I used to have the plans for a biomass cracking plant that Henry Ford used to make methanol in his back yard. He burned it in his car trying to show the American people that it was cheaper than gasoline. The plans were quite simple as I remember. The US government (notice I didn't say American government) made the hemp he used illegal but he continued making home brew fuel for 4 years anyway. I don't know what I did with the plans but I remember it was a simple to build and use set up. The article said any biomass (plant matter) was useful but some worked better and faster than others.
Once in a while I'll find or hear of a dairy around here that has a methane trap built in the roof of the cattle barn which provides most of the energy to heat the barn. The owners are always very hush hush about it cuz the US government doesn't like us burning anything unless we buy it from them.
Do a search on biomass cracking plant on the internet to see what turns up.
The article said every house should have one of these little plants in the back yard making their own fuel for their car, hot water, cooking and home heating from what ever plant matter was available in their area.
If that search doesn't bring any answers, try doing a search for a guy named Jack Heror. (might be double r, can't remember) He wrote a book I read years ago called The Emperor Wears No Clothes which discusses cracking biomass for methanol, it may have some leads. I think his book is still available.
Yes, I just did a google search on the book emporer wears no clothes. Jack has a web site, his last name is spelled Herer. Looks like most of the book can be read on line without buying it in hard copy. The guy is pro marijuana so if you're not interested in that subject, just over look any info there and read what is discussed about energy. It was many years ago that I read it but I recall it was a very informative book.

On another note, reading through this thread, I know my plane will fly on orange juice. I spilled some on the wing one time and it still flew just fine. I quit drinking about 10 years ago or else I'd try spilling some orange juice and vodka on it. I'm sure the plane would still fly, just not sure how well I could.
