Jim I sure took a huge interest in your thoughts and I cannot reproduce your claim this morning. Using measured cups of water and well constructed homemade stove and several tests later - I cannot find a difference. Now please understand - this is not an attack on you, had it worked out differently I would have tossed my Heet in the gas tanks and burned it off, Which I am probably going to do anyway now that I have a huge can of Ethanol. I do like the fact that the can is labeled clean burning for stoves on boats.
1 cup of water with 20 Ml of Ethanol vs 20 Ml of Methanol doesn't make a slightest difference in getting the water to boil. 4 minutes 30 seconds 210 degrees.
Does it burn hotter? It might, but it has to gassify, and burn the air too. I am sure I can construct a proof to see which burns hotter - but for now, it's the same amount of fluid. Same amount of time.
Side note after three tests in the kitchen with Heet, I have a sore throat - Gives new meaning to "Don't try this at home."
Folks another note - be very careful about picking up hot objects - watch for melting pot stands, Aluminum will melt etc. Some of the stuff you see in you tube is disaster waiting to happen.
