The new butanol is a four-carbon alcohol, whereas ethanol is a two-carbon alcohol.
Later versions of the tool filled small tubes with ethanol alcohol (earning them the name "spirit level") and encased several tubes inside a long, wide body, which could rest on different surfaces.
In fact, millions of Americans already drive vehicles such as the Ford Taurus, the Dodge Caravan and the Chevrolet Silverado truck that can use alcohol fuels (ethanol or methanol) to reduce dramatically, if not eliminate, their consumption of gasoline.
We have the option right now to require that new automobiles sold in this country be capable of using alcohol-based fuels like ethanol, methanol or butanol instead of or together with gasoline.
For American motorists, that something better is cellulosic ethanol an alcohol made from straw, leaves, stalks, cane or, best of all, switchgrass, a hardy perennial that grows prolifically almost anywhere.
FFVs can be engineered to run on methanol and butanol, as well - alcohol-based fuels that, like ethanol, can be manufactured in quantity from abundant domestic sources.
That's what happened in Plaquemines Parish, south of New Orleans, where Earth Biofuels of Dallas last year announced plans to restart an alcohol refinery, closed since the first ethanol boom went bust in the early 1990s.

About 35% of the estimated 4.6 billion bushels of all U.S. corn grown this year will be consumed by the ethanol industry, producing nearly 14 billion gallons of alcohol.
For example, a federal requirement that new cars sold in America be capable of using methanol and ethanol, as well as gasoline, would create markets for such alcohol-based fuels and competition that will drive down gas prices.
Beer contains about the ethanol concentration that is achieved when cellulosic ethanol is produced (and in many cases, beer has a higher alcohol concentration).
