A quick one based on u/Sam-Nales’s comment about combining airship mooring masts with screw conveyors/screw elevators similar to those used by grain silos on my last post over on reddit. I talked it over with the folks on the farming community: https://slrpnk.net/post/3643695 and feel like there’s a definite place for grain and silos in a solarpunk world. This was a quick one, the zoomed out scenes often are.
I’m not sure a mooring mast is entirely necessary here, with the big, recently-reaped fields to land on, but perhaps this farm is using a system compatible to other farms nearby who use more agroforestry, and wouldn’t necessarily like having to clear a patch of empty land just for landing airships
It is conceivable that unlike boats, autonomous airships may not need to be super big - they scale linearly. So a continuous swarm of small, lighter than air evacuated diamond foam devices could come, pick up stuff, and depart for local targets or far away targets via the jet stream. That also removes the need for the tower - they could pick stuff up right from the harvester.
Or, combined with the other idea to move the harvester; grain pirates! The small airship swoops down at night and picks up a some strip worth of grain, and is gone in the morning.
Tractor Jack takes to the skies! I love it.
