I'd googled it, it was Jean-Pierre Petit MHD propulsion system, a vacuum thrust propulsion system that decomposes air in the desired direction of travel. When I'd read about it years ago it suggested that the vacuum created would only be a couple of milimetres thick and that atmospheric air pressure would push the craft from below to fill the ever ending void of air. My reasoning was that air pressure from above would be enough to fill the void therefore it wouldn't work.
Isn't there a french guy that came up with a vacuum thrust propulsion system similar to this process that decomposes air in the desired direction of travel. Apparently magnetic fields on the perimeter of the disc controlled the direction of flight. I'd read about it ages ago and thought it was all shit. The top of the disc was I think constructed of Teflon and the craft supposedly used microwaves or excellerated electrons in a vacuum
Do you think the cathode ray propulsion legend is a myth?

Oh that's cool, I'm currently at Bellevue College, just a few minutes from you and have a stainless UHV system for 70KeV D-D neutron generation and always wondered but was never sure what caused this effect within the chamber. This seems to works best with more reactive metals and the effect I was seeing in my system was likely from the outgassy (non-stainless) contact and connections I had on the HV lines like silver and tungsten. Regardless, that's very cool, thanks!
@U235hexafluoridedude Actually the effect is harnessed in professional sputter-ion pumps for UHV systems where turbopumps can't reach, 10e-9 Torr and below. I wanted to see if Tesla could easily have observed it accidentally and perhaps early-on harnessed this to achieve high vac needed for X-ray tubes, even before any others designed pumps to reach those values. No good explanation for Tesla's pre-Roentgen 1895 x-ray shadowgraph of a human foot inside a shoe, recovered from March 1895 lab fire
@teslaandlyne Plasma turns the oxygen in the air into aluminum oxide. Maybe the nitrogen gets turned into aluminum nitride. Also, high voltage drives individual air molecules into the metal surface. So even argon or helium pressure might start dropping.

@conundrum2007, lots of things to try. Imagine tiny vac chamber (or DIY vacuum tube) exhausted by a stack of alternating plates, like a capacitor stack w/plasma dielectric. Also see the Shawn Carlson version in SciAm: gas scavanged up by zeolite cooled with liquid nitrogen. Maybe plasma against Al powder from art store does better? Large surface area. Buy a Hastings gauge tube and meter.
A great video which inspired me to try this for myself. I used a sort of home-brew CDI circuit to produce around 120 sparks per second. Two aluminum electrodes fitted into a 3 mm I.D. 20 cms long glass tube would happily pump around 4 cms of coloured water into the tube in less than an hour.
However it would never do any better than to fill the tube to about one fifth of its total height with H2O which seems to imply its only the oxygen thats being converted to Oxides. Still great fun :-)
@M0AYF VERY COOL. Ozone appears above a certain e-field threshold, nitrogen compounds at higher field. So O2 should trap first. At some low voltages the N2 pressure wouldn't change at all. Also I've wondered how much the initial Al2O3 layer slows the rate. Perhaps initially sand Al surface under dry N2? Real ion pumps designed to use ion beams, plasma never touches metal, otherwise surface is etched by 'plasma polishing' and gas released again. To try: layer of fine metal mesh above plate
Many thanks for your response and for taking the time to explain whats happening. I now have a much better understanding of Ion-pumps. No doubt I will come back to this again in the future but next time I may try higher energy levels to see if I can pump some of the other gasses.
That's the stupid autofocus. It goes fuzzy on all the closeups in this vid. No fixed-focus allowed during macro mode. But the radio wave impulses from the tesla coil are showing up on the sound track.
Wasn't expecting it to work, seemed like one of Tesla's more silly ideas. But that was awesome. I especially like your nifty little hand held Tesla coil. Favourited.
It's not the current that does it, it's the high-voltage plasma. Plasma is chemically reactive.
All the oxygen in the air gets slowly converted into oxidized aluminum, a white solid powder. The nitrogen in the air gets converted into aluminum nitride, also a solid. The remaining few percent of Argon might be left behind. Or maybe the high voltage will charge up the argon atoms (create ions,) then impact them with the aluminum so they burrow inside it.
It shows how Tesla could make x-rays in 1892, years before other physicists could reach that hard vacuum.
> COIL ....homemade?
Nope, that's a "vacuum tester" Tesla coil, costs around $180 new, see the vid text caption. I got mine on eBay for $30. Some of those are very old and not reliable (like from pre-1920s.) Old ones are smooth, or have large flat facets. Buy the later-model ones with the close parallel ridges on half the bakelite handle, called "BD-10" type.
Tesla's "death ray" was published in the 1980s. Plans depict a giant VandeGraaff machine with a belt of charged air, (pumped by a Tesla turbine of course.) The sphere was covered with glass/vacuum insulated bumps.
Inside the sphere was a many MeV particle accelerator in vacuum which launched mercury atomic clusters (nano-droplets) through the center of a multi-stage aspirator pump. In 1930s NT claimed building a successful prototype. I've not heard of anyone trying this.
Yep. They produce "static" sparks, can be painful, but no visible blisters. Just steer clear of using the narrow glass urethral probe from Violet Ray quack medical kits. Ouch.

Yep. Tesla's 1892 lecture describes the phenomenon, and uses it to pump down a cold-cathode x-ray tube. But the guy was too secretive and didn't let on what he was actually doing. Modern ion pumps use magnets and screens to pump much harder vacuums than this simple version.
interesting because the device which reduce the racket this used a low profile alco permanent magnet which were separated and dialed away from the the plate... noise reduced light increased... M.J.H.
Don't use a jackhammer, when jewelers screwdrivers are the best tool.
Hobbyists who are trapped in the "two-meter sparks" mindset won't have as much fun. Gotta experiment with these little girly-man handheld coils. Playing with these effects is like playing with film plates and uranium ore. You never know whic odd phenomena observed is going to end up with trillions of military spending and cities being incinerated.
They still exist as high-volt car ignition, and as the high-volt power supplies in CRT monitors. But their originally they were the first high-wattage radio transmitters. Marconi used Tesla Cois (also called "spark transmitters") to broadcast across the Atlantic, and Marconi's patents were invalidated in 1944 in favor of Tesla's. So, who actually invented radio; the patent thief, or the one who actually came up with tuned high-volt spark transmitters?
No, it was a radio transmitter using a pulsed arc in place of transistors or tubes (since even tubes hadn't been invented yet.) Easily puts out thousands of watts.
A Tesla coil is not really a transformer, since in theory it should step up the voltage perhaps 100X, but in practice the voltage is far higher. It doesn't have a step-up ratio, instead it stores radio energy in an EM resonator. If you keep on pumping in more energy, the voltage keeps growing higher until something breaks down.
Tesla invented the ion pump (discovering the phenomenon before 1892.) He used it to achieve low pressures for x-ray tubes, pressures not attainable by the other pumps of that era. But as with many of his discoveries, he didn't patent it.
you better be getting paid to do this stuff XD REALLY cool! I've never been all that into physics, but this grabs my attention more than the professor ever could!
Note: I didn't take physics class because I can't pay attention that long lol...damn ADHD...
Tesla in the USA invented a huge number of coils, including small handheld coils, and all possible connections of primary/secondary. Oudin in Europe invented a coil with no primary which was a large vertical spiral (like 1ft across, several feet tall.)
Over years people wrongly started calling them by the name "Oudin coil" if they were vertical with high-volt tip. If the coil was horizontal, with two HV ends, people called it "Tesla Coil."
You know, you're right; you can drive this thing with 25 watts. Likely, that little thing he had was only running on, say, 50 watts. The way it works isn't the amount of power, it's the voltage. You can turn 25 watts into five million volts if you know how to do it.
How can this method be used for evacation of roentgen and lenard tube type set ups? What books or referrence material could I be referred that contains this kind of information based on this type of vacuum. Must say amazing and I want to know more!!!
As with diffusion pumps, ion pumps are for high-vac and UHV. But suddenly I got it in my head that it might still work at 1atm. It does, but it's very slow (and best for tiny volumes.)
OTOH, for larger volumes, if you pumped a rough vacuum with a rotary pump, perhaps you could get to the x-ray realm just by running a big glow discharge with a tesla coil for hours. No diff pumps or turbos needed!
> hi would it be able to be done with a jar as the spacer and the lid as the electrode
Yes, but it would be incredibly slow. That thing only worked for very small volumes of vacuum.
Why not a "Tesla Vacuum Pump?" If a jar was full of close-spaced metal plates hooked to a tesla coil, it might pump down much faster. Perhaps use thin glass spacers to prevent direct arcing. Then use plumbing and a short hose to hook that "pump jar" to another empty jar to pump a vacuum.
yea that is real. i read his experiments on making special light bulbs, one was the force of the gases out of the glass making a vaccuum in the bulbs. besides that, he also did ruby lasers, xrays, and led technology. its a great article, he really has given us soooo soooo much technology.
Tesla invented a "health device:" a high-volt coil and a glowing vacuum tube held against the skin. Today these are called "violet ray" or "violet wand" coils. At about the same time, Oudin in France invented a large table-mounted coil for different health purposes.
Tesla didn't take credit for his health devices or patent them, "giving them to mankind" over objections of his partners. Today this sometimes causes confusion: which coils were Tesla's?
> could you ever put this to real use, say, with putting a vacuum on a vacuum tube?
It's already being used, search on "ion pump". But those things are used at ultra-high vacuum. I wanted to see if the pumping effect might even work at 1atm pressure.
> But I mean COULD you take something from 1 atmosphere down to hard vacuum with this?
I'll try that eventually, when I figure out how to measure pressure in tiny volumes. A standard gauge has way too large a volume for such slow pumping.
> oudin coils have one end of the primary and secondary grounded.
Nope, that's a myth. Tesla patented all sorts of coil configurations including the single ground. I've seen people insist that conical coils are "Oudin coils," yet Tesla patented them too. I think the real issue is an old battle between Tesla supporters and Oudin supporters, and they fight over types of coils. The original Oudin coil is a grounded *single* helix with a movable tap that determines "primary" and "secondary."
Well, without going into a battle about this, I'm going to incite one and then, like, run away.
The tesla coils we know of today are of a design perfected by oliver lodge.
Tesla used all sort of weird crap... high pressure spark-discharge tubes filled with nitrogen, carbon wires, carbon toroids, bimetallic electrodes on his spark gaps, and he really did invent oil filled capacitors and litz wire.
No bubbles. Some ink was in the tube at the start, and it immediately started moving in. I expected bubbles, but then again the plasma is between thick slabs of glass and aluminum and could be cooled by conduction. From ion-pump literature, plasma is well known to create low pressure as it converts non-noble gases into solid compounds.
my facts to support this is -that it did not flow immiedatly and you said it was "sucking" the air did go somewhere - we can agree with that... but going somewhere by expanding and then collapsing is what i wonder about. are you sure there were no bubbles in the ink?
part II - but eventually the metal dissapates the heat more than the tesla coil puts out (radiators get more efficient with higher temerature diffarentials)
i thought this was cool till i gave it some real thought. this could really be anything.
Plasmas cause chemical reactions. I expect that the N2 nitrogen molecules and O2 oxygen got split and combined to form solids: aluminum nitride and oxide. The small amount of Argon in air might be left behind... or it might be ionized and get driven down into the metal surface.
> maybe this is a new way to surface harden iron ?
Yeah, or put a silica film onto silicon. Now if a silicon film could be sprayed onto a mandrel, and then exposed to gas and high voltage, you could rotate it and build up sequential layers of oxide or nitride or carbide. It might resemble mylar film, yet be bulletproof and un-creasable.
The plasma is against aluminum on one side and glass on the other. Plasma is chemically active, so the air molecules should combine with the solid surfaces. But glass is relatively inert, so the pumping effect seen is most probably caused by formation of Aluminum Oxide and Aluminum Nitride.
Hey Bill, neat trick! I seem to remember that Tesla used a high voltage to give the highest vacuum for his equipment. Evacuate a glass tube as much as possible with a pump, then run a very high voltage (DC?) to an electrode inside the tube. Let the streamer actually penetrate the glass to an exterior ground. The streamer would make a microscopic molten hole in the glass and simultaneously propel out the last bits of ionized glass. When the voltage was stopped, the tiny hole would self seal.
> The streamer would make a microscopic molten hole in the glass and simultaneously propel out the last bits of ionized gas.
Weird, but check again. Once the hole appears, Tesla says the pressure rises... his point being that it happens slowly, as if "cathode rays" can slow the inrush of air as well as keeping the hole open. The pressure inside a tube with a visible hole should not rise *slowly.* Tesla believed that chunks (we'd say 'atomic clusters') were being flung through the glass.
well i did actually mean a slightly modified experiment so as not to over voltage the dielectric but you say it might work that is good enough for me to try it thank you mr beaty
this is cool , would this work with hdpe ?could this be used to evacuate home made end foil type caps , just make it, ground one terminal, and zap it with a small tesla coil, could it really be that easy !!?
That might work, but only for high-volt capacitors, since initially the dielectric would have to survive tens of KV. If instead the capacitor was first pumped down in a vacuum chamber as the glue seals hardened, internal pressure might be low enough for low-voltage glow discharge. Then just use a solid state high-freq power supply, not a 50,000 volt tesla coil.
another thought arises concerning this ..would you still get the same effect if both terminals were connected to a small tc ?? this would eliminate the stress on the dielectric but would it still pump it out
When I have time, I'll try it out with one of those tiny 1500V fluorescent tube drivers. I suspect that the volts would be too low to get any corona, but that would depend on the thinness of dielectric, which in this case is very thick (1/4" glass mirror)
Hi, I really like your videos. Question about this one though - if the plates get hot when you zap them - at least the top one - wouldn't it expand and create a vacuum too? And then wouldn't the air expand and push the ink back down. Hmm. Thanks again for the cool vids.
You know anything about Dr. Robert Bussard's research in Inertial Electrostatic Confinement fusion? It also goes by the name Polywell Fusion sometimes?
It's not his, as far as I know. It's Farnsworth's, from the 1950s. It was ridiculed as fringe science for decades, but then a couple of Tesla Coil hobbyists built one in the early 1990s and got the ball rolling. It still remained ridiculed fringe-science though, until they started injecting Deuterium and detecting neutron output. Search on "+fusor +bussard" or "farnsworth fusor" to find all sorts of hobbyist sites.

A Tesla coil is not really a transformer, since in theory it should step up the voltage perhaps 100X, but in practice the voltage is far higher. It doesn't have a step-up ratio, instead it stores radio energy in an EM resonator. If you keep on pumping in more energy, the voltage keeps growing higher until something breaks down.

Tesla invented the ion pump (discovering the phenomenon before 1892.) He used it to achieve low pressures for x-ray tubes, pressures not attainable by the other pumps of that era. But as with many of his discoveries, he didn't patent it.

> an Oudin coil?
Tesla in the USA invented a huge number of coils, including small handheld coils, and all possible connections of primary/secondary. Oudin in Europe invented a coil with no primary which was a large vertical spiral (like 1ft across, several feet tall.)
Over years people wrongly started calling them by the name "Oudin coil" if they were vertical with high-volt tip. If the coil was horizontal, with two HV ends, people called it "Tesla Coil."

As with diffusion pumps, ion pumps are for high-vac and UHV. But suddenly I got it in my head that it might still work at 1atm. It does, but it's very slow (and best for tiny volumes.)
OTOH, for larger volumes, if you pumped a rough vacuum with a rotary pump, perhaps you could get to the x-ray realm just by running a big glow discharge with a tesla coil for hours. No diff pumps or turbos needed!

Yes, but it would be incredibly slow. That thing only worked for very small volumes of vacuum.
Why not a "Tesla Vacuum Pump?" If a jar was full of close-spaced metal plates hooked to a tesla coil, it might pump down much faster. Perhaps use thin glass spacers to prevent direct arcing. Then use plumbing and a short hose to hook that "pump jar" to another empty jar to pump a vacuum.

Tesla invented a "health device:" a high-volt coil and a glowing vacuum tube held against the skin. Today these are called "violet ray" or "violet wand" coils. At about the same time, Oudin in France invented a large table-mounted coil for different health purposes.
Tesla didn't take credit for his health devices or patent them, "giving them to mankind" over objections of his partners. Today this sometimes causes confusion: which coils were Tesla's?

It's already being used, search on "ion pump". But those things are used at ultra-high vacuum. I wanted to see if the pumping effect might even work at 1atm pressure.

I'll try that eventually, when I figure out how to measure pressure in tiny volumes. A standard gauge has way too large a volume for such slow pumping.
wbeaty 4 years ago
an oudin coil is similar to what has today become known as the tesla coil.
The only real difference is the fact that oudin coils have one end of the primary and secondary grounded.
RotogenRay 4 years ago
> oudin coils have one end of the primary and secondary grounded.
Nope, that's a myth. Tesla patented all sorts of coil configurations including the single ground. I've seen people insist that conical coils are "Oudin coils," yet Tesla patented them too. I think the real issue is an old battle between Tesla supporters and Oudin supporters, and they fight over types of coils. The original Oudin coil is a grounded *single* helix with a movable tap that determines "primary" and "secondary."
wbeaty 4 years ago
Well, without going into a battle about this, I'm going to incite one and then, like, run away.
The tesla coils we know of today are of a design perfected by oliver lodge.
Tesla used all sort of weird crap... high pressure spark-discharge tubes filled with nitrogen, carbon wires, carbon toroids, bimetallic electrodes on his spark gaps, and he really did invent oil filled capacitors and litz wire.

> are you sure there were no bubbles in the ink?
No bubbles. Some ink was in the tube at the start, and it immediately started moving in. I expected bubbles, but then again the plasma is between thick slabs of glass and aluminum and could be cooled by conduction. From ion-pump literature, plasma is well known to create low pressure as it converts non-noble gases into solid compounds.
wbeaty 4 years ago
my facts to support this is -that it did not flow immiedatly and you said it was "sucking" the air did go somewhere - we can agree with that... but going somewhere by expanding and then collapsing is what i wonder about. are you sure there were no bubbles in the ink?
orionlion82 4 years ago
i looked at this again...
you mentioned heating it up to drive the ink out.
couldnt you cool it and draw a vacuum with an icecube? liquid nitrogen, dry ice and supercool it?
or how about this? heat it up before you connect it to the ink.
as it cools to room temperature it will draw a vaccum. OR the tesla coil-outputs energy as heat. drives the air out like blowing into a straw,
orionlion82 4 years ago
part II - but eventually the metal dissapates the heat more than the tesla coil puts out (radiators get more efficient with higher temerature diffarentials)
i thought this was cool till i gave it some real thought. this could really be anything.
orionlion82 4 years ago
> where did the air in the chamber go?
Plasmas cause chemical reactions. I expect that the N2 nitrogen molecules and O2 oxygen got split and combined to form solids: aluminum nitride and oxide. The small amount of Argon in air might be left behind... or it might be ionized and get driven down into the metal surface.

Yeah, or put a silica film onto silicon. Now if a silicon film could be sprayed onto a mandrel, and then exposed to gas and high voltage, you could rotate it and build up sequential layers of oxide or nitride or carbide. It might resemble mylar film, yet be bulletproof and un-creasable.

The plasma is against aluminum on one side and glass on the other. Plasma is chemically active, so the air molecules should combine with the solid surfaces. But glass is relatively inert, so the pumping effect seen is most probably caused by formation of Aluminum Oxide and Aluminum Nitride.

"the last bits of ionized GAS"
inacave 4 years ago
Hey Bill, neat trick! I seem to remember that Tesla used a high voltage to give the highest vacuum for his equipment. Evacuate a glass tube as much as possible with a pump, then run a very high voltage (DC?) to an electrode inside the tube. Let the streamer actually penetrate the glass to an exterior ground. The streamer would make a microscopic molten hole in the glass and simultaneously propel out the last bits of ionized glass. When the voltage was stopped, the tiny hole would self seal.
inacave 4 years ago
> The streamer would make a microscopic molten hole in the glass and simultaneously propel out the last bits of ionized gas.
Weird, but check again. Once the hole appears, Tesla says the pressure rises... his point being that it happens slowly, as if "cathode rays" can slow the inrush of air as well as keeping the hole open. The pressure inside a tube with a visible hole should not rise *slowly.* Tesla believed that chunks (we'd say 'atomic clusters') were being flung through the glass.

teslaspigeon 4 years ago
That might work, but only for high-volt capacitors, since initially the dielectric would have to survive tens of KV. If instead the capacitor was first pumped down in a vacuum chamber as the glue seals hardened, internal pressure might be low enough for low-voltage glow discharge. Then just use a solid state high-freq power supply, not a 50,000 volt tesla coil.
wbeaty 4 years ago
another thought arises concerning this ..would you still get the same effect if both terminals were connected to a small tc ?? this would eliminate the stress on the dielectric but would it still pump it out
teslaspigeon 4 years ago
When I have time, I'll try it out with one of those tiny 1500V fluorescent tube drivers. I suspect that the volts would be too low to get any corona, but that would depend on the thinness of dielectric, which in this case is very thick (1/4" glass mirror)

Hi, I really like your videos. Question about this one though - if the plates get hot when you zap them - at least the top one - wouldn't it expand and create a vacuum too? And then wouldn't the air expand and push the ink back down. Hmm. Thanks again for the cool vids.

It still remained ridiculed fringe-science though, until they started injecting Deuterium and detecting neutron output.
