In my idea of a solarpunk future, there's no single right way to do solarpunk. Instead, diverse communities from around the world adopt the name, ideas, or both, and build little nests of self-sustaining revolution tailored to meet the needs of their revolutionaries and specifically target and combat the worst effects of exploitative modernity in their immediate environment. Maybe in Las Vegas that means optimizing efficient use of water, while in New York the top priority is developing institutional solutions to homelessness. That model for solarpunk communities involves a lot of isolation -- and I think that's a good thing, because it puts up resistance against the impulse to try and build a single, coherent, all-encompassing movement that tries to solve all the world's problems all together and at once -- an endeavor that usually results in genocide.
But it also requires connectivity, and working with alternate models for connections that emerge outside modernist, hierarchical institutions could be a big part of building a solarpunk movement, or constellation of movements.
Speaking of which, take this tree:
Solar trees are taking root around the world Sologic’s sustainable eTree provides free electricity, free WiFi and even cool water for you and your pet. Plus, each eTree connects to other eTrees, allowing people across the world to video chat.
It gets water from the city plumbing it's connected to, but in development they did get it to pull water from the air.
This tree, or things like it, represent a kind of solarpunk project I hadn't thought about before -- one not grounded in a specific geographical space, but in a specific technology or endeavor that could help seed, expand or interconnect localized solarpunk communities.
