We all make mistakes. I once forgot to include gravity in a pressure drop calculation for a 100 ft vertical pipe as part of a steam drum system. I had to send an awkward email revising the design pressure I previously communicated out.
But hey, if we were perfect, we wouldn’t need peer review.
I have a little bit of experience with limit switches, but that’s really interesting. It certainly seems like an unusual system. I’m a lot more familiar with safety relays.
It really says something when even oil companies will design for these considerations but Tesla won’t.
I’ve unfortunately been working on process control strategies for almost a year now on new and novel applications for my company, so I’ve been intimately familiar with this. If it isn’t obvious, this isn’t my favorite professional area of interest hahaha.
Designating fail open and fail closed valves is so intrinsic to what I’ve been doing that I can’t imagine someone designing a car control system and not thinking about that at all.
It’s basic safety for industrial plants to designate powered equipment as “fail open” or “fail closed” or on/off. It’s shocking that this wasn’t applied to Tesla cars.
We really need an industry that performs industrial grade HAZOPs on consumer products and publishes a report for everyone to see.
Might be the doors are fail shut if anything happens… But that seems like the worst design ever.
Come to think of it, it’s basic design to designate features as fail closed/fail open on loss of power in an emergency, and you go with what’s inherently safe. It appears Tesla did not consider basic safety design. To no one’s surprise.
Poor reading comprehension. Typical lib.
Once more, overcompensating way too hard and needlessly throwing around terms to try and make yourself look like an actual leftist. You know what the clearest sign of this is, liberal? Other than you basically going “no u”?
I never said a thing about the USSR lacking compassion to animals. Nor did I ever mention NASA nor make a judgment on which group was morally superior. That all came from you, because you felt the need to bolster your leftist “credentials”. But I see through it.
It’s not terribly surprising that both NASA and the USSR space program did awful things to animals. They were racing each other, moving quickly and breaking things. It would be too risky to test humans in incredibly novel technology like that, but they wanted data and results. So they tortured poor animals instead of taking the time to go more slowly and do safer tests. And let me be explicitly clear, both space programs are guilty of this and damnable for it.
What’s your next reply going to be, I wonder? Ignoring basically everything I said, and talking about more of NASA’s fuck ups, like “well we don’t know it doesn’t work” with Challenger? Sprinkling in some leftist terms to convince yourself you aren’t a liberal? Or will you totally pivot to something else and call me Clyde again?
Please, mix it up a bit this time. The formula is getting rather dull. There’s better ways to try and convince us you aren’t a liberal.
I think there’s something to be said for medium sized companies. I work for one that’s trying to grow and become much larger, but it’s decidedly not big. Our execs though actually seem like pretty cool people, and the CEO seems to be a legitimately good person. He’s generally been open and honest, and he’s told stories that make me think he does actually value employees as people.
He was talking about gay rights and the value of diversity during our weekly company forum the other day, and I asked him about our company’s support for DEI given the political pressure from conservatives to abandon it. He said he didn’t give a damn about them, and doing the right thing was more important. I don’t agree with everything he’s done – we’ve had layoffs, and morale isn’t great, and we’re totally broke – but I respect that he actually seems to mean what he says. And even when we had layoffs, executives and management weren’t safe either.
I think a lot of what it comes down to is the genuineness of leadership and how closely tied they are to rank and file employees. That’s easier at small and medium companies. Large companies also tend to attract greedy robber barons.
That’s fair. The way I look at it is that executives curb what the employees actually believe and want to work on. I saw this at a petrochemical company that was part of a big oil company. Everyone was excited about sustainability projects and cutting emissions and renewable technology. The execs just didn’t give a shit and continued to push for oil and drilling. If workplaces were democracies, we’d see so much more wonderful things.
It’s well known that horrible things happened to animals during the Russian space program.
You sound like a liberal trying way too hard to pretend they aren’t one by coming up with absolutely shit takes which are demonstrably incorrect. I’m actually surprised I didn’t realize this until now. You’re so over the top that overcompensation is the most charitable explanation.
In an ideal world, yes. But most people aren’t willing to lose their jobs and healthcare, potentially putting their family’s financial situation in dire straits, over protesting this.
Don’t blame the workers. Blame the executives.
The old saying goes that Russian history can be summarized as “And then it got worse.” The Russians are victims of their own history, and they are the first group that Putin terrorized (quite literally with the known false flag operation).
They have such a rich culture and truly bright minds. There could be wonderful scientific collaboration and cultural exchange. I’d love to see a technological rivalry reminiscent of the cold war (without all the proxy fights and nuclear threats and animosity).
I hope that it’ll be in my lifetime where we’re able to sit down and drink beer and vodka together and be on friendly terms as countries.
That’s not disappearing. That’s blatant killing.
Disappearing is sudden government abduction with no paper trail. You criticize the government and then all a sudden, your colleagues and friends don’t know what happened to you and can’t contact you.
It’s an important difference. Disappearing is more ominous and has a greater chilling effect. The government isn’t putting you in a comfortable hotel, and they aren’t killing you silently. They’re torturing you for punishment and for information, and threatening your family. It’s far more sinister.
We’ll need it anyway to produce existing chemical materials sustainably. It may not be the best energy carrier nor most efficient, but it shines in specific applications. Vehicles are a promising example.
There’s companies working on it! We’re just broke
And yes, this is definitely the dirty kind. It may still be an improvement on using natural gas directly, but there would need to be a fairly comprehensive analysis to tell for sure. One possible advantage though is we could start building up a hydrogen infrastructure that we can then feed green hydrogen into and completely replace the dirty hydrogen.
Anyway though, you’re right to be skeptical. It’s important though to look into the details to determine if it’s legitimately green energy or if it’s just oil companies greenwashing. We need to shun the latter while we promote the former.
(There is a grey area, and it’s the same as electric cars – if we’re using electricity from the grid to power cars, and electrolyzers which make hydrogen, is it truly green? I would say this is acceptable for the same reason EVs are acceptable. It’ll become completely emission free once the grid is run on renewables.)
It depends a lot on where the hydrogen is sourced from. Hydrogen that is generated from electrolyzers using renewable power is completely green (and funny enough, called Green Hydrogen), and is a good way to store excess energy from solar and wind.
Oil companies however want to market hydrogen from drilling and refining, which is dirty as hell.
It’s an important differentiation to make though. Hydrogen is not inherently bad and will have plenty of green applications. We just have to make sure it’s coming from the right places.
Please tell me you meant racist and not raciest
This can be intuitively understood if you’ve gone through difficult college classes. There’s two ways to prepare for exams. You either try to understand the material, or you try to memorize it.
The latter isn’t good for actually applying the information in the future, and it’s most akin to what an LLM does. It regurgitates, but it doesn’t learn. You show it a bunch of difficult engineering problems, and it won’t be able to solve different ones that use the same principle.
Not of children. You have to get written permission from their parents – or you used to, at least.
It happens! The important part is review and learning from the mistakes.
