Lithium mining has become a hot topic in Nevada largely because of Tesla’s interest in sourcing lithium hydroxide, one of the main ingredients needed for Gigafactory scale production of lithium-ion batteries.

Tesla announced it had signed a deal with Canadian company Bacanora and British company Rare Earth Minerals towards the end of August. Bacanora is a minerals explorer, while Rare Earth Minerals owns Sonora Lithium Project. That partnership is designed to develop a “low-cost”, “sustainable” mining project in Northern Mexico based on clay deposits found in the region.

The Sonora mine does not exist yet, but could yield between 35,000 and 50,000 tons of lithium deposits annually. The deal will be extended and scaled up contingent on the mine’s ability to meet Tesla’s forecasts and actual output from its Gigafactory. The two Sonora project partners will need to find debt or equity to finance the operation and Tesla is permitted under the deal to participate in financing activities.

The state of Nevada has agreed to give Tesla almost a half billion dollars in tax incentives in order to lure the Gigafactory to the site north of Reno, which seems little enough considering the increase in economic activity the factory will bring to the state. But now, a Nevada politician, Democrat state senator Tick Segerblom, has tweeted, “Tesla to get lithium from Mexico – where’s Trump when you need him?”

That got the Las Vegas Sun involved. They contacted Elon Musk, who tweeted back that press interest in the story was “unwarranted” as the lithium deal was “not exclusive” and had “many contingencies”. He said that Tesla would “definitely” be interested in talking to local suppliers of lithium feedstocks. According to the Sun’s sources, developing lithium mines in the US is a lengthy process taking as much as 10 years, while lithium mining operations already located in Nevada are either too small or nearing the end of their planned lifetime.

Now up pops Nevada Sunrise Gold Corporation, which apparently is a played out gold mining operation. It announced on September 2nd that it has “entered into a letter agreement for an option to purchase” a site in Esmeralda County, which is in Nevada’s Clayton Valley. The company believes that area could hold lithium brine deposits in subterranean aquifers, based upon studies and reports made of the local area.

Meanwhile, researchers at the University of Wyoming report they have discovered an enormous supply of lithium at the Rock Springs Uplift, a geological feature in southwest Wyoming. Initial tests indicate the lithium-rich brine from a 25-square-mile area could contain 228,000 tons of the stuff. That’s enough to meet annual U.S. demand and is twice the amount available at Silver Peak in Nevada, which is the biggest domestic lithium producer today.

What has the University of Washington team excited is that the lithium at the Rock Springs Uplift can be processed more cheaply than the lithium found at other locations, due to a number of factors.

First, extracting the lithium from brine requires large quantities of soda ash (sodium carbonate). The Rock Springs Uplift site is located within 30 miles of the world’s largest industrial soda ash supplies, so the cost of transporting it to the production area will be minimal.

Second, magnesium must be removed from brine before it can be used for lithium recovery and that can be an expensive process. The brine from the Rock Springs Uplift reservoirs is lower in magnesium than at other sites. Less magnesium means less money to remove it.

Third, the brine must be heated and pressurized to release the lithium it contains. Because the Rock Springs Uplift brine is far underground, it is already at a higher pressure and temperature than brine at existing lithium operations. That factor may eliminate an expensive step in the process, resulting in significant cost savings.

The Chinese thought they had cornered the market for lithium when they locked up rights to much of the world’s lithium supply located in Bolivia a decade ago. But apparently, the demand has created interest in new sources of supply. Hopefully, all this interest in lithium will spur competition which could lead to lower prices. And that could spell lower battery prices for the electric cars and electrical storage batteries of the future.

Tesla made napping in a Robotaxi easier with its latest update

Tesla’s quiet mode reaches Model Y Robotaxis, blacking out the screen for riders wanting rest.

Tesla’s quiet mode, the setting that blacks out the screen for riders who want to rest, has moved beyond the Cybercab. A video posted Thursday by Spencer (@scotsrule08) shows the feature running in a Model Y Robotaxi on a night ride that appears to be in Dallas.

The rider taps a small crescent moon icon in the bottom right corner of the map screen. The map, media player, app shortcuts and Grok prompt disappear, leaving a dark display with “Arriving soon,” the destination and a line reading “Tap display to exit quiet mode.” Controls a passenger may still need, including Pull Over, cabin temperature, volume and Support, stay visible. One tap anywhere brings the full map back.

Quiet mode first showed up in the Cybercab last week, which Teslarati reported alongside a new rear camera view. Tesla has been trimming cabin noise in other ways too. On October 25, Spencer reported that Robotaxi turn signals now chime for the first four blinks and then go silent. Tesla has not published release notes for either change.

Elon Musk has been pitching this use for more than a decade. In October 2014, he said that “maybe five or six years from now I think we’ll be able to achieve true autonomous driving where you could literally get in the car, go to sleep and wake up at your destination,”

By 2017 he was setting a higher bar. Speaking at TED, Musk said the hard part was not making self-driving work 99.9 percent of the time, “because, like, if a car crashes one in a thousand times, then you’re probably still not going to be comfortable falling asleep. You shouldn’t be, certainly.”

Owners asked for something similar in their own cars. In December 2019, a Tesla owner requested a Nap Mode that would keep the climate running and wake the occupant with an alarm, and Musk answered “Ok,” as Teslarati covered at the time.

The line returned when the Cybercab was unveiled at the We, Robot event in October 2024. “We’ll move from supervised Full Self-Driving to unsupervised Full Self-Driving, where you can fall asleep and wake up at your destination,” Musk said. On Tesla’s first quarter earnings call in April 2025, he called it the deciding measure: “The acid test is, can you go to sleep in your car and wake up in your destination and I’m confident that will be available in many cities in the US by the end of this year,”

Tesla has run driverless Model Y rides in Dallas and Houston since April, so a passenger dozing off on the way home is now a realistic use of the button. Tesla is also offering new riders a free first trip in both cities, according to an in-app screen shared by tracker Ethan McKanna, and said on its third quarter call that Cybercab rides would launch in Dallas next month.

FCC green lights SpaceX’s move to a showdown with Verizon and AT&T

The FCC advanced plans opening 482 MHz to satellite phone service, boosting SpaceX’s Starlink Mobile.

Published

A hand holds a smartphone displaying the Starlink Mobile app interface showing a strong “Connected – Direct to Cell” signal, with a Starlink satellite beaming connectivity signals down to Earth from orbit. The background features the planet’s night side glowing with city lights against the curve of the atmosphere, set above a scenic twilight landscape.

The Federal Communications Commission voted Thursday to move forward with a proposal that would open an additional 482 MHz of spectrum to satellite service beamed directly to ordinary phones, a step that could widen the road for SpaceX’s Starlink Mobile to compete with the country’s largest wireless carriers.

The commission adopted the notice of proposed rulemaking at its October open meeting in Washington, Reuters reported. The proposal would raise the number of bands eligible for Supplemental Coverage from Space from five to 13, according to the FCC fact sheet. Commissioners also advanced a companion item proposing an auction of 25 MHz in the 1675 to 1695 MHz and 2020 to 2025 MHz bands, which could be used for terrestrial service, direct to device service or both.

Thursday’s vote does not hand any spectrum to SpaceX. It opens a public comment period, and final rules will come later. Under the draft, comments would be due 60 days after the notice is published in the Federal Register. The FCC had not released the adopted text at the time of writing, so it is not yet clear whether any bands were changed before the vote.

That question is where the fight now moves. AT&T, Verizon and T-Mobile, through industry group CTIA, asked the FCC to drop the 2.5 GHz and 3.45 GHz bands, which make up 290 MHz of the 482 MHz on the table, as Teslarati reported ahead of the vote. T-Mobile argued satellite interference could wipe out up to 96% of a cell site’s uplink coverage area. SpaceX asked the commission to go the other way and add the 902 to 928 MHz band.

The rule change that matters most to SpaceX may be a structural one. Today, a satellite operator must lease spectrum from every carrier holding co-channel licenses across an entire region such as the contiguous United States. The proposal would replace that with a certification that the operator has coexistence agreements covering only the areas it plans to serve, or that it holds the terrestrial licenses itself.

SpaceX has spent this year building that second path. It bought EchoStar’s AWS-4 and H-block licenses in a deal worth roughly $17 billion, and earlier this month agreed to acquire Grain Management’s nationwide 800 MHz portfolio, which the company said would pave the way for Starlink to become a major US mobile carrier. The FCC approved SpaceX’s purchase of three unused AWS-3 licenses from Tristar on October 21, and cleared its plan for 15,000 next generation direct to cell satellites on October 6.

The regulator has not always sided with SpaceX. In April, the FCC dismissed a SpaceX petition seeking access to Mobile Satellite Service spectrum held by incumbents, and it rejected 2.5 GHz for satellite coverage when it first adopted the framework in 2024.

The carriers are also building their own defenses. In May, the three companies agreed in principle to form a joint venture pooling spectrum for satellite service, and T-Mobile remains SpaceX’s US launch partner for Starlink Mobile even as it leads the push to keep satellites out of 2.5 GHz. SpaceX President Gwynne Shotwell has said service on SpaceX’s own airwaves is targeted for early 2028.

Tesla’s Roadster appearance at SpaceX has merger watchers talking

Tesla’s next generation Roadster was spotted at SpaceX’s Hawthorne headquarters, two weeks after its unveiling.

Tesla’s next generation Roadster turned up at SpaceX’s headquarters in Hawthorne, California on Wednesday, less than two weeks after the car flew off a ramp at its unveiling in Texas.

Photos shared on X by SpaceX Engineer (@DeannaRiceSPCX) show the new Roadster parked outdoors beside the famed Falcon 9 that stands outside company headquarters at the corner of Crenshaw Boulevard and Jack Northrop Avenue. Rocket B1019 was the first orbital-class booster ever to land after a launch on December 21, 2015 after it sent 11 Orbcomm satellites to orbit and then flew back to Landing Zone 1 at Cape Canaveral, which would be the first landing in what became SpaceX’s reusable rocket program. SpaceX chose not to fly it again. After a test fire in Florida, the booster was shipped to Hawthorne and raised upright as a permanent monument in August 2016, as Teslarati reported at the time. Putting the Roadster, which flies on SpaceX cold gas thrusters, next to the rocket that started SpaceX’s landings is symbolic in itself.

The Thrust and Rocket versions of the Roadster use cold gas thrusters fed by composite overwrapped pressure vessels, the same type of tank SpaceX flies on Falcon 9, and Elon Musk described the car as the work of Tesla and SpaceX engineers working together. Tesla lists 0 to 60 mph in under 0.9 seconds for Thrust and under 0.59 seconds for Rocket, while the base Performance model relies on a fan and ground sealing system for grip, as Teslarati detailed in its breakdown of the three Roadster configurations.

Tesla has kept the car in the spotlight since the October 15 event near Waco. Last week, the company posted a video of the Roadster’s fighter jet inspired cockpit, including a Track Mode screen with a “Thruster · 5,500 PSI” readout, which we covered in our look at the Roadster’s center display. Musk also said owners will be able to ask the car to perform the stunts autonomously, and promised a looping track at Tesla’s Texas headquarters.

The visit comes as special committees at Tesla and SpaceX weigh a possible merger, a step Musk confirmed on SpaceX’s third quarter earnings call. The Roadster, built on SpaceX hardware, has become one of the clearest examples of the two companies already building products together.

Musk said at the unveiling that Roadster production will begin in 2028. Reservations are open with a $50,000 payment, Thrust is listed as a limited release and Rocket is invite only. Tesla says the car is not approved for public road use.
