Providing they scale this up a little and add more track, you could shuttle trinkets at high speed from your bedroom to the neighbor’s front door
This is probably not the maglev a lot of people are looking for, but I would expect toy train expos to have a field day with this.
I wonder if a power charging mat, could both power and also act as the repulsed metal layer?
It would need some diodes etc in the charging mat maybe?
Trains thru rocks, makes travelling much faster. Appreciated by all, a power charging mat much needed.
