And what exactly do I lose? The approval of some miserable fuck who I would never want to associate with anyways? Like I give a fuck about a few downvotes from a pile of cucks
Also you telling me to move on is rich considering you’re replying to a 4 day old comment
I’m sorry you don’t understand genetics enough to know that’s not the only way you could end up with kids who don’t look like yourself. Or are totally ignorant of adoption.
They just don’t care. If they could earn a trillion knowing that the gain would destroy the planet in 10 years, they would. They’re out of control, and the states on their knees to beg their money.
Spoiler: It’s 0.1 tonnes of CO2e per subscriber per year. This is not mentioned in the article.
This includes for example the emissions generated in the course of constructing the rockets that launch the satellites. So far it’s unclear to me whether, when comparing to terrestrial telecom, they include e.g. the emissions produced when manufacturing the trucks that deploy the infrastructure.
This also means the amount of emissions per user will go down the more users they get. It’s not very fair to compare something new to something that’s been around for decades in something that is based solely on the amount of users they have. I hate starlink, but this report is trash.
Emissions are going to go down when starship is made as well.
Starship uses a methane + oxygen fuel which burns cleaner, and can be produced with just water and CO2 making it carbon neutral.
I don't think every flight will be neutral immediately, or what % will be consistently once its scaled up, but it'll be better.
But 1 carbon neutral flight sending up hundreds of satellites will bring it down quickly. They could even save the carbon neutral flights for themselves for PR purposes.
You can’t produce methane from CO2 for free. It requires extremely high pressures and then you have to add in as much as energy as you would get out of burning the methane to make methane from scratch.
SpaceX’s launch facility, where they’d likely try this stupid process, is in Texas. Texas gets most of its electricity from burning fossil fuels. So unless spaceX makes a private nuclear reactor on site to power the methane manufacturing plant, they’ll be burning fossil fuels to make electricity so they can turn C02 back into a fossil fuel. That’s not carbon neutral
But don't get me started on how there no such thing as carbon neutral because it took carbon to build the solar panels, or wind mills, and the person operating the facility had to eat vegetables which required someone to ship them, which required a EV which required power that came from solar but those solar panels which were made from panels produced via solar panels required someone else to clean them which produced co2 making their meals too!
The launch facility they have in Boca Chica is surrounded by wildlife preserves, where are they going to put a solar farm big enough for a usable methane plant?
To put it in perspective, a square meter of solar panel puts out about 200 watts.
At atmospheric pressure, a cubic meter of methane gas contains about 40 million joules of energy.
40 million/200 = 200,000 square meters of solar panels needed to produce a cubic meter of methane.
And that’s assuming the process is 100% efficient. It’s also not counting the energy needed for the pumps to pressurize plant, or the methods they would use to extract or move the carbon dioxide, or cool down the methane.
That 40million joule figure is for gaseous methane, starship needs liquid methane to run, so the methane would need to be cooled with industrial refrigeration to turn it into fuel, which adds even more energy to the equation.
For the amount of fuel Starship needs, the Sabatier process is not feasible if you’re doing it with solar panels and planning on launching more than once a year or so. Not unless they want to pave over a small city with solar panels.
Putting energy back into CO2 to get fuel is not really economically feasible. It’s a useful process for mars for example, because you can drop off the plant and have it trickle fuel into a launch vehicle while you build the base and wait for the crew to arrive.
Boca Chica isn't going to be the main launch center in the future due to things like the wildlife preserve around it. They're going to be restricted at some point. It's a R&D center.
They could also build the solar/wind elsewhere to offset anything, or maybe they could even invest in a SMR. They'll have the cash once those start coming online.
I wouldn't be surprised if they're investing money to optimize the process as well, just like we see new advances in desalination continually making it more efficient. (Edit: e.g https://iopscience.iop.org/article/10.35848/1347-4065/ace831)
Also even in Texas, it isn't going to be coal forever, more and more renewable sources are being added to the grid every year. I'm not trying to say this will be an immediate thing.
They almost certainly do not. Embodied energy is conveniently ignored 99% of the time because a) awareness of how much carbon goes into everything could result in consumers consuming less — couldn’t possibly do the almighty economy dirty like that — and b) it’s extremely difficult to calculate with any reasonable degree of accuracy.
Thank you, I was wondering how high the emissions could possibly be for Internet access from the customer’s perspective. I figured simply owning a car probably smashed even “30x as much” as other ISPs
I’d like you all to consider that places where you’d use starlink are also significantly more than 30x farther away from civilization than the average land-based internet user.
Definitely, that’s what we should do. But that will have a decent carbon footprint and more importantly our government (at least in the US) has utterly failed rural Americans (and more!) in terms of internet roll out.
That’s one of the problems with Internet access being provided by private corporations. They’re never going to service those people, because it’s not profitable to run a hundred miles of fiber for one guy in Wyoming, unless he’s crazy rich and pays for it himself. It’s the same issue the mail has, one of the many reasons the USPS is so important
Think of all the pollution that will be caused running new fiber cable to bumblefuck nowhere so 1 additional person or family can access the internet. It doesn’t make any more sense than Starlink, much less sense at that.
Fiber once it’s installed requires effectively no maintenance and it will last indefinitely until physically broken. Copper corrodes and wears out, but glass will last longer than the people who install it or the people who enjoy its use. Satellite internet from LEO requires many rocket launches per year to sustain, meanwhile fiber means rolling a truck (which is usually relatively local) anywhere a backhoe or flood or digging animal has broken it every few months or years, and these trucks are already rolling to install and maintain all of the existing services (or install new ones)
Actually it’s been working brilliantly, it’s just there’s so much of the United States to Unite with fiber that it’s taking time and continued investment. It used to be you couldn’t find fiber anywhere, now most of the farming communities I live around have at least some fiber services and it keeps growing every year. My in-laws just this month were notified they have the option to change from their 8/1mbit DSL to gigabit fiber, and they live in the boonies outside of a town of 500 nobodies ever heard of.
Seems we’re getting to where the next big hurdle is less rural fiber and more suburbs. I literally have significantly better internet options after moving to a small town of 10000 or so than my parents do in the suburbs of the capital city of the state.
Out in middle of nowhere Ohio, the only options are satellite and I’ll be damned if I’m doing to give Dish or Hughes net more money for worse speeds. Starlink is it until they actually run fiber out here.
Sadly, it seems both sides of any discussion have now mastered hyperbole, manipulating statistics, leaving out facts and stretching the truth to make their argument. You basically can’t believe anything you read any longer.
I’m in the space industry and I can tell you that anyone pretending to be an authority on orbital mechanics on the internet is full of shit. I’ve taken entire classes called “advanced orbital mechanics.” That shit is wildly hard, vaguely inaccurate, and so slow that you can only do it effectively on a computer. Even then you have to decide which variables to throw out because you if you use them all you won’t be able to calculate predictions on every satellite in time for them to be useful. Then you have to take the predictions, predict how wrong they are, and predict again based on those predictions if two satellites will run into each other.
The truth is that nobody knows if Kessler Syndrome is even real. I personally fall on the side of thinking it’s nonsense, there are too many variables that would have to go wrong all at once. It’s like being worried about winning the lottery. There have been multiple catastrophic on orbit conjunctions that have created thousands of pieces of debris. Still no Kessler Syndrome. Even in a nightmare scenario I can only see it affecting one orbital regime. The odds of Starlink effecting the orbit that GPS is in is effectively not possible. But this is not a solved field and I am not remotely an expert, I’m just tired of people who don’t know a thing about the field thinking they’re experts because they have a JWST desktop wallpaper and have 300 hours in KSP. The real experts are ancient old men and women who have been doing orbital predictions for 40 years and I’ve seen them get into yelling matches about this sort of thing.
This post got away from me but the point is this shit is so involved it effectively can’t be fact checked because you could come to whatever conclusion you want.
If there’s anything I’ve noticed using Lemmy for news (before that I didn’t really have a general news source) it’s that the headline is always wrong, and the article almost always corrects it—but all of the comments are about always just people who read the headline and act as if it’s gospel with even reading the article.
If the sites didn’t put it all beyond pay walls it might remedy that problem a little bit. Force people to jump through hoops just to read shit journalism and they will do the easier thing: debate headlines.
