Sound waves used to levitate objects. Amazing acoustic levitation


On the subject of alternative energy, acoustic levitation has to be a viable candidate for the accolade of most amazing alternative technologies.

The video in question was filmed by Dr David Deak back in 1987. David was a former NASA employee. (Boo and hiss I hear you cry out) :-) The purpose of the apparatus; to perform an experiment for ’simulated’ microgravity conditions on Earth.

That being said, the applications for such a device go way beyond trying to understand micro-gravitational environments. The current maximum amount that can be lifted by acoustic levitation is a few kilograms - link.
