Welp… seems this adage stubbornly clings to truth… kinda like that fin… holey— Our brains are all still locked to meters per second, not kilometers per hour. The mental translation takes a minute. -

Missed a golden opportunity here to call it New Evergiven, New Billy O’Tea, New Istanbul-Not-Constantinople, anything better.

I’ve found that to make it work, you have to copy the link from the little “copy link” icon, then paste it into a browser tab, then copy that link from the status bar and paste it here. You have to wait for it to pop up in the forum window before hitting “submit” too. -
Respectfully, you say this, and then anecdotes are exactly what you offered. Here’s a statistic: EV fires are ten, eighty, even a hundred times less likely to occur in the first place. Even if they are more likely to be “catastrophic” (however you’re defining that), that catastrophe is still less likely to occur. By your own statement (brine solution, etc) it’s already a solved problem, it just requires different tactics and equipment. Such is the evolution of fire response from the beginning (fighting a massive fuel spill/fire also requires special tactics and equipment).

Your information here is incredibly out of date. I can’t speak for other mfrs but a Tesla battery can take a significant amount of damage and not catch fire, as each cell is thermally isolated from the others. Here’s a Model 3 battery that went sideways into a tree, did way more damage than “landing on a sharp rock,” and didn’t catch fire. And speaking of landing on a sharp rock, you hear about the Model Y that was deliberately driven off a cliff, and not only did it not catch fire despite all the sharp rocks, everyone walked away? Also, the battery of any Tesla made today should last the life of the vehicle, and then some. An “old” pack just isn’t going to see that kind of degradation, any more than a gas engine (which also loses efficiency with age). I can post the graph if you want, I bought my first Model X used with 36k miles, sold it 40k miles later. Over that time my degradation was completely flat, I lost no meaningful amount of range. It used to be that EVs would see a sharp drop of around 10% in the first year, leading to this myth, but degradation then tapers off to little to nothing. Even that no longer seems to be the case with newer vehicles with better battery management.

Good article with some equally interesting discussion down in the comments. TL:DR due to potential delays with Starship, Orion’s heat shield, et al, NASA may be considering an Apollo-9-esq mission of putting Orion into LEO to dock with a stripped-down Starship for habitability and other tests. Or, if you believe the conspiracies, a “camel’s nose under the tent” to obviate SLS entirely… derp… here’s the article… https://arstechnica.com/space/2024/04/nasa-may-alter-artemis-iii-to-have-starship-and-orion-dock-in-low-earth-orbit/?comments=1&comments-page=1 -

For anyone else who’s brain absolutely will NOT let them rest until this useless knowledge is known… that wood be a pallet approximately 135x82x11ft and weighing 18,750 tons, and is either half the annual production of pennies or all the pennies in circulation as of 2012 depending on which nonsense interwebz source you trust. so yeah, splash. BIG splash. -

Sadly, nothing related to Tesla is ever unpoliticized for free from bias, either way. Such articles are nearly always missing important context, like the fact that most of the people caught in that mess hadn't bothered to precondition their cars prior to going to charge, which makes a huge difference. Or mention all the people who can't start their gas cars due to... dead batteries. Note you don't hear about issues like this in places like, say, Norway, or even Minnesota, where such subzero (F) weather is fairly normal and people know how to handle it. There's more than that, of course, so if you really want to discuss it I'd suggest taking it over to the relevant Tesla thread. Now that you've ranted, how about listening? It's hit over 100 a few times here, but I've never had to get into a burning hot car, because it's always cooled down remotely by the time I get in there. Also, nudge nudge... Er... socioeconomic factors and, shall we say, heavy use of alternative pharmaceuticals...

How many spherical cows can fit in a 13m ShawtyStarShip? Also keep in mind, they are still planning for ≈18m SS/SH in the long future… I see it like this: the first Starships to Mars (or a proper lunar colony) will be one-way, with wide, one-use LSS-style legs under heat shields (Martian EDL less demanding?). They’ll carry robots that will build level, solid, Mars-crete landing pads for the next, reusable Starships with stumpy-legs, which will bring the crews to finish assembling the mini-Mars-Mechazillas (MMMs) catch towers, 3D-printed in situ, to start using “standard” Starships. -

They should follow precedent and send a Cybertruck to Jupiter. -
