The fun thing about conferences is that there are also sorts of individual lines that presenters say that could be pulled to the headline, and perhaps be more mischievous than helpful. I was thinking that today, when the opening speaker began with explaining why she couldn’t start her talk with a joke. Turns out that when she tried to Google “ethanol and Joke” all she got was pages of citations of “ethanol is a joke” or “ethanol is a big joke!” Conference, you say, speaker, you say, but I thought the ASPO Conference didn’t start until tomorrow?
Well yes, that’s true, but sometimes if you want to catch some of the developing stuff, or the stories that never make it to the National Meetings, you can learn a lot from smaller conferences, and so I came to Dubuque. Today is the first of two days on “The Impacts of Increased Bio-Fuel Production on the Midwest Landscape.” At a time when the current ethanol situation has been described as “the farmer’s version of the gold rush,” it was interesting to hear what is happening down at the farm level and in planning within the Midwest to look at answers to the looming problem. Some of the papers today discussed switchgrass, and algae, and biodiesel and how to effectively harvest the “crappiest wood” in the U.S. and turn it into useful energy. And in the discussions, in a town where the corn grows right up to the airport runways, there was a lot of realism in the discussions of water needs, and soil nutrition replacement and bottom line cost levels.

"The opportunity exists to produce gas from grass or pellets from grass and heat buildings or even use it for transport,'' Samson told a seminar sponsored by the Frontier Centre for Public Policy in Regina Tuesday."This (biomass) is a very viable option for the transportation sector,'' said Samson, who's based in Quebec.
Yet governments continue to pour millions into subsidies to produce ethanol and biodiesel, which are less energy efficient than biogas produced from switchgrass, said Samson, who's been working in the field of bioenergy development since 1991.

Scouring the web with an eye toward understanding a bit more about the use of biomass-based ethanol as a replacement for gasoline, it has become apparent to me that there are a substantial number of "urban legends" emerging regarding the use of switchgrass as a feedstock for ethanol. More properly, these misconceptions are "rural legends," because at least from this former farm kid's perspective they arise from the fact that most people have very little connection to the land, and as such, are simply blowing a lot of wishful smoke about the details of a biomass-based fuel system. Hopefully the analysis below will shed a bit of light on the subject.
