|You are probably right about the energy to produce ethanol but if you
|use the sludge from the fermenting process, (put it through a oil press,
|(They work pretty neat for this application too)), the sludge will come
|out as a solid round cake like rod that can be broken up in to pellets,
|then dryad and then fed into the still as fuel.
|I have a pelletizer for converting alfalfa into feed pellets and it
|looks like it works on the same principal as a oil press, except their
|is no strainer and the water/oil removing chamber has much larger holes.
|
|Remember the conversion factor for potatoes to alcohol is only 20% so
|you 80% of the original spud left. This can be used as fuel or for
|cattle feed.
|
|I suspect that the commercial ethanol manufactures that use corn (big
|thing in Ohio, Indiana, and Illinois) first press the corn to remove
|the oil and syrups. Remove the corn oil from the liquid, wash out the
|sweeteners, and then ferment the starch into ethanol which is distilled
|out. Then what remains is used as cattle feed. So the economics are
|not just from ethanol but from corn syrup, Corn Oil, ethanol, and cattle
|feed.
|
|Back on the farm we used to go to the Sugar beet processing plant and by
|sugar beet pulp, (stuff left over after the sugar has been processed
|out) for cattle feed. The stuff stank like high heaven but the dammed
|cows had an orgasm over it.

By steam, I mean a small boiler on your property that runs a
piston or two thus powering a generator of about 20 KW. Enough
to power a typical house. Could be wood fired or fueled by
whatever.
As for hydro, I am thinking of a small stream, much like we used
to see for powering grist mills. There are catalogs out for
people who want to run their own generators off of a local
stream. You just divert a little off (if you have a steep enough
drop) so that you can power your generator.
Again this was not for large scale but for local usage.
