Warning: Biofuel may harm your health
As a cure for our addiction to oil, ethanol turns out to have some nasty side effects... Along with many of the same pollutants as gasoline, a large amount of unburned ethanol gas escapes into the atmosphere. That vapour readily breaks down in sunlight to form acetaldehyde, which can send ozone levels soaring.... While ethanol-burning cars will emit fewer carcinogens such as benzene and butadiene, they will spew out 20 times as much acetaldehyde as those using conventional fuel.
Doesn't look like ethanol is going to save us unless they design engines specifically for ethanol.
