[SY] Scientists Levitate Objects With Sound. (VIDEO)

Quote:
Yoichi Ochiai, Takayuki Hoshi and Jun Rekimoto – scientists at the University of Tokyo – have created a way to levitate objects, in a very precise way, using sound.

An ultrasound standing wave is capable of suspending small particles at its sound pressure nodes. This method has been used previously to levitate lightweight particles, small creatures, and water droplets.

The new system uses a three-dimensional array of speakers, allowing for controlled levitation & movement of objects

The best part about this is the potential for some TRULY devastating weaponry. Just give it some time.

By using those ultrasonic waves, you could probably blow some sucker halfway across the world. yessir.gif

Big deal. When I was a kid, I could suspend a piece of paper in the bell of a saxophone.

Of course! With a wide enough spread, this would make an excellent tool for non lethal crowd control.

Not to mention, it might even double as a force field to completely prevent anybody or anything from coming through. An excellent defensive measure.

There's tons of great possibilities. biggrin.gif

Well they already have sound using "weapons" such as LRAD http://defense-update.com/products/l/LRAD.htm
Which uses anyones iPod to focus sound waves to a fine point. It has a number of effects, such as blown out ear drums, to really doing a lot of harm to flesh if at a high enough level.

Shock waves have also been used for decades with normal munitions. Missiles are often detonated a certain feet above a target because the resulting shock wave does more damage than the physical explosion. Impacting on the target or on the ground can have less effect than detonating above the target.

This is impressively awesome to view though. If we can manipulate sounds effectively enough we might see hover devices in our lifetime!
They just need to find a frequency beyond hearing that is useable.

In my mind came an assembly booth that putts together machines and circuit boards with floating parts moved around without arms and lasers doing soldering etc...
Even surgery could be done with it.

Seeing that and thinking weapons...well...w/e rocks your boat...
