I imagine a City in which every surface is Stainless Steel or Copper, both highly Machined and Polished.

The City is Smart, and has Auto-Polishers that automatically clean and polish the gleaming City using a Closed Loop Energy System.

The Roads are polished Copper, and the Railcars are Polished Stainless Steel.

There are no "Automobiles" because that would soil my Clean Perfection.

The Entire City is a Music Box glimmering with Old World Richness.

The City is a Single Machine.

You must give up all Computing and Communications Devices in favour of the Smart City's Totally Analog Communications and Data Processing Network.

You must give up your Vehicles because you have Free Public Transportation by Rail, as well as a Personal Railcar you may also use for free.

Your Personal RailCar travels all Rails in the City, to and into the RailSystem of every Building, where it serves as an "Allivator" kind of like the one in "Willy Wonka and the Chocolate Factory."

You can ride your RailCar directly to your Business Office, and it can take you directly back into your Home.

No need to be on the Streets. The Streets are for the Machines, who run the Analog-Mechanical Infrastructure of the Smart City.

This Metrowonder is a Magical Gearbox, and a Metro-Area-Sized Winding Mechanical Pocketwatch.

The Smart City is equipped with Public and Free Mechanical Automations that facilitate every Citizen of the Smart City with a Robust Quality of every item in The Maslow Pyramid of Human Needs.

There is an OuterCity of Factories. Every Part of the Smart City must be periodically disassembled by Autoconstruction Robots and Cleaned/Maintained.

If new parts are required, they are Machined in the Factories of the OuterCity, by Artificial Machinists.

The Smart City eats Copper and Steel.

His name is Charlie.

Charlie is Hungry.

Feed him.
