CNET News.com: "To make ethanol, you want to make vinegar first, according to ZeaChem.
The biofuel start-up, which has moved from Colorado to Silicon Valley, says it has come up with a method of making cellulosic ethanol that results in close to 40 percent more fuel per ton of wood chips than competing processes. By 2010 or so, the company hopes to be producing ethanol commercially for 80 cents a gallon at wholesale. That could translate to anywhere from $1.10 to $1.50 at the pump, depending on a host of factors."
I have a new fascination with green technologies in general. What's interesting about them is the different types of thinking required to develop it, and overcoming the many obstacles a start faces.
