Newfangled? HardlyA lighthearted look at biofuels through time04 Dec 2006
The way most people talk about biofuels, you'd think they were a brand-new invention. But using natural products for fuel is an idea as old as the hills, as this highly selective timeline demonstrates.
Mid-1800s: Soap-makers begin to transesterify vegetable oils -- you know, exchanging the alkoxy group of an ester compound by using another alcohol, often catalyzed by the addition of an acid or base. Ahem. Or, for you non organic chemists, breaking down one molecule and building a shiny new one. Transesterification (not to be confused with transvestite Transylvanians) produces methyl and ethyl esters, of which biodiesel will be composed in the following decades. Good, clean fun abounds. 1900: After experimenting with whale oil, the soon-to-be-famous (or at least familiar-sounding) Rudolph Diesel uses peanut oil as fuel when demonstrating his newly invented compression ignition engine at the World's Fair in Paris.

1912: In a speech, Diesel says, "The use of vegetable oils for engine fuels may seem insignificant today, but such oils may become, in the course of time, as important as petroleum and the coal-tar products of the present time." We might be getting there, Deez.
1920s: The diesel engine is altered to allow it to use a residue of petroleum, which is cheaper and more available than biomass fuel -- and government-subsidized. Decades of sooty, smoky madness commence.
1940: Henry Ford has his last dance with Mary Jane, closing his Midwest ethanol plant due to competition from the low price of petroleum. Mid-1970s: Fuel shortages lead to a revived interest in biodiesel by consumers, but the government hustles to subsidize the petroleum market. Biodiesel maintains its rep as an "alternative" fuel. 1982: Interest in biodiesel begins to perk up, as evidenced by the first International Conference on Plant and Vegetable Oils, held in Fargo, N.D. Because really, where else? 1984: The number of commercial U.S. ethanol plants peaks at a whopping 163. By the end of 1985, only 74 are still in business. 1985: Ford Motor Co. manufactures the first flex-fuel vehicles capable of running on gas, ethanol, or methanol. 1996: A boat called Sunrider, running on 100 percent biodiesel, circumnavigates the globe.
2001: Actor Woody Harrelson travels the West Coast on a bike, caravanning with a hemp-fueled bus, and creates a documentary about it. He also smokes a lot of weed, but you didn't hear that from us. 2004: Government vehicles in the Philippines are required to use 1 percent biodiesel from coconuts. 2005: Minnesota requires that all diesel fuel sold contain at least 2 percent biodiesel, the first such law by a U.S. state. 2006: Grist launches eye-opening series on biofuels, fills gaps in public understanding, takes step toward solving world energy crisis. Hooray! |
