Music Is the Weapon of the Future.

The setup is cheap and can be made with parts easily found online. But the system does have one giant hitch. Because sound is a pressure wave that travels through air, it won’t work where there isn’t any, like on the moon. And it can’t generate enough force to counteract static cling in the thin, low-pressure Martian atmosphere. To work, the dust buster needs to be sealed in an enclosed, pressurized space station.
Which means it can't be used to keep dust off of solar panels on Mars, or on the Moon, or in space, because there will be some sort of window to keep the air in -- and the dust will accumulate outside of that, not inside.

It seems like massive overkill to clean a computer keyboard.

this video was a bit more interesting. Since the 'Acoustic levitation' wasn't actual levitation but rather pulling against a magnet.

Yeah, levitating sideways is bullshit levitation.

Styrofoam beads, they know where it's at (an inch or so above a speaker)

For a second I thought it was going to about this video and was prepared to rant but it wasn't so... nevermind.

Give me a break, you can clearly see the stick holding that ball up. And the background music is some kind of '70s theremin techno shit.

Sonolevitation in another great video, with metal plates. Interview with the artists explaining it.
