with the point of the blade until it penetrates without forcing and avoid crushing it.
Glue a 5mm graph paper band on the female part.
Lay the inside of the female part on a wooden anvil. With the help of a fine needle, punch a series of very fine holes every 0,5 cm and from 1,5 cm of the bottom.
Lay the male part flat (left convex in bottom), and lay the female part top and support gently with the flat of the hand.
Carry out notches every 0,5 cm on the top of the PRS with scissors. Then fold up the strips toward the inside. Flatten them well with a grip.
It’s finished !
The filling of the stove must be made gently to leave time with the 3 small holes to let the liquid fill the inside of the stove.
Larger holes would make easier the thing but would put the pressurization at evil.
This pre-burner is the indispensable condition of the ignition : too little alcohol in the cup and the stove will not burn ; too much alcohol in the cup and combustion will be too strong at the start will waste alcohol which will not be used in an optimal way for the heating of the pan.
•Set the pan on the stove
Make your first tests, fill it operate it, shutdown the light and you will see at which point it is beautiful working stove.
Combustion is done in three phases but is more regular and moderate than a Atlanta Stove.
It not a stove under real high pressure, the dangers of explosion are quasi nonexistent (avoiding too much alcohol in the cup). However it is necessary to comply with some rules and to know some tricks :
The largest danger is to pour fuel whereas the stove is not extinct : burn and explosion could happen in your fuel bottle.
•After thousands tests,i know this stove is secure but you know..... you use this stove at your own risks and dangers...so be careful !
I have one, made by Peyo for me (thanks again, mate ! ;-) ), and they work perfectly. The heat is very good, it heats for a good time, consumes little alcool, is very small, and very efficient ! Great piece of kit to have !
I think the conception is extremely simple, and it works extremely well.
Peyo, That looks like a very well-thought-out system.
I already have a favorite design of my own, which is built out of stronger 3-oz cat food cans, but I’ll need build one of yours and compare the two. Brad
I ave tested one similar stove and it works perfectly.
Very effective for a stove so light and easy to build.
Thanks for sharing with us how you made this stove.
Great to invent and make your own tools and find they work perfectly ! And use as material something that is everywhere around us !
I know the principle of the stove is simple, but still it took designing it and setting to actually making it !
Well done Peyo ! I’ll try and make my own !
Peyo, you are a genius, mate ! i made this stove in half an hour, thanks to your great instructions, and it works perfectly.
thanks, i now have a great little stove, and my scouts have a new activity to try. leon.
Made one of these resently, and in the cold winter of Norway, this almost outperforms the trangia burner with a windshield.
WOW ! Nice design but you weren’t going to give me any credit for it ?
That’s the design I came up with back in the summer of 2005. http://www.uswebfoundry.com/robanna/stove/
I just wonder why he call it a revolution stove ? Theire is more efficient stove that are lighter like on the web site www.voyagerultraleger.com/vente-rechauds.htm.
Peyo Stove, Weight : 15 gr, Time to boild : ± 4 min.
VoyagerUltraLeger.com, Weight : 12,5 gr, Time to boild : ± 3 min.
So VoyagerUltraLeger.com stove is 33% more efficient ! Peyo concept to put the pot directly on the stove is in fact an old concept, and not really efficient as you can see.
What to see the difference ! On the base of 1 liter weight 1 Kg. If 2 persons goes on a trek for 3 days with the VoyagerUltraLeger.com stove, and they consider they need approx. 500 ml (weight 500 gr.) depending on the food they bring. To cook the same food with the Peyo stove, you gone have to bring 33% more fuel (165 gr) that you gone have to carry day after day.
So where is the revolution ???? So use carefully your name (don’t be so ...) AG
Actually, for 3 days, I’d carry my own titanium copy of a sierra wood stove, which amounts 360 grams with batteries allowing 12-24 hours of continuous use , and where the fuel can be found on the road... It also has the same power than the most modern gaz stove, not these lazy alcool stove, and heats a litre of water in less than 4/5 minutes...
For the rest, I remind people that aggressive comments are NOT PUBLISHED, and this one was at the limit.
Hi guys !
My design isn’t new, i know, it’s just the sum of 3 others good design (see 2. ) And then the word ’revolution’ is a big joke ! When i studied others stove, i found their tittles were really megalomaniac... It would be ridiculous to be serious when i build stove in a can LOL
