We spend a fair amount of time huffing gasoline, but we've always been a tad afraid to actually drink it, as it's got a reputation for being rather toxic. Luckily for us, Shell and ExxonMobil are starting to put a big push behind GTL, a fuel derived from natural gas that could replace diesel in major metropolitan areas. Cleaner-burning than diesel, the fuel works in contemporary diesel engines, and thus could be a boon for municipal transit vehicles, as well as heavy trucks and diesel cars in metro areas with high pollution. Plus, possibly most importantly, according to a Shell exec, "You can drink it. You won't feel great, but you won't die." In fact, a kosher version of the substance is actually used to line drink boxes. L'chaim!
