    The technology is getting there. I forget which company did it, but one has developed an insane magnetic suspension system for automobiles.

    Right now the limiting factor is the energy required, so battery tech is the bottleneck.

    It’s a real shame shipstones haven’t been figured out yet.

      It was Bose. Yes, the premium sound system producers. It never went anywhere, despite being practical magic, because it added around 2,000lbs and cost six figures.

      They also developed a semi-tractor seat using the same sort of voodoo, which is on the aftermarket for around $5k installed.

      For a heavily constrained system like a car’s shock absorbers, couldn’t permanent magnets be used instead of electromagnets?

        I think the main advantage to fixed stiffness springs was that it was controllable. So if it was a fixed strength magnet the advantages over springs is likely limited compared to the cost. Magnetic suspension is cool because it’s an active suspension system.
