Acoustic Levitation in 3D Space (Video)


http://youtu.be/odJxJRAxdFU

Japanese scientists have been successful in moving an object in a three-dimensional space through a complex system of acoustic levitation, surpassing previous research endeavors that lifted the objects in two dimensions.

So, about that whole levitating large stones with sound "mumbo jumbo" that only nut-jobs believe in...

awkward.

Similar to the vibrations of the speaker making the

substance on the surface bounce, the waves propagating through the air act to "bounce" the suspended objects - but in all directions equally. Thus, there is no net displacement.

I also ran across some other videos

dealing with using resonance as acoustic propulsion which may be interesting when applied to space travel. I say that assuming this is already being done "somewhere out there". What if a craft can resonate itself and just move itself from within rather than from exterior speakers.

The problem one would run into using acoustic propulsion in

space is the lack of a medium to propagate the waves.

For example, you can't hear an explosion in a vacuum.

I went to a physics seminar a few years back where a researcher gave a presentation on trapping and moving microstructures using a focused beam of light. He even had a video from a microscope where he moved around tiny living organisms with the same method without damaging them. I thought that was pretty neat.

Yeah I figured

that's why I thought that having the resonance come from within the craft might work but I'm no expert in any of that and have taken no classes either. There may be something there with light as a propulsion if you could resonate at light's frequency... that might lead to some weird and awesome discoveries.

I don't think that you're far off base...

It may actually be possible to use some type of unbalanced vibration for propulsion.

First, let's consider a more traditional propulsion system - a balloon that develops a hole. Imagine the balloon as a sphere. Inside the balloon there is uniform pressure distributed over the internal surface before the hole is made. Imagine that pressure as little arrows pushing against the interior. With no hole, an arrow on one side is equal and opposite to the corresponding arrow across from it - which results in no net force (all the arrows cancel). Once the hole is made, an arrow is removed. This leaves the arrow across from it unbalanced. That is the arrow that propels the balloon and the reason the balloon will begin to travel in the direction opposite to the hole.

Now, consider a vibrating object such as a jackhammer turned on and just laying on the ground. The vibrations are not balanced which will cause it to move across the ground. In this example, contact with the ground is an important factor in the motion. However, it is not immediately clear to me whether or not an irregularly vibrating object would move (with net translational displacement) on its own if suspended in a zero-gravity environment and not in contact with any other objects (ie a vacuum) or if it would just remain in place and vibrate.

Perhaps, NASA could take one of those vibrating pens to space and try it out.

Hahahahaha!

Vibrating pens! LMAO! Nice one.

All in all, some good stuff to think about here. Thanks for your insights :)

About ten years ago I watched a video by David Copperfield...

his magic videos and specials.

In the behind the scenes extras on the dvd he said 'You wouldn't believe the technology we had to develop for this trick."

I knew then that almost all of his stage magic was advanced technology that had not yet been revealed to the general public. Like floating in mid-air - this explains how he did it.

It is what it is and it ain't what it ain't. Also there's pandas.

What if "magicians" were really government workers

testing new technology on the public to test its effectiveness???

Hey Brother!

Good to see you here.

I caught this video awhile back and it's amazing what is capable in small doses.

Love the idea of displaced gravity due to sound wave frequency disturbance. The overlap of energy is creating a 'negative gravity' node. Brilliant display of the natural forces that flow within and without this meshy space.

Happy New You!

They that give up liberty for security deserve neither.

Happy New NOW, to you, Friend!

Life is so awesome! It's quite funny to look back at all the tv I used to watch, the video games I used to play, and to see those "interests" become dull filler, at best, when REALITY is full of such amazing wonder!

2014 is going to be a wild ride!
