Open Source Ecology is accelerating the growth of the next economy - the Open Source Economy - an economy that optimizes both production and distribution - while promoting environmental regeneration and social justice. We are building the Global Village Construction Set. This is a high-performance, modular, do-it-yourself, low-cost 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.
