All great to hear. Reports from the South African Forestry Service suggests that the square Kon-Tiki is very awkward to carry up tough slopes and tight trails. You might consider short, narrow designs

Frank, Just a quick comment about a point that you make in passing but that I have to field constantly: what about all the wasted heat? Well, here's the question: Just what are you supposed to do with

If you guys have a tractor, you already have the means to solve the biggest problem, quenching. Carry your burner into the woods, then go back for a tank of water. I say burner because a Kon-tiki won'

Well, Kevin, if my dad were alive, I am sure that he would get a kick out of parcing your equations. Me? Not a chance. On the other hand, I love the observation that cow farts are carbon neutral since

Dear Geoff, This is an interesting take on the whole methane thing. To be honest, it never occurred to me that my troughs and trenches were emitting lots of methane until pushed about this by Hans Pie

Methane point well taken. Sorry, I was thinking entirely in context of another project. I would consider NOx v. N2O, however, since the warming multiple is so big. (The math is in the footnotes, so yo

Paul, I have been corresponding with Hans Pieter Schmidt and others of the biochar "biggies" about a new project involving the counting of small producer biochar in the climate change budget. I have l

Cool. Re the previous,. Although not formally documented as the EU use of biochar in animal feed is, our farmers from many separate and unconnected locations in E Africa report that the addition of sm

I think that all this is very cool. I think that it is also very important not to get hung up about a single aspect of biochar's role in animal feed. I have no idea what kelp or whatever contribute to

Nando, The who will pay question is perhaps the key and goes back to Wayne's observation that cost-benefit is hard to judge. I asked my own question in an effort to determine whether there might be su

Wayne, Many thanks for the information. i am familiar with the mercury studies from efforts to contain mercury pollution from artisanal gold mining in Africa. The question of cost-benefit is always a

Kathleen, Nothing re your question, but a related one: have you found a replacement for cement? I know about using biochar in cement, but the entire process is so energy and carbon intensive (extensiv

There are lots of articles about the effectiveness of biochar as a heavy metal decontaminate (China/cadmium in rice paddies; Europe/lead at brownfields; US/old mine tailings, mercury). i have three qu

So, David, if I read you correctly, the notion is that there is no need to worry because in a complete system of bacteria, the "bad guys" will be reduced in number to such a minority that they will no

Thanks, Mike. This raises an issue that I had never considered, "snippets of DNA." Because we now know that it is possible to make even the nastiest water potable by putting it in a clear bottle and s

And why not? Using a simple trench, they could pyrolyze any available biomass that they could cut and partially dry. Mixed with clay or, better, dried and powdered banana peal, they can make fuel ball

Tom, Thanks for posting this. Hugely important where we are working in Africa. It will be particularly useful convincing the South Africans who for whatever reason seem to be singularity resistant. M

Claudia, Thank you very much for your patient and reasoned reply to my recent impatient and unreasoned rant. Although to my amazement it has elicited a large number of personal emails thanking me for

Tomaso, You are absolutely correct about the potential instability of injected, liquid CO2. I, however, have never considered this a carbon removal technology but only an emissions reduction technolog
