It's not exactly turning a sow's ear into a silk purse, but Cobalt Technologies Inc. is aiming to transform pine-bark-beetle-killed lodgepole pines into motor fuel.

A Colorado State University lab is preparing to test the brew from the California startup company in a four-stroke, overhead-valve Honda engine.

The aim at CSU's Engines and Energy Conversion Lab will be to measure the power output and air emissions of the fuel.

Using a proprietary fermentation process, Mountain View, Calif.-based Cobalt has turned lodgepole into the biofuel butanol, which is more like gasoline than ethanol.

"Butanol has some advantages," said Ken Reardon, a CSU professor of chemical and biological engineering.

Some motorists don't like ethanol because it has only two-thirds of the energy content of gasoline, resulting in lower mileage. Ethanol also can lead to corrosion because
the molecule attracts water from the air.
