Pig Manure Eyed as Energy

URBANA, Ill. (AP)--A University of Illinois research team is working on turning pig manure into a form of crude oil that could be refined to heat homes or generate electricity. Years of research and fine-tuning are ahead before the idea could be commercially viable, but results so far indicate there might be big benefits for farmers and consumers, lead researcher Yanhui Zhang said.

Here's an example of some folks working with interesting small scale 
applications of gasification of biofuels

The two-year experimental project is intended to collect data on biomass feasibility with an eye towards making the energy source efficient and affordable.
Shasta Energy Group is one of the groups involved in the demonstration project.
"A 50 kW gasification unit connected to the grid will be the first of its kind," said Thomas Deerfield, Shasta Energy Group's Biomax 50 project manager. "Part of the project is to smooth out the process of connecting biomass electricity to the grid."

 Mobile application.. (not as convenient as liquid fuel.. however energy 
losses, such as converting biomass to EtOH. could be avoided)

For this purpose, may I recomend sodium borohydride as a carrier for
hydrogen.  Fuelcell-electric tractors and trucks are perfectly
feasible with a bit more development, and sodium borohydride/water
solutions are about one quarter as energy dense as gasoline.  Coupled
with the higher efficiencies of fuel-cell electric drivetrains, it is
pretty close to a direct replacement for gasoline/diesel, with the
advantage that the mixture is essentially non-flammable without a
catalyst present.

It's specifically about Conoco's process, which the company is apparently pushing agressively.  There are a couple of charts on the page about Conoco's process that show $ / bbl ($23) and process efficiency in bbl / MMCF (122).  I think that's bbl of diesel fuel, since that's what the process is optimized for.  Not sure what that translates to, in terms of energy content of feed vs. product, or whether it accounts for external energy in to the process.

Researchers in Berkeley Lab's Materials Sciences Division (MSD), working with crystal-growing teams at Cornell University and Japan's Ritsumeikan University, have learned that the bandgap of the semiconductor indium nitride is not 2 electron volts (2 eV) as previously thought, but is close to 0.7 eV.
