Thanks for the reply. This is my first attempt, so I’m looking for all the constructive criticism I can get. :-)
“(i) the outer can is pretty beat up (as you fellows say) after the firing; aluminum cans don't react well to being in direct flames”
This is my biggest concern. I had run the stove 4 times, three with the pot of water on top of the stove (no pot support). It was collapsing, hence the support in the video. I have some ideas to hopefully address this issue, but I’m still concerned that the aluminum will just burn away. I guess that’s why we test. ;-)
“ii) 'just blow it out' suggests that it may be very susceptible to winds. However, since it clearly needs a pan support of some kind, I'm not sure that matters too much; that can take the form of a windshield.”
It took a couple of tries to blow it out. And, the intent is to keep the opening on the lee side, away from the wind.
“I make it 452W into the pan (2*237*4.2*(5/9)*(212-65)/6*60). Whatever; 6 minutes for a 2-cup boil is respectable.”
Thanks. That was one of the most important questions I had. I’m thinking I can cut some time off that, but at least I know I’m somewhere in the ball park.
“Of course, we'll need to know how much fuel you used; that priming phase could be used constructively, to heat the pan, perhaps?”
Yup, when it’s closer to a real working model I plan to time it that way also.
“You do realize that you are now doomed to spend the rest of your life playing with meths stoves...? ;-)”
Thanks again. :-)
