Gasifiers????


My daughter, bless her, sent me these links

Washington D.C. (AP) - Federal and city officials have now seen a machine
touted by D.C. Councilman Marion Barry as a revolutionary way to create
pollution-free energy
<snip>
The Ward Eight Councilman and activist Dick Gregory displayed the machine
Thursday in a Southeast Washington parking lot.

The gasification machine's inventor, Simon Romana, says it can use garbage
or sewage to create pollution-free electricity and drinking water.

Romana says his machine burns hotter and cleaner than sewage gasification
plants and large incinerators, but he won't explain why.

For over 20 long years Dr. H. S. Mukunda of Indian Institute of Science
[IISc], Bangalore has devoted his attention to an obdurate lad of much
promise in the world of alternate energy sources - the gasifier! Step by
patient step, he has made it a viable technology and a critical scientific
community is beginning to take notice.

Gasifiers were darlings of the petroleum starved world during the war years
of the 1940s. Despite the problems that riddled them, people endured them
since they burnt wood chips or coal to produce gas that drove trucks and
buses built originally for petrol and diesel. Once the war was over they
were forgotten -- with a sigh of relief -- except by a few enthusiasts.

"Solar energy captured by photosynthesis and stored in biomass can be
converted by the process of gasification into a high-energy fuel that can be
used in internal combustion engines for power generation," says Dr. Mukunda.
The combustible gas -- popularly, producer gas -- is composed of about 20%
Hydrogen, 20% Carbon Monoxide, 3% methane, 10% Carbon di Oxide and the rest
Nitrogen. "The gas will fuel a spark-ignition engine delivering about 60% of
the power of gasoline, or it will run a combustion-ignition [diesel] engine
in dual-fuel mode, eliminating the need for 75 to 85% of the diesel fuel."

Obviously the promise was vast. But the equipment then, was strewn with
problems. Gas production was erratic, the gasifier quickly clogged with tar
and consequently maintenance was frequent and messy. Gasifier design called
for getting too many conflicting elements right and that's what tired
researchers.

Around the same time as IISc began to be interested, in far Colorado, USA
Dr. Thomas B. Reed was also conducting his re-examination of the old
promise. Dr. Mukunda credits him with many of the insights that have revived
the gasifier.
