This company is proposing a design in which magnets are used to repel the train car away from standard iron railroad tracks, and small side-wheels keep the skids aligned. It doesn't use electromagnetic alternation to drive the car, it's just essentially an ultra-low friction alternative to wheels.

Interesting idea. I'm naturally skeptical, but I find the idea neat. I have no idea how you use passive magnets to create a repulsion force, but as the poets say, "Magnets: how the fuck do they work?"

Yeah, I second all that. I am really curious if either the tech or the use case can be demonstrated, but I appreciate the concept.
