Above, Flaring of Gas from chimney after several hours, this indicates the charcoal making process is near an end.
Below, the chimney is shut down and the gas is forced into the fire box, thus using the flammable gases to heat the kiln.
Now it is possible to cook food, make biochar and produce enough electricity to charge your mobile phone whilst out camping. It could also be very hand to have in the house in case of a power cuts.
The Prize is $25 million and there are 11 finalist of which 3 are Biochar related.
Researchers report that wood-biochar supercapacitors can produce as much power as today's activated-carbon supercapacitors at a fraction of the cost – and with environmentally friendly byproducts.

NUI Galway’s Geo-Environmental Engineering (GENE) Research Group is currently investigating the adsorption properties of biochar and other filter medias in protecting the environment from nutrient losses arisingfrom various Irish industries. Mre to come.....
The biochar trials continue.
First tray with Radish on the LHS is the control and the others have biochar added.
Picture 1 - chopped dry firewood
Picture 2 - biscuit tin in fireplace with lid and 2 holes for wood gas to escape N.B very important to have holes or it could explode. Also wire wrapped around tin to keep lid on and to remove from fire.
Video shows the woodgas escaping and being burnt off. charcoal is made when flames cease to burn, in this case it tuck about 1.5 hours Remove from fire and seal holes with sand or mud to prevent the charcoal reigniting.
Simply grind up to the required size.
I posted a query on the Foras na Gaeilge web site wondering what the irish for biochar would be and i am told it is Bithghualach which roughly translate to 'bio charcoal'.
Now you can have nice cup of tea and some charcoal and they taste nice!
Lawrence D. Hills book 'Month by Month Organic Gardening,The Green Gardeners Calender' first published in 1971 is considered a bible for organic gardeners and growers. It well worth having on ones book shelf as a reference book. The pdf file below is from pages 34 and 35 of 1989 edition and he talks about using wood ash in the chicken house and he goes as far as saying ''It is worth keeping chickens, if you have a wood stove,to get fertilizer". Remember part of the wood ash will be made of carbonized wood ie charcoal.
We all hear how the biochar should be 'precharged' before use, so what better way than to spread biochar in the chicken house. By spreading it under their roost you will get the chicken droppings mixing with the biochar = precharged.
It also helps reduce the ammonia odour associate with chicken houses and it hygienic and the chickens appear to like scratching it.
I will clean this batch (it’s was the waste left over after packing) out this spring and use in my garden. I expect good results as chicken manure has the highest NPK of any domestic animal. Its particularly high in Nitrogen , because chickens don’t excrete urine separately.
Terra preta irish style, it wasn't just going on in the Amazon and maybe some scientist that have an interest in biochar should start looking nearer to home (both here and in Europe) to see how the hills and slopes of mountains in their countries and along the west of Ireland were farmed using the practice of 'Pairing and Burning' the evidence is still there both from a distance as improved lands surrounded by heather land and in the ground as fragments of charcoal. Gerard Madden in his book 'Sliabh Aughty Ramble' also mentions how the heathery land of the Aughty mountains was dug, dried and burned and applied back on the land as a fertilizer.
Be aware that a lot of Charcoal sold in Ireland comes from this end of the world. You decided if this smells sustainable !
Just spotted this Baby Red Squirrel last evening checking out this years supply of seasoned dry hardwood .
Good to see that they are still breeding in this area.
to see how you can help our Red Squirrels.
The University of Limerick biochar trials continue on 2 crops (Radish and Lettuce), 3 soil types and 3 biochars.
Its looking like this will be one of our wettest summers in many years.(june already is the wettest summer on record). One of the consequences of all this heavy rain is water logged soils and leaching of nutrients, which results in poorer growth.
Biochar can alleviate these two issues by improving drainage and slow down the rate of leaching.
Check Ed Revill an organic grower to see what he has to say about Biochar. Also check the link below to get an insight to the world of biochar production whilst you cook and heat water.
Biochar plus now available through the Seed Savers web site.
