Another mention of ozone--did you ever see a rectifier tube that was filled with ozone at work?--a beautiful purple glow inside the tube (no filiament, just cathode, plate (anode), and ozone.

No, but the corona wires inside the copiers I used to work on had a purple glow around them while energized, interesting to see.
The new machines have them pretty well shielded, so the glow isn't as observable as it once was, or not observable at all. Made them harder to diagnose and work on.

Never cared for Hendrix, thought it was so much noise, but WOW, what kind of rock/mineral is that? Is it under UV light (I suspect it is) or does it always look like that?
And if it always looks like that, is it safe?
Please note that in my most recent post there was a brief railroad mention.
The rock is NOT under UV light, just normal room lighting. NO it is not safe. I wouldn't recommend licking it! ( Geologists lick rocks all the time), also don't sprinkle on your cereal. It's safe as stored and handled.
It is stored away, wrapped in lead in a lead lined suitcase sealed in a lead lined barrel 30 feet up by an exhaust fan which vents out any radon gas. It is secretly under care by 2 people. The room is massive and is specially built for storage of radioactive core samples with prism stations for continuous monitoring.
We open 'er up once a year to show new students. We give ourselves less than a minute, more like 20 seconds.
It comes from one of our Uranium Mines from years ago.
Except for the third eye I've acquired in the back of my head I'm fine!
There was an in depth discussion on this maybe 2 years ago on String Lining. Also look up Gabon Reactors.
Yikes! Goes without saying, you be careful, or you'll be riding the "Night Train" sooner than you should! (Railroad reference.)
On the other hand, I suppose that third eye in the back of your head comes in handing for making sure your students aren't goofing off!
As long as you limit exposure, and don't play with that stuff a-la Louis Slotin, you should be fine. An amazing sight to be sure!

Here's a railroad related question. Mooring buoys: I know of nowhere around here where they are used, but from what I've read, they're quite common in New England. I read sometime ago that someone got some old locomotive wheels to use as an anchor for a mooring buoy. Have you heard of that, and if so, is it a common practice?

Never heard about that.

I thought that was mercury vapor, not ozone. All the oxygen would have been gettered (in a glass-envelope tube) long before significant power was applied across it, or so I would think.
Fixed mercury-pool rectifiers, like the ones on the original 3000V Lackawanna electrification circa 1928, may have had some air inside the tank to be excited during arc conduction. As the punchline went in a less PC age: "i don't know,,, I never looked."
You may be right; the rectifier was an OZ-4--and that was about 70 years ago. I used it in a power supply that I built to run an amplifier that I built. I also used a rectifier which had a 5 volt filament, which simply had a slight red glow.
Is this just me? Often, here on the phone, on this forum, in the little boxes at the bottom with links to other pages in the thread, I will get these numerals:
-1, 0, 1, 2, 3
etc.
Just sometimes, not all the time.

It's a software glitch. I get it too. Only seems to do it on page 5.
Overmod - I updated Firefox and now I have the PM problems too. Sigh.

I think it's called the Page 6 glitch. On the next page, the numbering will go back to normal. It's very aggravating if you are trying to find a posting on the previous page.

I asked my doctor if I gave up delicious food and all alcohol, would I live longer? He said, "No, but it will seem longer."
After 34 days, our sailing trip is over. It was a great one, despite our engine incident. Sleeping tonite on our mooring, driving home tomorrow. Hoping 6-8 auto races that were supposed to record while we were away actually in fact did. Car racing (F1 and IndyCar) is my favorite sport, and in anticipation of watching theses races, I have not looked at any racing news in over a month. (But I did hear about the Dale, Jr. plane crash, and miraculous outcome.) Technology can be great: I can now go back in time and catch up on my races.
Sans TV and movies, you folks have been a great source of entertainment.
Thanks for sharing your trip with us.
@Miningman, do you know what the name of the beautiful, flourescent and radioactive mineral is? I could not track it down definitively.

Pitchblende.
The sample and the mined orebody came from the Sue C Pit located in the Athabasca Basin here in Northern Saskatchewan.
There were many seperate lenses of ore composed of fragments of Quartz-cordierite-garnet gneiss supported by pitchblende.
These occurred as very dark bands and easy to distinguish the ore from the waste rock.
I have attached the geological report of the Sue C Pit
It is good reading and loaded with information.
See Minerology starting on page 12. The sample came from the massive type occurance as described on page 15.
