Are we really this hard up for gasoline? Are you absolutely certain that there's no other way??
In truth, the Californian Sierra Nevada Brewing Company has teamed up with those E-Fuel guys we told you about. E-Fuel has developed a system/machine to turn simple sugar and yeast into alcohol and then ethanol. (Really, it's not so different from brewing beer.)
Sierra Nevada is installing an EFuel100 MicroFueler in-house to turn 1.6 million gallons of otherwise discarded yeast for brewing (yearly) into the source ingredients of what we're sure is a very, very tasty high grade ethanol gasoline. We can drink to that. (beer, not ethanol)
