First thing that came up when I just checked google https://www.clawhammersupply.com/bl...207958-methanol-will-moonshine-make-you-blind Unimpressed with that flat at stove. It's a container with holes in the side, and if you read the specs it says it'll burn up to 70% iso, you have to add water to get it there if yours is purer. So it'll use iso if you dilute it to to the calorie density of ethanol or less?! Pretty sure that's true for any meths stove. I tried some designs that were somewhat more inventive and all failed. Holy grail innit.
