I suppose it is possible that some materials could be quite energy
efficient as they are destructed. I wonder if it is theoretically possible
to harness this affect to generate energy from some exotic materials
thereby using sound as a tool to generate energy which could be used to
generate more sound thereby creating a pretty impressive feedback loop.

Theoretically would an ambisonic levitation system be able to lift an
object with large surface area, high rigidity and low mass? For example a
carpet made from layered graphene?

Would it require less energy than an equivalent magnetic levitation system?

I wonder how much graphene is required to support an object with the mass
of a human.
