With Cellulosic Ethanol, There Is No Food Vs. Fuel Debate
I commented several times on the stupidity of corn-based ethanol as a substitute for gasoline. It’s a very inefficient process and provides fuel at the expense of food. Already ethanol is raising the cost of growing livestock.
However, cellulosic ethanol (alcohol made from the other parts of plants, not from the edible portion) has great promise.

Ralph,
There is “great promise” only if you accept the thin claims and speculations of the cellulosic ethanol enthusiasts. The logistics of collection and transportation will be complicated, and the energy balance of the more complex processes (assuming that they can work) is unknown. The other major consideration is the long-term productivity of lands from which gigatons of biomass are removed. Other environmental considerations could also be significant.

Well, my tentative conclusion would have to be that there is no possibility that corn ethanol will make a net beneficial contribution to energy supply, taking into a account all costs.
There is a chance that use of waste plant material will despite great obstacles at present.
If all of the money “invested” in Iraq was devoted to hydrogen research we would probably already be very close to switching over…
The biggest hurdle the cellulosic ethanol producers face at the moment is the cost of the enzyme needed to breakdown the cellulose into a sugar. While everyone from private industry to the US govt is throwing money at these research projects, we have yet to hear how they are going. I posted last week on this topic specifically in the article, “Cellulosic Enzyme Cost Reduction is still a WIP”.
Taking away our dependence from corn requires a different ethanol strategy. One way to go about this is to empower local communities to produce ethanol from the best available feedstock. I wrote a long article yesterday on the benefits of decentralizing, or “regionalizing” alternative energy as it relates to ethanol production.
Not only does this support the local economy, but it reduces the strain on major ethanol crops like corn.
