does this mean supercheap maglev (hyperloop?) is nigh if we put some carefully designed Polymagnets patterns aligned on a track for near-zero power transportation?
or maybe enen railgun in your palm.
- ChuckMcM 11y agoNo, but it does suggest that you could make patterned magnetic rails and riders such that you had a non-contact bearing surface. By patterning the rail and rider with gray codes you could insure that in all orientations they maintained some "push". They would need a machine to pattern the rails though, and it would remain to be seen how durable such a bearing would be, especially if it got too warm.
- jacquesm 11y agoYou'd need a balancing trick besides just the magnets otherwise you'll end up with a positive feedback loop terminating in contact, but there are some interesting ways around this (that you can also 'roll out' to apply linearly): https://en.wikipedia.org/wiki/Electrodynamic_bearing https://en.wikipedia.org/wiki/Electrodynamic_bearing
