A superconductive cable anchored in the Earth carries an electric current of great density. The Earth magnetic field generates Lorentz force which levitates the cable. An elevator attached to the middle of the cable transports cargo. Lightning, wind, and icing can break the cable. Geomagnetic levitation is impracticable for the following reasons:
