Simple charcoal kiln
Folke Gunther, April 24, 2008

A wonderfully simple method for making charcoal at home or on the allotment.

"http://picasaweb.google.se/folkeg/TheSimplestOfTheSimple

--

There is a wide demand for charcoal kilns to be used by anybody having an allotment or garden sized plot. The idea of making char of surplus biomass instead of firing it is widely spread in Latin America (and Japan?). Burning the pyrolysis gasses instead of emitting them makes the method comparatively safe, although not efficient regarding their potential utilisation of gasses.

I agree that his is a very small scale method, bu imagine 2 billion people having it, making 1 kg char a week for their lots. That would imply about 0.1 Gt annually, or 5% of what would be necessary to sequester for making a change.

Naturally, this is not the method to save the world from entering a tipping point, but it could well be of some help.

Jim Hansen on our side
Folke Gunther, April 15, 2008

In a recent letter (yesterday), Jim Hansen says:
There is tremendous potential for reducing atmospheric CO2 via reduction of deforestation, improved forestry practices, and improved agricultural practices that increase carbon storage in the soil. If governments were to encourage such practices, rather than the converse, and if coal use were phased out except where the CO2 is captured, it would be possible to literally roll back the net human-made climate forcing to levels below those defining critical tipping points.
We must remember, at the same time, that the ability of the principal CO2 sink, the ocean, to soak up human-made emissions is limited and slow (Figure 1). If we burn most of the available coal (Figure 3) without CO2 capture, even with the lowest estimates of available coal reserves, it will be impractical if not impossible to avoid passing climate tipping points with disastrous consequences.

Jatta Charcoal Retort, The Gambia

Jatta RetortJatta Retort

My retort is in my back yard. It is a drum with a fairly tight lid and a piece of pipe letting volatile gasses take over the initial firing in the firebox underneath. The drum is enclosed in a rock and soil and lime plaster wall. For a quick start I surrounded the drum with small branches or crop waste before covering the top with a scrap iron sheet with a gap for smoke to escape in the beginning. The drum costs money, the rest is labor.

Carbon sequestration for everybody: decrease atmospheric carbon dioxide, earn money and improve the soil
Folke Gunther, Submitted to Energy and Environment, 2007-03-27

Summary:
The easiest way to sequester atmospheric carbon dioxide is to convert plant biomass into charcoal
and bury it in agricultural land. Doing this will open a new way for farmers and laymen to earn
money (from carbon sequestration funds) and improve land fertility. It is also a way to avoid
nutrient loss from land to sea.March 27, 2007

Torrefaction for entrained-flow gasification of biomass

Abstract
A major technical obstacle in entrained-flow gasification of biomass concerns the size reduction and the subsequent pneumatic transport of the biomass powder. The fibrous structure of fresh biomass makes it very difficult and costly to reduce its particle size down to below 500 microns.

Terracarbona.com - A New Website for the Promotion of Biochar Research and Experimentation
Chris Braun. February 27, 2008

A new website for the promotion of biochar research and experiments was born !
http://terracarbona.com

You can there discover several biochar-related projects, most of them still in active development . If you are performing biochar soil amendmend trials yourself, your contribution to CharDB or to the Field Trial Portal would be highly appreciated!
And if you haven't done it so far but would like to start experimenting, you can also find useful resources, links and contacts to help you.

This website is still in its infancy and any constructive comment, critic, question, advice... is very important for further development ! For that you can use the devoted forum:

Thanks for your contribution!

Restoring soil carbon can reverse global warming

Effects of mycorrhizal fungi and biochar 90 Days

Robert Flanagan, Hangzhou Sustainable Agricultural Food & Fuel Enterprise Co., Ltd. (SAFFE), February 15, 2008

Day 90Day 90

Hey Guys, Just got to 90days of my latest biochar trial and wanted some feedback on what data you think I should be taking from this trial? We can clean off the roots and photo as much as possible and do clearly marked side by side photos.

I don't have any funding for this trials so there is a limit on the depth I can go regarding data collection so I'm really looking for a base list. The medium was sterilized subsoil and we used 2Kg soil per tray with three reps of each treatment (I just took the average of each treatment for the attached photo).

Kind Regards, Rob.
