Open Source Ecology is a network of farmers, engineers, and supporters that has been imagining and creating the Global Village Construction Set, an open source, low-cost, high performance technological platform. These DIY-fabricated industrial machines can be used to build a sustainable civilization with modern comforts. The GVCS lowers the barriers to entry into farming, building, and manufacturing. It is a life-size lego-like set of modular tools that can create entire economies.
