For anyone who is curious. The two phenomena seen in this video are very different, the first phenomena with the screwdriver is an electric arc with a discharge of air molecules. The second phenomena is a "vacuum arc", caused by field electron emission at the anode and subsequent absorption at the cathode. Electrons are literally "boiled off" at the anode, and will accelerate towards the cathode by the electromagnetic field. Not so sure if I can explain the color, most likely due to iron atoms being reduced and oxidized along the path. When electrons are boiled off at the anode you'll also get gaseous iron ions (Fe+, Fe2+, Fe3+ etc), possibly also variations of Fe- and Fe* (radicals). Iron does have emission spectra at the blue and purple parts of the visible spectrum.

First, there is an error in your comment: i think the electrons are "boiled off" at the cathode, and accelerate towards the anode.And i have a question with this video, the arc did not happen until the pressure is decreased to some value by the pump, why?

Plasma Vacuum It would depend on whether you mean conventional current flow or real current flow. Remember that electrons are negatively charged, so they can only be attracted to a positive electrode (cathode).

Plasma Vacuum It's not that easy, because the terms cathode and anode are defined by the system itself. The cathode is defined as the electrode where conventional current leaves. Conventional current is opposite of real current. Short summary: en.wikipedia.org/wiki/Cathode#Flow_of_electrons

Yesterday I was watching a documentary of a Portuguese real case of one UFO in the 70´s with a Air Force in which the pilot is currently commander,and this video explains much that is not understood in the case.Things sometimes have an explanation, we can not have the technology to do or sufficient scientific knowledge, but if they are possible?yes they are.

Thank you

can some one explain to me what is happening here? I thought (doesn't matter have to be present for photons?) gases are ionized to produce photons when Electric arcs. or is it just the result of leaked/extremely low amount of air molecules ionizing? would this look similar in absolute zero pressure/stray molecules, in general?

amazing video!! I always thought sparks were assisted by presence of air particles providing the necessary conductance to these charges to jump over..it seem from your demonstration that total emptiness of vacuum actually improves its conductivity!!!! This has a lot to say about energy from dark matter or vacuum!! no wonder Tesla had several vacuum tubes in his fuelless car!! the vacuum tubes must have made energy harnessing from the environment 100 times easier!..theres a lot of unknown in vacuum waiting to be discovered!!

wow you make a CRT

Does outside surface of tube or tube itself become increased electron activity area

Nice experiment! I read recently that the resistance of a conductor is reduced in a vacuum. It would be interesting to see how much it effects coil resistance. This may have contributed to the length of the arc.

gracias,,buen canal

if you increase the vacuum to remove all the air, the discharge stops because there is no gas to form plasma. also notice the 2 streams generated by alternating current, negative to positive in both directions separately. don't let the streams cross: that would be bad

Looking very similar to Birkeland currents.

Is that an OBIT?

i thought vaccum didnt conduct electricity because it has not atoms on which the electrons could travel through. Just reading about vaccum arcs, it says the plasma we see comes from the metal ions itself. Would changing the material of the tips change the colour? and what happens if you put an insulator, say a sheet of glass in between of the arc? does it go through as if nothing was there or what? Nice video!

Laharl Krichevskoy What you say is true in complete vacuums, but these are in partial vacuum, the colour of the arc is mostly due to the gas that's present (oxygen/nitrogen). This is how Neon tubes work, they're at very low pressure, much lower than atmospheric. At 1 atmosphere, neon tubes wouldn't conduct

You would find that the reduction of air pressure reduces the voltage needed for arcing. In other words: thinner air has less "insulation" capability. Scientifically: the mean free path length increases when air pressure decreases.

If you leave the vacuum pump on long enough does the arc go out again?

Coolkeys2009 The arc's not going to go out at higher vacuums.

Those violet streamers seen in ozone generators, HV pylons or Tesla coil toroids are called coronal discharge. Basically same thing as St. Elmo's fire. Ions jumping and emitting photons.

Nice demo but I think you are wrong to call this an arc "in the absence of air." Your vacuum pump probably does not produce a very high vacuum - the residual pressure in the jar is probably a few 10s of Torr. This is a low pressure arc - at low air pressure, air is easier to ionize (lower breakdown E field). In a hard vacuum, the gap for an arc would need to be smaller than the 1 atmosphere air pressure gap, not longer.

arent arc´s nothing but superheated gases/air??? ..... how can this be possible ? because of rest air because you cannot create a perfect vakuum on earth just like it exists in space !?!?

Electromagnetic waves in themselves do not generate light, everything is dark in the cosmos and silent, because without an atmosphere there are no sounds. It could be said that the cosmos lights up only when the man appears who knows not only to see these lights but to interpret them.
