Starlink
Starlink
It’s like giving billionaires access to do reckless shit that can literally impact humanity’s future may be problematic.
Wow
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.
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
They'll probably build a solar farm.
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 energy or 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.
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.
Additionally, existing users are mostly in urban centers with very efficient infrastructure, starlink gives high bandwidth internet everywhere.
I’d like to see the CO2e cost of giving a user in the middle of Idaho or Montana a 100Mbps connection.
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.
I hate Elon maybe even more than the next guy, but there are some major exaggerations here:
Starlink makes tons of maneuvers to avoid collisions: https://www.space.com/starlink-satellite-conjunction-increase-threatens-space-sustainability
Starlink is at an orbit that they are quickly returning to Earth and burning up on re-entry: https://cybernews.com/news/starlink-lost-200-satellites/
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 use them all or 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.
So I don’t really like the idea of defending anything related to Musk, but it’s kind of poor form to compare emissions between Starlink and land-based internet imo. Although they are the same product, they are targeted at completely different users, from what I understand.
Starlink should always be a more expensive and slower technology just because of communication distance, so it shouldnt really be able to compete with land-based solutions (except where telecom is reeeeeally fucking people on price). Starlink is really meant more for edge-cases where telecorps refuse to build infrastructure.
Starlink isn’t meant for the edge cases, the edge cases can not make it profitable. The edge cases are edge cases.
Also blotting out the sky with wasteful satalites isn’t a good solution to “the free market wont build infrastructure because its broken.” Its just another aspect of it being broken and the entire planet has to suffer from it.
That is not a viable market. It’s far too small for the cost.
And they can’t compete. It’s all backed by investor money. It’s the same disruption business that big tech has been doing for decades. Enter market, subsidize costs with investor money, become incumbent as everyone thinks it’s such a good deal. Raise prices when there’s no other option.
Uber, netflix, Spotify, same plan again. Never better, never competitive, just disruptive.
ah yes, the “you used flowery language to make a point and thus I’ll decide that everything you said is wrong!” technique

unfortunately Scientists have no power, so they are basically begging these companies to work with them to find solutions and the companies just aren’t doing that. The best they can do is twice the maximum brightness scientists have called for, www.nature.com/articles/s41550-020-01238-3 estimates there could be 100,000 of these objects in the sky in the 2030s, 30x the amount we have currently.
astronomy is massively impacted by all of this, just because America refuses to build infrastructure like everyone else does, thanks America. Thanks Musk.
Starlink should always be a more expensive and slower technology just because of communication distance
That is not correct. The target of Starlink is satellite-to-satellite data routing in as close to a straight line as possible between point A and point B. Even adding the 500Km up and 500Km down, starting at several 1000Kms that’s less distance than going through the network of ground fiber cables.
You would think a progressive community would look at ALL the factors of such an endeavor and analyze them in a real world setting taking into account all the various variables.
Instead of focusing on ONE positive and acting as if all the negatives are automatically outweighed by that one positive.

Como adjudicatario del Programa UNICO Demanda Rural del Ministerio de Asuntos Económicos y Transformación Digital, Hispasat pone a disposición de los operadores minoristas una plataforma de recursos de red para la prestación de un servicio de calidad disponible en el 100% del territorio español. Se trata de una solución mayorista en la que se emplean satélites geoestacionarios en banda Ka de última generación.
Spain isn’t the market for Starlink.
Try something a little more rural.
for example in spain: conectate35.es where they have internet for 35 euros a month, in any part of the territory with 100mbps download speed
map of spain, there are plenty of rural areas that are loosing population and leaving old towns completely deserted because they lack internet connection
Pick one or the other, you’re literally arguing both sides of the fence here.

It looks like the study they linked only addresses the CO2 produced by the satellites, and not the land based providers.
From the study: Another interesting thing is that OneWeb and Kuiper (competing satellite internet services) are estimated to have significantly more per-user emissions than Starlink (40-200% more emissions!) (keep in mind that Starlink is predicted to have the most users) while also being estimated to provide a worse service and be more expensive per user. (all taken from the charts on page 6)
They also mention that Starship will likely lower carbon emissions of later Starlink launches significantly.
I’m not quite sure how the much larger Starlink V2 design factors in to all of this, or if they even took it into account.
So you don’t know either?
How do the other satellite competitors even matter here?
I’m actually surprised internet takes 3% the amount of energy it takes to get to space just to run some internet wires. I’d have thought it would be much much lower than that.
But also, starlink completes with geostationary satellite and home cellular connection more than internet over wires. Or even people who didn’t have an option before.
Did your intuition consider the energy required to dig a trench to bury the cale in? Or putting up posts to lift the cable off the ground? I didn’t consider it at first, but neither is done with climate neutral machinery.
The operational requirements are probably pretty similar, the satellites are obviously exclusively solar powered, so no contribution there.
