Just looking at how he made the stove, I wonder if some of the holes were clogged up with aluminum dust, thereby blocking oxygen flow. I would take a few minutes to clean out each of those holes in the stove before lighting. It might speed the process due to better oxygen flow.I'm wondering... once lit, could you transfer the flame to the outside holes immediately or do you have to wait the full two minutes for it to occur naturally? Ideally, the alcohol should create fumes almost immediately and they should be flammable. With that in mind, why light the center? Couldn't you light the outside holes first? Any thoughts on why this will or won't work? Finally... how do you put it out? If I put in 2 ounces but only use one to heat water. I'd like to save the remaining alcohol for a future use. I'm wondering if I could just take an old vegetable can and cover it to kill the oxygen and smother the flames. And... that can might be a good outer cover to store the stove in so it doesn't get damaged in your BOB. Also... once lit, is it dangerous to add alcohol to the center area or is that a flame risk? I'd rather not put it out, add fuel, then wait two minutes to start using it again.
