I realize that you don't want to give an exact location, but can you please say what city or town you are close to?

Just curious. Has anyone thought about how to use the heat from making the biochar for something else? Any heat differential is possibly a source of electricity.

Sounds like a great idea. Cut the price to $250 maybe? Also, some of us are just introverts that learn better hands-on. So, the books are nice, but not super useful. And small groups mean non-overwhelming amounts of people where we can be heard. Just throwing that out there.

I'll put out front that I'm a wannabe permie, currently an apartment dweller dreaming in a soul sucking city.

That being said, I found an interesting article about a NESCOT system developed by Saudi Arabia. Link at the end of the post.

It uses a  closed system thermodynamic cycle with an endothermic reaction mixing ammonium nitrate with water, which provides cooling, then uses solar power to provide the energy to separate them back out.
No electricity required.
Given a warming planet, cooling is going to become more important.

Has anyone else seen this, used it? Or other systems?
