Open Source Ecology (OSE) is a network of farmers, engineers, architects and supporters, whose main goal is the eventual manufacturing of the Global Village Construction Set (GVCS). As described by Open Source Ecology "the GVCS is an open technological platform that allows for the easy fabrication of the 50 types of industrial machines that it takes to build a small civilization with modern comforts".[3] Groups in Oberlin, Ohio, Pennsylvania, New York and California are developing blueprints, and building prototypes in order to test them on the Factor e Farm in rural Missouri.[4][5][6] 3D-Print.com reports[7] that OSE has been experimenting with RepRap 3-D printers, as suggested by academics for sustainable development.[8]
