“The End of Wheels: A country or state will ban the use of wheeled vehicles by private consumers on high capacity public roads.”

Levitation can overcome the energy inefficiency, pollution, and mechanical failure issues of wheels and tires. Green imperatives will drive innovation in this area.

Magnetic levitation is currently possible but current techniques depend on generation of large magnetic fields, which have large power and weight requirements.

Developments in manufacturable high temperature superconductivity materials and intelligent electronic control will pave the way for efficient maglev systems built into public road infrastructure.
