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:
