i looked into this years ago to make organic methanol. the problem is you need a licence for a still from hmrc. i did try to get one. but as paul says too many hoops. bonded warehouse  regular inspections lots of paperwork. try it without telling them and  you are in big trouble,if you dont blow yourself up of course. i believe some  eastern europeans may be able to help.

But, but ... I (and many others) have been distilling methanol for years.  Let's hope there's a  difference between making and recovering!

It looks simple to produce. Could be pretty handy in a petrol back up genny, so long as the fact wasn't broadcast all over the place.

Another downside is that it's not a direct substitute for petrol as there's a significant difference in the KW/Kg, so runs too lean, which is bad. Hence those 'dual fuel' cars that adjust the fuelling for E85.
B100 contains a bit less energy than derv but doesn't cause us problems (modern dpfs excepted etc.)
Plus it's hygroscopic, like methanol, but not as corrosive (maybe).

For a genny, tinkering with some misfuel, often 90% petrol, is worth a go, I reckon.
