An Electromagnetic Vortex Cannon, Finally!

Researchers say they’ve found a way to create a freely propagating vortex ring, like a smoke ring, but with electromagnetic waves. Why does this even matter? What might this discovery be used for? Let’s take a look.

If it wasn’t for her, a lot of these interesting improvements in science would be missed by so many people. I’m really glad you made a video about the topic!

2:00 the small Einstein figurine also blows rings. Neat detail.

[DarkskiesSiren]

This is dope! Which makes me conclude that you have great taste in research developments.

Let me just drop some ideas : revolve the cone so it makes a "wheel" and now we have radial propagating EM vortex. Cut the cone at an angle (similar to how an ellipse can be made in mathematics), link more pulses as they travel and we have them alternate polarities on left and right side and you could accelerate particles, maybe even plasma. Ionize some air and make it move trough a tunnel of EM vortices. Make an "highway" for satellites in a plasma medium in space, etc.

I just love the way the Dolphin was manipulating the bubble rings. Dolphins know stuff....

While developing the commercial application for electrification of industrial burner flames I built a toroidal burner apparatus using high voltage/low amperage DC input. Our test burner apparatus was built with Farraday cage protection to 5MM VDC and variable power supply output capabilities. It demonstrated, depending on polarity, heat rejection from the torroid, and enhanced performance with combustion chemistry variation between NOX and CO. Development was halted as the company focused elsewhere. On an application sharing aspects related to the fluid dynamics functionally shared with combustion yet independent from that business our team demonstrated electrostatic charge aggregation within a liquid fluid medium using a modified Van de Graaf generator for a power source. Our goal was aimed toward power distribution as well as storage and based on the early work done at MIT which my we had researched in works retained at the Hayden Historical Library. We had mathematical support from a team member in Boeing’s wind tunnel program but insufficient capital to advance development.

I suggest reading up on the MARUADER plasma railgun system, it propels a self-confining plasma torus to a substantial percentage of the speed of light. Initial tests were positive, then the whole thing went classified…

The little Einstein figurine on her desk blowing barely noticeable smoke rings is peak German humor.

If it is a way of transmitting donuts over long distances, I'm completely engaged.

[googlesponge]

Sabine, just had wild thought. Could this be a way to manage plasma rings in tokamak reactors?

[sergey]

If this thing beats the divergence characteristics of the Gaussian beam in real life, communication, radar sensing, microscopy and possibly other sectors will get a huge boost.

One of the fastest I've ever clicked on a video... Making stable structures using just energy, is a way towards force fields, flying saucers, etc. May as well explain ball lightning. Finding new ways how Maxwell's equations slay is absolutely huge if true.

[celebratedrazorworks]

U always read my mind.. It is a boundary phenomenon. Field is directly proportionate to locality compression, orientation, & flow.

[barryon]

You had me at "electromagnetic cannon." Though to be fair you would have had me at "pizza" either way.

[fluglust]

Reading the paper I realized, they did not make the doughnut. They reconstructed how the doughnut would have looked like by checking the frequency dependent response from their "cannon". Presumably, they do not have the propert equipment to generate the extremly short pulse which have the required bandwith to create the doughnut.

[carlbrenninkmeijer]

A nice, coherent donutty presentation... seriously, this is so nice , thanks !!

Vortexes have always fascinated me
I made several vortex canons a while back - even added 'smoke' to a few to help visualize the rings - lots of fun, and managed to amaze some friends
The rings we are familiar with occur in fields of particles (air, water)
Sound waves in both cases

A question I have always had is - what are the particles within which electromagnetic waves wave?
A new question I have recently pondered is - what are the particles within which gravitational waves wave?

Back in the old days scientists talked in terms of an aether (a physical field of particles), to explain electromagnetic waves
Many experiments have shed doubt on this theory (and a number of proposed enhancements) for a number of reasons
Recently, some scientists have wondered if the space-time continuum might be a field of physical particles, within which gravitational waves wave


So much to learn ...

[jasonstation]

For half a century I have been fascinated by all things 'vortex'. They're powerful, playful, magical and seem to have a life of their own.

[vinnylamoureux]

I'm an old man who still has an intense curiosity about a wide range of topics. I thoroughly enjoy most of what you produce, and despite my BA in History, I am able to understand most of it. Even though I knew nothing of it before. Good job, Doc. You HAVE found your calling. Keep going, please.

What I love about this channel is that we oscillate between interesting topics, super interesting ones, and mind blowing ones. Never disappointed ❤
