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 makes good on its Cybercab promise in just two weeks

Tesla Cybercab riders can now pull up a rear camera view and darken the screen.

Tesla has given Cybercab passengers a way to see what is behind them, along with a way to turn the cabin screen off entirely.

Riders in Austin can now bring up a live rearview camera feed on the Cybercab’s center display in the middle of a trip. Austin rider Ethan McKanna spotted the change late Friday night, posting from a ride that “You can now open the camera to view what’s behind you in Cybercab!” His photo shows a strip of rear camera video across the top of the screen, with another Cybercab following on a bridge. Sawyer Merritt shared the image Saturday and wrote that it “sounds like” there is also a new quiet mode that darkens the entire screen for riders who want to relax, sleep, or avoid a bright display at night.

The camera view goes beyond the rear feed. Tesla UI software engineer Evan, who posts as @CarCoder, replied to McKanna with a tip: “You can also tap it to see more cameras, and swipe it up or down to hide and show.” Until now, the Cybercab only showed its rear and repeater feeds on the “Please Exit Safely” screen at the end of a ride, so passengers could check for cyclists and traffic before opening a door.


Quiet mode surfaced a day earlier. Austin rider Jackson Blatz posted a video Friday morning of the new Robotaxi interface in a Cybercab with the option. Tesla has not published release notes for either feature.

The rear camera view moved quickly from request to release. Earlier this month, Cybercab rider Dan Burkland asked Tesla to let passengers pull up the rear and repeater cameras whenever they want, “especially for peace of mind.” Evan answered “In development,” as Teslarati reported at the time. About two weeks later, riders have it.

The feature fills a gap created by the Cybercab’s design. With no steering wheel, no pedals, no mirrors and no rear window, a passenger has no natural way to glance behind the car. The eight exterior cameras that feed Tesla’s autonomy software were already on board, so the change only required software.

There is also an AI angle to how it was built. Yun-Ta Tsai, a senior staff engineer on Tesla’s AI team, quoted Merritt’s post and wrote that the “(human) camera view tuning is optimized with Grok and implements part of the algorithm by directly programming the fixed-function hardware, so I don’t even need to check the datasheet.” Tsai did not say which part of the algorithm Grok handled. Grok already plays a bigger role inside the vehicle, with Grok Bot now enabled across every Cybercab and the Model Y Robotaxi fleet after Tesla brought the agent into its cars in September.

The two features join a busy week of changes for riders in Austin, which also brought a redesigned Live Activity for iPhone and Apple Watch and live trip sharing. They also arrive as Tesla prepares the Cybercab for life outside its own fleet. On the third quarter earnings call, Lars Moravy said the company is aiming to deliver Cybercabs to customers before the end of 2026. Tesla has not said whether the camera view and quiet mode will also come to its Model Y Robotaxis.

Tesla has given future owners their clearest look yet at the cockpit of its next generation Roadster. In a 34 second video posted to X on Friday afternoon, the company walked through the car’s touchscreen with a caption: “Inspired by fighter jet cockpits, Roadster’s interface was designed around the pilot.”

The clip opens on a black screen with red graphics and a 3D wireframe of the car, which sits beside the Roadster’s squared off yoke. Tapping parts of the model brings up controls for the rear wing, including low drag and high downforce positions, along with a charging page with a charge limit bar and a small music player. A row of tabs along the bottom reads Home, Vehicle, Listen, Climate and Navigate.

Most of the video is spent in Track Mode. The dashboard shows a live circuit map, a list of session lap times, brake and motor temperatures, and pressure and temperature readouts for each tire. A setup page lets the driver pick Auto, Low Drag, High Downforce or Custom aero modes, adjust aero balance and brake balance, and switch stability and traction control off. Along the bottom, a status bar reads “Thruster · 5,500 PSI” next to a “Boost Ready” indicator.

That gauge ties the software to the hardware Tesla showed off near Waco, Texas on October 15. The Thrust and Rocket versions use cold gas thrusters fed by carbon overwrapped pressure vessels, and Tesla lists 0 to 60 mph times of under 0.9 seconds and under 0.59 seconds for them, as Teslarati detailed in its breakdown of the three Roadster configurations. The base Performance car relies on a fan and ground sealing system for grip, and the aero settings on screen match the active wings and suction setup covered in our look at how the Roadster generates downforce.

The Roadster layout is a departure from the rest of Tesla’s lineup. Instead of a map centered screen, the Roadster puts the car itself at the center of the home page, and Tesla’s Roadster page lists two smaller forward displays alongside the main touchscreen. Tesla has not said whether any of the Track Mode telemetry will make its way to the Model 3 Performance or other vehicles.

The interface could still change before deliveries. Elon Musk said at the event that Roadster production will begin in 2028, and Tesla says the flagship Rocket version is not approved for public road use. Reservations are open with a $50,000 payment, while Thrust is listed as a limited release and Rocket is invite only.

Those who want to see the car in person will get their first chance this weekend. The Roadster goes on display in the lobby of the Petersen Automotive Museum in Los Angeles from October 24 to 27, according to Sawyer Merritt, the first time the public will be able to view it up close.

Tesla reveals Optimus Academy, where robots teach themselves

Tesla has begun building production quality Optimus robots in Fremont and revealed its training plan.

Concept rendering of Tesla Optimus in mass production

Tesla has started building Optimus on the high volume line it set up inside its Fremont factory, and the company says the robots coming off it are the first that meet the bar for a real product. “The bots coming off this line are the first production-quality bots that we have manufactured,” Tesla wrote in its third quarter shareholder letter, adding that it has “proven that the current manufacturing process for Optimus is suitable for a commercial product.”

The line sits in space that built the Model S and Model X until this spring. Tesla cleared the old vehicle line in 46 days, as Teslarati reported in July, to make room for robot production sized for one million units a year. On Wednesday’s earnings call, Elon Musk said most of the equipment for that capacity is already in Fremont, with output set to climb toward roughly 20,000 robots a week as the line ramps.

Musk described the ramp as a classic S curve. “The growth of Optimus is an S curve, but the initial curve is a shallow slope,” he said. The team is now refining the robot’s AI, electromechanical design, reliability and service life, and Musk expects that work to be finished by the end of next year, when Tesla plans to start delivering Optimus to outside companies for dangerous, repetitive and around the clock jobs.

The most interesting part of the call was how Tesla plans to teach the robots. Its cars send real driving data back to the AI team from millions of vehicles, but Optimus has no fleet like that yet. “A big difference with Optimus versus the cars is we don’t have this vast fleet of cars from which we can gather training data,” Musk said. Tesla’s answer is an Optimus Academy, where 10,000 to 20,000 robots will practice a wide range of tasks and feed what they learn into the next version of the model. Every unit off the Fremont line becomes a source of that training data.

Smarter hardware is on the way too. Tesla plans to put its AI5 chip into Optimus next year, and Musk said a new Optimus video should arrive within one or two months showing the robot completing tasks driven by AI rather than preprogrammed motions. He took aim at rival humanoid demos that only run scripted routines, saying those would not hold up in the real world.

The supply chain is lining up behind the program. In September, Tesla certified Tuopu, Joyson and Sanhua as mass production partners for Optimus components. A far larger Optimus factory is also rising at Giga Texas, where drone footage from Joe Tegtmeyer showed the steel frame nearing completion, and Musk has pegged that plant’s long term target at 10 million robots a year.

Tesla executives also said Optimus production costs are trending toward the expected manufacturing cost of Cybercab, a sign the robot is being engineered for volume from the start. The hands remain the toughest piece of the design, a point Musk also made at the X Takeover event earlier this month, as Teslarati covered at the time, and that is where much of the current engineering effort is focused.
