Yeah it was a pretty horrifying death.

I do like the more Darwin award death video of chinese people kicking their way through a closed elevator door.

It wasn't anything to do with hydraulic pressure - if you look at the second angle, you can see that the cable holding things up appears to be no longer attached to the thing it's supposed to be attached to.

Car wiring is a mess as it is, let's not over-complicate everything because of a few dumbasses who leave their lights on.

A place like Dubai is going to see their buildings lasting hundreds of years after the skyline of New York flattens itself.

In which case the buildings will stay largely intact for thousands of years, right? Give future alien archeologists something neat to look at.

I'm watching Event Horizon and this spaceship is one giant flying OSHA hazard. Giant pits with no railings and the walls covered in spikes, slippery pools of liquid in working spaces, no safety overrides to prevent a crazy or malicious operator from opening the airlocks, insufficient spare carbon dioxide scrubbers, no PPE stations anywhere near the room containing the giant reactor that emits dangerous brain altering radiation.

Also the ship keeps sending workers to a hell dimension.

They build buses with a rigid frame with the expectation that they are a) slow moving and b) way heavier than 95% of everything else on the road. That way when they do crash into a car, they don't deform much and because they have several times the mass, the actual g force to the passengers isn't that great. It's when they hit things with more mass than the bus, like trees, walls, trains etc, that they have serious problems.


Uggghhh there's basically only two scenarios that wearing a ring can gently caress you up in a shop, and they are both horrifying. The first is what could have happened to you, getting caught on something and then degloving or totally removing the finger. And the other is that it conducts enough heat/electricity that it causes serious burns and can't be removed easily/quickly. When I first got into trades, one of my instructors told me about a guy who lost a finger because he was wearing a ring and reflexively grabbed a wrench that had fallen across the posts on a 12V battery. The ring melted instantly from the heat and fused down to the bone. My ring goes into my toolbox in the morning and back on after I'm done washing up at the end of the day (because I'm worried about the pumice in our hand cleaner eroding the soft metal prematurely).

Lol yes. Completely normal. Sometimes we give you drugs during those that speed up your heart and metabolism and everything in order to provoke the SVT which causes our drugs to "wear off" a bit quicker. Then you fidget and we go oh poo poo and give you more.

I think that what they did was tie all the stator leads together (six sets of wires) and applied a high DC voltage between that and the chassis of the motor.

Generally with a successful hi-pot, you get extremely low (like microamps) of current leakage. If there's a problem you'll get much more. The problem with hi-pot (high potential) testing is that if there's a problem the hi-pot test can push the device over-the-edge to complete failure. I think the insulation was so forgone that it failed pretty spectacularly. At places like factories and plants and mills some of these motors have extremely hard lives.

Here's a 15kV spice that was made completely wrong. It failed so badly that it tripped off the hi-pot tester. Remember this isn't like 120V or 240V. This is 15,000 volts so there are things you need to do that are special for that kind of connection that many people aren't educated on.

I love the conversation:
"It [the bad connection being tested] tripped the thermal overload."
"How often does that happen?"
"Never."

Yes, I mentioned laser-cutting of aluminum using an inert air blast in my post. The point was that, unless you have so much power in the beam that the material vaporizes, you still need some kind of additional applied force to remove the molten material (or otherwise separate the pieces) and create the kerf. With a cutting torch it's the pressure of the oxygen blast, with a plasma torch or the laser cannon thing it's compressed air. With that anti-missile laser it's either aerodynamic forces, or maybe ignition of the missile's warhead or fuel.

Shine a 10-kilowatt laser at an empty missile case sitting on the ground a mile away, and it might slowly collapse under its own weight, but it won't be instantly ripped to shreds or anything.

If that cutting laser had no air blast, the metal in the cut zone would just be fusing back together after a few seconds.


I think the point of using the laser is that it's completely non-contact -- not even a ground electrode required -- so that you can chop up radioactive materials without contaminating the cutting equipment.

The internet story: well obviously that clock looked exactly like a bomb because I know nothing at all about improvised explosives and get all my information from the TV show "24". Even though what he did was immediately determined by the police to be harmless, it was still his fault for doing a thing that looks suspicious if you're a moron, and he should have known better than to upset people dumber than himself. Also his dad was angry about the way his kid was treated so he's definitely one of those radicalized jihadist muslims Q.E.D. they were bad from the beginning and The Kid Was No Angel.
