Well, in a way amateur radio operators have been doing this for some time now. I was able to transmit 20 watts of power using CW (Morse code) and was picked up 5,590 miles away at a receiving station. Granted, it’s microvolts by the time my signal got that far, but the concept is the same and it does indeed work.

Something really interesting happened to me at <a href="#" class="seekto" data-time="107">1:47</a>. When I first watched it, he talks about how the spark grows but I saw nothing but complete darkness in the tube. When I replayed <a href="#" class="seekto" data-time="107">1:47</a> again, however, I saw the spark grow despite seeing nothing there previously. I knew the video wasn't frozen because I could see the blue part at the left side of the screen still flashing. After a lot of trial and error, it turns out that the sparks are flashing completely in sync with the framerate, and because I was watching the video at 2x speed, KZbin was skipping every other frame, so depending on which frame you start on, you either only see the frames where there are no sparks at all, or only the frames where there are only sparks.

From what I understood is that Tesla wanted the capacitance between the ionosphere and the Earth to form a resonant tank circuit with the tower´s coil. He thought that the same setup with the same resonance frequency anywhere else on Earth would pick up the energy efficiently.

[@PhysicsHack]

Thats exactly what I've read also. Not many people are aware of this detail.

[@user-zn4pw5nk2v]

As a way to leech energy from lightning, yeah maybe, as a transmission carrier, both towers would need to be at the poles to interact with "aurora borealis" or be (~5) hundreds of kilometres high to be inside the ionosphere and at that point just use lasers as energy carrier to send energy over the ground level horizon, because you will have line of sight to half the globe (more like an eight), but why use towers then, when you have satellites flying that high. With some really good targeting computers you can use them as high power relays just as currently we have satellite communication, it does relay power but it is less than the energy lost due to air scattering it and also, a megawatt laser is effectively a point and destroy weapon(if 10W one already is, by burning stuff). Melting buildings one laser width (^3) per minute (could calculate a more precise value knowing 1L warms to boil in 2-4 minutes at 1KW and rock melts at 3000 ⁰c so 1KG of cement in like 6 minutes shorthanding heat loss, reflectivity,thermal capacity difference and air)

The concept of the tesla coil is misunderstood. The atmosphere is a capacitor and the ground is the wire and in a best case scenario the transmitter would not leak any coronal discharge but instead just cause the ions in the atmosphere to oscillate at the frequency of the coil in order for it to be received anywhere on earth. The key is grounding and tuning through capacitance.

Best explanation I've heard! One of Tesla's experiments (if I recall correctly) involved plugging dozens of lightbulbs onto a hillside. With nothing connecting them except dirt.

[@TheSbd13]

The truth!

[@taylorwestmore4664]

Have you read Thomas Bearden's theory on Tesla discovering phase conjugation, also called 4-wave mixing? He describes using the Earth and Ionosphere as a self-pumped phase conjugate mirror. The idea was that in a medium or circuit, 2 equal and opposite incoming waves may provide a "pump" to establish electrical Non-linearity in the medium, like the Earth-ionosphere gap, or between a grounded Tesla coil and the thermoelectric currents in the center of the Earth. If you can phase conjugate ambient waves in the environment you can confine them in the system like a resonant cavity of extremely high Q factor, which is also automatically phase locking. Phase conjugated signals are said to be "time reversed" because the phase angle is rotate 180 degrees and the momentum vector is exactly the opposite vector in space to any incoming waves. So these pairs of waves become locked together between Tesla coil and source, building up over many cycles without dissipating by normal reflection or other distortion. A kind of automatic parametric resonance which can cohere noise signals into power with minimal losses. This could explain Tesla's claims of collecting "radiant energy" from the environment in excess of the energy which was transmitted from his coil.

That's spark gaps, not the Tesla coils themselves. Tesla coils are by themselves just a particular transformer topology, and if _correctly_ used won't throw off any sparks... but most hobby users like them _because_ of the sparks, and those sparks (or more particularly the wideband signals they produce) are the problem.

[@zachcrawford5]

This is an extremely brute force approach to wireless energy transfer and I'm fairly certain it's not what Nikola Tesla had in mind. I think his idea was closer to the idea of using tesla coil like devices to convert electricity to a specific high intensity radio frequency that an antenna could receive and convert back into electricity to power a device (kind of like how a crystal radio is powered) but I think he wanted to use just the right frequency so that it not only resonated with the atmosphere but was also internally reflected by the atmosphere so the transmission wouldn't be impeded by the horizon (and wouldn't be lost to space ethier). He wanted to have many of these devices in specific places around the world and have them synced up in such a way that each device's signal generated constructive interference with the signals of the others, basically converting the entirety of Earth's atmosphere (or at least the troposphere) into a lased radio resonance cavity the anyone, anywhere could siphon power from.

i agree- i think tuning and resonance is a big part of this- like trying to make a motor but you haven't balanced the weight or strength of the magnets- theres alot of efficiency left on the table. If transmission stations and receivers are tuned in a way accounting for distance then transmission rates would be much better. Tesla did in fact create a working implementation of this system but his lab might have been burnt down. His main investor JP Morgan, had just invested millions in conventional electric transmission system. He would have been directly undermining his previous previous investments had he bankrolled Tesla's wireless transmission. in any case its too late now- wireless energy transmission is pretty much impossible while cars are powered by HIGHLY EXPLOSIVE LIQUIDS

Probably won't get any real-world use. The concept is sound, but the economics are just a pipe dream. It essentially isn't useful for anything other than over-the-horizon radar/radio, ionosphere research, demonstrations, and ideas for very different applications. It's too easy to tap into without approval, so you can't use access control to establish the resource stream needed to keep the system running.

One other thing is that arcs waste energy which is why you typically want to try and suppress them when optimizing for wireless power. Next time try using a much higher frequency wile also avoiding sharp spikes

There's that, there's also the possibility of explosion if there are any combustible fumes in the area. As well as the challenge of ensuring that the sparks jump to and from where you want them to.

You're thinking of the lowest frequency Schumann resonance, which I think is supposed to be around 1 Hz. Another floats around 60 Hz, and there are more beyond that. As for the standing waves restricting where you could get power with this, probably so, though given that you'd expect world-wide echoes there might be enough "basal noise" at some frequencies to reduce the effect. Also, as long as you were within 1/2 wavelength of the broadcaster, you would presumably be able to use near-field coupling to get power regardless...

The problem with wireless power transmission is the spread. At further distances, you can only recover the power available from the total area of reception. The radiation pattern does not focus itself toward random receivers. It can be optimized for fixed locations, but ultimately, distance will still affect the recoverable signal. There will be much power loss, and some power unavailable due to lack of coupling, being reflected back into the transmitter. A tuned receiver is just an impedance matching device which transfers the most power possible to a load, but make no mistake, it cannot "suck" more power from an area than is available.

I think it’s such a little amount produced that he’s probably fine. He doesn’t have a filament to heat up and he doesn’t have a great vacuum. At least to my knowledge

[@darklogik69]

Don't forget he was also using the aquifer under the tower as a massive dump (Layden jar) paired with the atmosphere...

[@TheMono25]

What happens if you use a 3D printer inside at vacuum chamber would it affect the 3D print in anyway could it make it stronger

[@vishalpatil-fy2ot]

If Nikola Tesla was funded with money and no one stopped him.He could made it and the world we see today will be at another level. With less harm to earth 🌎. I feel sad that there r few pages in history about him. He is a legend. Today's most of tech r based on his work.

[@ABaumstumpf]

No - cause he WAS funded with money. But he was a tinkerer - he just tried out everything without understanding what those things actually did. Heck - he even claimed electrons were not real despite them having been proven already. "Today's most of tech r based on his work." not even close.

[@allstarwatt7246]

@@ABaumstumpf most of Tesla's ideas were just complete nonsense. Which is why it comes as no surprise that his typical modern day fans tend to be scientifically illiterate idiots.

Thanks for this video

[@JeevanSamagar]

🔥🔥🔥 These fires came while listening 🎧....

[@geodeaholicm4889]

the northern lights displays up in the arctic are a similar variety of phenomena, with the electrons originating from the sun, interacting with the earths' magnetic field, & grounding in the earth. i always wanted to go see those.

One end of the small light bulb was of course connected to the spark coming from the Tesla coil, but to what was the other end of the small light bulb connected? To the ground?

[@MrBrauza]

I thought it would explode phew I'm glad this channel showing us really interesting ideas

[@jerotoro2021]

This is garage scientist, not backyard scientist! No explosions lol.

[@freezinfire]

Ah yes, vacuum tubes. Used to be pretty popular long time ago.

[@jibranbhat8711]

The lightsaber. This channel is so underrated

[@Se7eNiToS]

This is amazing!

[@dasireddysaijoshan6122]

how is the current passing in vaccum, like if there are no air molecules to conduct?

[@MammaOVlogs]

can't wait to get my painting

[@lesimages3dclic]

Wow thanks, it sure reminded me those knowledge acquired at college. Teslas was an awesome man. Oh just a little warning here when you use any high voltage generator that produces ions, they also make lots of ozone (O3) which is very toxic at ground level.

[@ThePinkBinks]

But people love being poisoned for their convenience.

[@fuzedcable5612]

This is really cool! So would this store electricity or simply transfer it? Also, would it increase chance of lighting storms?

[@absalomdraconis]

Mostly transfer, though you could get a _trivial_ storage effect. It would increase the rate of lightning strikes, but _probably_ not significantly increase the total power per storm... probably? Also, individual strikes would probably be weaker, but there would be correspondingly more of them.

[@aurid6838]

i read somewhere that the plan had to do with transmitting power through the earth, not air. i forget the details but seemed more reasonable to me

[@jacobgable3163]

How much voltage did it take to make that work?

[@michaeldaugherty6826]

He wasn’t ever able to tell people how. Lost his funding due to greedy money machines, and was attacked and oppressed by those same people.

[@blizzunt420e]

You should see what MIT did using this tech you take copper coils arranged I think in a square formation but spaced half an inch apart with like an acrylic spacer or some thing nonconductive and you can make a directional antenna essentially and then you can put in a receiving one of those on a bulb very far away and as long as they’re aiming at each other it works the same way

[@markrix]

Neat, counter intuitive, i guessed denser air would provide better medium.

[@weirdsciencetv4999]

At the high vacuum are xrays a concern?

[@matthewgarrison6921]

Please, look into Iron Man 1, the charging tube in "The Cave" he uses is the same exact electrotube concept! Cool!!

[@LiftPizzas]

"It's only 5 inches but if you put it in a tube and pump some air out, it gets longer."

[@agent-33]

Can it extend from receiver to receiver?

[@yashshah3240]

Do a cold welding experiment please !
