Open Source Blueprints for Civilization http://opensourceecology.org/
OSE is currently developing a set of open source blueprints for the Global Village Construction Set (GVCS) – a set of the 50 most important machines that it takes for modern life to exist – everything from a tractor, to an oven, to a circuit maker. In the process of creating the GVCS, OSE intends to develop a modular, scalable platform for documenting and developing open source, libre hardware – including blueprints for both physical artifacts and for related open enterprises.
Some of the open source projects:
Rototiller and Soil Pulverizer
Microhouse
Tractor
