Tractor Beam as an space elevator??

2015 was a very exciting year when it comes to science and technology. One of the things that really got me excited was the invention of the Tractor Beam

A tractor beam is a device with the ability to attract one object to another from a distance.[1] The concept originates in fiction: the term was coined by E. E. Smith (an update of his earlier "attractor beam") in his novel Spacehounds of IPC (1931). Since the 1990s, technology and research has laboured to make it a reality, and have had some success on a microscopic level.[2] Another method to realize tractor beams is based on the use of biaxial birefringent media.[3] Less commonly, a similar beam that repels is called a pressor beam or repulsor beam. Gravity impulse and gravity propulsion beams are traditionally areas of research from fringe physics that coincide with the concepts of tractor and repulsor beams. And see this BBC TV news page for a very small-scale real sonic tractor beam effect.

In 2015, A team of researchers have built the world's first sonic tractor beam that can lift and move objects using sound waves.[39]

Tractor Beam - Wiki

So I was thinking, we have been talking about one of these for years!



What i want to know, is it possible to build a Tractor Beam we can use as a space elevator? wouldnt that be cool?

Of course, in the future we will just build anti gravity ships or something, but we are not quite there yet

What could the reach be of one of these things?

What would it cost to build and maintain a "tractor beam space elevator"?

Could it be done?

Gravity impulse and gravity propulsion beams are traditionally areas of research from fringe physics that coincide with the concepts of tractor and repulser beams.

Tractors and pressers based on gravity are still sic fi, the sonic tractor won't work in vacuum.

Certain oofo sightings include the seeming defiance of gravity, inertia and momentum. So yah, one day.

They won't need any elevators after that. Just turn on the antigrav and ships float. No engines, rotors, props, propellers, jets, chemtrails… lol

No lifts, hoists, scaffolding, cranes, ropes, pullies, petons, parachutes or safety nets.

the future is just around the corner So many possibilities

Guess we could even build pyramids again, if we want to

Meh. How about a gravity dam? No cement, just pressers holding back the water. Or electricity generated by invisible impellers in steam turbines…

How about a roller coaster with no cars and a ten thousand foot free fall?

Ooh ooh, bomb delivery without aircraft? Now theres an application.

Or a bunch of Jessica Biel clones!!!

Ok, maybe that doesn't have much to do with tractor beams. Still relevant IMHO though.

Well, for one thing, this system works on waves of sound.

That is a problem in space, because sound is dependent on a gaseous medium, in order to transmit it. In a vacuum, sound does not travel, because there are too few particles to which to transfer the kinetic energy which creates the sound wave, thus the wave will not propagate, and no sound will issue forth.

This means that any tractor beam to be used in space, will have to use entirely different methods to grasp and manipulate objects.

We both know that this is what it would be used and developed for, eventually making its way to the civilian sector after twenty or thirty years. Sad, but most technological innovation is first evaluated on its military applications.

Hmmmm, I wonder what a full sized one of these, that could lift a platform or a ship, would do birds. Sonic waves aren't often their friends.

Cool invention nonetheless!

Just around the corner.
However, they're still working on how to pave the path from bomb storage to delivery site with their sound system.

Maybe they'll have it play a tune as well.
