An ecological city system is provided including a core structure and a set of circularly arranged structures having various functions surrounding the core. A plurality of radially arranged transportation structures provide transportation between the circularly arranged structures and the core structure. The ecological city system sustains inhabitant life via a closed loop system for maximizing ecological sustainability, ecological harmony, inhabitant safety, and economic performance and efficiency.

Systems and related methods related to structures with large-scale rotatable elements. Some of the present systems comprise: a tower defining a plurality of human-habitable spaces; a tower hub coupled to the tower and having a transverse dimension of at least 50 feet; an observation wheel rotatably coupled to the tower and having a central wheel hub; and one or more bearings disposed between the tower hub and the wheel hub to rotatably support the observation wheel relative to the tower.

The combination parking structure, roadway and train station is a commuter-based system for relieving traffic congestion. The combination parking structure, roadway and train station includes a parking structure having a plurality of levels, at least one roadway, and a train station within the parking structure. A primary entry ramp branches from the at least one roadway, and a plurality of secondary entry ramps each branch from the primary entry ramp. Each secondary entry ramp connects with, and leads into, a corresponding one of the plurality of levels of the parking structure. Similarly, a primary exit ramp feeds into the at least one roadway, and a plurality of secondary exit ramps each connects with, and leads from, a corresponding one of the plurality of levels of the parking structure and feeds into the primary exit ramp. An internal portion of a set of train tracks is located within the parking structure.
