I saw the Polish name on that and figured this is an extension of the type of farm innovation you see in Communist countries. Polish farmers were known for home built tractor during the Cold War. Some would occasionally use battlefield salvage parts from WW2.

I just keep thinking this guy reinvented the bobcat tractor, but it is neat to see the work they are doing on the modular system and universal designs for self-build.

The idea of common open source machine plans for "building a civilization" is pretty impressive when you look at what is possible with it. I see the seeds of the body of knowledge needed for space colonization or recovery after a major series of disasters.

Looks like something out of Defiance, which I will definitely be watching tonight on scifi.
