Solarpunk

I recently started making solarpunk postcards again, and I had a lot of fun with a quick scene of a solarpunk cargo ship (a steel-hulled, four-masted barque) in a storm. I'd like to do more but don't yet have any strong points to make or designs I'm excited to feature.

So what would you like to see? What scene is missing from solarpunk art of humans interacting with oceans, rivers, lakes, canals? What weird idea, or old, practical design should make a comeback?

I can't promise that I'll make everything but I really do try to include as many suggestions as possible.

So far suggestions from reddit and discord have included:

• Showing more of the mooring ropes and foundations festooned with underwater life (perhaps in another storm or low tide?)
• Boats or ships with soft wing sails which are apparently good (in theory) when it comes to performance as they maintain their shape regardless of wind conditions.
• edit to add: a clipper ship

I'll state up front that I'm not a nautical kinda guy. I like to pick up terminology and learn but I've never sailed anything larger than a sunfish and I see the ocean maybe once every five years. So feel free to spell out practical considerations and realism stuff because I probably won't think of it.

And thanks!
