Would anyone be interested in a new mailing list for appropriate technology, a hands-on nuts-and-bolks forum for
inventors, designers, fabricators, experimenters, manufacturers and end users? Discussion could cover
shops, equipment and tooling, materials, supplies, parts and components, the design and engineering process,
tools and equipment needed for various uses on the homestead and the people around the world who need these things.
Marketing could and should also be covered as there are many new and inexpensive opportunities nowadays.
Half of what I do is in that arena, the other half is putting my inventions to work on my farm or in my gardens.
Anyone else interested?
