Very very cool. They asked what it could be used for in the video; I say as an ornament of scientific interest, like the magnetic field levitation devices, that hover globes, they sell all over the place.

[@Loundsify]

really cool, video. I wonder what practical implementations this could be used for?

[@andrewglester7875]

Thanks. Prof Bruce Drinkwater discusses that more in the full podcast which can be found here thecosmicshed.podbean.com/e/the-wrath-of-khan-the-cosmic-shed-live/

Loundsify Iran used TRACTOR BEAMS to successfully bring down 2 Americans high tech. unmanned Drones !! & they did so, without putting a scratch on either one, from 40,000 thousand feet... from what I have learned..... But our Government Controlled MSM won't tell us American people this stuff.... Because our Government is run by Shadow Forces that are War Mongers & Controlled by Zionist Elite Assholios, with an Agenda, so Now IRAN they are the bad guys !?? ( Not Really ) If the Iranians were flying any plane over American Air Space w/o permission, who seriously thinks we WOULDN'T have shot their shit down ?? So now we are being Brainwashed into believing that the Iranians are the new Osama Bin Laden, ( Oooops I meant to say Tim Osmond, CeyeA asset & Bush family friend, who died December 2001) I mean We Just HAVE TO SPREAD DEMOCRACY !! You know, like we did to all those other Countries !! like ......? ............?.......? .........? There's so many I can't think of 1 that we actually Left it BETTER than it was, before we Shocked & Awed all of them !! Wake Up Americans, AL Quada & ISIL- ISIS are ALL US / C eye A created & or Funded groups...Our American Government LOVES war. But KNOW THIS : ALL WARS ARE BANKERS WARS !!!!! THEY FINANCE BOTH SIDES, always have & always will. ( FACT ) Use the web, & turn off your ; TEL A VISION !! read a book, stop falling for all of the MSMs FEAR PORN, which is daily anymore

Why do the crazies capitalise weirdly?

[@fabiocaetanofigueiredo1353]

Awesome! Could a beam pull as well? Or only push?

[@cyber_hacker]

yes it can pull, it pushes to generate high and low pressure zones, the low pressure zones is where the particle will be. slight phase shifts or frequency shifts will change the location of the zones and so pushing or pulling it.

Docs brother?

[@cestarianinhabitant5898]

Star wars, but like, with real life n stuff. Awesome.

Star Trek.

[@davidmalpass7129]

This is the devils work!..............Keep it up dude ;-)

[@jeff-TessAD2022]

Goes without saying then that this could not be used in space - no air. no sound waves.

[@andrewglester7875]

Indeed but as Prof Bruce points out, it could be used by a spacecraft inside the atmosphere of a planet...theoretically.

[@jeff-TessAD2022]

True.

[@OverUnity7734]

And if it can be done with sound waves, why not other waves: electro magnetic waves or light waves.

[@MikeTrieu]

Because photons generally don't have enough mass to be able to affect bulk materials, unlike air molecules. There are such things like solar sails and ion thrusters, but those are quite bulky and/or weak.

[@tonywalker8030]

If you interested in a magnetic tractor beam, let me know.

[@tonywalker8030]

***** it hasn't been invented, "yet"

[@MikeTrieu]

You mean like magnetic levitation? As in maglev? We already do that for high-speed trains and the soon-to-be Hyperloop.

[@davidmalpass7129]

But in theory is it a possibility?

[@yunshuizhongyi]

May I ask if you can provide a production tutorial? Thank you

[@ashadowawhisper]

Youre going to think I'm crazy and I know by science I shouldn't be able to hear anything..... but I can hear it. It is very faint when its facing up but when he started moving the beam around clockwise and anticlockwise it increased in intensity and I could more easily hear it, especially when it was facing directly at the camera......... That should be absolutely impossible. There was a doppler effect as he turned it toward and away from the camera...

[@anti-fz9be]

It's microphone noise

[@dancingdoungnut]

Camera mics or whatever mic they were using can pickup noises not heard to the human ear. That is how many sounds we can’t hear are recorded.

[@renbeedativo748]

Gravity is still present.

[@ChaineYTXF]

But once trapped in the sound field, the device can really "pull", as demonstrated in the second half of the videos, where the device this time is upside down. In this setting, it does fight gravity.

[@johngibbs799]

It's called standing waves . Probably gas fantastic applications . Just needs somebody with imagination. 🥱
