Grass Tablet Biochar
4 cm Grass Tablets
Household Grill modified with an iCan reactor

The grass tablet biochar (pyrolytic carbon) shown above was made in an iCan TLUD
with a variable speed blower. This charcoal was air quenched and is thus bone dry.
When wet, it is very soft and can be formed to fit a variety of shapes. I have found, for
example, that grass tablet biochar saturated with cold water is effective at reducing the
pain of burns.

The following pages illustrate some of the ways the above biochar was made.
Note: Grass biochar will be ashy as grass has considerably more ash content that
wood

Grass tablets broken into short sections prior to being loaded into the fuel chamber of
the iCan reactor.
These tablets were made from field grass about 3 years ago in Shelburne, VT. Note
that the longest fibers are about the length of the diameter of the tablet. Shorter is
better.
These tablets are about 4 cm in diameter.

VermiChar Eco-fertilizers subsistence Garden

Attached are the trials i did with biochar from rice husks and vermicast. I mixed the two together and filled the containers to become my garden.

Some of the lessons i learned

1. vermicast is highly water soluble and quick releasing than compost. Therefore i had to sprinkle a scoop of the vermicast once every week.

2. The vermi cast - biochar mix need a curing time before it can support the plants. Beneficial microorganisms can help cure the mix.

3. The earthworms take up a considerable amount of nutrients from the compost to become their body tissues.

And then do you think we can use the biochar-vermicast mix into the floating gardens? They are much lighter.

Good luck with your project.

1 The Basic Mechanisms of the Rocket Stove. With the lessons from people like Rok Oblak, Richard Stanley and the Aprovecho Institute the author began learning to build the holey roket stove in his workshop at Daet, Camarines Norte. With sheer perseverance and amidst scarcity, he was able to create several models and delivered skills training to poor people in Camarines Norte, Sorsogon and recently in Bulacan.

2. Among the many feedbacks from the users are the limitation of the holey roket stove in terms of (1) fragility in handling and (2) capacity to receive bigger loads when cooking for bigger occasions and events and for food business. In response, one of the models was picked up for reinforcements.

I recently discovered these aluminum cookpots with stubby rods welded to the bottom to act as fins. These should improve heat transfer to the cookpot.

For those interested in using coconut husk (not shell)
Unprocessed coconut hulls make lousy fuel.
Coconut hull fiber are generally know as coir.
http://en.wikipedia.org/wiki/Coir
It is a big business in India.
http://msme.gov.in/Chapter%206-Eng_200708.pdf
The fibers are processed into mats, carpet backing, potting material, and geotextiles (for erosion control).
On a small scale, the hulls can be soaked in water for at least a month and beaten to break the pith and used as mulch.
The pith leftover from fiber production is known as cocopeat.
http://en.wikipedia.org/wiki/Coco_peat
It is generally a coarse powder. It can apparently be made into fuel pellets for gasifier stoves. See attachments.

From Alexis Belonio:
Good morning!!

Attached are the info on the latest development on rice husk gas stove in India. Just to update you that rice husk gas stove is now being commercialized by Navdurga Metal Industries of India.

From the India Economic Times:

The three-year-old startup based at Faizabad in Uttar Pradesh has created rice husk-powered, smokeless biomass cooking stoves that significantly reduce the cost of household spending on conventional fuel sources such as LPG, electricity, kerosene, wood and wood charcoal. "Rice husks can give about 3,000 kilo calorie of energy, compared with wood that gives between 3,800 and 4,000. These stoves reduce carbon emissions, and cooking costs significantly," said Jaiswal, 31. Nav Durga's first product, aptly named Janta Chulha Smokeless Stove, was launched in 2009 and priced at Rs 500. It has now launched a range under the brand name, Agni, which caters to both domestic and industrial customers. "We currently manufacture up to domestic 10,000 cook stoves and about 50 commercial stoves a month. We want to ramp that up to 20,000 domestic and up to 1,000 commercial stoves soon," Jaiswal said.

According to recent industry data, about 67% of Indian households, adding up to about 166 million households, continue to use solid fuels as their primary source of cooking fuel. While conversion to modern fuels has accelerated in urban areas, rural areas have been slow. Saurabh and the firm's co-founder Arvind Jaiswal, 56, have set up their own distribution and supply chain system. The startup currently has about 50 distributors spread across Uttar Pradesh, Bihar, Assam and Punjab. The company employs about 50, spread across two facilities in Faizabad and Faridabad, in Haryana. "The manufacturing is done by local talent alone," Jaiswal said.

The original news article, and instructions sheets for the stoves are attached as pdf files.
