Regarding comparing the stoves... yes, I originally simply pointed the holes inward because I use a narrow pot. Like the post above stated, this doesn't work. The flames are too confined, and they cannot sufficiently heat the fuel (the heat has a longer path to reach the fuel). This is what inspired me to add the wires. The same stove without the wire takes nearly 9 minutes to heat 2 cups of water... this stove can do it in under 5. Prime time with several drops of fuel is ~20s.

It's really simple to add the wires to the soda can design, which aren't really coils, but more of a "C" shape that I bend to fit. I plan to put a how-to online soon, but if you have ever made a can stove, you can easily make this.

This stove isn't any better than most stoves in terms of boil time, but it's the first alcohol stove I've manage to make with short boil times for NARROW pots.
