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'.
