<DIV><FONT size=4 face=Calibri></FONT> </DIV>
<DIV><FONT size=4 face=Calibri>Consider the concept where the Earth is divided
into two Zones:</FONT></DIV>
<DIV><FONT size=4 face=Calibri>1: The "Biosphere Zone", where plant and animal
life exists, and which includes the elements and compounds necessary for
sustenance of their lives and existence as living entities.</FONT></DIV>
<DIV><FONT size=4 face=Calibri>2: The "Non-Biosphere Zone", containing the
elements and compounds that are not accessible by the life forms in the
Biosphere.</FONT></DIV>
<DIV><FONT size=4 face=Calibri></FONT> </DIV>
<DIV><FONT size=4 face=Calibri>Clearly, if no additional carbon is brought into
the Biosphere, the carbon content of the Biosphere cannot increase.
However, if coal or oil, or other forms of carbon, are brought into
the Biosphere from the "Non-Biosphere", then the carbon content of the
Biosphere will be increased. Similarly, if wood from the Biosphere, containing
carbon is burned, there is no net addition of carbon to the
Biosphere.</FONT></DIV>
<DIV><FONT size=4 face=Calibri></FONT> </DIV>
<DIV><FONT size=4 face=Calibri>The problem with increased CO2 in the Atmosphere
fraction of the Biosphere is not combustion, but rather, the problem is the
source of the carbon combusted. If the carbon was sourced from the Biosphere,
there is no net addition of C to the Biosphere, although there would be a
transitory dislocation of carbon from one region of the Biosphere to
another.</FONT></DIV>

<DIV>Dean & John,</DIV>
<DIV><BR></DIV>
<DIV>The simple fact is that no combustion device will ever remove carbon from
the atmosphere. If a fundamental problem is that there is too much CO2
[carbon] in the atmosphere, then removing carbon from the atmosphere is an
essential imperative.</DIV>
<DIV> </DIV>
<DIV><FONT size=4 face=Calibri># There would be no problem if only biomass was
burned, and if the annual quantity burned was equal to, or less than, the
"mean annual increment of biomass growth."</FONT></DIV>
<DIV><BR></DIV>
<DIV>The most direct, simple and proven way to remove carbon from the
atmosphere is the pyrolysis of biomass. Therefore, what we need are
heating devices that are based on pyrolysis. Combustion is both old
school and not an answer to the imperative of carbon removal.</DIV>
<DIV><FONT size=4 face=Calibri></FONT> </DIV>
<DIV><FONT size=4 face=Calibri># "Pyrolysis" is simply the destruction of
biomass by heat. ALL stoves are "pyrolysis stoves." "Combustion" releases the
energy contained within the pyrolysis gases. I think what you are intending to
promote are "char making stoves". Note that "charcoal burners" do not add
additional carbon to the biosphere.</FONT></DIV>
<DIV><BR></DIV>
<DIV>For the record, Jerry Whitfield, who designed and manufactured the first
working wood pellet stove in 1984, has now developed the designs for a
pyrolytic parlor stove. Unfortunately, at this time, there is no market
for the carbon [biochar] that such a stove would create. Until such time
as the imperative of removing carbon from the atmosphere is recognized and
valued, perhaps a significant carbon tax, there is no way to commercialize
pyrolytic devices in general, much less for residential use. It may also
be required that we reject the old industrial era model of extraction and
exploitation and replace it with a model more early akin to regenerative
stewardship, with an eye towards a future that could be vibrant, dynamic and
abundant. </DIV>
<DIV> </DIV>
<DIV><FONT size=4 face=Calibri># There are two issues here:</FONT></DIV>
<DIV><FONT size=4 face=Calibri>1: Efficient, effective and safe
stoves</FONT></DIV>
<DIV><FONT size=4 face=Calibri>2: Removing CO2 from the
atmosphere.</FONT></DIV>
<DIV><FONT size=4 face=Calibri></FONT> </DIV>
<DIV><FONT size=4 face=Calibri>#Given that the wood energy distribution is
about 50% in the Char and 50% in teh pyrolysis gases, a person wanting an
efficient, effective and safe stove would have to consume roughly twice as
much fuel for the same stove effect. If the "Stove Owner" could exchange the
char for an equal "energy content of new fuel", then he might go for it.
The Fuel Seller" could then sell the charcoal to another person wanting
charcoal fuel, OR, he could sell it to an Organization that wanted to "Remove
CO2 fromm teh Atmosphere."</FONT></DIV>

technology is developing quickly to mitigate global climate change. We
don't have any time to lose if wood and pellet heating technology is going
to compete amongst the renewable energy solutions.</DIV>

<DIV style="FONT-FAMILY: arial,sans-serif; FONT-SIZE: 13px">Pellet stoves
and then automated pellet boilers were a huge technological step forward.
We believe a next step may be affordable, automated wood stoves to

Building off the very successful Wood Stove Decathlon, we will test,
assess and help improve up to 6 automated biomass heating stoves, who will
be competing for a modest prize. Instead of a large event open to the
public, this will be an intensive 4 days for 30 stove professionals to push
the envelope of stove innovation.</DIV>
