I'm wondering if it's gonna be Trigger again. That's mostly why I bothered with it in the first place. But they tend not to do sequels, so I wouldn't be surprised if it wasn't.
The problem with Solarpunk as a fiction genre is that it's much harder to write than any of the other --punks. Solarpunk has a positive bent to it in comparison to the usual cynical tone that the others have. This makes drama and friction appear to be much less of a problem for the characters in the world.
There is a way to do it, but it's harder because you can't use the same story template that the others use.
In your opinion, what's a good example of a well written Solarpunk story? How about another one that is at least well known in pop culture?
I'd say "Nausicaä of the Valley of the Wind" could be one good example. Perhaps a little more post-apocalyptic, but it's got all the markings of positive change, societal sustainability, and environmentalism, along with futuristic sci-fi world building. Both the anime and manga are fantastic, but I guess not too prominent in Western pop culture.
