If one device type promotes deforestation by consuming stick wood, but another technology reduces the risk of deforestation, should that not be in the plus column for the technology that reduces the risks of deforestation?</div><div><br></div><div>Using twice a much champagne fuel is, of course, a real problem. But using twice as much previously discarded waste as feedstock is a real plus. ESP. If we factor in the economic value of increased crops - which pure combustion devices can not offer.</div><div><br></div><div>Not all units on your list use the same fuels or are limited to a narrow range of fuels. How do we Give credit to TLUDs that can use a wide range of fuels, not just stick wood, which is a prime example of a champaign fuel?</div><div><br></div><div>Do we not have to use systems thinking approaches that take ALL of the factors in the whole system into consideration, not merely some arbitrarily selected sub-set?</div><div><br></div><div>It is not good science to arbitrarily select some sub-set of factors to tilt the outcome in favor of one particular technology. Frankly, combustion got us into the mess we are in and is unlikely to get us out. Pyrolysis might help get us out of the environmental mess we are in, but this is not a certainty.</div><div><br></div><div>Happy Earth Day!</div><div><br></div><div>Curious.</div><div><br><div>Jock Gill</div><div>P.O.

<div><font face="Arial">1: Would you agree with the following
statements?</font></div>
<div><font face="Arial">a: A "Stove" is a device with the primary purpose of
heating and/or cooking.</font></div>
<div><font face="Arial">b: A "Retort" is a device with the primary purpose of
producing char and pyrolysis gases</font></div>
<div><font face="Arial">c: A "Gasifier" is a device with the primary purpose of
converting a solid fuel into a fuel gas.</font></div>
<div><font face="Arial">d: A "Mixed Function system" (such as a TLUD) is a device
that provides both a heating and/or cooking function plus residual
char.</font></div>
<div><font face="Arial"></font> </div>
<div><font face="Arial">2: If you agree with those basic definitions, would you
not agree that a device attempting to do "2 jobs in one" cannot do either job as
efficiently or effectively as if the device was designed to do "one job the
best?"</font></div>
<div><font face="Arial"></font> </div>
<div><font face="Arial">3: Would you agree that the Customer who buys the "device"
should have the benefit of "true science based tests" that are repeatable
by others?</font></div>
<div><font face="Arial"></font> </div>
<div><font face="Arial">4: Would you agree that the Customer is the one who
decided whether or not he should purchase a "mixed feature device" that produces
char, but requires more fuel input, in contrast to a Stove that requires less
fuel input for the same cooking and/or heating effect?</font></div>
<div><font face="Arial"></font> </div>
<div><font face="Arial">5: Would you agree that the testing protocols for the
above "devices" should be such that the Customer should be able to compare the
various devices and then select the "device" that best meets
his wishes?</font></div>
