Mike, My concern would be tied to ownership. Most crops that generate large piles of "waste" (cocoa nuts palm oil, for example) are also plantation crops that would tend to put up a high barrier to sm

Kim Our feelings entirely at Warm Heart. I once coveted wood vinegar and did everything I could to make it with a TLUD. We couldn't get anything to work well. For example, a retort inside really disru

For someone with the right qualifications and interest, the following jobs are on offer: ADB is hiring 6 short-term (6-12 months) international consultants in support of climate action and related kno

Ron, I think that your review of this somewhat odd paper - if viewed from the perspective of biochar - is altogether too sweet. I have been plugging biochar made in low-rent machines, using low-rent f

Kevin, This is just wonderful news. The three of you deserve our thanks and support. Clement has out done himself and Christa's credibility may impress even consummate politicians. My only concern is

Donna, The size of these actions make them way too small for a Kelpie superkiln. I like the idea of using okra stalks. If they are like ours here, they are big and solid, Good fuel. Let me suggest an

This is fantastic news. Can you please provide some details about the qualities of the cement relative to traditional cement (compression, tensile, etc.) and about production. I don't think that i can

Happy to second that. And there is very good European research on the subject as well as great results from feed companies. Big reductions in methane releases, big increases in milk production and wei

Kevin, This is brilliant, a great variation on the Digital Green approach. Congratulations to both you and Clement. M

Paul, Here is where I think that we routinely shoot ourselves in the foot, demanding more fine distinctions and so more and ever finer measures. I think it was Aristotle who said something to the effe

Great idea, but where's all the saw dust? The only place I see it is at lumber yards where guys are knocking logs down to boards. Everyone I know in places like that burns slabs or forest slash. M

Mike, I think that you have a live one. The problem, apparently, is finding investors with a broad enough vision. A couple of years ago when I was gigging at DMU in Leicester, and the pre-Brexit Brits

I am pleased to announce that the most recent Warm Heart Environmental Blog post features an article by Christa Roth extolling Kevin McLean's and Solar 24's Top-Lit Pile method of making char. Feature

Ron, I would check with Stephan Joseph or Pan GETTING, both experts.

So much for the notion of the stupid Vermont farmer. Why does he understand the relationship between fossil fuel energy and N when no politician I can name is willing to make an issue of it?

Kevin, With your permission, I would like to post Christa's report on the Warm Heart website along with the Solar 24 videos about top down burning. M Michael Shafer www.warmheartworldwide.org www.twit

Ron, I wanted to roll my eyes when I saw the title of this article, but when I saw your notes, I was greatly relieved. Here is something practical. (Much as I dislike stoves in general for being too c
