It's a fun process to create something and then *improve it*.

I had this theory that it could work with slightly less than 15ml because last time it had a rolling boil for over a minute. So I tried a ml or two less and it didn't boil. Strange. It only reached 92c. Could it be because theres a small gap where I kept the thermometer the whole time? Or is it more because of how the fuel heats and boils in the stove?
I'd love to make this stove & screen more efficient. That's the whole point of the cone concept isn't it that it's more efficient than a 'plain' windscreen.

Anything out there achieve boil on only 13ml?

You might also consider the boil temps based on your altitude also. The attached chart will give you a better idea.

Thanks ggarris that does help. My thermometer was never really showing 100c in my boils .... but it was showing 98.5 / 99 c. We are about 1000ft above sea level here.

Yes, a type of cone set-up. It has a jacket instead of cone to help with it's efficiency.
