I'm not an expert in this, so consider this just wild speculation- but I wonder how much of a market there is really is for SSTs? The advent of cheap and high-quality videoconferencing software and the ubiquity of fast internet seems to me like it would cover most of the "I need to go do business across the ocean, quickly" use case that dominated the clientele for Concorde.

Bring back ocean liners. Why speed across the globe on a plane only to sit in quarantine for a fortnight at your destination?

From the accounts I've seen, flying in the concorde was loud as poo poo and kind of sucked. Also, good luck ever flying a supersonic plane over a populated area. "We've made it over a state no one gives a poo poo about, time to break everyone's windows."

How about Rigid Airships again? All the selfie opportunity of a plane with all the slow pace of a ship. Admittedly, I'm not sure how well they'd do in high-wind conditions.

Yeah my dad flew on it once and said it was basically just another plane trip that wasn't as long as normal. Plane travel loving sucks. Like, it's the most human thing possible to take soaring across the edge of space and getting from one side of a continent to the other in a few hours and make it an almost completely miserable experience.

Lighter‐than‐air craft are in the unenviable position of being too slow to outrun weather and too fragile to ride it out. Weather forecasts have greatly improved since their heyday, but not enough to entirely eliminate the risk.

What we need is for states to stand up to the Republican hate-boner against Amtrak and build up high-speed rail infrastructure. Every interstate freeway should have a high-speed rail line parallel to it that is only used for commuter traffic and not at the mercy of freight. They've been trying to kill Amtrak for years, generally even more than they've been trying to kill the USPS. My dream is for high-speed rail with car carriers so you could drive on in Eugene and drive off in Portland or Seattle, things like that.

Also with all these self-driving talks, I always thought they will have self flying and landing planes completely without pilots in most commercial flights before we get self driving cars. Because airports are a much more controlled environment with all the guidance system and flight variable being controlled, yet due to liability and a bunch of technical issues or possibly unforeseen issues, we still dont have it. I mean they can still tout things such as "avoiding pilot error" and "save on piloting cost" while having a much easier time to design for a supposedly very limited usage case for self flying and landing.

When you think about it, “lighter‐than‐air” is a misnomer. Every vehicle yet built weights far less than eleven quintillion pounds. Airships are really equally‐dense‐as‐air‐at‐their‐operating‐altitude craft.

I was under the impression that autopilot landings are already extremely common. But nobody wants to make a big deal about it. Unpopular opinion time: We will have self-driving car ability when we invent AGI, if we ever do. And then it'll be useless.

Beef posted:OSHA: the game just entered Early Access I bought it on impulse based on some random bits of media yesterday that informed me of it. It's definitely OSHA as gently caress. It's literally a zero-G shipbreaking simulator, exactly as it says on the tin. The missions involve you trying to bust up spaceships for scrap in a semi-organized yard. If you're not careful you will absolutely get bashed by something you tried to pull off too hard with your grappling tool, or if you aren't careful about where you're cutting on a ship, you could hit a fuel line and cause a massive explosion. It's early access, obviously, and feels like it in some ways, the content is pretty barebones right now, but it's fun as gently caress to just bounce around in outer space and cut up old spaceships.

If we ever did start building such things, I would be completely on board with extra mandatory training / some sort of license endorsement with blocked entrances to ensure only those how did the training can enter those expressways. I know implementing it would be a nightmare and someone people will find a way around it but just as a thought experiment.

Someone posted the smarter every day video where Destin gets to go to a nuclear submarine. When it is surfaced, it is exposed to cold air and can get below freezing. I think he experienced -30 when he was in Alaska, so it's not out of the realm of possibility that part of the sub could get near that -100 at some point.

The important material science in this situation is you don't measure at -100 to know the performance at -100. You do it to put the material on a curve to know it doesn't have any cold specific defects that could impact expected performance at -20. Do you need to go down to -100? Maybe not but that's something you get the quality leader, contract lawyers, and professional engineer together to find out if your alternative is ok.

Keep in mind that nuclear subs were originally designed back when there was Arctic sea ice, and so they were expected to be able to penetrate the ice sheet during surfacing. So part of the hull may be flash-cooled to -100 F at a time when it needs to be very strong. I mean the tester is probably right that they should phase out that requirement since the sea ice will be gone within our lifetime but still there's a whole process for that that she should have followed.

I think he experienced -30 when he was in Alaska, so it's not out of the realm of possibility that part of the sub could get near that -100 at some point. Given that the coldest temperatures ever reported on earth were lower than -100 I'd say it's pretty reasonable to expect it to happen at least once in the lifetime of the combined submarine fleet.

Being exposed to and cooling down to are two very different concepts. Suffice to say the testing would probably be more complicated if -100 self temp was actually in the operating envelope for the parts. Because of the concept of tolerance. You don't just test at operating conditions, you test beyond them. Why are people even bending over backwards to try to imagine some scenario where the USNavy is literally in Uranus.
