Wish I had somewhere to take a course. I have always been far ahead of everyone in my thinking and as such, end up being laughed at an ridiculed about new things. It also means doing things the hard way most of the time.
Last year I built a solar colector out of ABS pipe. I have gotten 140 deg. out of it with no trouble and know I can get it a few deg. warmer. I would use that as a preheat, reducing the energy required to take it to the boiling point of methanol. You metioned heating both the diesel and glycerine. I assume you do this after settling. Do you stir it as well during the distilling?
