<p>Quite awesome and the smelting pot demonstrates how much high
temperature can be created. Some version of this would I think be
adequate for Rolf's first proof of concept trial, better than
using his gasifier. How big have you made one without compromising
the key parameters?<br>
</p>
<p>Our colleagues are responding to the wake up call, and when a few
$$ are available, the ceramic project will be able to draw from
the best people and technologies in the business. In the mean
time, we can all contribute to assembling Rolf's projects needs,
and I hope others will join in and help make it happen.</p>

The AVUD method is ignited at the level of the "grate" (actually a
pipe with holes on side and bottom, so the char can pass around
the pipe, drop below the hot zone, and be extracted at regular
intervals). The heat rises and pyrolyzes the biomass above, and
additional fuel is added regularly on top of the fuel pile. That
makes it a continuous process. No need to stop.<br>
<br>
The tarry gases exit and are combusted with turbulent air, coming
from an air compressor. The combustion is quite complete and
clean. This has similarities to the Dasifier made by Agua
Das almost 20 years ago. You should read these materials at my
website: <br>

Many years ago Das was one of my teachers and mentors, and a good
friend of Tom Reed.<br>
