You can make a brick fly if you strap enough thrust ($$$$) to it. That doesn't mean a human without suicidal thoughts would ever want to be strapped to the same brick.
This is hot wheels. It's pretty clear Musk finally had enough of the culture wars at X and decided to go interfere with Tesla some more. Instead of producing a car people might actually want, he made them do this. This is the worst waste of a company you're likely to see in your life.
TSLA is probably not a good stock to be holding right now.
Not at a PE of ~336 in a world where BYD will eventually arrive in the US.
But TBF if they offered the SpaceX thrusters as an option, the SF effective altruists would slurp them right up to be their daily drivers even if they have to be strapped in next to a tank of toxic boom boom to use them. And Sam Altman would cry into his protein-supplemented energy drink because his Koenigsegg doesn't have them and I'd happily hand over 50 Quatloos to watch that.
1. The kind of person who buys a sports-car often doesn't want the "base version". They want luxury. They want status. They don't want to face the choice of being upsold to an impractical deathtrap or driving around in the "base version" like someone who could barely just afford it.
2. This demo does absolutely nothing to demonstrate the abilities of the base version. I reiterate, a brick could have been made to fly in this way. The base version will no doubt have good paper stats because Musk understands that numbers must be big, but that doesn't mean the base model will be pleasant to drive.
3. The styling of this car is "wankpanzer with a few extra polygons". Given how well the wankpanzer sold, demand for this thing, even if the base model is a competent auto, will be limp.
4. Musk is currently trying to buy another election. With Musk visibly taking an interest in Tesla again, that's likely to backfire on Tesla. They need to cut ties with Musk, not keep doing the sort of puerile things he's known and frequently lambasted for.
5. When does this silly thing even release? They say 2028, but do we believe them? How long has it been since the last model released? We're talking half a decade between models. What the heck are they doing at Tesla? Making bricks fly apparently.
> You can think of the COPV like the fuel tank in a compressed natural gas (CNG)- or liquid propane gas (LPG)-powered vehicle, except the nitrogen mixture in the COPV is stored at a much higher pressure, up to 10,000 psi, similar to the pressures in modern hydrogen fuel-cell vehicles.
LPG explosions are real combustion due to tank rupture (often due to installation damage or rust). A nitrogen COPV can not rupture (that's why the CO in COPV is there) but it can leak. And that COPV, when it leaks, will be a rocket. But not an explosion.
10,000 PSI? That is beyond absurd. I can not imagine what alloy and how wrapped that pressure vessel is... Or what type of crazy pump is recharging it!
"'Initial analysis indicates the potential failure of a pressurized tank known as a COPV, or composite overwrapped pressure vessel, containing gaseous nitrogen in Starship's nosecone area, but the full data review is ongoing,' the company wrote in an update on Thursday (June 19)."
> LPG explosions are real combustion due to tank rupture…
That first video is terrific - but it demonstrates bringing the pressure vessel far beyond design limitations. Would you like to see what a tank of gasoline does when taken far outside design limitations?
The other two videos are triggered by the copv failing, but the explosion is due to the methane and lox.
My point still stands. The composite overwrap either survives a collision (crash tests will determine this) or doesn't (the vehicle will not be legal for sale in the US and Europe). The crash conditions are inside the design limitations, just like the batteries are and just like a standard fuel tank is.
I'm not able to find solid numbers on that, but given the shared heritage (I presume those gas thrusters come straight from SpaceX) and premium in a space vehicle for payload space, and the fact that SpaceX lost four vehicles to the things, I suspect similarly quite high.
My assumption was that pressures would be lower to help with the longevity of the air chamber, versus a more “disposable” nature of rocket equipment. I am assuming they are replaced between launches.
I hate to be the one to tell you, but you probably pass at least one very explosive tank of something very volatile each and every day on your commute.
This thing is literally a fucking bomb if it fails, through accident or degradation.
The down-force negative pressure aspect they gleaned from McMurtry though? Really cool. Genuinely useful. I just hope they don't claim it as their own invention.
That sounds extremely explosive and not something any random person should be irresponsibly driving around.
