I saw an effort at trying to systematize solarpunk elsewhere that felt a bit confused, but it reminded me of this. I’m not typically inclined to try to taxonamize everything, but I’ll admit that the appeal definitely isn’t lost on me. This felt useful.
IDK isn’t it though, the article mentions the movie directly, I’m assuming that’s where they got the “Metropolis” name. I get what you mean by “solar punk in a large city” and how that’s different but, feel the name is confusing in the context of the article.
