Small Animal Levitation

[Dubh Aingeal]

Researchers for at least two decades have used acoustic levitation to

without a container. Wenjun Xie, a materials physicist at Northwestern Polytechnical University in China, has previously used ultrasound fields to levitate globs of iridium and mercury, very heavy materials. Now the scientist has performed the feat with live animals.

From the story:

Xie and his colleagues employed an ultrasound emitter and reflector that generated a sound pressure field between them. The emitter produced roughly 20-millimeter-wavelength sounds, meaning it could in theory levitate objects half that wavelength or less. Apparently the ants, spiders and ladybugs endured the trick just fine, but the fish didn't do so well due to lack of water.

I'm not sure if I'm following this correctly. they want to make stuff levitate through an ultrasound wave barrier so that they don't need metal containers to store stuff anymore?

I'm failing to see the logistical benefit in this system as it appears the emitter system need to be very much larger that the materials being held. I guess if it's refined heavily it could be useful but I'm sure there are some better things to do with levitation devices. I could be wrong...but for storage?

Me see's the government sneaking little tiny cameras over enemey lines someday...even into offices and secret buildings LOOKING FOR THOSE WEAPONS OF MASS DESTRUCTION and watching me poo..... Or masterbate... =(

(sorry I am paranoid)

Or making tiny little bombs someday and making them float wherever they want...assinating one or many....the possibilities are frightening. :erm :fear
