Stepping out on a limb a little further, I'll venture that the bulk of the vehicles roaming the planet in the next mid-century will be electric, or maybe even hydrogen powered. The future for internal combustion engines in the mid 21st century will be ethanol-not the corn ethanol being pitched today that requires virgin raw materials, but ethanol made from beer waste. I've burned 105-octane E85 ethanol produced from beer waste in my GMC's L59 motor, and I'm here to tell you the future is beer. Instead of pouring millions of gallons of beer waste into the sewers annually like the breweries in California do, the folks at the Coors brewery in Golden, Colorado, recycle beer waste into automotive-grade ethanol. From the Coors brewery the beer-waste automotive-grade ethanol ultimately ends up as E85 sold at Diamond Shamrock stations across Colorado. It's not like brewing beer is going to go away anytime soon-the intoxicating liquid has been around for over 7,000 years. I've heard the argument that the demand for automotive-grade ethanol is threatening our nation's capacity to produce beer because of the threat to the corn supply. That's because they are diverting virgin stock from the front end of the distilling process instead of reclaiming ethanol as a by-product. I'm sure there are some who will say the millions of gallons of beer poured into the nation's sewers is only a drop in the bucket, but I don't agree. Not to stereotype anyone, but it seems like today's trendy microbreweries cater to the tree-hugger types who drive those orthopedic cars from Sweden. Maybe in the next 50 years or so the moonshiners ... er ... uh, microbrewers will recycle their beer waste from an on-site micro-refinery based in an old Norse country and then ship the 110-octane pure ethanol to the United States in Liberian-registered tankers. Instead of oil tankers like the Valdez running aground and creating a massive oil spill, a foreign registered ethanol tanker can crash and spill millions of gallons of booze into the ocean. Then the fish will get drunk, get promiscuous, and procreate like crazy. The next thing you know the world's food supply problem has been solved, and everyone is happy ... I tell you, it's a win-win situation! John Gilbert
