Environmental engineer with a masters in renewable powers using the magic powers of permies.com to learn all about the "rocket" technology and innovate with the fellow rocket scientists.
Thank you for that addition Timothy!
I feel joy every time I donate some nitrogen to my compost piles in the garden.
The Humanure Handbook is such a good book, can't recommend it enough. It's also free to read if you want to. So basically no excuse, except not liking Jenkin's humor.
It's a fun, not too long and funny read.
One part is diving a bit too deep into the test results and safety, but I guess that's also very important.
For me it totally got rid of any leftover concerns about using humanure and actually turned it around into a joy every time I empty a bucket or pee on the compost pile.
Hi Ashley,
welcome to Spain! Asturias is breathtaking. My american partner an I met there and absolutely love it, but we ended up living all the way in the south.
I know of the project "El Mandala", close to you guys. They give tons of workshops etc. Also an annual meeting to network in September I think. Check them out, they're nice. https://elmandala.es/
Also we have some other friends that communally bought a big plot of land in the north.
Their project is online at https://proyectotortuga.org/
Also we know another couple of friends that bought a hotel. I asked for their info and their permission to forward it to you.
If you ever make it to the south feel free to PM me and if you want you can come visit.
If that vent is taking the air to other parts of the house maybe
building a quick J-tube rocket with a barrel and a simple mass (or another barrel as a bell)
would be good practice for the BBR build in 2026 and replace the old wood stove without too much cost and work.

Note: To get the result you probably want, (a quote that looks like this:
instead of this:
)
you'll need BB code enabled on your post. This is the default setting, so you probably don't have to do anything. To confirm, look just below the text box where you type your reply. (See next image.) To enable BB code, make sure "Disable BB code in this message" is unchecked.

Mobile View
Mobile view has two option for making a reply:
1. Use the "reply" button
2. Use the "quote" button
The reply button is at the bottom of each topic (thread) on permies.
The quote button appears on each post on permies.
scroll to the bottom to click 'reply' or click 'quote' on the post you wish to reply to
Both the "reply" and "quote" buttons will take you to where you can type in your response. The only difference is that the "quote" button will autofill part of the reply with a quote. If you do not wish to include any or all of the quote, you can simply delete it from your reply.

In all the above cases (both mobile and desktop), once you hit submit, you will see your reply in the thread.
To create a new topic (also called "thread"), all one has to do is press the "new topic" on the forum or on a thread.

Thank you Peter. Very valuable information.
I was thinking that I read that somewhere here a while ago.
So for J-tubes with bells we would simply take the 1st gen bbr ISA and divide it by 2.
And if the core isn’t within a bell the core surface counts as well? And a barrel obviously counts too.
