The Tesla flying car is clearly a Spectacle for Fools, but the gas being used is basically compressed air and doesn’t contribute to our greenhouse gas problem.
There’s plenty of other aspects to this to make fun of that are factually accurate.
And you think the gas just compresses itself?
Mine does.
So, you suck? 🤔
No, you blow to compress air, you suck to decompress air.
If your gas is compressing itself, it’s creating a high-pressure environment in your, err, guts. That means it’s creating a lower-pressure area outside - i.e. you are sucking gas in to compress it.
Farting or belching - i.e. ‘gas’ in American - is rapid /decompression/, not compression.
(In practice, I think it’s rather more a case of gas is /created/ by biological means, i.e. it is not ‘compressing’ anything per se.)
It’s possible that you suck more for not being able to take a joke, though.
I’m pretty sure you blow
Sorry pet, you’re not my type.
It uses an electric compressor.
“It” does nothing of the sort.
But yes, it’s likely that an electric cryo pump would be used to fill a feed tank at the fuelling station, I wasn’t expecting it to be fuelled by unicorn farts.
Now, since apparently we have to walk this step by step for you, how do you think the electric compressor is powered? The clue is in the name “electric”, if that helps.
And for your gold star - try to work out where “electricity” comes from. In the US. You know, “clean coal” country.
Nuclear, solar, wind, hydro
Ohh, I’m sorry, I didn’t realise it wasn’t going to be sold in the US.
That is an enormous relief.
Why are you responding in such a condescending tone? Was my reply in any way as rude? Do you hold all of your internet conversations by talking down to your fellow contributors? You don’t know who we are; you don’t have any right to reply like that. Grow up. Keep your “gold stars” and “walk step by step for you’s” to yourself. If you can’t be civil to strangers, then keep your opinions to yourself.
The compressed gas that “it” uses is compressed with electricity, yes.
…and yes, I realize the gas is not compressed onboard, and that the car doesn’t accomplish this on “its” own. I’m sorry my simpler phrasing upset you so. If I say “the car uses a DC power supply,” I don’t mean to imply that the car connects “itself” to the charger either. “It” (the car) utilizes a compressed gas source, which was electrically powered.
Sure, that minuscule amount of electricity could be generated by way of fossil fuel power plants, but seeing as how this is a Tesla demo, probably a one-off (assuming Musk is lying about delivering - as he usually is), and Tesla’s “gigafactory” uses a massive solar farm in addition to the local power grid (which may include fossil fuels), it’s nearly a wash. A tiny “carbon footprint,” if any at all. Hell, manufacturing those bottle lids probably generates a larger carbon footprint.
Like [@[email protected]]\ said, there are plenty of other aspects to this to make fun of. Arguing that the compressed gas is somehow contributing to its global footprint is stupid. But then, so is arguing with strangers on the internet.
Were you homeschooled?
The energy required to flip a tonne of car is not “miniscule”, and that is the amount of energy the compressor needs to put into the gas - plus all the additional energy required because compressor and cryopump are not terribly efficient; and to cap it all, compressed gas jets are also an incredibly inefficient way to lift anything, you get roughly 25% of the compressed energy out as kinetic energy (there is a reason, after all, that SpaceX use them for attitude control, not to actually launch rockets.)
All told, hovering a 1 tonne car (which is generous, given the weight of a Tesla) with gas thrusters would require about 3 kWh of energy input per second - the fact that it gets stored as a gas instead of in a battery does not suddenly make this magic fairy dust with no environmental impact.
Back of the envelope maths and the comments from Tesla’s own engineers suggests that demo used 300kWh minimum - more if they used industrially supplied liquid nitrogen. Which is to say one numbnuts trick to impress 8 year olds used as much energy as driving a typical EV 1,500km.
If you think that is not a negative for the environment, well… Why would I expect anything else from a septic?
It’s a cool demo, but if I were holding Tesla stock I’d be kinda peeved
And you should be! Stock got a solid bump from this idiot demo and then dropped below opening price. :)
Yeah, because they’re obviously dumping a lot of engineering money into it, but it’s something that will never be practical, will probably never be legal to use on actual roads, and will never sell in any significant numbers.
Meanwhile the Chinese elites are flying around in personal drones. Actual flying vehicles.
In comparison the Tesla demo is like tying a horse to the front of a locomotive to show off the fastest horse in the world.
It’s quite sad how much him being involved in everything USA is holding us back.
Most Tesla investors are the kind to be impressed by such a stunt.
Musk made his fortune showing shiny things and making false promises to investors.
The anti-EU narratives have been pushed so widely, also by Musk himself, that even comics like the one above are spreading them uncritically. The tethered caps are not about reducing xarbon footprint but about reducing waste in our environment and high costs of cleaning effort. Yet another EU myth, especially popular among tech bros btw.
Yeah - they did a survey on european beaches and checked which plastic items they were finding. And then they tried to find a way to solve the issue by regulating the production. They did find a lot of bottle caps and plastic q-tips and then they did something against that. That is a really good way of doing things.
The attached cap is also really convenient. Never have to worry about dropping, losing, or dirtying the cap
anti-EU narratives
A bit rich from someone who loudly proclaims Russia’s invasion of Ukraine is Ukraine’s fault.
That said, anti-EU memes using the tethered caps myth are commonly found on right populist sites, so no, it is not a conspiracy.
It’s the US fault actually, they’re nothing but body bags as Soros explained
So you think the US is at fault for Russia deciding to invade Ukraine?
And you feel the EU is destroying an unspecified “us”?
Who do you blame for the US attacking Iran? What about Israel’s genocide on Palestinians?
Maybe I’m trying to make sense of the nonsensical, but I can’t say I’m following the reasoning of your worldview
anti-EU narratives
I believe this one is anti musk
Maybe so, but why is it spreading BS about the tethered caps then? The same way anti-EU memes from tech bros?
Because ignorance? I guess when I weigh these two in my head, ignorance wins but idk
I think littering and contributing more plastic waste into the environment can definitely be considered part of a person’s carbon footprint. More indirectly than burning gasoline, but it reduces recycling and requires more manufacturing and natural resources than if the plastic wasn’t wasted/littered.
In any case, it’s a pretty big stretch to label this content as “Anti-EU”, at worst they used poor word choice to make their point.
If they had said “to protect the environment” instead of “to reduce my carbon footprint” it’s the exact same comic. Tesla/capitalism is the butt of the joke here
The point is that there are tons of consumer products being made annoying so we can all feel like we’re doing our part. Meanwhile, the people generating the most pollution continue to do so.
Sure, it was compressed air. But the power required to compress the ~3 seconds of air thrusters could have driven an electric car for over a hundred miles.
That’s not flying. That’s falling in style.
Why is this car being called a Roadster? It doesn’t even appear to have a removable top. That would make it a coupé.
I am beyond sick of auto manufacturers removing the convertible option. Stop taking all the fun out of cars!
So this Tesla rocket flying car thing I’m hearing about is actually taken seriously?
Like, actual human beings with brains actually believe this shit will happen? I mean, come on now… You have a brain, evolution given, please, use it?
This is another musk thing. Elmo tells obvious lies, his groupies will repeat it as fact ad nauseum, the news sites will obviously publish said nonsense as fact because of course, and three weeks later people will have forgotten about the next bullshit lie from Elmo. Rinse and repeat, he has pulled this bullshit off dozens of times now and he keeps getting away with it. Other people would have been sued into the ground but Elmo? Nope. I guess the guy has charisma or something (the something doing all the lifting because claiming that musk has charisma is just idiotic)
Lets not forget this gem from about 5 years ago
Is he starting his own rocket league? Did one of his brood start playing it and leon thought, “I could do that!”?
To be fair, leon has the most advanced thruster/sensor tech on the planet via SpaceX. Making an empty metal box do a flip is trivial.
Is anyone else mortified by how such an obvious and blatant attention grab can so easily captivate the attention of literally every circle of the internet?
yea, they were discussing in a game im playing the other day, they actually believe it. if it wasnt an obvious distraction from MUSK TURNING OF STARSHIELD/LINK BY TELLING TRUMP TO DO IT.
They believe what? That there was a car using RCS thrusters to quasi-fly made by Tesla?
If you don’t believe that, then you’re detached from reality.
I actually didn’t see any news on this except for some coworkers asking if I saw it. First time I saw it was yesterday… on lemmy. So maybe we should do better here and not talk about it, like at all? Delete this post and move on?
Everything I’ve seen has just been about how stupid this thing is.
You should look outside of lemmy. In my circle people are genuinely impressed.
Folks on YouTube seem unimpressed as well
Not really. They made an actual flying car, and that’s just plain awesome.
We know it’s an attention grab, that’s the entire point of doing a product demonstration. You’re not special for noticing that, in fact it’s so obvious most people don’t feel the need to comment on it.
They made an actual flying car
“flying” is doing a lot of those heavy lifting, like 2000kg lifting. It’s like saying Buzz Lightyear from Toys Story can fly.
You have to be in the air longer than Kitty Hawk to call it flying. I don’t make the rules…
That space convertible shows that it was an actually car with seats and everything. All the clips I’ve seen showed a sealed cockpit and tinted windows. So it could have esially been an empty frame with is lighter to do those stunts with
Yeah, I think it was basically the RCS unit from a Space-X rocket stuffed into a car-shaped frame with some parts from an electric golf cart glued in there to move it around on the wheels.
And smaller battery pack to compensate for the pressurised tank and a compliment for Melon Husk small dick.
There have been other flying cars
“an actual flying car” “product demonstration” lmao
It’s neither a flying car nor a product that will ever be sold on the market. Crazy how gullible the average person is.
I bet you’re one of those people who insisted FSD was right around the corner 10 years ago.
This is a Flying Car. Musk has built a Fast and Furious jumping stunt car.
10 seconds of hovering ain’t exactly flying. It would have been impressive if they framed it as these are the thrusters we’ve been working on to help land on Mars, heres what we can do with them on a car.
Instead Musk just goes we can kick flip a car!!! The same presentation goes from interesting tech to eyerollingly cringe. Absolutely a cool tech but has no business being sold in a car road legal or not. It should stay a prototype tech demo.
but it made like five flips over the video! It makes for almost a minute of flying! /s-for-god’s-sake
not really, they also launched a tesla to mars awhile back
is that bottle thing a real thing? I noticed that on some of my recent water bottles and I’ve got to say, I’m absolutely livid about it.
For around a year now it’s been mandatory in the EU
It’s certainly an irritating change. If it actually makes a big a difference as the granolas say, whatever I guess. But I have doubts about it’s effectiveness. Use a nalgene or something reusable.
I was on vacation in a country without attached bottle caps. I put my cap down somewhere and spent a few minutes trying to find it. It was irritating, but I guess you get used to it.
You get used to it
There is no way its legal for cars to fly around like that. The kill enough people on the ground I dont want them trying to kickflip over traffic.
The wildest part? It’ll (probably) kick flip over and into an accident; it’s not like the speed direction is going to change with those thrusters.
You know, like games where you go left to avoid something and right into another object or pit.
Of course it’s not legal, even Tesla said so, why would this be something to question?
What’s obvious to some is a revelation to others, let them have their moment.
I pity my EMS brothers who will roll up on a car crash, that now has a massive pipe bomb to spray bits of flaming lithium in a half mile radius.
Well done Tesla. The Mother of All Car Bombs will be ready to roll off the lot next year you say?
can’t build a car that drives itself because it crashes and kills people and wants to amaze us with this dog and pony show of a car that can fly out of control and REALLY kill a lot of people. Fucking excellent job heir musk. Is this what you’ve been wasting billions of our tax dollars on? This bullshit? Hey, while we’re on the subject, did you finally stop killing monkeys and (later on) the unfortunate Mexican immigrant who came across your Texas property? That brain chip thing. You killed a LOT of critters with that one. And Mars. Fuck’s sake. Idiot talk from start to finish - and yet, MORE of our tax dollars for that dog and pony show.
and you want us to believe this tripe too?
Oh, and before you go sulk - what’s the ‘gas mileage’ like? Five minutes? Two?
OUR goddam tax dollars for THIS shit.
heir musk
You mean herr musk, heir musk is whatever little crotchspawn he picks to take over his shitheel legacy
Musk has perfected the art of bedazzling people with precision controlled compressed gaslighting.
