Greetings and salutations,
The following link http://issuu.com/amakaruk/docs/civilization_starter_kit_-_v.0.01/33 is something that I've just now found, and am thrilled to have done so! Before clicking on the link, give me a moment to explain what it is...
There is a young physicist by the name of Marcin (think Martian) Jakubowski, born in Poland and now residing in Missouri, near KC, who found that despite having completed a PhD, became aware that he was essentially useless because of it. So, he bailed out and purchased a farm in Missouri, bought a tractor with which to farm his land, broke his tractor twice, and decided that he needed to build a better tractor. All of this lead to a profound change in thinking, the creation of an open-source maker movement aimed at enabling locally-based abundance/post-scarcity mentality, and a plethora of open-sourced designs, which I am now presenting to you.
Here's another link - http://opensourceecology.org/wiki/Power_Cube_Design_Rationale that will be of utmost importance to anyone diving into this idea.
The thinking is - take it and run with it!
