Lithium Mining is a Hot Topic In Nevada Thanks to Tesla
Lithium mining is suddenly a hot topic in Nevada, where a local state senator is up in arms about a deal to import lithium from Mexico. Other sources exist.

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.
@ScottLucasNV Lithium deal is not exclusive & has many contingencies. The press on this matter is unwarranted.

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 has a Cybercab problem nobody saw coming
Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.
Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”
Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.
The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.
Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.
The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.
Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
