Lawrence,
Thats absolutely not true. Biochar is about making heat from
pyrolysis, heating biomas to get the biomas to off gas, burning in a
non oxygen environment. The heated gasses can then be burned, and the
heat from that be used for things that we need heat for, cooking,
space heating, water heating, running a sterling engine, etc. The
"bad" gases are burned off, and what is left behind is the carbon,
which has a lot of surface area for your soil bacteria and fungi. Its
like an apartment building for mocrorganisms, and greatly aids in
fertility. The carbon applied to the soil is very stable, and will be
effectively removed from the atmosphere for a long time.
We are working on developing a home stove at low cost for familiespermaculture forums http://www.permies.com/permaculture-forums
who burn wood for cooking here in southern Belize. This is an
alternative for rural people who cannot afford the natural
gas/propane/butane/fossil fuel that people in more developed
countries use. We have a design that uses a 55 gallon drum and a
welded old propane tank. Total cost? About USD75, less than the price
of two full tanks of propane, and it gives heat for cooking, has
fairly complete combustion, and leaves us with carbon to bury in the
soil. This is not an industrial byproduct, or a way to make money. It
is a way for small farmers to improve their soils while sequestering
carbon (generated in natural gas/propane/butane/fossil fuel run
stoves, for example), while getting the heat they need to do their
cooking.
Again, I suggest anyone considering the merits, or lack of, of
biochar, to read Albert Bates book, "The Biochar Solution". That is
one way to become an informed person on the subject.

Its all about using an industrial (probably wasteful and polluting
processes) byproduct to create another product to market for high
dollar.
It does not make any sense to char biomass to make charcoal that
then must be pulverized and field spread (often using fossil fuel)
when all that needs to be done is to allow weeds to control weeds,
crimp or roll them to make a semi living mulch that controls weeds,
adds seeds and organic matter to soil to increase OM and eventually
humus while significantly building soil quality and productive
capacity.
Thumbs up for notill agriculture (and minimum till).
