<div dir="ltr">Moderator: I changed the subject line. This is
in response to Crispin's comment about Anand Karve's work.
<div>---------------
<div>
<div> </div>
<div>Crispin: "<span style="font-size:12.8px">That is
what is so inspiring about AD Karve?s work on
charring waste </span><span style="font-size:12.8px">biomass to produce a high quality fuel. He
even produced the extruder and </span><span style="font-size:12.8px">the Sarai stove to go
with it. That is a museum quality piece of work -
to </span><span style="font-size:12.8px">be
studied... "<br>
</span><br>
I take your word for it, but I also had this suspicion
a few years ago that what Anand Karve was proposing in
terms of converting waste biomass for charcoal was
worth more attention, not primarily as a fuel choice
issue but as a waste management issue. In dry regions
such as much of India, leaf and tree waste along with
other open biomass waste is a major problem in
municipal waste management. Why, just driving by
Gandhinagar - the capital of Gujarat state where I
lived - a few months ago I saw huge piles of leaf
waste in numerous parks that have been created by the
state government to make the city "green". All those
leaves will be burned in the open, contributing to air
pollution (not reported in peer-reviewed literature so
it must not exist) that damages biota health here and
now. On the other hand, such burning will release
organic aerosols that supposedly cool the atmosphere,
so it is most definitely "green" for the "global
environment" advocates. <br>
<span style="font-size:12.8px"><br>
Open organic waste - including leaves, tree debris,
food waste - is a huge headache for local
governments. On the other hand, urban trees have
multiple benefits including <a href="https://www.accessscience.com/content/urban-tree-leaves-remove-fine-particulate-air-pollution/BR0116141" target="_blank">air
filtering</a>, favorable changes in ambient
temperatures (thus impacting building energy demand;
I did some work for Cinncinnati Gas and Electric
climate options 20+ years ago), and I also happen to
like urban forestry, gardening, food production (if
land, water, and air quality so permit). <br>
<br>
A new paradigm of urban/peri-urban biomass
production, utilization, and waste management needs
to emerge, and energy analysts have much to offer. </span></div>
<div><span style="font-size:12.8px"> </span></div>
<div><span style="font-size:12.8px">Unless they leave
the field to WHO and EPA. <br>
<br>
</span></div>
<div><span style="font-size:12.8px">The question is,
do Indian customers care to advance to cleaner
charcoal or convenient LPG? <br>
<br>
As I mentioned in the previous post, the commercial
potential may not lie in household cooking but in
water heating (peri-urban, rural) and
commercial/institutional cooking and heating
(water/space). </span></div>
<div><span style="font-size:12.8px"> </span></div>
<div><span style="font-size:12.8px">****<br>
<br>
Crispin: "But he is promoting charcoal consumption -
very offensive to some. Shall </span><span style="font-size:12.8px">we forgive him too? :)"</span><br>
<div><br>
Asking forgiveness from sinners of cooked science?
You must be joking, Mr. Pemberton-Pigott. </div>
<div> </div>
<div>I note your emoticon, but this is no laughing
matter. I think it's time to stop blaming direct use
of solid fuels for presumed envionmental ills.<br>
<br>
It's the process that matters. Converting primary
solid fuels into an energy service can be "dirty
process" or "clean (or cleaner) process." <br>
<br>
Extending Kirk Smith et al (AREE 2000 on India) to
all processes of solid fuel transformation, not just
final combustion, and counting all emissions, could
well show that investments at all steps of the fuel
cycle can deliver small-scale direct use of solid
fuels at a lower emission rates than the
"traditional" processes (unprocessed solid fuels
with relatively uncontrolled combustion and no
emissions capture or ventilation). </div>
<div><br>
I will send you and Ron an e-mail about solid fuels
and "dirty fuels"; you decide if it would add rancor
or value to this List. I too prefer gas,
electricity, and solar (thermal or soon enough,
induction cooking via PV). There are markets for
those. But until the 3 billion people we bleed our
hearts and research funds on get to that nirvana,
reducing the PICs and the drudgery of cooking should
be the prime goals of research on solid fuels use.
Banning solid fuels should be limited to some areas
and some users. <br>
