Re: All the more reason

So, the Tesli sold in California are manufactured within California, and those sold in New Hamster are manufactured there?

And the Self-Driving software installed on Texan Tesli is actually written in Texas with no part copied to, or from other states?

There appears to be an aspect of interstate commerce in play here.

The lies about the capabilities of the software don't stop at any particular state line either, but that probably doesn't count as commerce.

Care to list a part number for such a device?

It's obviously not an off-the-shelf part as you need to have it made to fit where it's supposed to go, but moving parts passing from an atmospheric pressure environment to 400 bar is something that's done in not just a few chemical production processes, for instance.

So, a solved problem.

you want to open it at the surface

Err, you want to open some ventilation port that has a 121.3% proven method against water ingress. The craft is positively buoyant without ballast, but it's not going to stick out of the water high enough that ocean waves aren't going to slosh over it.

Stoneshop
FAIL

You are unlikely to be able to bolt it from both sides as then you need a rotating shaft or a few that can sustain 400 bar pressure

This is an engineering problem. A solved engineering problem.

that you are floating in the middle of nowhere undiscovered and can't get out

The bigger problem is all of the crew getting out before the craft fills with water and returns to the ocean floor. Mind, oceans are rarely dead calm and without waves, plus you have to be sure your hatch is fully above the surface anyway in the first place. And then? Bravo, you're somewhere in a vast and pretty cold ocean without any life support equipment like isolating flotation overalls, locating beacons or whatever else that might help you being rescued instead of merely recovered.

or you are picked up in distress and they can't get in quickly.

The one situation where time might be of the essence is fire, and that would likely have been fatal already if it started while still under water. In every other case a few minutes will hardly make a difference, especially since rescuers on the outside can deploy any tool they have at hand and for instance start by demolishing the viewport dome. That means fresh air, and then time becomes somewhat less of a factor.

Re: Beacon

A ping a minute sounds good enough to me, given the speed at which movement (and indeed, most things) tend to happen under water.

Stoneshop
Mushroom

Re: Lots of things are possible

Even if we locate the sub on the ocean floor now there is no way to get to it

The type of ROVs deployed have manipulator arms and possibly other tools to grab one of the extremities it has (at least a set of legs it rests on while on the launch/recover platform), pull it free and remove the ballast if it's still at depth.

Once topside there should be someone with a big-ass angle grinder cutting off the viewport dome (softest part of the construction I'd expect) once it's secured and sufficiently above the surface. Then the hatch bolts, never mind that that would fsck this techbro's toy beyond repair.

Re: Transponder

Besides, the company themselves are unlikely to be absolute idiots.

... classing agencies only focus on validating the physical vessel. They do not ensure that operators adhere to proper operating procedures and decision-making processes – two areas that are much more important for mitigating risks at sea. The vast majority of marine (and aviation) accidents are a result of operator error, not mechanical failure. As a result, simply focusing on classing the vessel does not address the operational risks.

Adhering to proper operational procedures gets a little difficult the moment you're being squashed by 4km of water column.

Skipping technical certification because you deem proper operational procedures to be sufficient smells very much like techbro arrogance.

Stoneshop

Re: Jerry-riggedness?

The pressure is outside of the vessel, not inside. Its walls are loaded on compression.

Stoneshop

Beacon

The beacon should be external to the pressure vessel, therefore having a gradual increase in pressure anyway.

Also, it should be pinging from the moment it's released from the launch platform so that whatever happens to the sub and the beacon, they'll know where it was when it happened.

Cales, connectors

Cables and connectors should be available from the pump, you should not have to carry your own connector. And 1 or max 2 standards worldwide for all cars

'Pumps' are an antiquated concept. You can find charge points in public and shopping parking lots, for instance. They're very often unattended. They can be as simple as the common home-use charging box with an RFID reader, mounted to a wall. Some provide a socket, some have a fixed cable and connector. For the ones with a Type 2 socket I use the cable that's part of the car's outfit, like the jack and a spare tyre; when the 'pump' has a fixed cable and a Type 2 plug I get out the Type 1 adapter.

Standardize on Type 2? I still need an adapter, and I don't want to gamble on one being available at the 'pump' so I keep one in the car, as I do with the cable and the granny-charger. Standardize on $other_standard? Same. Retrofit all cars to that $other_standard? Surely you're joking, and of course there will now be n+1 connector standards around that must be provided for.

A fan of fans

First case: computer room with six 11/785s, two 8650s, couple of 11/750s and mVAX 2's, and two PDP 11/70s, with their assorted disk and tape units. I happen to be in there when suddenly the soundscape changes, although at first it's not clear what caused it, then it hits me that the low rumble of the aircon is missing. Which means the kit present is adding several tens of kilojoules per second to the room that should be taken out again but aren't. Sprint to the sysadmin pen, and alert those present to the problem. A couple go on a hunt through the offices, seizing whatever air moving equipment they come across, the others start shutting down anything not utterly indispensable,with only a few comms devices and the systems they connect to left running. It's the only time I saw a thermograph needle move.

Second case: small computer room, with not even that much equipment (couple of mid-size Alphas), but it was in a wooden barrack with a black tar-paper roof directly over it. And half the cooling capacity was out of order due to an unfixable pinhole leak. To try and keep sufficient cooling capacity they had installed a pair of garden sprinklers underneath the heat exchanger, and warm summer days required the tap being turned on around 10 o'clock already. Hot summer days would see a double door being opened to the outside, and four large floor-standing fans pointed at it. The tap, and the door when open, could often not be closed before 20:00, which must have been a nice overtime earner for one of the contractors. Suggestions to dump some buckets of white paint on the roof, or put a couple of rolls of reflective bubble foil over it were dismissed with "this is a temporary building" (but also because "overtime", obviously). Similarly a timer-controlled valve. And the overtime claims would easily have paid for fixing the aircon, or a replacement. As it was a government site it should come as no surprise that the situation was still unchanged five years on.

Neutral wire upstream of your house or a couple of houses goes fzzzzrk, and the neutral voltage downstream of that break is now at the mercy of the load between each of the phases and neutral.

Which is rarely sufficiently balanced that neutral is still more or less neutral.

Re: Live Printer

I've told this before, but anyway, back several decades ago, an uncle and his family were moving house, and my dad, his brother and I were helping getting some preparations done before the actual move. One of mine was mounting a couple of lights.

In one of the bedrooms I happened to brush the back of a hand against the wall, and felt an ominous 50Hz buzz. Not very strong, but definitely present. Checking this out some more I found that you could get a voltage probe screwdriver to light up if you also touched the bare metal valve body on one of the radiators, and the indication was strongest along a line straight up from a particular wall socket. Showing this to my uncle he declared it Not Good, and suggested I take a look at whatever was hiding under the plaster.

This turned out to be the standard (for the time the house was built) metal tubing for the wiring to the socket. It had been hammered nearly flat, with dents and jagged-edged rips, by the workmen who had redone the plaster in that room. Unfortunately it had not caused a hard short, but only sufficient leakage to get to feel it the way I did while the plaster was still slightly damp.

Re: Live Printer

Having seen some shocking (pun intended) wiring recently on supposedly good quality products

Couple of months ago I bought a rackmount powerbar; nothing special, just 10 or so C14 sockets. As it came with a standard Schuko plug and I needed to plug it in to a PDU also sporting C14 sockets I got out the security bits set and opened it up to perform an input cable transplant.

The powerbar innards were by and large just as I expected, the row of sockets spot-welded to three bus bars, and the input cable crimped on to those. However, there was also a yellow/green striped wire coming from an eyelet screwed to the metal case and crimped to one of the outer bus bars, i.e. not the ground one.

I have a grave suspicion the UPS would not have liked that.
