I've been playing around making soda can alcohol stoves. I'm going to make one with a pair of larger drink cans (the 23oz size -- like so many brands of canned teas these days).

Before I do, I'm wondering if anyone here has already done so, and if there's any reason not to spend my time on this project.

Some concerns I have are:
Is one stove design (such as double-wall versus 'penny' stove) better for larger versions?
It will use more fuel, I assume. Will the extra heat be a benefit over the smaller stoves, or will the greater fuel consumption be a detriment?

I appreciate all opinions and advice. Of course I plan to still make one to try here at home.
