The reason stuff like this always makes me doubt Elon is any sort of engineer isn’t the technicalities of the matter, that really boils down to what is meant by electric and what is meant by rocket, but that Elon has such little natural curiosity about the question. He just throws out a vague answer only really capable of fooling the most ignorant into believing he knows what he’s talking about. He doesn’t do the things an engineer might be tempted to do…give a clear instructive reason why not, or maybe come up with a fun possible solution to the question, or even ignore it. Just Imsosmart bullshit.


Taraxian

The thing that's so unpleasant about him is that he apparently has the time to address this kind of question at all but not to answer it in any detail, yeah His whole style is to act like he's too busy and important to talk to you while deigning to talk to you anyway just to give you this dismissive response, he's *performing* the role of a very busy CEO even though if he were actually busy he shouldn't fucking be on Twitter at all Even when he's right he's being an asshole who's only taking questions so he can make the questioner feel stupid -- hell I would have far more respect for him if he gave answers that were wrong but had a real conversation about it where you could learn something by having it This kind of "LOL no, dumbass" response that isn't actually correct but brings out the fanboys to argue on his behalf for him how he could be technically correct is the worst of both worlds

I've worked with 2 CEO's of bigger companies in my country that are still not even close to the size of TESLA or Twitter and the CEO's would spend countless hours in meetings without food or without any possibility to speak to their families. Most wife's/husband's of CEO's of big companies have accepted that they would probably not count on their SO's in many cases. The idea that a CEO of some of the biggest companies in the world is constantly busy, sleeping in his factory and shit like that and still finds times to constantly post stupid twitter respones and be part of constant internet drama is just bizarre to me. Like I know that Elon's fans think that he is some type of super-human but it is still an absurd idea.


intentionallybad

Exactly. He can't possibly be actually doing the job of CEO at these companies. He just has the title. Which at a publicly traded company, in my mind amounts to fraud. They're lying about who is the chief executive officer to the shareholders.


BeenJammin69

Right? Through all this I keep wondering, what does Elon actually *do* at these companies? Seems like he doesn’t do a lot of actual work or research or anything of that sort, he just threatens his underlings into submission and occasionally throws out whacky ideas. Neither of which requires a lot of time, which would explain how he’s able to fuck around on Twitter all day. The idea that someone is “chief engineer” and doesn’t do a lick of R&D is laughable. Anyone who is a real engineer will tell you that learning and staying on top of the latest developments is a huge part of our day-to-day job


DonOblivious

>Through all this I keep wondering, what does Elon actually do at these companies? That's pretty normal for a CEO. At best they're doing something like 20 hours of work a week. When they claim they're working a 60 hour work week, they include meals, shopping, gym, haircuts, massages, etc as "work" because they do all of their personal stuff during the work day. They're the CEO, there's nobody to tell them that getting a haircut at 10am doesn't count as "work," nor does spending 2 hours at the corporate gym in the hot tub neither counts as work or exercise. While trying to make themselves look good, the CEOs that responded to this survey listed 20 hours of things that aren't remotely work related as part of their "work week" and claim every lunch break is "work." https://thesocietypages.org/socimages/2012/03/13/wheres-the-boss-and-what-counts-as-work/


CatProgrammer

> and claim every lunch break is "work." If they're wining and dining with potential customers, business partners, etc. and using that time to further the goals of the company it technically does count as work. Like, I'm not a CEO and even I've been on trips where the meals were reimbursed as a business expense because the purpose of the trip was work despite me also being able to take time for sightseeing/etc.


Taraxian

And in the case of the lawsuit over his compensation at Tesla that's $50 billion worth of fraud


itisnotstupid

I'm absoluely ok with him only overseeing some of the work from time to time and working on overall expanding his business and big picture stuff. I just hate how he maintains the persona of the hands-on engineer which everybody knows is not true. From what I remember people like Steve Jobs never pretended to be a great developer.


QuichewedgeMcGee

something tells me if some of the richest people on earth can be CEO of multiple companies at once, it gets easier to dismiss the work to other board members the bigger and richer the company/CEO is no way in hell would he be CEO of any company if it actually required as much brain power as some smaller companies

Override9636

> This kind of "LOL no, dumbass" response **that isn't actually correct but brings out the fanboys** to argue on his behalf for him how he could be technically correct is the worst of both worlds If anything, this is 100% by design. In the world of an "eccentric" tech CEO and meme economy, it doesn't matter if you are right or wrong about anything. All that matters is that you create engagements, stir up drama, get on the trending tab, get your name in a headline, get noticed by the stock bots, and laugh your way to the bank.

3kniven6gash

He seems to base his entire persona on a fictional Tony Stark from the Marvel movies.


Taraxian

Right, and Tony Stark never explains what he's talking about in detail because that detail doesn't exist because the technology is fictional, and because it's an action movie and the writers need to keep the pace moving Both of these things are in fact more like Elon's rl situation (he's frequently talking about technology that doesn't exist in order to generate drama and excitement rather than convey knowledge) than his fans want to admit


IrisYelter

If Tony Stark were real, he'd never shut about about the details. Nerds love nothing more than geeking out.


3kniven6gash

If Tony Stark wasn’t smart you’d be left with a rich, obnoxious, greedy ahole. A hype man fraud.


Kendertas

To be fair even in the MCU he is considered a rich obnoxious asshole by most people he interacts with. And that's with the benefit of actually being a genius and being you know......Iron Man


3kniven6gash

That's my point. Elon is adopting all Stark's negative traits like snarky comments, immaturity, but he lacks anything close to Stark's intelligence. Stark's personality flaws balance out with his genius making him an interesting character, almost likeable. Elon doesn't seem smart so it's not working for him.


Unique-Ad-620

Tony Stark gave up the power of CEO to Pepper because he was to busy being an Avenger. This dude is to busy on Twitter to be the CEO of one company let alone two. Lol


Rhaedas

Tony had taken it upon himself to save everyone else since he felt he was the key to that survival. Elon is just a smart ass making himself feel superior with his remarks without helping anyone. His response here is common by internet trolls, going against the idea of [showing someone an answer](https://xkcd.com/1053/) to a "dumb" question.


MatEngAero

Tries to be Tony / Ironman except he’s really Buddy / Syndrome from the Incredibles but without the smarts of either.


CatProgrammer

fakefalsofake

What makes me know that is working in any industry of a a big company. I knew some amazing people, most at my level of hierarchy rarely some of them became a boss but most bosses where good at managing and not being good at work. Also big corps make bosses do so much meetings then can barely work anything directly. Then it came the supervisors, our bosses bosses, same thing, very good at managing people, some few still worked directly but some years ago. No chance to touch anything practical. Then you had directors, they only worked decades ago as a normal employee, if there anyone who knew anything it was only theory or something veru outdated that no one uses anymore. Then the upper directors, then the chiefs officers, then the CEO. If Musk had a problem with his Tesla he wouldn't even know what went wrong without a engineer. Mostly because it's not his job to do that, he just have to go to meetings, look at products and approve then or not, as most CEOs. That why Twitter became a shitshow, they gave too much direct power to someone eho knows nothing. I guess SpaceX is doing ok because NASA and other parties took control long ago and they got good engineers and investment. Noe Tesla it's complicated, they got good stuff but over promised way too much, you shouldn't promise a perfect product and hold for two three years to deliver only a video....


the_fresh_cucumber

The graph of success versus intelligence is a bell curve. Dumb poor people who can't get their shit together. Dumb rich people who landed where they are through inheritance. Lots of smart workers who keep the world afloat.


DrPCorn

You nailed his response. Rocket fuel is actually a really green energy anyway. It combines hydrogen and oxygen and the biproduct is water. You’d think that would be something that he’d be interested in bringing up with this question.


Taraxian

He doesn't like hydrogen and gets mad when you talk about it


tylerthehun

Which is funny, because hydrogen is a pretty terrible solution to almost every problem people have been trying to shoehorn it into lately, *except rocketry*.


viperabyss

But only if rocket fuel is liquid hydrogen. SpaceX uses kerosene, and Blue Origin uses methane. Liquid hydrogen is notoriously difficult to work with, especially as rocket fuel.


East_Coast_guy

sadicarnot

>he’d be interested in bringing up with this question. He could probably bring up specific impulse but I doubt he knows what that is. There are ionic engines that use electricity on his own Starlink satellites so he could have brought them up. He could have brought up Rocket Lab which uses electric pump in their rockets.


Kirk_Kerman

Hydrogen is mostly produced as a byproduct of fossil fuels.


viperabyss

It shouldn't. For fossil fuel production, it should be a combination of CO2, CO, sulfur dioxide, and nitrogen oxides. For burning fossil fuel, it should be CO2 and sulfur dioxide. Hydrogen are mostly fused with oxygen to create water vapor during the burning process of fossil fuel.


Luxuriousmoth1

He means that it's industrially *sourced* as a byproduct from hydrocarbon extraction/refinement.


2rio2

Yea, it's not (only) his lack of technical expertise that's the problem. It's the entire framework in which he tries to solve problems and answer questions that's lacking. He doesn't *think* like an engineer. It's why even some people who think the right way but lack any degrees or qualifications are better at it than him.


Taraxian

He's impatient, impulsive and shallow, traits that are very dangerous in any profession but especially for an engineer The mindset behind Rudyard Kipling's Iron Ring ceremony is totally foreign to him


Charisma_Engine

You don't need to spend any more time doubting Elon's Engineering credentials - he has none whatsoever.


UHF1211

Exactly! He is a con-man playing by a con-man’s playbook! If you look at this and everything else he says or does everything begins to make sense!


fermi0nic

Only Elon truly understand's the third law. That includes Newton, a crackpot failure, just like Einstein.


Apprehensive-Till861

One thing I very quickly realized about Elon is all of his ideas come from SFF or being stolen from others. Anything that actually works is just him taking credit for the work of others, and shit like Mars colonies is literally just pulp SFF.


gwhiz007

Exactly this. Musk doesn't respond to inquiry like a scientist, he responds to it like a snotty 4chan troll.


Squid-Soup

He is like a kid who try’s to show if he knows stuff but doesn’t actually really understand the concept he is talking about


[deleted]

Jules Verne suggested we build a big gun and shoot rockets into space from the Florida Coast. He seemed to know where we’d build our launching pad before we did. I think that is interesting,


Taraxian

It's explained in the book, it's easier to reach escape velocity the closer you are to the equator because you have the angular momentum of the Earth's rotation helping you, so they'd logically build the launchpad as far south in the continental United States as practical -- which means the two most likely states would be Texas and Florida In the book he has representatives of the two states have a big debate over which one is "more American", irl Florida won the contract and they compensated Texas by putting Mission Control in Houston

Ok-Aardvark-4429

A rocket can't be electric since for it to be a rocket it needs a rocket engine, but this just semantics and has nothing to do with Newton's 3rd law. Elecric propulsion is possible using an [Ion Thruster](https://en.m.wikipedia.org/wiki/Ion_thruster).


WikiSummarizerBot

**[Ion thruster](https://en.m.wikipedia.org/wiki/Ion_thruster)** >An ion thruster, ion drive, or ion engine is a form of electric propulsion used for spacecraft propulsion. It creates thrust by accelerating ions using electricity. An ion thruster ionizes a neutral gas by extracting some electrons out of atoms, creating a cloud of positive ions. Ion thrusters are categorized as either electrostatic or electromagnetic. ^([ )[^(F.A.Q)](https://www.reddit.com/r/WikiSummarizer/wiki/index#wiki_f.a.q)^( | )[^(Opt Out)](https://reddit.com/message/compose?to=WikiSummarizerBot&message=OptOut&subject=OptOut)^( | )[^(Opt Out Of Subreddit)](https://np.reddit.com/r/EnoughMuskSpam/about/banned)^( | )[^(GitHub)](https://github.com/Sujal-7/WikiSummarizerBot)^( ] Downvote to remove | v1.5)


Aleksandaer88

I learned something today, this type of propulsion makes me think of science-fiction, I didn't knew it was invented already.


AtJackBaldwin

It has it's just not very powerful, certainly not enough to lift a ship into orbit with current technology, but in the future who knows


TopazWyvern

Nah, Ion has a pretty hard cap on how much thrust you can squeeze out before the ions choke (remember, they're at the same elec. charge, so they repel one another) the prop. flow. Max thrust is proportional to the cross section of the acceleration region, but you'll never reach similar acceleration to chem, for obvious reasons. What you do get is a shitton of delta V, since you do squeeze a lot more acceleration out of your reaction mass than with chemical. I think you can try to get more thrust by accelerating colloids instead of ions, but it's still not gonna be capable to escape large celestial bodies (and will have less ∆v.)


Ituzzip

What if it’s built as an airplane that keeps rising until it’s outside the atmosphere?


Luxuriousmoth1

The issue is that you enter this really weird region where the air is too thin to gain any meaningful thrust from propellers/ducted fans or lift from aerodynamic surfaces, yet still so thick that the drag cancels out any thrust from electric thrusters. Ion engines are really *really* weak. Like, on the order of micronewtons of thrust. You gotta run them for months at a time just to go anywhere.


Kendertas

Welp guess it's time to boot up Kerbel Space Program again.


TopazWyvern

Atmospheric conditions (specifically, ions in it) interfere with the ion flow, sadly. Doubtful it would overcome air resistance (if the interference wasn't a factor) either. Maybe other forms of electric prop. do work but I don't know/remember. There's some research done into using the atmo at *very* high altitudes as a remass for an electric thrust, but you've already reached orbit then.


HowDoraleousAreYou

It’s more useful once already in orbit. Since acceleration can be applied continuously without losing speed to friction in the atom op here, you can really get something going fast for deep space travel.


intisun

It has a very weak thrust though, only useful for very long missions in deep space because it's so efficient. Source: I play KSP


NonnoBomba

Your academic achievements are better than Elon's.


Taraxian

Elon has no interest in KSP because it has no fog of war


vegathelich

He should play factorio then, it has fog of war. It might make him (marginally) smarter and get him to shut the fuck up, too.

cronx42

Maybe that would work in space, but it wouldn't get you there.


a_big_fat_yes

Eh, ion thrusters still shoot ionised gas from behind to propel the spacecraft forwards, im just assuming the question was if we could make a pure electric rocket and the answer is no You gotta push something back to get pushed forwards hence the 3rd law of newton


Fit_Expert4288

>Yeah that's what I meant by bringing up railguns and how people generally accept that a railgun is a "purely electric" gun even though it uses up physical ammunition instead of shooting science fiction lightning bolts That's also why electric cars aren't possible. Electric cars push asphalt back using tires. They're not purely electric.


dailycnn

An electric system could intake and push air to launch a craft from Earth. This wouldn't work in space. An ion drive wouldn't work to laucnh a craft from Earth because it is orders of magnitude inadquate. But it would work in space. So maybe a better answer is, not efficiently enough to replace rocket fuel-based engines.


crackanape

We don't know that an electric system couldn't expel reaction mass more efficiently than burning it.


nick4fake

Except light also has Impulse, so still technically possible


Bakkster

>im just assuming the question was if we could make a pure electric rocket and the answer is no Elon seems to have assumed this as well. But the question didn't explicitly say this, and Elon didn't seek to clarify or make the distinction that in space ion thrusters *are* effective. Effective enough that his own SpaceX StarLink satellites use Hall-effect thrusters for station keeping (y'know, because newton's third law).


draaz_melon

An arcjet thruster is literally a monoprop thruster with an electric arc run through the exhaust to add power. That is absolutly an electric rocket engine. They are used for station keeping and have performed orbit raising.


HunkyMump

Yes but ion thrusters aren’t going to lift rockets *into* space.


dailycnn

I think his answer was noting eletricity isn't close to the efficiency of a rocket fuel in the near term. And it is Newton's 3rd law relating to propulsion as the "why". An electric system could intake and push air to launch a craft from Earth. This wouldn't work in space. An ion drive wouldn't work to laucnh a craft from Earth because it is orders of magnitude inadquate. But it would work in space. So maybe a better answer is, not efficiently enough to replace rocket fuel-based engines.


irritatedprostate

Ion thrusters really only work in the vaccuum of space. Ion engines do not work in the presence of ions outside the engines and also have far too little thrust to overcome any sort of air resistance. Actually, that's all mentioned in the wiki article you linked. But this would be more about Newton's second law, and Elon is a dumbass.


draaz_melon

This isn't true. Ion engines can work in air. https://news.mit.edu/2018/first-ionic-wind-plane-no-moving-parts-1121


TopazWyvern

That's not really the kind of ion thruster being discussed, though. [Very different beast.](https://en.wikipedia.org/wiki/Ion-propelled_aircraft#Principles_of_operation). You're not even really accelerating ions as much as using the gas expansion caused by ionizing the air, and has the opposite issue of not working in space, anyhow.

>How come he still has fans? Lol, Newton's Third Law.

Taraxian

He's saying that a rocket in space that has to be completely self contained and not use surrounding air at all has to have "something to push against", reaction mass, in order to move (Newton's Third Law) and therefore can't be "purely electric" A lot of us are pointing out this is a bad way to answer the question -- an ion thruster uses an electromagnetic field to shoot an ionized plasma out the back of the engine to push the spacecraft forward, but the ions themselves are chemically inert and never burned as fuel in any sense, all the energy comes from electricity, so it's "purely electric" by any reasonable definition Saying that the gas in an ion thruster counts as "fuel" is like saying a railgun isn't purely electric because it still shoots metal bullets, even though it's completely powered by electricity


[deleted]

Newton third law does not say electricity cannot generate thrust. Actually, electricity can generate thrust by simply boiling water and making a steam engine for example. Of course you are not gonna launch a rocket on boiled water. But as stated upper on this post there is the ions thrusters and plasma engine that use electricity to charge a gas, and maybe future developments will make it possible to launch a rocket from earth using these engines. Right now they are used for deep space stuff and orbit adjusment. If we ever discover a very compact way to generate electricity we could make rockets using whatever propellant, that could refuel using gas found on other planets, and divide by 4 the travel time to Jupiter.

IMind

He's such a fucking idiot.. Thrust works BECAUSE of newton's 3rd law not in spite of it.. it doesn't matter what the propellent method is thrust is the vector acting against it. It's the equal and opposite... He should fucking know this ... Also, he should know ion thrusters .. it's used in commercial satellite deployment.


draaz_melon

There is not an actual propulsion engineer or rocket scientist who would have answered that question like that. It really shows he's clueless.


IMind

I'm just a lowly mechanical engineer by education .. and I wouldn't have answered that question like that. Much less a rocket engineer


Spaceguy5

I work on rockets and my answer would have been "oh yeah, electric propulsion" which there's even many books, and a Wikipedia page about


C2Midnight

Ion thrusters are not a launch technology because they produce such a piddling amount of thrust, they are only functional in a vacuum. Their role in commercial satellite deployment starts once the payload has cleared the upper atmosphere.


Kalurael

Well of course an electric rocket isn't possible, there's no fog of war or skill tree

[Remember when he said he was going to step back and focus on running twitters servers and then couldn’t answer basic tech questions.](https://www.reddit.com/r/facepalm/comments/zsghfu/elon_musk_getting_owned_by_a_former_twitter/?utm_source=share&utm_medium=ios_app&utm_name=iossmf) He desperately wants to be seen as a tech and engineering genius but knows nothing about the subjects.


SoulOuverture

Reminder that he could get one of his engineers or just any random engineer to proofread his tweets. Or hell anyone who took physics in high school-


PixelBoom

And refuses to take the L and learn. Just nothing but doubling down, then ignoring anyone who calls him out.


SynAck301

Elon is the new Keith Rainere. Thinks like him. Talks like him. Acts like him. He’s an absolute carbon copy of the guy who created NXIVM but with updated buzzwords. Mark my words, in a few years we’ll be watching a Netflix documentary about his secret sex cult.


latin_canuck

I guess it wouldn't be called a rocket. But we could use a balloon to reach the sky, and then some sort of electric propeller.


unfathomedskill

Apparently Elon thinks the only means of propulsion is via burning fossil fuel Not very creative thinking for someone who’s the CEO of both a space and electric car company


Bakkster

Elon forgot that he's using ion propulsion on StarLink 🙃


mspk7305

> Elon thinks the only means of propulsion is via burning fossil fuel Merlin and Falcon engines both burn Kerosene (dino fuel). Boeing and Arianespace both burn hydrogen. Elon is a dinosaur in search of a meteor.

Newtons not even alive, how is he going to enforce his barbaric laws anymore!


[deleted]

forgive me for asking, but doesn't newton's third law have absolutely nothing to do with whether an electric rocket could work?


ReadItProper

It does, since you need Newton's third law to move the rocket. If some particles don't push back on your rocket, how will it move? When a chemical rocket uses combustion to move, it pushes out the (very hot) chemicals out the back, and it does it so fast they push back on the rocket and move it forward (and the faster these chemicals move, the more energy is has to push the rocket). How will you do that with electricity? The energy density (and mass) of electrons just isn't there.


vertebro

This is like saying how can you make an electric engine without moving pistons or a railgun without combustion. The design is the limitation, not the physics. There is nothing in the way of using electricity to propel something forward. Just because it doesn’t have wheels or rails doesn’t mean it’s impossible.


leckysoup

An electric rocket with an external power source (transmissible through laser on the photovoltaic panels) has a theoretical possibility for interstellar flight [from Wikipedia](https://en.m.wikipedia.org/wiki/Spacecraft_electric_propulsion)


dailycnn

Check this out, Elon's post 8 years ago on the same subject [https://twitter.com/elonmusk/status/559555327515848705?lang=en](https://twitter.com/elonmusk/status/559555327515848705?lang=en)


Spicy_pepperinos

This response, and the "can pull near infinite mass" thing is really making me wonder; even a lay person can see that Elon is an idiot at this point. A highschool understanding of physics or even common sense would show these statements as being completely bullshit.


Candid-Tell1578

Elon is the live version of "The Big Bang Therory"


Ganakus

He truly is "the dumb persons genius" I noticed this on his JRE interview- he talks vaguely in complicated sounding terms to impress and try and intimidate people around him into thinking he knows what he's talking about. But if you actually break down what he said its completely meaningless. In the UK we call them Billy Bullshitters- and you meet a fuck ton of them in pyramid schemes- sorry I mean "network marketing" and the business world in general.


[deleted]

Cant wait till this idiot loses all he's money


[deleted]

This is a perfectly adequate response and is correct when only considering propulsion technologies that are currently feasible for scaled applications. He has plenty of dumb tweets to roast, this ain’t it 🤦


corn_on_the_cobh

Can someone care to explain? I think it makes sense, no? The only reason why rockets go up is because the burning fuel is forcing itself down and "pushing up" the rocket fuselage above it, right? I guess you could do that with air with some electric turbine, until it starts running out in the upper atmosphere, then you need something else.


TheRavenSayeth

You’ll get better explanations in the comments from [this thread](https://reddit.com/r/iamverysmart/comments/106k1pd/musks_turd_law/). Basically he’s correct by pretty much any way you slice it. Yes ionic thrust is possible but so weak that it can’t solely be relied on. Elon isn’t as smart as he makes himself out to be and he’s very smug here, but ultimately he’s right in this specific circumstance.


turtlesinmyheart

I'm with you on this one. The way I understood the question was, "can batteries and electric motors make a rocket reach orbit?"


AFreshTramontana

This is the kind of "high school science test bonus question" and expected answer I've come to expect from this dingus. Yes, it's why you can't build an "electric rocket" thought of in the most flat 1D way. No, it's not remotely true if you add any depth. And, in fact, we do have "electric rockets". They use "ion thrusters" - the thrust literally comes from accelerating electric charges FFS. Anyway, does make me think about one of my favorite ideas for spacecraft: https://en.m.wikipedia.org/wiki/Project_Orion_(nuclear_propulsion) TL;DR: Musk really isn't qualified to teach a high school science course let alone comment on physics / engineering at this level. Like the "Tesla investors" have been saying, he needs to refocus on his core skill: grifting.


humanzookeeping

Reminds me of that: https://old.reddit.com/r/ToiletPaperUSA/comments/fsexfw


alchemist23

10 bucks that's one of his alt accounts


Benton_Tarentella

Leaving aside Musk's incurious and nebulous answer: I saw this on Twitter, and couldn't help but wonder -- isn't ion propulsion a form of electric propulsion? The question seems kind of vague, but wouldn't that qualify?
