#2That's pretty amazing.

#3I think acoustic levitation is going to be a technology worth watching over the coming years. I'm very curious what could be achieved with application specific speakers designed/built as arrays as opposed to discrete stock speakers assembled into arrays. It could end up being like comparing a matrix of discrete 5mm LEDs to an LED monitor in terms of precision/accuracy and open up a lot of possible applications.

#4What is the point of this? Its still the same amount of force applied to keep the object suspended in air, is it a sterilization thing?

#5Does the actual soundwave itself have an effect on these parts? They mentioned something about a thin layer of lubricant. Wouldn't soundwaves also mess with this layer as well?

#6If they can manipulate multiple objects at a time, this could really speed up PCB pick-and-place operations.

#7Can you theoretically levitate a car with this?

It shouldn't; fluid is an insulator and the lubricant has enough (viscosity? tensile strength? I'm not a materials guy) to adhere to the part in question. The soundwaves must be super high-frequency so they should just get absorbed without displacement.
I'd be curious to see if something like this could succesfully handle an Etch-a-Sketch or Magna-Doodle without ruining the picture though.

#9Does anyone know what limits the real-time calculation of these fields?

In theory but the energy requirements would probably make that infeasible.
