Prices Already Spiking at Trump’s Mysterious Gas Stations That Promised Cheap Fuel
Liberty-loving patriots who got themselves amped up about president Trump’s new gas stations are in for a rude surprise.
When the White House announced the “Freedom Fuel” network last week, it bragged that the price at the pump would be just $3.47 per gallon — in honor, of course, of “our 47th president.”
But using data on the gas price tracking platform GasBuddy, The Hill found that the locations had prices that were at least $3.57 per gallon, with multiple videos on social media reflecting the same.
Unless Trump is planning to be president again four decades from now, we’d say this attempt to glorify himself has missed the mark.
Though some Freedom Fuel prices are lower than the national average — which is hovering around $3.80, according to the AAA — they’re still fluctuating as much as what you’d see at a typical gas station. One location in New Jersey climbed past the national average to $3.89 on Wednesday, before falling again to $3.57. Some had prices as high as $4.49.
A White House representative acknowledged that Freedom Fuel wasn’t immune to the routine fluctuations of a volatile market, not to mention local pricing.
“The prices at the gas stations will fluctuate — possibly coming down even further — depending on the market and the location,” the representative told CBS News.
Experts have needled the stunt, convinced that it won’t work out in the long-term.
“Stations selling at this price, it’s not sustainable,” GasBuddy’s head of petroleum analysis Patrick De Haan told the Philadelphia Inquirer last week, noting rising crude oil prices after Trump rekindled aggressions with Iran. “Generally, when losses happen, somebody’s got to pay for it.”
How Freedom Fuel is subsidizing the cost of its cheap gas is unclear. What company is running the locations is equally opaque. Some customers said that the Freedom Fuel stations were simply existing gas stations that were rebranded.
If nothing else, it speaks to the chintziness of Trump’s self-aggrandizing projects during his second term in office. In his first year, he heavily promoted a meme coin owned by his family, the value of which immediately plummeted. He also tried to hype the launch his own “Trump Mobile” network by teasing a new purportedly made-in-the-US smartphone, which turned out to be a repackaged Chinese device.

- Gen. Chance Saltzman used his final public address as chief of the U.S. Space Force to tell allied commanders in London that a war in orbit would sweep in every nation’s satellites, because orbital mechanics does not respect the line between combatant and bystander
Gen. Chance Saltzman used his final public address as chief of the U.S. Space Force to tell allied commanders in London that a war in orbit would sweep in every nation’s satellites, because orbital mechanics does not respect the line between combatant and bystander
A war fought in orbit will not stay between the two countries that start it. That was the blunt message Gen. Chance Saltzman carried into his final public address as Chief of Space Operations, delivered to an international audience of military leaders at the Global Air & Space Chiefs’ Conference in London. Orbital conflict, the outgoing Space Force chief argued, is no longer hypothetical, and deterrence flows from combat-credible forces rather than declarations.
The speech capped a military career spanning more than three decades and a tenure leading a service that barely existed when he took command.
The core warning
Saltzman’s central claim was geographic as much as strategic. Satellites do not respect borders. A war fought in orbit — even one initiated between two adversaries — sweeps in every nation with assets overhead.
He told the London audience that orbital mechanics will place every nation’s space capabilities in a space war zone whether those nations want to be there or not. Because the consequences will be shared, he argued, responsibility for a safe, secure, and stable space domain should be shared as well.
The message was aimed squarely at allied air and space chiefs. Saltzman framed space as a team sport — not by preference, but by physics.
Deterrence as capability, not signaling
Saltzman has spent his tenure pushing back against a version of deterrence built primarily on statements, red lines, and calculations about adversary intent. His alternative strategy asks the service to avoid operational surprise, deny adversaries the benefit of striking first, and develop counterspace capabilities that do not generate long-lived orbital debris.
The logic is that visible, credible force does the deterrent work on its own.
Saltzman argued that combat-credible capabilities should create a deterrent effect, and that if they don’t, the force will be prepared to respond to aggression.
That framing matters because it shifts the burden of prediction. Rather than trying to game out what Beijing or Moscow might do, the Space Force builds forces designed to defeat what those adversaries have already fielded — jammers, dazzlers, co-orbital interceptors, and cyber tools capable of disabling satellites.
Those warnings are grounded in a specific assessment: China and Russia are developing systems capable of jamming, disabling, or destroying satellites. That has pushed the Space Force’s focus toward what is known as space control — the ability to defend friendly assets and, if necessary, disrupt adversary space operations.
The terrestrial precedent is already visible. Widespread GPS jamming across the Middle East during recent conflicts has disrupted commercial aviation, shipping, and civilian navigation across a wide region. Space-based services are already contested infrastructure. The question is whether the platforms themselves become targets.
Saltzman’s answer is that if adversaries believe an attack on U.S. satellites can be answered — and answered without turning low Earth orbit into a debris field — the attack becomes less likely.
A service transformed in four years
![]()
When Saltzman took command, the Space Force was less than three years old. It had a thin institutional identity and no coherent long-term force design.
By the time of his farewell, the service had grown and gained visibility through its role supporting recent operations.
Under Saltzman, the Space Force introduced the Objective Force — a 15-year force-design effort meant to define the spacecraft, personnel, infrastructure, and partnerships the service will need through 2040. It also began implementing a new personnel model that blends full- and part-time service, moving away from the traditional active-reserve split. In April, nearly 250 Air Force reservists were selected to transfer into part-time Guardian roles, a step toward a single, unified component.
The budget shadow
Saltzman’s farewell came as House lawmakers signaled they would approve only a fraction of the funds the Trump administration had requested for major space programs through budget reconciliation.
The White House had requested substantial funding through the normal defense budget plus additional funding through reconciliation — a partisan-controlled maneuver rarely used for defense spending until recently. The reconciliation package was meant to fund programs including space capabilities and missile defense efforts. House leaders indicated they would back a significantly smaller reconciliation bill.
Saltzman declined to say publicly whether that shortfall would harm the service. He said he stood behind the request and called it a dramatic increase in resourcing for capabilities he considers vital. The rest, he acknowledged, is a negotiation between the executive and the legislature.
Alliances and the political weather
The London speech came after recent tensions between the United States and European allies. Saltzman’s message pushed the other direction.
He emphasized that nations are stronger as a team than individually, pointing to decades of evidence supporting that conclusion.
He also offered a rare piece of advice to uniformed leaders operating in politically turbulent times, describing military institutions in democracies as providing stability — the weight that slows movement but keeps the vessel stable in a storm.
The framing is worth pausing on. Space is one of the few remaining domains where allied cooperation is not just useful but structurally required. Satellites cross national airspace hundreds of times a day. Space situational awareness depends on ground stations scattered across friendly territory. Debris from a single kinetic anti-satellite test can threaten spacecraft belonging to dozens of nations. The physics forces the politics.
What Saltzman leaves behind
Lt. Gen. Douglas Schiess is expected to become the third Chief of Space Operations if confirmed by the Senate. He inherits a service with a clearer doctrine than the one Saltzman received, but also with sharper political headwinds, a contested budget, and adversaries whose counterspace programs have matured considerably in recent years.
One line from Saltzman’s farewell hints at how he thinks about the job he’s handing off: not all challenges must be solved, and some should simply be managed.
Acquisition speed, interoperability across allied systems, information sharing between classified and unclassified networks — these are persistent conditions of running a modern military service, not problems with endpoints. Treating them as solvable invites frustration. Treating them as manageable invites patience.
That’s a quieter argument than the headline warning about war in orbit, but it may be the more consequential one for the institution Saltzman built. The Space Force he leaves is younger than most of its guardians’ careers. It will spend the next decade discovering which of its problems are the kind that get fixed and which are the kind that get lived with.
For readers thinking about how space reshapes institutional identity and civilian imagination, our earlier piece on Artemis 2, Apollo 8, and overview thinking traces a parallel question from the exploration side of the ledger.

Europa, il DMA obbliga Google ad aprire Android e i dati di Search ai rivali dell'AI
Google dovrà consentire a OpenAI e agli altri concorrenti nel settore dell’intelligenza artificiale di accedere ad alcune funzioni di Android e a una parte dei dati utilizzati per migliorare il motore di ricerca. La Commissione europea ha definito nel dettaglio gli obblighi previsti dal Digital Markets Act, dopo una procedura avviata sei mesi fa. Bruxelles vuole ridurre il vantaggio di cui Google dispone sia nella ricerca online sia nei servizi AI, favorendo la crescita di alternative a Search e Gemini e ampliando le possibilità di scelta per gli utenti europei.
PIÙ ACCESSO AD ANDROID
Google dovrà aprire agli assistenti AI concorrenti undici funzioni di Android. Questo permetterà ai servizi rivali di interagire più direttamente con lo smartphone e di svolgere operazioni che oggi sono più facilmente accessibili a Gemini. Un assistente diverso da quello di Google potrà essere richiamato con un comando vocale, in maniera simile a “Hey Google”, e utilizzare alcune funzioni del telefono per cercare informazioni su luoghi, avviare attività o prenotare un taxi.
Le novità dovrebbero arrivare da luglio del 2027 con la prossima versione di Android. Google potrà comunque controllare che i servizi interessati rispettino i requisiti previsti per la sicurezza informatica e la protezione dei dati prima di concedere l’accesso. La Commissione ritiene che le garanzie introdotte siano sufficienti a proteggere utenti e dispositivi. Le undici funzioni non saranno quindi aperte indistintamente a tutte le aziende, ma solo a quelle che supereranno le verifiche richieste.
DATI RICERCA ANCHE A OPENAI E ALTRI CONCORRENTI
Dal prossimo gennaio, Google dovrà rendere disponibile anche una parte dei dati utilizzati per migliorare i propri servizi di ricerca. Potranno accedervi OpenAI e gli altri servizi AI che integrano funzioni di ricerca sul web. Le informazioni dovranno essere anonimizzate e serviranno ai concorrenti per migliorare la qualità dei risultati. Per la Commissione, l’accesso a questi dati può ridurre almeno in parte la distanza da Google, che può contare sulle informazioni raccolte in anni di utilizzo del proprio motore di ricerca.
Google potrà esaminare le richieste e bloccare l’accesso qualora rilevi rischi per la cybersicurezza o la protezione dei dati. Bruxelles ha previsto anche una formula per stabilire il prezzo che le aziende interessate dovranno pagare.
“Grazie a queste misure speriamo di vedere emergere alternative a Google Search e ai servizi AI di Google, come Gemini, e che gli utenti nell’Unione europea possano beneficiare di una scelta più ampia”, ha dichiarato Henna Virkkunen, vicepresidente esecutiva della Commissione europea con delega alla sovranità tecnologica.

L'ultimo aggiornamento di Windows risolve il bug dei file con nomi errati nel Cestino
Microsoft mette fine ad un piccolo problema di Windows che ha causato qualche grattacapo agli utenti, e che nello specifico riguardava il Cestino ed i file in esso contenuti.
Provando ad eliminare definitivamente un file, la finestra di conferma su Windows non mostrava il nome reale dell'elemento selezionato. Al suo posto compariva una sigla poco comprensibile composta da lettere e numeri, qualcosa che ricordava un codice interno del sistema piuttosto che il documento scelto dall'utente.
Il file però risultava identificato correttamente in tutte le altre schermate di Windows. Aprendo il Cestino, il nome era quello giusto. Anche nel caso di un ripristino non c'erano anomalie. L'errore compariva soltanto in quel passaggio preciso, subito prima della cancellazione. I dubbi e le segnalazioni, ovviamente, non hanno tardato a palesarsi.

Ninja’s microwave air fryer could be the fix for soggy reheated pizza
Ninja has added everything from ice cream makers to double-decker toaster ovens to its extensive lineup of counter-clogging appliances, but it's only now introducing its first microwave. What makes the new Ninja Crispi Microwave stand out among its many competitors is that it doubles as an air fryer. After heating your food using microwaves, you have the option to switch over to using superheated air so the results are crispy instead of soggy, while also potentially replacing two kitchen appliances with just one multitasker. It's available starting today through SharkNinja's online store for $449.
It comes with a bunch of standard microwave …

TSMC investe altri 100 miliardi di dollari nelle fonderie statunitensi
TSMC ha annunciato nelle scorse ore di aver stanziato altri 100 miliardi per ampliare la sua capacità produttiva di chip negli Stati Uniti; secondo l'amministratore delegato C.C. Wei, il denaro verrà probabilmente usato per ampliare il complesso dell'Arizona, passando dalle 8 fabbriche attualmente pianificate o già in cantiere a 12. Al momento non ci sono tempistiche precise ma è chiaro che si tratta di un progetto nel medio / lungo termine; la fonderia ha confermato che i dettagli più precisi saranno decisi anche in base alle condizioni del mercato e delle esigenze dei suoi principali clienti.
È una delle operazioni più grandi e importanti di sempre per l’intero settore dei semiconduttori, e ovviamente posiziona molto bene gli Stati Uniti in quello che oggi è considerato uno dei mercati più importanti in assoluto a livello globale. Nel complesso, l’impegno finanziario del colosso taiwanese negli USA sale quindi a 265 miliardi di dollari. La corsa globale all’intelligenza artificiale è stata citata come una delle ragioni del nuovo investimento, che peraltro arriva in un momento particolarmente positivo per TSMC: nel solo Q2 2026 ha registrato un utile netto di ben 22 miliardi di dollari, il 77% in più rispetto allo stesso periodo dell’anno precedente, soprattutto grazie alla fortissima domanda di GPU, i chip fondamentali per addestrare i modelli AI.
Possiamo dire che ormai da qualche anno TSMC non ha rivali dal punto di vista di raffinatezza, efficienza e sofisticazione dei nodi produttivi; in poche parole è il punto di riferimento per tutti i grandi protagonisti del settore. Questa posizione di leadership assoluta l'ha resa inevitabilmente molto forte in borsa, tanto da aver recentemente superato la soglia dei 2.000 miliardi di dollari di capitalizzazione.
