It would be easier to make biogas with a digester. Biogas is a mix of methane, carbon dioxide, and hydrogen. It comes from bacterial composting, not from fermenting with yeast, like ethanol.

It works better if the grass first goes through a sheep, chicken, goat, or cow to get the plant breakdown process going. It is pretty easy to convert an engine to run on biogas, but your horsepower rating will likely drop by about 1/4.

Mother Earth Magazine has some online articles about it. Just search the archive. Here is a link to some books that can also get you started:

You could also use any extra to heat/cook with/light your place.

I know a few farmers who use it to heat their cow/chicken barns in the winter.
