<DIV><FONT face=Arial>Dear Ron</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>In answer to your question "Anyone else like it? ", I am
enormously impressed with Paul's slide show presentation! </FONT></DIV>
<DIV><FONT face=Arial>It shows clearly the importance and advantages of "using
wastes at their highest value level". His TLUD stove system fits in very well
with his local Vietnam circumstances, where rice growing waste (straw and hulls)
is in abundance. However, the important concepts should be adaptable to many
other "agricultural situations" throughout the World. </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I think this is an excellent practical example of a way to
implement the concepts of "Think Globally and Act Locally", and "Small is
Beautiful." It outlines very low cost ways where a small farmer can utilize his
wastes advantageously, to increase his net annual income.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>These are excellent presentations, that should be read by
anyone interested in Sustainability, and waste resource
utilization.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Best wishes,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>

<DIV><BR></DIV>
<DIV> This is to strongly recommend Paul's PPt, identified below.
Don't think you can get through it in a few minutes, as it is 175 slides
long. But if you want a very full lesson on why biochar makes sense, the
last half (?) is better than any other biochar PPt I recall seeing, save some
from Johannes Lehmann, maybe.</DIV>
<DIV> I fault it only in minor ways. He fails to mention
that his stove will undoubtedly rank very good in improving air quality.
He fails to mention that his fan power level control will save cooks a
lot of time (which can translate into money). He fails to mention enough
on the horrors of charcoal making for charcoal-using stoves.</DIV>
<DIV> The first part is not on either stoves nor biochar.
But still fascinating and most educational.</DIV>
<DIV><BR></DIV>
<DIV> I expect to similarly laud his paper tomorrow. Now it
is too late to have done more than skim it.</DIV>
<DIV><BR></DIV>
<DIV>Paul - thank you for an amazing effort. I next send this to the
biochar list</DIV>
<DIV><BR></DIV>
<DIV>Anyone else like it?</DIV>

this paper I distinguish four type of waste in descending order of nutrient
content.The first two types of waste are putrescent, the last two types of
waste are non-putrescent. The main idea here is that each type of waste
should be transformed and returned to agriculture by means of the most
appropriate technology. This gives the highest economic return. Type 1 waste
should not be processed as if it were type 2 waste, type 2 waste should not
be processed as if it were type 3 or 4 waste, and type 3 waste should not be
processed as if it were type 4 waste. <BR><BR></DIV>
<DIV>In applying these technologies, we produce vermi-compost,
mesophilic compost, thermophilic compost and biochar. These different soil
enhancers do not compete with one another. Instead they all complement one
another in a powerful way. I was compelled to write this paper because I so
often saw (and still see) funding agencies lining behind a particular
technology in a very narrow manner. Look, for example, at all of the money
poured into biogas plants. But does this make sense? I question the wisdom
of making fuel out of pig waste (type 2 waste), since there are other
technologies that allow us to derive far more income out of this type of
waste. If its fuel we need, let us turn to type 4 waste.<BR><BR></DIV>
<DIV>Many thanks.<BR></DIV>

class=gmail_quote>Dear Andrew P<BR><BR>Good points. The stove community
projects are not threatened by failure of<BR>the PV subsidies but they are
certainly affected by the (looming?) collapse<BR>of the carbon trading
market. A number of castles have been built in the<BR>air. Recent emphasis
on the health aspects of smoke inhalation will probably<BR>provide a more
grounded source of development revenue. The recent doubling<BR>of the
estimated number of people who die from cooking fire smoke
will<BR>probably enhance interest.<BR><BR>The programmatic problem I have
encountered with this is that cleaning up<BR>indoor air can be done
without improving the stoves at all - just piping it<BR>outside where
'dilution is the solution to pollution', to quote and EBRD<BR>consultant.
Inventors want to create stoves, not just clean up the air.<BR><BR>The
fuel saving aspect of stoves will always remain a strong contender
in<BR>the funding cycle because it is an easy sell. Certainly easier than
resource<BR>creation and management. Better to whine over how little there
is than to<BR>create more.<BR><BR>I am not so sure how the broad
translation of agriwastes into fuel is going<BR>to be viewed by the people

<DIV class=h5>Paul,<BR><BR>Solar City does not exactly provide solar
installation for free. They<BR>provide an option in which they will
install a complete system with no money<BR>down, but it involves a
long-term contract (purchase option after 5<BR>years) in which the
customer buys the electricity generated by the panels at<BR>a set price (I
am guessing that option requires the existence, beyond<BR>federal
subsidies, of state, local and utility subsidies for solar
panel<BR>installation and solar generated electricity).<BR><BR>I am not
poo-pooing the idea. It is a sound model. It would be sounder
if<BR>it did not rely on subsidies.<BR><BR>Where there is a strong market
for rice husk char and ash, I agree that such<BR>a model could be used to
market char-producing stoves to provide energy to<BR>the customer in
exchange for char and ash, and a fee, if needed. I truly<BR>hope you
can convince someone to
invest.<BR><BR><BR><BR>_______________________________________________<BR>Stoves
