Beer-based Ethanol is the Best/Worst Idea for Car Fuel

A New Zealand chemist has found a good use for spent yeast normally discarded after brewing beer, Popular Mechanics is reporting (via AutoFocus).
It’s not the first time beer-based ethanol has been used to power cars, but New Zealanders can fill up on 98-octane (!) booze-fuel for a limited time. The mix is 90 percent gas to 10 percent beer ethanol.
(Note: I covered parts of the 2008 Democratic National Convention in Denver and remember the Coors-powered cars in Denver and think it’s the best imaginable use of Coors Light)

New Zealand-based brewery DB Exports calls their fuel “Brewtoleum,” but they have a much more clever marketing campaign.

Alcohol and motors are nothing new: Top Alcohol dragsters, most cars on the road in Brazil and corn-fed ethanol in the states.
But for beer-producing states in the United States (California, Michigan, North Carolina, Colorado, Oregon and the other 45 states in the union) the spent yeast conversion could justify keeping whatever it is that Anheuser-Busch makes these days around for longer.
