Here's the gem of this video, in my opinion:

>"What gases did they choose for the small one? [the smaller plasma globe, with the orange-tipped violet streamers on the right hand side of the screen]
The infrared matches with Argon, while the violet and ultraviolet match with Nitrogen.

They used an Argon-Nitrogen mixture, probably the same as used inside incandescent bulbs; a cheap, easily available gas mixture. They combined the gas with cheap low-iron glass that lets the ultraviolet pass. Not the best design choice! Though it does look pretty pretty!

I'm not sure about the origin of the big UV peak around 308-309nm. [refer to chart in video]

My guess is Hydroxyl (OH - which emits 307 & 309 nm) being generated from water vapor by the Nitrogen plasma. Comment with your guess."

PDS: Here is my problem (and why I posted the above video, and quoted the above subsection specifically):

You see,

"How to generate water (H2O) on the surface of Mars" -- is the problem.

Decomposing this problem, then, we need Oxygen, which Nasa's MOXIE solves (https://en.wikipedia.org/wiki/Mars_Oxygen_ISRU_Experiment).

But we also need Hydrogen.

So the question then becomes "How do we get that Hydrogen?".

Well, as far as I know, to the best of my knowlege, as of the present date, there are no known methods to extract hydrogen from chemical compounds that might be found on Mars (I suppose this could change, if say Oil, a Hydrocarbon, or Ammonia Ice (NH3) were located...)

But, failing the finding of those or some other Hydrogen source, there would be the necessity of somehow manufacturing Hydrogen on Mars.

Now, this leads to an interesting question. Which is:

"How can Hydrogen -- be created from empty Space?"

Hey, if the Universe can create Hydrogen particles from empty space (as it did -- because how else did everything get here?), then there has to be a process for doing that.

Now, pay attention, because here's where things get weird!

Inside of gases and gas mixtures, in this case Argon-Nitrogen, there is empty space! That's because the pressure of a gas is defined as the probability (compare to probabilities in quantum physics!) of for a given unit of space, finding the presence or absence of a particle of the gas there!). Gases move around -- in empty space!

In other words, we've got the empty space component -- that newly created Hydrogen, should it come into being, could exist in, could "glom on to", could intermix with...

So now, here's the thing...

Maybe, just maybe (and feel free to call me a Crackpot!) -- the Hydroxyl -- isn't occurring as a result of water in the atmosphere, perhaps it's being synthesized (albeit in very small quantity!) as a result of the highly ionized plasma fields...

This goes back to the idea of fusion/fission reactions occuring at smaller temperatures and at lower pressures, just relative to scale.

Think of it this way... a fusion and/or fission reaction which is at 1/1,000,000,000 (or less) scale -- is not a bright radioactive explosion -- but rather the dullest of sparks, the dullest of glows inside of a scientist's petri dish, or in this case, an electrified Argon/Nitrogen plasma sphere...

Now (and let's be very clear about this!) -- I'm not saying that the above theorizing is right or correct in any sense!

What I'm saying is:

More experimentation needs to be done in this area.

That is, it would be a great area for those interested -- to do future research in! That's all!

Also, Platinum needs to be explored as an electrode material, because of its known affinity with Hydrogen (read papers on Hydrogen Fuel Cells, etc.)...

(That, and "Yes, I know, I'm a Crackpot!" <g> (as was previously stated on numerous other occasions! <g>))
