I got a pat-down the last time I flew because I didn't think you would need to also remove paper from your pockets. I had my boarding pass folded up in my pocket and they even asked if I had paper in my pockets when I went through the scanner and they saw it, but after I took it out they went for a pat-down and wand anyway.

I once ended up in some bumfuck airport in the outback of Australia, where the friendly security official woman dug through my backpack and found a screwdriver that had been somehow stuck/concealed in the cushioning fabric. My first reaction was surprise and glee that the screwdriver I thought I had lost was finally back, then I realized the backpack had gone through a total of 14 security checkpoints between Germany, Singapore, and Australia on the entirety of that trip.

The last time I flew down to D.C. I forgot to take my work gear out of my backpack. Cleveland TSA let me right through without a second glance, but on the way home the guys in D.C. saw something they needed to check out. I initially thought it would be the random tangled mass of 50' patch cables or my screwdriver, then a few moments later realized I also had a knife in there. The problematic item was my toothpaste. Too large of a container.

I've been on the Channel Tunnel and it is quite airport-like at the terminals. I went though a barrier and ended up at the security check before I realised. It was with horror that I remembered that my case had two 1.5litre bottles of water in them. Horror turned to near-panic as I then discovered that I still had my Swiss Army knife in my pocket. Trembling, I apologetically pointed this out to the security staff, expecting the rubber glove treatment. They smiled, said 'no problem' and waved me and my massive bottles of liquid and sharp object onto the train. Took me quite a while to realise that something is seriously wrong when you've normalised getting treated so badly at a transportation terminal.

Pander posted:PCB is trans-fat free! I like the resistive-grounded Wye power systems when you're at medium voltages like 4160V or 7kV or 14kV. On the transformer you run the neutral to earth via a really big-assed resistor that's sized to handle a thousand amps or so for ten seconds. So if you do have a line-to-ground fault it won't be nearly as spectacular and you should have plenty of time for your overcurrent relay element to assert and shut down the faulted area. With a straight delta system there is no ground reference so if you do have a phase get grounded you need to find and fix it before another phase goes to ground and then you get some real fireworks. Only for medium voltage, though. I don't think you would ever do that on a 600/347, 480/277, or 208/120 low-voltage system.

Pander posted:I mean, how long would a medium voltage ground fault before tripping something upstream? I can't fathom that persisting long enough to cause another phase to ground, but then again I only tend to work on systems that have been competently coordinated. In a delta system, theoretically one phase could be ground faulted indefinitely. That's the whole idea and that made ungrounded systems popular at places like factories and mills where you don't want to shut down unexpectedly. So what happens is you have a ground fault, it's detected, and as soon as you can you find and fix the problem. If a single phase is grounded on an ungrounded system there is some current flow (capacitive coupling) but it's very small. It depends a lot on the fault too - like with one crappy connection you could get a fault on one phase, by with a stalled motor that's badly overloaded and not properly protected/coordinated you could have faults sorta propagate. One phase arcs to ground then suddenly two are all three are blasted. With the resistor grounding system you can put a single current transformer to measure ground current and have that trip the feeder breaker when a significant amount of current starts to flow through the resistor. On a regular grounded and properly coordinated system it would trip pretty quick but there are cases where there still could be damage depending on the impedance in the circuit. So in a grounded system you may have 10,000 amps for a quarter of a second versus 1,000 amps for maybe half or one second where the source transformer secondary has a resistive ground that limits fault current. (EDIT: I mean the neutral of the secondary, wye connection, is connected to earth via a resistor.) Three-Phase fucked around with this message at 04:02 on Jul 7, 2017 |

One time about 10 years ago I got a very puzzled look from the TSA agent watching the X-ray machine. He called someone else over, they discussed for a minute, then asked if they could look in my bag. Turns out there was a paint can opener that I didn't know had been left in there, so I told them they could keep it. They said "No, it's fine. It's not on the list so you can have it on the plane." I had no idea the list was explicit.  I mean, it's basically a flat blade screwdriver, which is on the list, but it isn't so it's cool.

On the way to deploy from Vegas to Killeen, they took my Knipex pliers wrench at McCarran. Overall length of 6.25 inches. Just too long, could've hurt someone with that. On my flight full of soldiers. That are all getting on together. As a unit.

I get funny questions about rocks on a regular basis. Yes, that is a bag of rocks. No, just rocks. Yes, you can search my rocks. They're rocks. Yes, you can swab my rocks for explosives. Seriously, you can do whatever you want to them. They're rocks. Pro-tip though: when you're bringing through certain types of rocks, do not use their technical names. Friend of mine spent about four hours in a TSA backroom because he referred to some volcanic bombs he had in his checked luggage coming back from Hawaii.

Three-Phase posted:Ooh are those the fancy crystal energy rocks that can like balance psychic power and Chee and things like that?! lol The vast majority of Tourmaline is actually jet black (sodium-iron endmember, commonly called schorl) and it's known as a "garbage can" mineral in geoscience. Basically every element in the rock will make its way into the tourmaline, and this can make it fairly useful for determining provenance (pressure/temperature of formation, chronology, fluid composition etc). Please don't lick rocks unless you know what you're doing because sometimes they contain things that don't play well with human biology. And if you do lick a rock and it tastes like watermelon, please see your doctor as you might be having a stroke.

Yes, you can swab my rocks for explosives. Some years ago I got a quantity of fine-grained magnetite. The stuff's great, it's basically like a dry sand version of ferrofluid. (Google "magnetic sand" if you want to see it in action with a magnet.) Anyway, at some point, I showed the stuff to my girlfriend when she came to visit and she fell in love with it. I had plenty so I gave her a jar of it to take home. It occurred to me after I'd dropped her off at the airport that I'd just sent her to the security checkpoint with a fair-sized jar of an unlabeled black powder in her carry-on. The TSA didn't bat an eye and let it right through.

Not 100% of the time, but ever since they stopped doing the V-cut thing, some staff just get lazy and cut the bread completely in half.

Sells them for many times the rocks worth as coffee tables. I live in an area of NE Ohio that's, like, exclusively sandstone. I was at a bonfire once where the host had built a rock wall around the firepit out of local sandstone farmers had been tossing out of their fields. One night he had a particularly hot fire burning, and one of the sandstone chunks cracked and split from the heat. Inside there was a perfect, large, brachiopod fossil. I was amazed (I grew up in SW Ohio where the limestone was full of fossils usually) because I was kind of taught that sandstone almost never contains fossils (at least in this area). Unfortunately, I was too drunk to remember to pick it up and bring it home, and it was lost forever. That's my sandstone story. E: And Three Phase, you're a treasure to this thread.

Think about this: what if they had a thin vertical metal partition between each part of the display? So you could stack packs facing outwards but they would not be in "side by side" contact. My hypothesis is that could dramatically reduce the speed at which that kind of fire would spread through the display for minimal additional cost. Anyone do FDS (fire dynamics simulation)?
