Edge Collective

Projects | Guides | Presentations | Research

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 work through donations and via 'pay-as-you-can' arrangements. Cheers!
