Solarpunk is a movement focused on a positive, ecological vision for a future where technology is used for human-centric and ecocentric purposes. It is a literary, artistic and aesthetic sub-genre and is also closely tied to eco-political activism. Solarpunk narratives have a distinctly positive and utopian foundation in contrast to the often dystopian visions found within other "punk" science fiction genres.

The CORRECT definition of flipside:

The "flip side" was originally the term for the B side of a 45 rpm record. Forty or fifty years ago, "single" 45 rpm records would have the title track on Side A and a lesser known track on Side B. You had to flip from Side A to get to the second track, hence the "flipside" of the album.
