I started this topic some time ago. I didn't get any reply.

There was a man in China that lived in a sustainable way that should be
achived by all people on the planet. Coal was found under his house and it
was dug out causing his house to sink and colapse and he was moved to an
apartment where he no longer lives in a sustainable way.

" The syngas produced from gasifying such biomass feedstocks as corn stover,
wood by-products, and chicken litter is more difficult to clean up than
natural gas-based syngas but much easier than coal-based syngas."

*Syntroleum Announces Successful Completion of Coal-to-Liquids Demonstration

Syntroleum Process(R) Tested With Live Coal Synthesis Gas

TULSA, Okla.--(BUSINESS WIRE)--Nov. 8, 2007--Syntroleum Corporation (NASDAQ:
SYNM), a synthetic fuels technology leader, has successfully completed a
demonstration of its proprietary technology designed to convert coal into
clean synthetic liquid fuels. The test run utilized synthesis gas produced
from coal and Syntroleum's proprietary cobalt catalyst technology in the
conversion process. The 2,500-hour bench-scale test run was recently
completed at Eastman Chemical Company's Kingsport, Tennessee facility.

The demonstration proved that fuels made from coal have the same superior
synthetic Fischer-Tropsch (FT) qualities as those made from natural gas. The
demonstration also proved that Syntroleum's proprietary cobalt-based
catalyst performs robustly under real-world coal-to-liquids (CTL)
conditions, as was predicted from earlier extended life tests performed by
Syntroleum.

"We have now proven that the Syntroleum Process(R), and specifically our
cobalt catalyst, performs very well on live coal syngas in a commercial
environment," said Jack Holmes, CEO of Syntroleum. "This is a great step for
Syntroleum and we continue to believe that this technology will help pave
the way to lowering our country's reliance on foreign sources of oil, by
producing domestically sourced synthetic diesel and jet fuel. This
successful demonstration under the most challenging condition of live coal
derived syngas is also very important for the future of our Biomass to
Liquids technology. The syngas produced from gasifying such biomass
feedstocks as corn stover, wood by-products, and chicken litter is more
difficult to clean up than natural gas-based syngas but much easier than
coal-based syngas. By demonstrating the commercial viability of our cobalt
catalyst for coal, we have also addressed its suitability for any renewable
feedstock. These results in conjunction with the Air Force's successful
testing of our Fischer-Tropsch jet fuel last fall and the recent
certification of FT jet fuel for the B-52 H Stratofortress bomber create a
unique opportunity for Syntroleum to supply synthetic jet fuel from several
sources to help the Air Force meet its target of providing 50 percent of its
needs with a 50/50 synthetic blend by 2016."

As previously announced, Syntroleum has contracted to deliver 500 gallons of
renewable synthetic jet fuel for testing by the Air Force. This fuel will be
made using Syntroleum proprietary Biofining(TM) technology using a mixture
of low grade animal fats and greases as provided by Tyson Foods. Based on
preliminary testing, Syntroleum believes this renewable fuel has almost
identical properties to the natural gas-based FT jet fuel used in the
certification tests.

Syntroleum has finalized a non-confidential white paper addressing details
and results of the coal synthesis gas test. The white paper can be found on
