Comparing the 3 top alcohol stoves of different types that I have made.
Left is a fiberglass fill penny stove.
Center is the double wall can stove.
Right is a non-fiberglass fill penny stove.
I used about 3/4 oz of HEET per stove (I spilled some in the right stove, so it was less than the other two)
Fiberglass stove burns for shit - don't waste your time.
The real competition is between the double wall stove and the non fiberglass fill penny stove.
The double wall burned for 10:40. The penny burned for 9:30 - but had less fuel because of my spill.
The penny is smaller, so it requires less space in your pack, but requires an older, copper penny.
I will buy more fuel tomorrow, and build pot stands that are 1/4" above the respective stove. I will attempt to boil 16 oz of cold tap water on each stove under similarly controlled environments to determine which one is faster, more fuel efficient, and longer burning.
