Re: [biofuel] Yields
I can't think of any grains right off hand that don't store their NRG as starch. If you catch these grains before they're fully mature, then you may find some simple sugars present. But not for long. That's the story with sweet corn. Sweet=sugar ie. readily available and mobile NRG source but as soon as it looks like tough times (picked or end of season) sugars are converted to storage/starch for use later when the seed germinates (if someone doesn't eat it first). Hey, an inteeresting thought- those biodegradable packing peanuts are pretty much pure starch. Maybe NAH!

[biofuel] Yields
People and Sam, A point that everyone might have missed fromthe table below that Sam posted earlier is that while this table shows the yield per ton it isbased on the natural air weight of the product listed ie it includes water eg. wheat and corn both have approx water contents around 12% on average (and close on 75% carbohydrate levels) whereas potatoes and sugar have water contentsquite often up in the high80s %wise (andcarbohydrate levels of 90% when the water is removed). This is a point that always has to be remembered when dealing with any plant product and calculating the conversion efficiency. If you leave the ethanol manufacturer out of it what it comes down to is the yield per acreas far as the grower goes and if you leave the grower out the yield per ton asfar asthe etahnol manufacturer goes.
