How Make Ethanol At Home
How is cellulosic ethanol made? As with producing ethanol from grain, processing cellulosic sources extracts the fermentable sugars from the feedstock for distillation into alcohol. Unlike in grain, the sugars in cellulose are locked in complex carbohydrates called polysaccharides, or long chains of simple sugars. Separating these complex structures into fermentable sugars is essential to the efficient and economical production of cellulosic ethanol.

Starved For Energy
Energy: Despite huge subsidies and tax breaks, the only thing ethanol seems to be accomplishing is eating up the corn supply. Consider that one tankful of ethanol could feed one person for a year. If there were an example of the law of unintended consequences, it would be ethanol, a fuel aimed at making us energy independent by relying on a homegrown resource corn. A year ago Indiana Gov. Mitch Daniels decided his corn-rich state would make ethanol use widespread. He designated the town of Reynolds, population 550, "BioTown USA." Reynolds was to be a showcase, the first town to run entirely on renewable energy. But the law of supply and demand got in the way. The question quickly arose: Do you install ethanol pumps at $50,000 a pop when there are few cars to line up at them or do you try to sell vehicles that use ethanol when there's no place to fill up? There are 6.5 million flex-fuel vehicles in use nationwide, less than 2.5% of all vehicles.
Donnelly: Ethanol can boost economy
Energy independence is a major goal for Democratic congressional challenger Joe Donnelly, and improving the economy of the Midwest is another. The Granger Democrat believes one way to reach both goals is to boost U.S. ethanol production. Currently, Donnelly said, too much money goes to buying foreign crude oil and foreign energy sources, and could be replaced by increased ethanol production. .
Chocola: Explore, conserve more fuel
SOUTH BEND -- U.S. Rep. Chris Chocola says he has a four-point plan for reducing energy costs that starts with finding a way to lessen its reliance on foreign oil and includes increased domestic exploration, more conservation and making sure that price gouging isn't tolerated. Energy costs become a "personal experience" when we pay $3 a gallon at the pump, Chocola said, but the whole cost of energy includes the fuel we buy to heat our homes and even buying things made out of plastic. To start with, Chocola said, "we need to have alternative sources of energy like renewable fuels, which is ethanol, biodiesel and also alternative fuels, which would be things like wind, solar and battery." "We also need to increase domestic production of traditional fuels, like oil and gas," he said.
