Transportation Systems
Transportation systems in a Celebration Society are, of course, important. As I see it, they need to be reliable, largely automated (excepting slow speed conveyances and walking), pollution free, and quiet.
I imagine curving walkways, divided into sections for slow speed (walking), and medium speed (bikes, scooters).
As I see it, we will likely have elevated train cars with panoramic windows traveling above the treetops for great sightseeing and photography. (There will likely be tour guide apps as well as live guides.) We may use the Skytran system, which offers multiple attractive features
Like spokes in a wheel, the trains would take people in and out of the city center. I also envision a set of concentric, winding canals, with eddy pools where electric gondolas can rest for sightseeing, a picnic, or to embark/debark passengers and cargo.
The canals would be home to beautiful fish, other aquatic life and possibly corals.
I envision the gondolas and trains as being AI-controlled. The distance to any point in the City would never be more than two blocks from some train stop. For people with mobility issues, there would be a network of robotic electric scooters that would transport people those last two blocks upon demand.
For hauling large objects into the City, and for construction of buildings, I imagine there being a small fleet of hydrogen lifted blimps. (There is an invention to make them safe.) The blimps would be equipped with electric winches, and tethered to the ground when helping with construction. They would usually be silent and picturesque–unlike present methods of construction.
Larger, beautifully appointed blimps could offer 6-star “air cruise” accommodations transporting people from one Celebration Society to another. There could also be mile-wide corridors of nature preserve connecting the Cities, with Skytran type elevated travel from point to point. (Thanks to Stephen Belgin for this idea.)
I also envision a network of underground tubes connecting all buildings in a Celebration Society. These would be used to transport smaller resources: electricity, water (fresh, gray and brown), fresh food/packages/materials/parcel, cable internet, and garbage/waste removal for recycling. They would generally be serviced by specialized robot technicians, but be large enough for people to comfortably and safely enter as required.
I see fossil fuel engines as being prohibited except in extraordinary circumstances. I see no conventional cars as being allowed inside a Celebration Society, as there would be no roads suitable for them. Instead, people could garage such cars outside the City walls, driving them between points outside the City as required.
No doubt, others will have improvements to these ideas.
