Well,
I built two pepsi can stoves. One is a small one 1" high, I built it to boil up a cup of water for some coffee or something. And a larger 2" high one for doing some serious cooking.
I wanted a solid wall on the inside instead of the flimsy pieced together wall made from the side of a can. I used two pepsi cans for the top and bottom obviously, and then used a Starbucks espresso can to make the inner wall. I left the bottom on the starbucks can, and drilled three holes in the bottom of the can, for the vent holes.
The big can stove will bring 4 cups of water to a rolling boil in 10 min,or 2 cups in 6 min and maintain the rolling boil for 20 min before it finally runs out of fuel on 1.5oz of denatured alcohol.
I used 12 1/16" flame ports around the top edge of the stove.
Then I polished the stoves with a brillo-pad to make them all shiny.
These things are awesome. Why spend $79 bucks on a heavy jetboil when you can build a pepsi stove for about 4 bucks in pepsi and starbucks coffee.
Im sticking with the pepsi-can stoves. I wished I had known about these things 10 years ago.
