Dorn is a founding member and board president of farm hack, is director of Greenstart, and– as his bio on their webiste totes– on his 250-acre family farm in Lee, NH, “has worked to select effective cover crops, grains and oilseeds for food and energy production, and has designed, constructed, documented, and shared systems for small-scale grain and oil seeds processing, biofuel production,  and no-till and low-till equipment to reduce energy use and increase soil health.”

Also, in his spare time, Dorn find time to contribute to our Almanac. You won’t want to miss this interview. Tune in, as always, at 4:00 P.M EST to Heritage Radio Network.

a wealth of information on biofuels

contained in a note from our friend Lucas Patzek:

My father works extensively in the thermodynamics of biofuels (and other energy sources), so you might want to check out some of his papers if you’re interested in this subject:

The most popular paper he ever wrote was published in Critical Reviews… in 2004.  Here is the web version of this paper:

The simple first law paper two parts is here:

A critique of the cellulosic ethanol is here:

A second law thermodynamic analysis of sustainability of industrial corn agriculture is here:

An energy analysis of a sustainable farm (Sunshine Farm in Kansas, part of the Land Institute) is here:

Almost all of his ecological publications are here:
