The cybertruck is the only car he engineered.
He is the richest guy on earth. He could do anything. Fly his personal airship over the alps. Go scuba-diving at the best spots. Invite the smartest or funniest people on earth for a personal chat. Or he could fund artists. Go jet-skiing in the maledives. Do really cool things. But all he does is spitting insults on Twitter. Which is pathetic
well put. he could use his fortunes and companies to move the US away from petroleum, instead builds luxury products. he could use his fortunes and companies to end world hunger and aid the least able to stop displacement from climate change… instead builds AI data centers belching out effluence and swastitrucks and turns twitter into a cess pool while jumping in to CUT aid to entire continents.
he’s the worst of us. at every turn, instead of doing the human thing, he chooses selfish garbage.
anyway thanks for coming to my ted talk, nationalize spaceX!
So, you know how a good thermos keeps its contents hot or cold, depending on what you put in it?
You know the trick they use to do that? They use a vacuum.
Heat can be passively transferred using convection, conduction and radiation. Convection requires the movement of fluid, there’s no fluid in a vacuum so that can’t happen. Conduction requires that one vibrating molecule causes another adjacent molecule to vibrate. Again, not possible in a vacuum because there are no molecules to transfer that vibration. That leaves radiation.
(In a thermos it’s not quite that simple. A thermos isn’t floating in space, the outside needs to connect to the inside somehow, so even though there’s a big vacuum bottle, the heat gets transferred through the parts that aren’t in a vacuum.)
Radiation is possible in a vacuum, it’s just really inefficient. People used to see radiation transfer in a vacuum all the time: incandescent light bulbs. They’re much more rare these days. But, in that case a filament was heated up so much that it glowed white hot. To reduce the heat transfer, that white hot filament was put in a vacuum – the bulb of the light bulb. If you ever touched one, you know they got hot. But, the filament was 2500 celsius, and the bulb itself was maybe slightly over 100C. That shows how inefficient radiation is. Even with something that’s thousands of degrees, it only heated the glass of the bulb from say 20C to 120C.
So, it’s hard to dump heat in space. The only thing that works is radiation, and radiation is much less effective when things are not glowing white hot. In addition, anything in space is getting heated up by the sun. So, not only do you need to dump any heat the device produces itself, it also needs to dump any heat it’s receiving from the sun.
What are two of the main things that datacenters need? Power and cooling. The need for power is famous because it’s driving up electricity costs. The need for cooling is well known because of all the water being used.
To meet the power needs, a datacenter would need massive solar panels to collect as much sunlight as possible. The solar panels on the ISS provide about 30kW of power. A small datacenter (and I mean small), uses 1 MW. So, for one small DC you’d need 30x the number of solar panels as on the ISS. If you’re talking a conventional pre-AI datacenter, it’s more like 100MW, so you’d need 3000x the number of solar panels as on the ISS.
Solar panels create electricity from sunlight, but by design they have to be facing the sun, which means they get heated up too. So, before you even turn on a computer in the DC, you have to find a way to dump all that heat that the solar panels are creating. Then, let’s say you want to actually turn on the computers in the DC. On earth can be cooled by dumping water on something hot and letting water evaporate. That’s really easy to do, and really cheap. You just move the heat from the computers into the water and it goes into the sky. But, in space, there’s no sky to evaporate into, and no source of water. So, you need radiative cooling. Now, just imagine how much radiative cooling you’d need to match the performance of a simple “dump water on it” cooling system.
tl;dr: The idea of datacenters in space is ludicrous. Even someone as stupid as Musk knows that. But, investors are dumber than Musk – or at least investors think that there are other investors that dumb, so they won’t get stuck with the shares if they need to sell them. Musk needs the belief that datacenters in space to be possible or his shares all crash in value.
You know he only has a bachelors degree… supposedly two from the same year. And both are suspicious. From University of Pennsylvania. Same university that trump has his from.
Bachelors in economics. And physics.
And he claimed he graduated in year. 1995. But no degree could be shown for like 10 years. And then when one finally surfaced in 2009, which magically was needed for a legal litigation , it had a different year on it. 1997.
The people he was in that legal battle with said he dropped out of college in 1995. Never finished his economics degree. Never studied physics.
It also wasn’t a graduate level degree like he claimed.
It’s highly suspicious because now he suddenly has two degrees for the same year. One in economics. And one in physics. 1997. When he was working on PayPal or something else. But had time to finish two degrees!?
The degree copies were made public 2009.after he made a very generous endowment.
Also the supposed bachelors of physics is an arts degree. Which is pretty unusual for a science based degree.

Guy is a fraud. Bought two fake degrees.
Wasn’t dean of university of Pen in the Epstein files?

Anywho
He’s not even an engineer. He actually didn’t know about vacuum cooling.
Just like I didn’t. Cause I’m also not educated in physics or engineering.
Lots of math degrees are BAs and double degree path is a thing, but yeah a lot of details don’t add up.
anything in space is getting heated up by the sun
Just keep it on the dark side of the moon, duh.
How does earth cool? Through radiation. If the data centers stay on earth, earth will heat up. At some point there will be so many data centers that earth cannot take more heat.
I mean, yes, but that amount of heat is fairly negligible, especially relative to global warming from fossil fuel emissions.
There is no limit and with robots there can be exponential growth in construction velocity. Almost all available energy, including space solar farms and both nuclear energies, could be used for AI. If the data centers are on earth that will heat earth faster than radiation can cool it.
There are few things funnier than someone being wrong at the top of their voice.
Especially when it’s the world’s richest narcissistic psychopath being wrong at elementary school level. This is not forbidden knowledge - a majority of the people on the planet probably know how a thermos flask works.
Elon Musk is the personification of a moron’s hallucination of a genius.
ketamine/cocaine/expensive wine and pedophelia personified.
Fun fact: Musk isn’t an engineer at all.
Engineering qualifications are pretty specific, and usually the term shouldn’t be used loosely if those qualifications aren’t there. Musk’s education ended at the Baccalaureate level, but crucially in Physics and Economics. He pushes himself as some kind of engineering mastermind, but it’s hard to pin down why.
Contrary to popular belief, he also is not a founder of Tesla.
he is a engineer of ketamine usage,
Technically he is founder of Tesla though. He just didn’t found it.
For some reason, in the US you can buy the title of “founder of X”. He just bought if from the actual founders.
I mean, he found out that there was a company called Tesla and then became CEO…
Yeah. The Wiki offers the more sane answer.
To be fair, Engineer isn’t a protected title in the U.S.
A Professional Engineer is, but I don’t think I’ve ever seen anyone claim Musk is a P.E.
Titles ending on engineer is so bloated, basically anything within IT is an engineer. A support level 1 engineer. A software engineer. A Quality Assurance engineer. And the list goes on, historical reason being corporate pay bands being based on titles, hence engineers were offered better pay
Fair
All that money, power and fame… and he types slurs at people who criticize him online. There are many facets of pathetic to this.
Elon Musk isn’t an engineer. He’s a capitalist. (Plays with money)
Tesla is a good car? 🤔🧐🤨😐
I mean yeah… They are ugly as shit, have stupid fucking interiors and some serious QA issues, but to this day Tesla makes one of the most solid EV drivetrains on the market. The Model Y was the global top-selling car for a reason.
The reason is the hype, though. Consumers are not rational, and the Chinese EVs were blocked out, too.
I mean, no, not really. They were fine 20 years ago when for a brief time they were better and cheaper (due to being heavily subsidized) than pretty much anything else on the market, and the free supercharger network was pretty much the only way to charge on the go. They’ve since been vastly surpassed, and have only decreased in quality as you admit. They’re definitely not great cars anymore.
188k likes? I don’t Twitter. Is the echo chamber really that bad or does he just have it set to automatically give him like 150k likes on every post through the backend?
Sadly I think there really are 188,000 dickheads on Twitter.
As well as his fellow Nazis, Musk is also wildly popular within a certain subset of the business community in Asian and African countries who are more culturally insulated from his political unpleasantness, but all think that if they can become his friend by liking and commenting on all his posts then he’ll invest in their shitty startups.
most likely bots, I doubt elon has a lot of real followers.
There are a lot of edgy techboys who still thinks he is great, mostly because they hope to leech off of his billions in some unexplained way.
Wtf Teslas are good cars? Debatable. But how does that make Elon a good engineer? He is the hype man and has absolutely nothing to do with the engineering of the cars.
They are right about the whole datacenters in space thing tho. Getting power and losing heat is very hard in space. And we’re not even talking about the effects of radiation on the hardware, the depreciation making ROI impossible and the added costs of getting it up there. Literally the exact same hardware but on the ground instead of space would make more money. Not to mention the latency and unable to repair or upgrade anything. Anyone who’s ever been to a datacenter knows those things have people coming and going all the time, they require maintenance. And calling it a datacenter is beyond ridiculous, even if they launch the biggest sat ever made, it wouldn’t even have a fraction of what a small modern data center can provide. Just going bigger isn’t a simple thing at all, transporting heat and power around is hard. And materials have limits, a solar panel can only be so large before natural oscillations shake the thing apart.
The only thing datacenters in space do is keep SpaceX in business, which is something Elon wants, so for him they are great. For the rest of the world, not so much. There is zero reason for any compute to be in orbit.
And Musk could have easily scored big points if he invested heavily into solar panels combined with the battery tech they already have. If those datacenters would provide energy instead of taking it away, that’s at least one concern less. And even if the whole AI thing collapsed and the datacenters became useless, they would still make good solar farms and energy storage. If they would help stabilize the grid with their batteries, getting a connection to the grid wouldn’t be as big of an issue. But instead they chose the worst fucking option, gas powered turbines for local energy production. Bad for the environment, making lots of noise and local pollution plus driving up the cost of fuel. At least they aren’t building coal plants, but it’s close.
And the only solar Musk ever promoted was a total scam, nothing of what he told investors about those solar roofs was true. And not of it ever worked, the whole thing was non-functional. How Musk isn’t in jail for that or one of the many other times he lied to investors is a mystery to me. Oh no it’s not, he has money and laws don’t apply to rich people, my bad.
There is zero reason for any compute to be in orbit.
The one reason I can think of is to lower Starlink latency by around 1-2ms to whatever services they’re providing if you’re connecting directly to the satellite that does the compute, but I’d struggle to come up with many actual use cases for that there where the juice is worth the squeeze.
I can see why he’d want it since there’d be a lot of cross-sell opportunities there, i.e. use Starlink if you want lower latency to our hosted servers, and use our hosted servers if you want Starlink subscribers to have lower latency to your service. Maybe the point isn’t to put a giant warehouse of supercomputers there, it’s just to get enough to run a bunch of Counter-Strike 2 and TURN servers. But that’s speculation on my part, I’ve no idea what the dozy bellend is actually thinking.
Solar is already being installed anywhere they can. Getting a connection to the grid isn’t that easy, and often requires paying for the transmission and distribution upgrades needed - which also get implemented on a timescale to suit the grid operator, ie in no rush, whenever they’re good and ready.
Battery storage wouldn’t last long enough and would require a much larger footprint than turbine generators. However the turbines are more expensive to run than importing from the grid - they’re for security of supply, not for constant operation (although I’m sure they’d happily run them if no grid connection was available).
Point being I don’t think there is a practical option where data centres could export to the grid - they already install solar on the roof, and it isn’t that big of an area (big solar farms take up a ton of space). With wind turbines you have to worry about ice throw, so they can’t be too close. Whatever option it’s basically a separate installation with its own land acquirement and planning permission needs.
Hot damn
Imagine having more money than your extended family could ever spend, the ear of the President, unelected power over governmental institutions, zero accountability, your entire family line can do anything and everything they could ever want… and still choosing to spend your limited time on this planet arguing with internet trolls, hoarding money, and throwing slurs at the science people who made your company and obscene wealth possible. That’s why billionaires are pathetic…
I could spend it.
On what?
High-level plans on my desk by Tuesday
Can’t even pay off the debt of the US, plenty of ways to spend it
My favorite part of is that the reason there is so little convective heat transfer is space is the same reason the temperature is so low.
I get this isn’t super common knowledge but yikes lol
What if you’d run metal pipes or radiators outside, with (hot) water running through them? Would that also not cool the water down?
But in movies the astronauts get cold when there is low power and freeze when the suit is punctured. Arnold removed his helmet on Pluto and froze. This is proof it’s cold. /s
I know everyone’s got a different set of filters but how does it take one until the cool things in space post to find out, if they’re curious enough to know of space radiators already?

no matter how many times i re-read this I’m lost as to what you’re asking.
but, in space, without a medium for convection (like air rising and taking energy with it), you have simple radiation - any time a surface is above absolute zero, it’s probably radiating something in the ‘thermal’ end of the spectrum.
I mean that if someone is intelligent/educated/curious/enough of a mere science enjoyer if not well educated themselves,
to for instance, know that you need radiators to dump heat in space,how has that person not already noticed Elon Musk showing his ass?
he certainly is ignorant as hell. and to reply with a slur, well… he’s a fascist piece of trash, so I guess we shouldn’t expect him to understand basic thermodynamic principles - add it to the list of things he apparently doesn’t understand. it’s long.
ketamine is one hell of a drug
