Could DDG power ethanol biorefineries?

If they can make this work it might bode well for ethanol's energy balance since natural gas is one of the largest fossil fuel inputs currently. -- Jeffrey

Colorado Company Pursues Low-Cost, Low-Impact Technology to Develop Nation's Oil Shale Resources

This technology could make shale oil mining more feasible, but it would still require considerable power input for heating the rock. It would be interesting to see how much energy this will require -- Jeffrey
NETL: News Release - Colorado Company Pursues Low-Cost, Low-Impact Technology to Develop Nation's Oil Shale Resources:
News Release -- Jan. 10, 2007
"Composite Technology Development Inc. (CTD), Lafayette, Colo., is developing a technology that can heat the oil shale in situ, several thousand feet below the surface, separating the kerogen without mining the oil shale rock. If proven viable, the process could extract the petroleum-like liquid and render it mobile enough to be pumped to the surface."

MIT ethanol analysis confirms benefits of biofuels including ethanol

This latest ethanol life cycle analysis of ethanol is by an MIT graduate student. It looks at ethanol from corn kernels, corn fodder, and switchgrass. The good thing about this attempt is that she looks at a range of variables and comes up with probabilities for various outcomes. This approach is necessary because of the many uncertain variables in these calculations. -- Jeffrey
MIT ethanol analysis confirms benefits of biofuels - MIT News Office: "Regardless of the energy balance, replacing gasoline with corn-based ethanol does significantly reduce oil consumption because the biomass production and conversion process requires little petroleum. And further MIT analyses show that making ethanol from cellulosic sources such as switchgrass has far greater potential to reduce fossil energy use and greenhouse gas emissions."

MIT-led panel backs 'heat mining' as key U.S. energy source

MIT-led panel backs 'heat mining' as key U.S. energy source - MIT News Office:
Jan 22, 2007
"A comprehensive new MIT-led study of the potential for geothermal energy within the United States has found that mining the huge amounts of heat that reside as stored thermal energy in the Earth's hard rock crust could supply a substantial portion of the electricity the United States will need in the future, probably at competitive prices and with minimal environmental impact."

MIT: Hot Rocks could provide significant power source

This technique of fracturing hot rocks, injecting water, and extracting that water after it is heated is not limited to areas with natural geothermal activity at the surface. Hot rocks could be tapped close to where the power is needed. -- Jeffrey

Vinod Khosla responds to Terry Tamminen on ethanol

What I like about Khosla's approach is that he does not let the mirage of some unachieveable perfect answer stop him from pursuing answers that are imperfect. Rather, he works to improve the imperfect solutions including cellulosic ethanol. -- Jeffrey
