Hey Tom et al;
I think I might have a new solution for our woes re. re-use of
methanol. Rather than trying to dry it for re-use in making BD we might
be able to just use it for fuel. This local dude who is way into
performance diesels comes into my place last night to talk about BD
Propane is also used, but metanol would be more controlable and less
volitale.
