Little different post than typical but I remember being really excited about their tractor and compressed earth block press a long time ago.
Is this just one of those “never build something you can buy” type efficiency things? I’d love to know if anyone has had any direct involvement or firsthand knowledge.
I’m also interested in this project. Looks like there has been some recent activity: https://www.opensourceecology.org/2024-product-release-of-seed-eco-home-4/
You should contact them about getting involved! I did see they had jobs a while back for a project.
