Check this out. Look at the intersection of the major trafficking routes in Thailand. The nexus is Chiang Rai - location of the cave system.

Let me ask you a question. Do you think Elon Musk's sub would have worked?

I hadn't paid close attention to this story, but watched some news videos yesterday.

The cave diver experts on site rejected this idea and got the kids out using their experience and expertise. The rescue was already underway by the time Musk showed up.

Musk had a team of SpaceX engineers working feverishly over the weekend to construct the device. Thai officials began the rescue operation before Musk's team had completed his work. But Musk decided to complete the device anyway and personally flew to Thailand to deliver it to the rescue site.

According to The Guardian, when Musk arrived with his device, Thai officials made it clear that it wasn't needed. "Although his technology is good and sophisticated, it’s not practical for this mission," said Narongsak Osatanakorn, the head of the joint command center coordinating the rescue effort. At that point, Thai officials had already finished rescuing at least eight of the 12 boys and were already planning the third and final rescue mission.

Musk has been apparently pissed off since this comment was made on July 10th. So when Vern Unsworth made his comment 3 days later, this had been going on for a bit.

And it wasn't a sub was it? It was just a long narrow tube that would be pulled by the divers.

Here's a comment from Ars Technica

I am a certified cave diver (both NACD and NSSCDS) and when I was living in a part of the country where a lot of cave diving takes place I was on a recovery team (fortunately I was never involved in any actual recoveries). I would be very leery about trying to use that thing in a cave with restrictions (that's the technical term for "pinch points" ). I certainly wouldn't be on the cave side of it (as opposed to the entrance side - when I was acting as a guide I wouldn't even be on the non-entrence side of fat divers if the system had restrictions). It also looks like it would be very easy for the divers to get seriously injured trying to maneuver it. Especially if, as the media has reported, there are currents in the water - and in low-to-no visibility conditions as has also been reported. It would also be exhausting and dramatically increase the divers' breathing gas use. Without knowing more about the actual circumstances in a given rescue, I can see almost no advantages in trying to use that in a real cave over what the divers are doing now. Both are very, very dangerous but the tube adds the possibility of trapping or injuring divers as well as the rescued person (and everyone else further in the cave).

I don't know from this story but I wonder if any actual cave divers were involved in the development of this thing or if this is another example of the modern tech world not knowing what it doesn't know. Cave diving is not like open water diving and this is a circumstance where the "move fast and break things" approach is one I wouldn't want anything to do with. The people to listen to in this circumstance are not people in the tech community but the actual divers in the water there. There is a reason that so much specialty cave diving equipment is made in north-central Florida and not silicon valley.

I don't question the designers' motives, just how workable a solution this in this case.

The criticism of the tube was that since it was 5 feet long and rigid, it couldn't maneuver around bends. Another interesting comment from Ars Technica. This seems practical, if it was watertight.

Another company designed what was effectively a body bag with an air supply. That would be much simpler to manoeuvre than this rigid cylinder. And simpler to move when empty as it could be folded.

It appears that the Tesla effort made have been always thought of as a backup plan.
