I loved it when it first came out on Catalyst. See the transcript here. It was great... some good music near the end too... who's the group they play at 8:17?

Also, National Geographic has a bit on it.

National Geographic magazine:

Rough calculations show that "the amount of carbon we can put into the soil is staggering," Woods says. Last year Cornell University soil scientist Johannes Lehmann estimated in Nature that simply converting residues from commercial forestry, fallow farm fields, and annual crops to charcoal could compensate for about a third of U.S. fossil-fuel emissions. Indeed, Lehmann and two colleagues have argued that humankind's use of fossil fuels worldwide could be wholly offset by storing carbon in terra preta nova.

I liked it. It didn't really get interesting until about half way through though.

This is a good video that demonstrates the charcoal retort with experimentation. I still think Turtle has a better design.

I'm not fond of this one at all. It basically is a video showing that anyone can make char and help prevent global warming. Good message, right? Nope. Unfortunately, they start out showing a fire starting in some tall grasses. Then it shows a drum full of what you'd expect to see at the end of a large bonfire party. Basically, it's ash with some small pieces of char intermixed.

(the music sucks too)

This one is great! It's basically an instructional video that describes the process of making char at home using a pit fire and a big metal drum (sealed). The person doing it obviously has a good basic understanding of the science surrounding pyrolysis, physics, and engineering.

Another homemade retort video. Good.

Not recommended. It's a 12 second video scanning several raised beds. (with some hand drumming in the background)

I converted it to mp3 (audio only) which your computer, I'm sure, would play fine. PM your email address to me if you want me to send it to you.

Thanks modest Once downloaded I can view video but it takes 'for ever'
But please send anything you think is good.
I think there were a lot more UTube videos than the ones I mentioned

Broad band soon!!

Thanks for the reviews freeztar
We probably should do this on all Utube stuff

Please PM me for my email address \or check biochar climate change group.

Oh, ok, I thought you were saying the computer was "too slow" to watch them. So, that's good - and good news on the broadband. You'll be all night.

Sounds like Danny Day has two units going up soon.
He must be so busy that he didn't have time to tell us about it

Can I just ask how they gear up the cooker to produce syngas or synfuel? Does cooking up biochar tailored for biochar and energy compromise something at some point? (As opposed to just cooking it up for biochar itself.)

And with these more high tech biochar cookers cooking it all in a low-oxygen environment, does that just involve restricting airflow or involve other gases such as Nitrogen being injected? How expensive is Nitroogen anyway? And why does my mate keep insisting that they'd use Nitrogen?

(I'm from a humanities background and need the tech broken down into English please. )
