I've been thinking about trying to depict some of the ideas from this conversation: https://slrpnk.net/post/12735795, using a sort of flat, diagram-like style similar to this old photobash:
Though a bit more complex. The obvious answer is 'don't build cities in swamps' but we already have a bunch of them, and though I don't live there I recognize that they have a lot of unique cultural and historical value and are peoples' homes, so I'm interested in what a solarpunk-adapted version of these would look like.
At the same time, I know basically nothing about New Orleans or similar areas, have no background in civil engineering, and no qualifications to make this except for the capability to do so using an old version of GIMP. So I'd absolutely love to identify issues, places to make improvements, and things that are missing now rather than once I've spent days chopping up images and finessing them into something coherent.
So what'd I get wrong? What's unworkable, out of scale, or dangerous? What style of buildings or cultural touchstones would you like to see? What kind of plants are missing?
I appreciate that actionable near term and like to see what you're thinking. My perspective is largely forced by my physical disability; where I am deeply aware of the limitations of the present. While you're seemingly focused on a hope for a better near term, I am looking to a point where problems like mine are not problems at all.
I think you might find this rather interesting about that future: planets are round... /s LOL jk. The roundness from gravity is part of the differentiation process for resources. Planets are truly resource scarce due to differentiation. The vast majority of resources are inaccessible in the center of the planet. This is actually the primary reason we struggle at our present global wealth and scale. The moment humanity has access to space based resources from just a few near earth objects, everything about resources and wealth will be turned on its head. There are near Earth objects that are known to be planetesimal core remnants. These are already concentrated wealth. The USA's space efforts focus on alpha stupidity, but Japan focuses specifically on space based resource extraction and exploration. While the future may seem bleak, and the implications of space based resources and the upheaval of the present systems will inevitably cause chaos, everything about the present will become antiquated within a couple of decades. The move to space based industry will happen astonishingly quickly. The quick increase in wealth will fuel an age of scientific research and development unlike the present. Moving humans into space will require development of closed loop elemental cycles. The overall implications are enormous. We are on the cusp of accessing that future with large reusable rockets. The car was patented in the 1890's by Benz, but it did not reach the poor until the late 1920's when Ford made them cheaply enough to be accessible. Those that think in terms of increasing accessibility are the ones that change eras, or can under the right circumstances.
Anyways, these are the more near term ideas that are the next major stepping stone to the future. Planets are prisons of misery. We are presently still in the stone age; the stone age of silicon.
