How about some context, shall we?

The Fractionation of lignocellulosic biomass is energy intensive. "In the reactive fractionation step, hemicellulose is most easily hydrolyzed, requiring a
mild alkaline solution and temperatures in the range of 150 to 200 °C (302 to 392 °F). Next,
lignin is removed under more severe conditions requiring a pH above 10, temperatures less than
250 °C (482 °F), the presence of an oxidizing agent, and pressures below 600 psi. The resulting
"clean" cellulose is mostly free of lignin and hemicellulose and is a purified feedstock for
enzymatic hydrolysis." Where do you get the energy to heat your biomass?

Your statement is also misleading. The govt. is not specifically discussing incentives for converting biomass to ethanol, it IS discussing corn production, and your statement does not address mine that incentives will lead to farmers converting food and livestock feed production to ethanol production.

"Besides, starving children is rarely due to high price of corn. It is mainly due to population explosion and bad government."

I'm sure there is a special place in hell being prepared for you as we speak, high prices for food = demand destruction = starvation. Extremely simple equation. If you think people who cannot afford to eat will just lie down in the streets to die, I suggest you look at France just before the revolution and Czarist Russia just before the revolution.

Picture this. There are a bunch of debunkers making $7.00 hr. sitting at computers in little cubicles. They have a printout telling them what to try next if the previous post was challenged. I believe that is what we have had to deal with here since Stuart's 8% decline article.
