If you have the patience to listen he says he was playing with
sympathetic vibration and made a ping pong ball float above a speaker
at 28 000 cycles. Back at work they shredded his documentation and
instructed him to go back to "researching" electromagnetic levitation,
he was instructed not to have any more results because it was a
government funded project. pfff how funny.

Acoustic levitation - Ralph Ring

I've always wondered how much influence anti sound has on the energy
consumption of a motor. Can we also tune sound to get more power out
of a machine? It seems to me that drag could be influenced quite a lot
by how dense the air is. It sounds far fetched but all that research
doesn't seem to mean much to what is possible if they don't share the
results with us?

Spin a rotor at 28 000 cycles? It seems so easy. Wish I had the tools.
lol
