The efforts at SeaChar (Seattle Biochar Initiative) produced a 5-gallon (22-liter) TLUD.
"On Saturday, August 1, Seachar hosted Dr. Paul Anderson (Dr. TLUD) for an all-day workshop in the construction of Top-Lit Up Draft (TLUD) cookstoves. The stoves can quickly be constructed from commonly available materials, and produce charcoal while providing heat for cooking (or other uses). Paul Buy Sneakers | Air Max
I am field testing for the 09 corn season with JMU and consultation Dr. Hepperly at Rodale Institute.
Ten research priorities were identified at the IBI conference, The following priorities I hope to address:
• 1- Economy research/market research
• 2- plant+soil research depending on biochar
• 5- field trials
• 8- application to soil (depending on agricultural or other
Planting date: June 24th.
Two split plots , which each are split into a 20% (27 tons/Ac) & 5% (7 tons/Ac) application rates,
All chars soaked in tarps for 1 month, all chars were mixed 1:2 by volume with finished poultry litter compost and roto-tilled to 5 inch depth.
Gasifier Charcoal as a Substitute for Vermiculite in Container Growing Media
Tom Miles, August 22, 2009 P Pine Seedlings in 25% Biochar
Our second trial of biochar as a substitute for vermiculite in container media for growing tree seedling has proved successful. These tests are by a private nursery to determine if charcoal from a gasifier heating system can be used in container growing media.
The second link lists 5 possible policy options, with a 6th in the comments, that might be considered. Note: none mentions biochar, but agreement with more than a few pretty much eliminates all but Biochar. The idea is not to pick winners and losers, nor to tell elected officials what they have to do, and not to give policy staff one word they do not understand but gives them an excuse to walk away from the entire idea.
Third year results: Fourth Corner Nurseries Soil/Biochar Study
Richard Haard, Plant Propogationist, July 31, 2009
This study predates the coining of the term biochar and I claim grandfather rights to use the word charcoal.
Third year results, Fourth Corner Nurseries soil/biochar study
Summer 2009 Biochar plot studyresults are showing some trends I have had difficulty measuring with the last two years of cropping these plots. The use of buckwheat, a short season cover crop plant makes a visual view of performance reflecting nutrition, quite vivid. In spite of the dips in the plots due to deer browse.

Biochar / charcoal can be used for tapping the Nitrogen and other useful elements. Simple urinals are designed http://e-biocharurinals.blogspot.com/ for tapping the nitrogen and other useful elements for using as a soil amending material for improving the quality of the soils, increasing crop production, addressing the global warming by reducing the NOx emissions, avoiding artificial fertilizers, keeping the toilets clean and odor free, etc.
Monbiot says what’s being proposed amounts to “turning the planet’s surface into charcoal”. But is it really? I calculated just how much biochar would really be needed to store all the excess carbon dioxide in the atmosphere…
Energy Cost of Charcoal
Bryce Nordgren, (Rev) March 26, 2009
Because I really had no idea about how much energy it takes to make
charcoal, I made a table from the specs of the Chinese equipment posted by
gordon eliot. Then I calculated the "Energy Cost" of each component in
(MJ/kg). Finally I aggregated the energy costs from the "suggested
charcoal plants" to get an idea of the energy cost of the entire system.
Note that all of their plants use the new high efficiency coal bar
machine. This should represent a best case scenario: maximum rated
charcoal production at rated power. If you make less charcoal and consume
the same power, the energy cost goes up.
Consider this a first step in understanding the energy efficiency of the
entire process. To complete the analysis, we would have to know the energy
content (MJ/kg) of the produced charcoal. The big question is: can you
power a 30kW generator with the syngas in order to take the small charcoal
plant off the grid?
Munda tribals living in parts of Orissa, Jharkhand and West Bengal states, in India, use biochar for increasing the crop production. They mix charcoal with farm yard manure (pellets of small ruminants / cattle dung) and add to the red lateritic soils which are other wise less fertile. They cultivate vegetables and green salad in the well fenced plots of about 1 acre in size. The biochar is mostly a byproduct from the biomass cook stoves in use (most often three stone stoves / simple clay earth stoves). They have access to wood from the jungles, which is used as fuel.
Characteristics and sorption properties of charcoal in soil with a specific study of the charcoal in an arid region soil of Western Australia
Claire Louise McMahon, University of Western Australia,Thesis, 2006
"Charcoal produced during wildfire events represents an important form of long-term Carbon storage in forest ecosystems. Forest management practices, such as salvage logging or thinning without prescribed fire, may reduce soil charcoal content and, thus, long-term Carbon storage in mineral soils.
Charcoal represents an important component of the soil organic matter pool in temperate grasslands and forests. It contributes to the total water-holding capacity, ion exchange complex, and surface area of the soil environment.
Regarding impact of Pottery shards in the soil there were several questions. I had been searching for pottery shards in the agricultural fields and most often and I got to see some pottery shards in the field. Where ever agriculture was the main livelihood, high densities of populations existence, civilization at the helm and space was a constraint, innovations were adopted by humans, and such practices are sustainable even now.

The charcoal and pottery shards are the two most common by-products of human habitats. At least some charcoal / biochar along with ash was contributed by the people living in habitations in the past (see table in the above link). The availability of the quantity of such by-product, ingenious use, management and development are the aspects still to be discovered. If charcoal / pottery shards did not occur in certain areas in spite of human settlements existence, than there must be some reason yet to be discovered. But both charcoal and pottery existence as a result of human activities was beyond history, so there is no reason why these things are not seen.
The fired pottery made up of clay is most popular. Still the poor people in rural villages in parts of India cook in the clay pots. The pots used for drinking water collection is most common, even today millions of pots are produced and used all over India every year, the usage would be more especially during summers. The evaporation of the water from the fine pores of the pot cool the water inside the pot. The temperature would be at least 5 deg centigrade less than the surrounding air temp. The cooling effects would be very high under less relative humidity conditions. The roofs made up of clay tiles also provide cool shelter, and very much useful in the tropics where temperatures are very high during summers. For majority of the main festivals pots or pottery items are used. From Birth to death, for all important occasions pottery items are used.

Charcoal in Container Growing Media
Tom Miles, January 11, 2009
P Pine Grown in Vermiculite (Left) and Charcoal (Right) Media
After visiting Richard Haard and Larry Williams in early 2007 I started discussing the use of charcoal with various nursery growers and researchers in the West. A commercial nursery in California became interested in substituting charcoal for vermiculite in a growing media - soilless substrate - for container grown tree seedlings.
