Green Diesel: New Biomass converter is far more efficient

Treehugger has discussed the silliness of ethanol production before , a process where it takes one unit of energy for every 1.1 unit of energy created. It was recently called "a subsidy business, not an energy business". Now it appears that the University of Wisconsin College of Engineering has developed a far more efficient catalytic reactor that generates 2.2 units of energy for every one unit consumed making it, and works with a wide range of plant material. This is a huge step forward from the zero-sum game that is ethanol. ::Phys-org
