Remember the MicroFueler that came out last May? Well, Sierra Nevada, the beer brewing company has figured out that you can also use beer to make ethanol as beer contains yeast.
I am seriously going to get one of these beasts as soon as I buy my first house. Think of all the beer I can re-use!
Sierra Nevada, brewer of delicious beers, has purchased a MicroFueler, a contraption that produces ethanol from water, sugar and yeast. Yeast also happens to be a major byproduct of beer fermentation, allowing them to make fuel out of beer leftovers.
