Head to Print Head: CNC vs FDM


It’s a question new makers often ask: “Should I start with a CNC machine or a 3D Printer?”– or, once you have both, every project gets the question “Should I use my CNC or 3D printer?” — and the answer is to both is, of course, “it depends”. In the video embedded below by [NeedItMakeIt] you can see a head-to-head comparison for one specific product he makes, CRATER, a magnetic, click-together stacking tray for tabletop gaming. (He says tabletop gaming, but we think these would be very handy in the shop, too.)

[NeedItMakeIt] takes us through the process for both FDM 3D Printing in PLA, and CNC Machining the same part in walnut. Which part is nicer is absolutely a matter of taste; we can’t imagine many wouldn’t chose the wood, but de gustibus non disputandum est–there is no accounting for taste. What there is accounting for is the materials and energy costs, which are both surprising– that walnut is cheaper than PLA for this part is actually shocking, but the amount of power needed for dust collection is something that caught us off guard, too.

Of course the process is the real key, and given that most of the video follows [NeedItMakeIt] crafting the CNC’d version of his invention, the video gives a good rundown to any newbie just how much more work is involved in getting a machined part ready for sale compared to “take it off the printer and glue in the magnets.” (It’s about 40 extra minutes, if you want to skip to the answer.) As you might expect, labour is by far the greatest cost in producing these items if you value your time, which [NeedItMakeIt] does in the spreadsheet he presents at the end.

What he does not do is provide an answer, because in the case of this part, neither CNC or 3D Printing is “better”. It’s a matter of taste– which is the great thing about DIY. We can decide for ourselves which process and which end product we prefer. “There is no accounting for taste”, de gustibus non disputandum est, is true enough that it’s been repeated since Latin was a thing. Which would you rather, in this case? CNC or 3D print? Perhaps you would rather 3D Print a CNC? Or have one machine to do it all? Let us know in the comments for that sweet, sweet engagement.

While you’re engaging, maybe drop us a tip, while we offer our thanks to [Al] for this one.

Kill Switch! L’arma digitale di Donald Trump che minaccia l’Europa


Il ritorno di Donald Trump alla Casa Bianca è diventato un doloroso promemoria per l’Europa della sua principale vulnerabilità digitale: il “kill switch” di fatto controllato dagli Stati Uniti. Rischi politici che solo pochi anni fa sembravano una fantasia sono ora percepiti come una minaccia molto reale , in grado di paralizzare l’economia e le comunicazioni europee.

Nel corso degli anni di integrazione economica e globalizzazione tecnologica, i paesi europei sono diventati estremamente dipendenti dai servizi cloud americani. La sicurezza di e-mail, streaming video, elaborazione industriale e persino comunicazioni governative è direttamente collegata all’infrastruttura controllata dalle tre maggiori aziende americane: Amazon, Microsoft e Google. Queste aziende attualmente servono oltre due terzi del mercato cloud europeo.

Da tempo si esprimono preoccupazioni circa un’influenza indebita degli Stati Uniti sui dati europei. Le leggi americane consentono alle autorità statunitensi di accedere alle informazioni archiviate sui server di queste aziende in tutto il mondo. Ma da quando Trump è tornato al potere, tali scenari sono diventati molto più vicini alla realtà.

La situazione si è aggravata dopo che la Corte penale internazionale ha emesso mandati di arresto per importanti politici israeliani e al procuratore capo della Corte, Karim Khan, è stato impedito l’accesso ai suoi account di posta elettronica ospitati sui server Microsoft. Sebbene l’azienda stessa si sia rifiutata di divulgare i dettagli della chiusura, l’incidente ha suscitato grande scalpore. Aura Sallah, ex importante lobbista di Meta a Bruxelles e ora membro del Parlamento europeo, ha sottolineato che una situazione del genere dimostra chiaramente che l’affidabilità e la sicurezza delle piattaforme digitali americane per l’Europa sono seriamente in discussione.

Come ha osservato Zach Myers, direttore del think tank CERRE, l’Europa è un concorrente e un avversario per Trump, non un alleato. Pertanto, l’idea che le autorità americane possano deliberatamente disattivare i servizi cloud per aumentare la pressione politica non sembra più fantascienza.

In risposta al peggioramento della situazione, politici e aziende europee stanno intensificando gli sforzi per ridurre la dipendenza tecnologica dagli Stati Uniti. Il capo dell’azienda francese OVHcloud, Benjamin Revkolewski, ha paragonato i servizi cloud a un sistema di approvvigionamento idrico: familiare e impercettibile finché qualcuno non chiude la valvola. E se la possibilità di un simile blocco era precedentemente discussa in teoria, oggi è percepita come un rischio reale.

Per ridurre almeno in parte il grado di dipendenza, le più grandi aziende americane si sono affrettate a dimostrare la loro disponibilità al dialogo. Microsoft ha incluso garanzie legali nei contratti con le agenzie governative europee per mantenere l’accesso ai servizi, anche in caso di decisioni politiche da parte di Washington. Amazon ha annunciato un nuovo meccanismo per la gestione dei servizi europei, promettendo di garantirne il “funzionamento indipendente e continuo”, anche qualora gli Stati Uniti introducessero nuove restrizioni.

Eppure molti dubitano che tali promesse resisteranno alle pressioni della Casa Bianca. Come sottolinea l’economista Cristina Caffarra dell’University College di Londra, anche con le migliori intenzioni, le aziende non saranno in grado di tenere testa al proprio governo se il confronto politico raggiungerà un nuovo livello.

In questo contesto, nell’UE si stanno diffondendo richieste di creare infrastrutture digitali proprie e indipendenti. Una di queste iniziative è il progetto EuroStack, con un investimento previsto di 300 miliardi di euro. Il suo obiettivo è garantire la piena indipendenza dell’Europa nel campo delle tecnologie e del software cloud. Il piano prevede commesse governative prioritarie per le aziende IT locali, sussidi e un fondo di sostegno.

Ma l’ambizioso progetto sarà estremamente difficile da attuare. Come ammettono anche i suoi sostenitori, l’entità dell’investimento è paragonabile ai budget delle più grandi riforme infrastrutturali degli ultimi decenni. Gli scettici, compresi i rappresentanti delle lobby americane, sostengono che i costi reali potrebbero superare i 5 trilioni di euro.

I responsabili politici dell’UE si trovano a dover bilanciare il desiderio di sovranità tecnologica con il timore di essere accusati di protezionismo, che potrebbe innescare una dura risposta da parte degli Stati Uniti. Gli Stati membri sono divisi: la Francia è irremovibile sulla necessità di proteggere i dati dall’influenza americana, mentre i Paesi Bassi, tradizionalmente fedeli agli Stati Uniti, hanno in passato adottato una posizione più cauta. Tuttavia, le turbolenze politiche degli ultimi mesi hanno costretto anche loro a riconsiderare il loro approccio.

Il problema è aggravato dal fatto che le iniziative legislative volte a rafforzare la sovranità digitale sono bloccate. Uno dei progetti chiave, che prevede la certificazione obbligatoria delle soluzioni “cloud” per le agenzie governative, è bloccato in fase di approvazione. Secondo l’idea, il livello di certificazione più elevato avrebbe dovuto garantire la protezione dei dati da interferenze da parte di paesi terzi, inclusi gli Stati Uniti. Ma sotto la pressione di Washington, i negoziati si sono protratti a lungo e la Commissione europea si rifiuta di divulgare la corrispondenza con la parte americana, citando la “necessità di mantenere la fiducia”.

Nel frattempo, Bruxelles sta sempre più insistendo sulla necessità di una politica rigorosa e pragmatica. Come ammette Henna Virkkunen, responsabile del dipartimento UE per la sovranità tecnologica, l’Europa si trova per la prima volta di fronte a una situazione in cui la sua dipendenza economica e tecnologica può essere usata come arma nei conflitti internazionali.

La posta in gioco finanziaria, tecnologica e politica è altissima. L’Europa deve decidere se è disposta a pagare per l’indipendenza o se preferisce continuare a sperare che il passaggio all’estero non venga mai effettuato.

'A Black Hole of Energy Use': Meta's Massive AI Data Center Is Stressing Out a Louisiana Community


A massive data center for Meta’s AI will likely lead to rate hikes for Louisiana customers, but Meta wants to keep the details under wraps.

Holly Ridge is a rural community bisected by US Highway 80, gridded with farmland, with a big creek—it is literally named Big Creek—running through it. It is home to rice and grain mills and an elementary school and a few houses. Soon, it will also be home to Meta’s massive, 4 million square foot AI data center hosting thousands of perpetually humming servers that require billions of watts of energy to power. And that energy-guzzling infrastructure will be partially paid for by Louisiana residents.

The plan is part of what Meta CEO Mark Zuckerberg said would be “a defining year for AI.” On Threads, Zuckerberg boasted that his company was “building a 2GW+ datacenter that is so large it would cover a significant part of Manhattan,” posting a map of Manhattan along with the data center overlaid. Zuckerberg went on to say that over the coming years, AI “will drive our core products and business, unlock historic innovation, and extend American technology leadership. Let's go build! 💪”

Mark Zuckerberg (@zuck) on Threads
This will be a defining year for AI. In 2025, I expect Meta AI will be the leading assistant serving more than 1 billion people, Llama 4 will become the leading state of the art model, and we’ll build an AI engineer that will start contributing increasing amounts of code to our R&D efforts. To power this, Meta is building a 2GW+ datacenter that is so large it would cover a significant part of Manhattan.
Threads


What Zuckerberg did not mention is that "Let's go build" refers not only to the massive data center but also three new Meta-subsidized, gas power plants and a transmission line to fuel it serviced by Entergy Louisiana, the region’s energy monopoly.

Key details about Meta’s investments with the data center remain vague, and Meta’s contracts with Entergy are largely cloaked from public scrutiny. But what is known is the $10 billion data center has been positioned as an enormous economic boon for the area—one that politicians bent over backward to facilitate—and Meta said it will invest $200 million into “local roads and water infrastructure.”

A January report from NOLA.com said that the the state had rewritten zoning laws, promised to change a law so that it no longer had to put state property up for public bidding, and rewrote what was supposed to be a tax incentive for broadband internet meant to bridge the digital divide so that it was only an incentive for data centers, all with the goal of luring in Meta.

But Entergy Louisiana’s residential customers, who live in one of the poorest regions of the state, will see their utility bills increase to pay for Meta’s energy infrastructure, according to Entergy’s application. Entergy estimates that amount will be small and will only cover a transmission line, but advocates for energy affordability say the costs could balloon depending on whether Meta agrees to finish paying for its three gas plants 15 years from now. The short-term rate increases will be debated in a public hearing before state regulators that has not yet been scheduled.

The Alliance for Affordable Energy called it a “black hole of energy use,” and said “to give perspective on how much electricity the Meta project will use: Meta’s energy needs are roughly 2.3x the power needs of Orleans Parish … it’s like building the power impact of a large city overnight in the middle of nowhere.”

404 Media reached out to Entergy for comment but did not receive a response.

By 2030, Entergy’s electricity prices are projected to increase 90 percent from where they were in 2018, although the company attributes much of that to damage to infrastructure from hurricanes. The state already has a high energy cost burden in part because of a storm damage to infrastructure, and balmy heat made worse by climate change that drives air conditioner use. The state's homes largely are not energy efficient, with many porous older buildings that don’t retain heat in the winter or remain cool in the summer.

“You don't just have high utility bills, you also have high repair costs, you have high insurance premiums, and it all contributes to housing insecurity,” said Andreanecia Morris, a member of Housing Louisiana, which is opposed to Entergy’s gas plant application. She believes Meta’s data center will make it worse. And Louisiana residents have reasons to distrust Entergy when it comes to passing off costs of new infrastructure: in 2018, the company’s New Orleans subsidiary was caught paying actors to testify on behalf of a new gas plant. “The fees for the gas plant have all been borne by the people of New Orleans,” Morris said.

In its application to build new gas plants and in public testimony, Entergy says the cost of Meta’s data center to customers will be minimal and has even suggested Meta’s presence will make their bills go down. But Meta’s commitments are temporary, many of Meta’s assurances are not binding, and crucial details about its deal with Entergy are shielded from public view, a structural issue with state energy regulators across the country.

AI data centers are being approved at a breakneck pace across the country, particularly in poorer regions where they are pitched as economic development projects to boost property tax receipts, bring in jobs and where they’re offered sizable tax breaks. Data centers typically don’t hire many people, though, with most jobs in security and janitorial work, along with temporary construction work. And the costs to the utility’s other customers can remain hidden because of a lack of scrutiny and the limited power of state energy regulators. Many data centers—like the one Meta is building in Holly Ridge—are being powered by fossil fuels. This has led to respiratory illness and other health risks and emitting greenhouse gasses that fuel climate change. In Memphis, a massive data center built to launch a chatbot for Elon Musks’ AI company is powered by smog-spewing methane turbines, in a region that leads the state for asthma rates.

“In terms of how big these new loads are, it's pretty astounding and kind of a new ball game,” said Paul Arbaje, an energy analyst with the Union of Concerned Scientists, which is opposing Entergy’s proposal to build three new gas-powered plants in Louisiana to power Meta’s data center.

Entergy Louisiana submitted a request to the state’s regulatory body to approve the construction of the new gas-powered plants that would create 2.3 gigawatts of power and cost $3.2 billion in the 1440 acre Franklin Farms megasite in Holly Ridge, an unincorporated community of Richland Parish. It is the first big data center announced since Louisiana passed large tax breaks for data centers last summer.

In its application to the public utility commission for gas plants, Entergy says that Meta has a planned investment of $5 billion in the region to build the gas plants in Richland Parish, Louisiana, where it claims in its application that the data center will employ 300-500 people with an average salary of $82,000 in what it points out is “a region of the state that has long struggled with a lack of economic development and high levels of poverty.” Meta’s official projection is that it will employ more than 500 people once the data center is operational. Entergy plans for the gas plants to be online by December 2028.

In testimony, Entergy officials refused to answer specific questions about job numbers, saying that the numbers are projections based on public statements from Meta.

A spokesperson for Louisiana’s Economic Development told 404 Media in an email that Meta “is contractually obligated to employ at least 500 full-time employees in order to receive incentive benefits.”

When asked about jobs, Meta pointed to a public facing list of its data centers, many of which the company says employ more than 300 people. A spokesperson said that the projections for the Richland Parish site are based on the scale of the 4 million square foot data center. The spokesperson said the jobs will include “engineering and other technical positions to operational roles and our onsite culinary staff.”

When asked if its job commitments are binding, the spokesperson declined to answer, saying, “We worked closely with Richland Parish and Louisiana Economic Development on mutually beneficial agreements that will support long-term growth in the area.”

Others are not as convinced. “Show me a data center that has that level of employment,” says Logan Burke, executive director of the Alliance for Affordable Energy in Louisiana.

Entergy has argued the new power plants are necessary to satiate the energy need from Meta’s massive hyperscale data center, which will be Meta’s largest data center and potentially the largest data center in the United States. It amounts to a 25 percent increase in Entergy Louisiana’s current load, according to the Alliance for Affordable Energy.

Entergy requested an exemption from a state law meant to ensure that it develops energy at the lowest cost by issuing a public request for proposals, claiming in its application and testimony that this would slow them down and cause them to lose their contracts with Meta.

Meta has agreed to subsidize the first 15 years of payments for construction of the gas plants, but the plant’s construction is being financed over 30 years. At the 15 year mark, its contract with Entergy ends. At that point, Meta may decide it doesn’t need three gas plants worth of energy because computing power has become more efficient or because its AI products are not profitable enough. Louisiana residents would be stuck with the remaining bill.

“It's not that they're paying the cost, they're just paying the mortgage for the time that they're under contract,” explained Devi Glick, an electric utility analyst with Synapse Energy.

When asked about the costs for the gas plants, a Meta spokesperson said, “Meta works with our utility partners to ensure we pay for the full costs of the energy service to our data centers.” The spokesperson said that any rate increases will be reviewed by the Louisiana Public Service Commission. These applications, called rate cases, are typically submitted by energy companies based on a broad projection of new infrastructure projects and energy needs.

Meta has technically not finalized its agreement with Entergy but Glick believes the company has already invested enough in the endeavor that it is unlikely to pull out now. Other companies have been reconsidering their gamble on AI data centers: Microsoft reversed course on centers requiring a combined 2 gigawatts of energy in the U.S. and Europe. Meta swept in to take on some of the leases, according to Bloomberg.

And in the short-term, Entergy is asking residential customers to help pay for a new transmission line for the gas plants at a cost of more than $500 million, according to Entergy’s application to Louisiana’s public utility board. In its application, the energy giant said customers’ bills will only rise by $1.66 a month to offset the costs of the transmission lines. Meta, for its part, said it will pay up to $1 million a year into a fund for low-income customers. When asked about the costs of the new transmission line, a Meta spokesperson said, “Like all other new customers joining the transmission system, one of the required transmission upgrades will provide significant benefits to the broader transmission system. This transmission upgrade is further in distance from the data center, so it was not wholly assigned to Meta.”

When Entergy was questioned in public testimony on whether the new transmission line would need to be built even without Meta’s massive data center, the company declined to answer, saying the question was hypothetical.

Some details of Meta’s contract with Entergy have been made available to groups legally intervening in Entergy’s application, meaning that they can submit testimony or request data from the company. These parties include the Alliance for Affordable Energy, the Sierra Club and the Union of Concerned Scientists.

But Meta—which will become Entergy’s largest customer by far and whose presence will impact the entire energy grid—is not required to answer questions or divulge any information to the energy board or any other parties. The Alliance for Affordable Energy and Union of Concerned Scientists attempted to make Meta a party to Entergy’s application—which would have required it to share information and submit to questioning—but a judge denied that motion on April 4.

The public utility commissions that approve energy infrastructure in most states are the main democratic lever to assure that data centers don’t negatively impact consumers. But they have no oversight over the tech companies running the data centers or the private companies that build the centers, leaving residential customers, consumer advocates and environmentalists in the dark. This is because they approve the power plants that fuel the data centers but do not have jurisdiction over the data centers themselves.

“This is kind of a relic of the past where there might be some energy service agreement between some large customer and the utility company, but it wouldn't require a whole new energy facility,” Arbaje said.

A research paper by Ari Peskoe and Eliza Martin published in March looked at 50 regulatory cases involving data centers, and found that tech companies were pushing some of the costs onto utility customers through secret contracts with the utilities. The paper found that utilities were often parroting rhetoric from AI boosting politicians—including President Biden—to suggest that pushing through permitting for AI data center infrastructure is a matter of national importance.

“The implication is that there’s no time to act differently,” the authors wrote.

In written testimony sent to the public service commission, Entergy CEO Phillip May argued that the company had to bypass a legally required request for proposals and requirement to find the cheapest energy sources for the sake of winning over Meta.

“If a prospective customer is choosing between two locations, and if that customer believes that location A can more quickly bring the facility online than location B, that customer is more likely to choose to build at location A,” he wrote.

Entergy also argues that building new gas plants will in fact lower electricity bills because Meta, as the largest customer for the gas plants, will pay a disproportionate share of energy costs. Naturally, some are skeptical that Entergy would overcharge what will be by far their largest customer to subsidize their residential customers. “They haven't shown any numbers to show how that's possible,” Burke says of this claim. Meta didn’t have a response to this specific claim when asked by 404 Media.

Some details, like how much energy Meta will really need, the details of its hiring in the area and its commitment to renewables are still cloaked in mystery.

“We can't ask discovery. We can't depose. There's no way for us to understand the agreement between them without [Meta] being at the table,” Burke said.

It’s not just Entergy. Big energy companies in other states are also pushing out costly fossil fuel infrastructure to court data centers and pushing costs onto captive residents. In Kentucky, the energy company that serves the Louisville area is proposing 2 new gas plants for hypothetical data centers that have yet to be contracted by any tech company. The company, PPL Electric Utilities, is also planning to offload the cost of new energy supply onto its residential customers just to become more competitive for data centers.

“It's one thing if rates go up so that customers can get increased reliability or better service, but customers shouldn't be on the hook to pay for new power plants to power data centers,” Cara Cooper, a coordinator with Kentuckians for Energy Democracy, which has intervened on an application for new gas plants there.

These rate increases don’t take into account the downstream effects on energy; as the supply of materials and fuel are inevitably usurped by large data center load, the cost of energy goes up to compensate, with everyday customers footing the bill, according to Glick with Synapse.

Glick says Entergy’s gas plants may not even be enough to satisfy the energy needs of Meta’s massive data center. In written testimony, Glick said that Entergy will have to either contract with a third party for more energy or build even more plants down the line to fuel Meta’s massive data center.

To fill the gap, Entergy has not ruled out lengthening the life of some of its coal plants, which it had planned to close in the next few years. The company already pushed back the deactivation date of one of its coal plants from 2028 to 2030.

The increased demand for gas power for data centers has already created a widely-reported bottleneck for gas turbines, the majority of which are built by 3 companies. One of those companies, Siemens Energy, told Politico that turbines are “selling faster than they can increase manufacturing capacity,” which the company attributed to data centers.

Most of the organizations concerned about the situation in Louisiana view Meta’s massive data center as inevitable and are trying to soften its impact by getting Entergy to utilize more renewables and make more concrete economic development promises.

Andreanecia Morris, with Housing Louisiana, believes the lack of transparency from public utility commissions is a bigger problem than just Meta. “Simply making Meta go away, isn't the point,” Morris says. “The point has to be that the Public Service Commission is held accountable.”

Burke says Entergy owns less than 200 megawatts of renewable energy in Louisiana, a fraction of the fossil fuels it is proposing to fuel Meta’s center. Entergy was approved by Louisiana’s public utility commission to build out three gigawatts of solar energy last year , but has yet to build any of it.

“They're saying one thing, but they're really putting all of their energy into the other,” Burke says.

New gas plants are hugely troubling for the climate. But ironically, advocates for affordable energy are equally concerned that the plants will lie around disused - with Louisiana residents stuck with the financing for their construction and upkeep. Generative AI has yet to prove its profitability and the computing heavy strategy of American tech companies may prove unnecessary given less resource intensive alternatives coming out of China.

“There's such a real threat in such a nascent industry that what is being built is not what is going to be needed in the long run,” said Burke. “The challenge remains that residential rate payers in the long run are being asked to finance the risk, and obviously that benefits the utilities, and it really benefits some of the most wealthy companies in the world, But it sure is risky for the folks who are living right next door.”

The Alliance for Affordable Energy expects the commission to make a decision on the plants this fall.

Eulogy for the Satellite Phone


We take it for granted that we almost always have cell service, no matter where you go around town. But there are places — the desert, the forest, or the ocean — where you might not have cell service. In addition, there are certain jobs where you must be able to make a call even if the cell towers are down, for example, after a hurricane. Recently, a combination of technological advancements has made it possible for your ordinary cell phone to connect to a satellite for at least some kind of service. But before that, you needed a satellite phone.

On TV and in movies, these are simple. You pull out your cell phone that has a bulkier-than-usual antenna, and you make a call. But the real-life version is quite different. While some satellite phones were connected to something like a ship, I’m going to consider a satellite phone, for the purpose of this post, to be a handheld device that can make calls.

History


Satellites have been relaying phone calls for a very long time. Early satellites carried voice transmissions in the late 1950s. But it would be 1979 before Inmarsat would provide MARISAT for phone calls from sea. It was clear that the cost of operating a truly global satellite phone system would be too high for any single country, but it would be a boon for ships at sea.

Inmarsat, started as a UN organization to create a satellite network for naval operations. It would grow to operate 15 satellites and become a private British-based company in 1998. However, by the late 1990s, there were competing companies like Thuraya, Iridium, and GlobalStar.

An IsatPhone-Pro (CC-BY-SA-3.0 by [Klaus Därr])The first commercial satellite phone call was in 1976. The oil platform “Deep Sea Explorer” had a call with Phillips Petroleum in Oklahoma from the coast of Madagascar. Keep in mind that these early systems were not what we think of as mobile phones. They were more like portable ground stations, often with large antennas.

For example, here was part of a press release for a 1989 satellite terminal:

…small enough to fit into a standard suitcase. The TCS-9200 satellite terminal weighs 70lb and can be used to send voice, facsimile and still photographs… The TCS-9200 starts at $53,000, while Inmarsat charges are $7 to $10 per minute.


Keep in mind, too, that in addition to the briefcase, you needed an antenna. If you were lucky, your antenna folded up and, when deployed, looked a lot like an upside-down umbrella.

However, Iridium launched specifically to bring a handheld satellite phone service to the market. The first call? In late 1998, U.S. Vice President Al Gore dialed Gilbert Grosvenor, the great-grandson of Alexander Graham Bell. The phones looked like very big “brick” phones with a very large antenna that swung out.

Of course, all of this was during the Cold War, so the USSR also had its own satellite systems: Volna and Morya, in addition to military satellites.

Location, Location, Location


The earliest satellites made one orbit of the Earth each day, which means they orbit at a very specific height. Higher orbits would cause the Earth to appear to move under the satellite, while lower orbits would have the satellite racing around the Earth.

That means that, from the ground, it looks like they never move. This gives reasonable coverage as long as you can “see” the satellite in the sky. However, it means you need better transmitters, receivers, and antennas.
Iridium satellites are always on the move, but blanket the earth.
This is how Inmarsat and Thuraya worked. Unless there is some special arrangement, a geosynchronous satellite only covers about 40% of the Earth.

Getting a satellite into a high orbit is challenging, and there are only so many “slots” at the exact orbit required to be geosynchronous available. That’s why other companies like Iridium and Globalstar wanted an alternative.

That alternative is to have satellites in lower orbits. It is easier to talk to them, and you can blanket the Earth. However, for full coverage of the globe, you need at least 40 or 50 satellites.

The system is also more complex. Each satellite is only overhead for a few minutes, so you have to switch between orbiting “cell towers” all the time. If there are enough satellites, it can be an advantage because you might get blocked from one satellite by, say, a mountain, and just pick up a different one instead.

Globalstar used 48 satellites, but couldn’t cover the poles. They eventually switched to a constellation of 24 satellites. Iridium, on the other hand, operates 66 satellites and claims to cover the entire globe. The satellites can beam signals to the Earth or each other.

The Problems


There are a variety of issues with most, if not all, satellite phones. First, geosynchronous satellites won’t work if you are too far North or South since the satellite will be so low, you’ll bump into things like trees and mountains. Of course, they don’t work if you are on the wrong side of the world, either, unless there is a network of them.

Getting a signal indoors is tricky. Sometimes, it is tricky outdoors, too. And this isn’t cheap. Prices vary, but soon after the release, phones started at around $1,300, and then you paid $7 a minute to talk. The geosynchronous satellites, in particular, are subject to getting blocked momentarily by just about anything. The same can happen if you have too few satellites in the sky above you.

Modern pricing is a bit harder to figure out because of all the different plans. However, expect to pay between $50 and $150 a month, plus per-minute charges ranging from $0.25 to $1.50 per minute. In general, networks with less coverage are cheaper than those that work everywhere. Text messages are extra. So, of course, is data.

If you want to see what it really looked like to use a 1990-era Iridium phone, check out [saveitforparts] video below.

If you prefer to see an older non-phone system, check him out with an even older Inmarsat station in this video:

youtube.com/embed/mOvUxoA7Ngs?…

So it is no wonder these never caught on with the mass market. We expect that if providers can link normal cell phones to a satellite network, these older systems will fall by the wayside, at least for voice communications. Or, maybe hacker use will get cheaper. We can hope, right?

trump dice che è stato un successo "spettacolare". qualcuno si interroga sulla scelta di questa parola da parte di un capo di stato che ha lanciato un attacco militare che ha anche spezzato vite? sarà stato un successo. un successo importante. ma "spettacolare". cosa è un film? uno spettacolo? oppure sono comunque morte persone vere nell'attacco? il cinismo di questo presidente è veramente RIPUGNANTE.

"La caduta di Fordow: gli Usa abbattono il bunker simbolo del nucleare iraniano". ecco. esatto. probabilmente la parola chiave è proprio solo "simbolo". da verificare che davvero ci fosse qualcosa.
