Open Source Ecology is a network of farmers, engineers, and supporters building the Global Village Construction Set -- a modular, DIY, low-cost, open source, high-performance platform that allows for the easy fabrication of the 50 different industrial machines that it takes to build a small, sustainable civilization with modern comforts.
Their extensive wiki has been facilitating global collaboration on the toolset. They have been 100% crowd funded for the last 4 years.
The aim of the GVCS is to lower the barriers to entry into farming, building, and manufacturing. Its a life-size lego set that could create entire economies, whether in rural Missouri, where the project was founded, or in the developing world.
