This video has a comparison between two different soda can stove designs with build video of the improved version. I was looking for one to take on short day trip hikes and landed on a design by Tetkoba.
The version that is built in the video utilizes an inner wall with capillary action, it gets to operation temperature much quicker.
Also the fuel is methyl hydrate or denatured alcohol.
See how to build a stand for the stove here:
