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.
It might seem like a bit of a gyp in that the demonstrator compels the train into motion with his hands, but given that the system lacks friction, it wouldn't be difficult to dream something up to start it in motion in a real-world situation: A big-ass fan like they use on those swamp boats, or maybe even a sail or kite. And be sure to check out the twist on the concept that occurs at 4:00.
