[Stoves] Edinburgh biochar

Andrew: (cc stoves list and adding two biochar lists) 

1.For those not aware of the conference about which Andrew is addressing his remarks, it was covered by live video casting today (and I missed it but will try to listen tomorrow). The full program is at 

http://www.biochar.org.uk/ 

a. For Joannes Lehmann (the opener and longest, I think )

b. For Kelli Roberts: on LCA - #10 talk as an example

I did have to listen to a few ads at first - so don't give up to quickly. 


2. Andrew: Thanks for this first day report. 

Sorry to hear about the misunderstanding on the Anila (and confusion with TLUDs) I have seen others using the Rocket design in a similarly confusing manner.. 

3. Re the laboratory electrically powered kiln - what power level? Is this 10 kg in one batch or several? Do you think there is a way to only use the electricity control at the end of the run (or some other way for all of us to achieve reproducibility also)? 

4. What is the attendance? One view seemed about 100 maybe? 

5. We look forward to your report on day #2.

Subject: [Stoves] Edinburgh biochar 

Just a quick report after the first day, the emphasis is on biochar in soils, rightly so IMO. There is some scepticism about stoves and a lot of misunderstanding. The Anila is shown on a poster session modified with a rocket side feed but the term tlud is bundled in with it and unfortunately the uncontrolability of the anila is assoiciated with tlud, which is quite predictable and constant in its burning. The chap who was distribting anilas has stopped becuase they were not well accepted in India. 

There is an increasing agreement on the need to produce char to a specification to properly relate the effects in growing situations, there was also a warning about the poor replicability of scaling up from pot tirals to filed scale. In order to produce a consistant known specificationchar the UKBRC unit has fabricated a simple elecrically heated pyrolyser with an after burner for offgas able to produce 10s of kg of biochar daily. 

This has largelu been made possible by ongoing donations by a couple, Mr. and Mrs Moss, he a retired IBM exective, who had become aware of climate change from two consecutive visist to Scotts Cabin in the artic and noticed the changes from thaw.
