I wanted to design a cooking system that was…..
@ cheep
@ burn any liquid
@ UL
@ worked in the cold
@ Recapture un burned fuel
@DIY
@ had a heat sink for speed and efficiency
This is what I came up with.

Specifications
Weight: 3.5 oz
Boil test: 7 min 2 cups of ice water 45 degree ambient air temp
Boil time: 21 minutes with 1 oz denatured alcohol
Warning: This alcohol stove is actually loud, my girlfriend commented that it sounded like out MSR reactor.
Construction materials
2 large Heineken keg cans (1 for the pot and 1 for pot base/ heat sink wind screen)
1 large fosters (heat sink)
2 small Heineken keg cans (combined for pot stand/ stove wind screen)
1 Gillette travel sized shaving cream canister
1 paperclip
JB weld
A few pictures so you can see how the heat sink was assembled.
I should have taken pictures of all the pieces before they were assembled. The first thing I did was make the heat sink by cutting a fosters can right above the gold ring around the bottom. Then I used a dermal to cut out the bottom and cut slits around the remaining of the bottom of the can. I used a little JB weld before pressing it on to the bottom of the Keg can to aid in heat transfer between the heat sinks and the pot.

Then I made the base for the pot by cutting another large keg can right above the bottom budge. Then I used a dermal to cut out the center but I left the almost vertical part in the center for strength. If you do this part correctly when you press it on to the pot it should slide over the heat sink and only contact the pot at the base of the bulge. I used some JB weld here also to aid in heat transfer and hold the base of the pot in place as it has to support the weight of the pot when full of water and protect the heat since in my pack. For these first two steps I used a full room temp un opened keg can. So I could put more pressure on it when pressing the fitting together and had it at room temp so there would be no condensation on the can to keep the JB weld strong.

After the JB weld dried over night I chilled the beer and then used a side cutting can opener to put the top off. Then I formed the heat sink by bending each blade of aluminum down and twisting it with needle nosed pliers.
Then I made the stove in Wise Old Owls thread here

But I didn’t add any wick or anything but I did add a paperclip for a handle.
Then I made the wind screen by cutting the top off of a small keg can about half way between the top and the first budge. If you cut it off higher it will go too far in to the heat sinks. I then used the handle of a hammer to smash the inside bottom of the can flat to hold the stove and insulate it from the ground. Then I used bulges from a second can all cut up to make a wider base for the can and a wider holder for the pot just to make it more stable. It worked well. Then I used the dermal to cut a bunch of hole in the stand/wind screen. I then cut another row of holes around the very bottom for real cold weather priming but I don’t know if you even need them but it does help to warm up the stove fast.
Here is a picture in action. You can actually see the heat sinks glowing.
