I did a little more playing around with this. The stove I put together had 8 little Jets or Holes (see previous post). I punched another 8 in between for a total of 16. As expected, the heat output is dramatically increased, but the burn time is much less.
Here's the thing though, for about $4, you can go to Canadian Tire and pick up a 6-pack of 5oz bottles of alcohol-based gas line antifreeze, and make a couple of different sized stoves for nothing. Then, during a power outage you will have the wherewithal to boil water for tea or coffee, or do a little cooking or heating of food. A disclaimer though; The anti-freeze is a bit nasty and poisonous so watch what you're doing...
A slightly safer option might be the bottles of blue cheap fondue fuel from the Dollar Store.
My next step is to make a bigger stove from larger diameter cans...I think my Pyromania is no longer in remission...mooo..ha..ha !!!
