I'd love to read a real description of the energy in and out of that plant, including corn production. Their website is, predictably, full of manure. From their description: "or more accurately, harvest clean solar energy by way of our middleman, the humble cow" Uhh...last I checked, cows don't photosynthesize. What's interesting here is that they're a) using manure (via anerobic digestion) to fire the ethanol plant, and b) feeding the distiller's grain back to the cows. So they're using cows to recover energy from the waste products on the plant, and using that energy to run the plant itself. But you still have to grow corn and feed that into the plant. It still affects food supplies, and even if you accept their 5:1 corn-to-pump efficiency, that's still worse than sugar cane, much less the cellulosic ethanol stuff that's coming. I'll leave the merits of distiller's grain as cattle feed to a different discussion. The environmental movement really needs a few good macroeconomists. _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower
