Anomalocaris Posted October 28, 2015 #1 Share Posted October 28, 2015 Real-Life 'Tractor Beam' Can Levitate Objects Using Sound Waves It may seem straight out of "Star Trek," but it's real: Scientists have created a sonic "tractor beam" that can pull, push and pirouette objects that levitate in thin air.

seeder Posted October 28, 2015 #2 Share Posted October 28, 2015 Star Trek-style tractor beam becomes a reality: Device can lift and move small objects using sound 'holograms' Array of loudspeakers produce an acoustic 'hologram' to hold an object This allows small objects to be lifted, moved, rotated and fitted together Sadly it will not work in space as sound does not travel in a vacuum Instead it may find uses in the electronics industry or in delicate surgery http://www.dailymail...l#ixzz3ps0t2JkE 1 Link to comment Share on other sites More sharing options...

highdesert50 Posted October 28, 2015 #4 Share Posted October 28, 2015 40kHz is at the threshold of a dog's hearing but will certainly annoy cats who have an octave greater hearing capability than dogs. Link to comment Share on other sites More sharing options...

Eternal.Quest.4.Truth Posted October 28, 2015 #6 Share Posted October 28, 2015 This isn't exactly new...acoustic levitation of water droplets has been around for quite some time now. Researchers were able to demonstrate fine-tune movement capabilities as well, by combining droplets of water and coffee grounds (essentially making coffee with sound!) Cool stuff Link to comment Share on other sites More sharing options...

ROGER Posted October 29, 2015 #9 Share Posted October 29, 2015 Since when was a sound wave a beam? My thought as well . Wont work in a vacuum . Limited weight usage . 1 Link to comment Share on other sites More sharing options...
