There's also the massive already carved out empty space under it. This park is going to have sooo many secret areas by the time I'm through with it.
Server still down.
So, planned out the basic design of the charging stations.
They will be frame based, so as to allow a tugboat-esque hauling into where they need to be positioned. It also makes it more difficult for accidental removal of material (as frames with covers won't be pulled along by a ship's uncovered frames). There will be multiple colorations, similar to shown, to aid with lining things up; probably not that bright, but similar patterning.
As far as the connector interface, I think I'm going to go with a design like so:
Ship builders are responsible for ensuring ship frames won't run off with part of the cable; so ensure covers are used on ship exteriors. These connectors can connect to up to 4 corresponding connectors on the ship power is being transferred to, though you don't need to use all of them. Ship-side connections can be internal or external, with the station-side pattern continuing without obstructions for at least 4 blocks (at which point the shape may change). Charging stations will have connectors available in all 6 directions with the same pattern.
As for skycity itself, I highly advise against the sort of plot-based construction like is seen in town. I also suggest a sort of 'planned chaos,' where we go for large quantities of relatively small interior spaces all pressed together in a vast, 3-dimensional jumble. Think Hengsha from Deus Ex: Human Revolution.
Think valleys and canyons built out of the city itself, some overlooking open dropoffs all the way to the ground. I would also like a multi-layered approach to it. Generally large, opulent structures on higher areas overlooking the rest of the city; in the pits and chasms overlooking open air, small little places in large quantities. Under the main level of the city, and sort of fading into it at the lower areas, would be a more mechanical, technical feel to it. A sort of maintenance & utilities network. These, as well as downward pinnacles and extensions from the large, opulent structures, would define the underside of the city. And most importantly of all, things need to be well crafted. No more boring, purely rectangular crapshacks; just because it is made out of sandstone doesn't make it any less of an eyesore than if it were made of cobble. Put thought into the structures, what their purpose is, and how they would be designed around that purpose. Rectangles bad; smooth curves good.
