"Sugar Car" could make hydrogen on-board from sugar or starch

Perhaps we will one day be able to put starch or cellulosic materials directly into our fuel tanks, by-passing the need to make ethanol or other biofuels. That's what this research at Virginia Tech seems to be aiming for, increasing efficiency vs. the ethanol route. -- Jeff G.

"The vision is for the ingredients to be mixed in the fuel tank of your car, for instance. A car with an approximately 12-gallon tank could hold 27 kilograms (kg) of starch, which is the equivalent of 4 kg of hydrogen. The range would be more than 300 miles, Zhang estimates. One kg of starch will produce the same energy output as 1.12 kg (0.38 gallons) of gasoline."

by Karen Woodmansee -- May 15, 2007
"'It (algae) starts out in a test tube and replicates itself,' he said. 'We can grow it in our test ponds. It is about a thousand times more productive to grow algae than growing oil seed in the dirt."

Brothers invent corn cob collection attachment for combines

Nebraskans Jay and Ty Stukenholtz of Nebraska have invented a device that can retrofit a combine for collecting corn cobs as it also collects corn kernels. Cobs could be used as a feedstock for cellulosic ethanol or butanol production. -- Jeff G.

U.S. to Invest in Small-Scale Cellulosic Biorefineries

It's good that a vatiety of cellulosic technologies are being tested to see which ones should be scaled up. -- Jeff G.
U.S. to Invest in Small-Scale Cellulosic Biorefineries : "The full-scale biorefineries will focus on near-term commercial processes, while the small-scale facilities will experiment with new feedstocks and processing technologies."
