Inside the sphere, the city is organized in concentric rings rather than flat grids:
: Integrated flexible organic photovoltaics across the surface turn the entire sphere into a massive solar battery. Sphere-Flying-Cities.rar
: Deflects high-velocity winds and filters intense UV radiation. 2. Propulsion and Levitation Inside the sphere, the city is organized in
: When passing over "Magnetic Highways" (ground-based stations), the cities lock into stable positions using the Meissner effect, allowing for stationary hovering with zero energy expenditure. 3. Vertical Urbanism Inside the sphere
