Edge Collective

Projects | Research | Presentations | Guides

Edge Collective is a distributed research, teaching, and facilitation cooperative working to help individuals and communities increase the capacity of their vital food, water, energy, and communications infrastructure to adapt to challenging environments. All of the research, designs, and code that we produce is freely available online. We support our research, projects, and teaching through donations and via 'pay-as-you-can' arrangements.
