Well there ya go. Should have read down a bit first... Didn't know
glycerin was in the glycol production tree... There. I learned
something today.

Kinda cool the way this all comes together, this renewable stuff. Make
biodiesel to burn in a generator, say, end up with glycerin. Make
glycol from the glycerin, and put it into a heat exchanger (simple
coiled loop) around the genny exhaust to do some space heating with
hydronics ;-).

  Steve, do you do any cogeneration for heat with your diesel generator?

Yes, the heat from the engine is used to keep the veggie oil liquid with
a coolant loop in the fuel drum.

Sounds like that only uses a tiny fraction of the heat.

 Making Biodiesel can be done too.  Check out this article.

In case you think that article is bogus, here's another site:

or do a search yourself.

(The inventor is now recanting his story.. lol)


FYI - I read that making biodiesel also produces glycol that can be used to
         make antifreeze. Even better payback.
