Dear Tom,
can you get me on the terra preta discussion group? I would like to know
more about it. Is there a web site, where I can get detailed information on
this topic?
Yours
A.D.Karve

and hope the concept expands.  But I predict that in the future, that
charcoal will be found to be more valuable (higher economic return to the
charcoal producers and society) for sequestering (mixing in with soil) in
the same or other near-by field rather than for its energy value.

"biochar" (see www.iaiconference.org/2007conferenceagenda.html ) or "terra
preta" soils (see terrapreta at bioenergylists.org).   There are three
fundamental reasons for thinking sequestering will take priority:
>     a.  charcoal in the soil will provide out-year productivity benefits
for centuries in the future - rather than the one-time benefits of charcoal
for cooking.
>     b.  Those providing funds for carbon sequestration (and already a
growing "industry") will like the fact that there is an offset-multiplier
effect - as new (carbon-containing) fungi appears quickly, and the
multi-year productivity increase of reason #a is also a form of
sequestration - not available in any other form of sequestration.

every other type of simple stove in terms of efficiency, cleanliness, and
income-generating potential.  A bit more costly - but basically cheap - as
AD can confirm.

Although undoubtedly a little more expensive,  I believe that (future, not
yet available) "carbon credits" will make the charcoal-makers a much better
buy than the charcoal-users.  Since AD is active on both types of "charcoal
stoves" (and is knowledgable as well on soils), this is to ask his thoughts
on how large a carbon credit is needed to drive this "revolution"?

back to the first days of "stoves" (and a bit earlier on "bioenergy").
However, the sequestration aspects only go back 4-5 years.  The topic is
only recently taking off - as the soils (rather than climate) aspects  are
beginning to excite soil scientists.

in a month) to hear all stove-list members' views on my predicted switch in
charcoal use - either through the list or off-list.  The recent other
correspondence with Crispin on local "woodlots" is also pertinent to this
topic. Thanks in advance for anything (including charcoal production and/or
sales costs in your own part of the world.)

of getting the "terrapreta" discussion list going - much as he has done for
"stoves".    Tom - many thanks!
