A Different Sort of Mag-Lev, as Demonstrated with Toy Train Set (core77.com)

On Friday, we had a look at a levitating lamp by Ger Jansen, who develops and sells proprietary electromagnetics as Crealev. In the same vein, this video of a toy mag-lev train is not the conventional sort of magnetic levitation train, which uses electromagnets pulsing along a length of rail to compel the train into motion; this one is motorless and the magnetic field is formed using liquid nitrogen, a temperature differential, and a proprietary material that conducts an electric current at super-low temperatures.
