Just a stove i made, based on the Pepsi G design, has 8 1mm holes, and runs on 90% alcohol, I'm getting sub 5 min boils (500ml) so its not to bad, trying to tweak the stove some more.
I am however still working on the windscreen. The one i have burns sooty in ambient air, and pretty well with a fan blowing on it. so it might be suitable for the field.
