Elon Musk’s Boring Co. to build concrete batch plant for tunnel “rings”
Elon Musk’s tunneling startup, The Boring Company, will use custom concrete rings for its tunneling projects. According to a request for tax exclusion that the company submitted to the California Alternative Energy and Advanced Transportation Financing Authority last December, the Boring Co. tunnels will use a type of concrete that is superior to the industry standard.
As stated in the company’s documents, The Boring Company intends to build a batch plant and a carousel system to manufacture and transport concrete rings — tunnel walls made up of multiple segments that are linked together. The tunneling startup expects that the rings it will be producing would be able to withstand earthquakes and over 100 years of continuous use.
The Boring Company noted that it would utilize “advanced materials” to manufacture its tunnels’ concrete walls. The concrete that the company intends to produce would be durable as well, with the startup stating that the segments are expected to reach strengths in excess of 6,500 pounds per square inch.
Apart from this, the startup’s concrete also has a setting time of just 1-7 days, substantially shorter than the industry standard of 28 days. The Boring Company further noted that the concrete it would be using is formulated in a way that would make the segments incredibly dense, making the Boring Co.’s rings less permeable and more resistant to corrosion.
The concrete rings for the Boring Company tunnels are only as effective as the machine that makes and sets them, however. In this light, the tunneling startup stated that it would be using a fully-automated carousel system that is designed to transport and set the concrete rings without human intervention.
-->“The system used to produce the concrete rings has been customized by The Boring Company, and the company represents that it is the world’s first fully-automated carousel system. This equipment requires precise engineering and will allow for higher precision and speeds than what is currently on the market, according to the TBC.
“Additionally, the fully-automated carousel will enable the production and transportation of the rings without human intervention, but The Boring Company represents that the process will still be monitored by staff for safety and quality from a control center. TBC represents this carousel system, and the specialized moulds will produce rings that are lighter than standard concrete rings, while maintaining their strength.”
The document also revealed that The Boring Co. would be making the manufacturing facility of the concrete rings fully electric. Apart from being more environmentally-friendly than conventional systems that use fossil fuels, an all-electric manufacturing process for the company’s concrete segments is expected to result in a 20% decrease in energy consumption.
The Boring Co. expects to purchase the property for its batch plant within the next 12 months.
While only a year old, the Boring Company has taken some considerable strides this year so far. Just recently, we reported on the startup raising $113 million in a funding round. The startup has also managed to take a step forward in its efforts to build a 2.7-mile proof-of-concept tunnel under Sepulveda Boulevard in West LA and Culver City, with the LA City Council Public Works Committee exempting the company from environmental review under the California Environmental Quality Act (CEQA).

SpaceX’s Starship program is already bouncing back from Booster 18 fiasco
Just over a week since Booster 18 met its untimely end, SpaceX is now busy stacking Booster 19, and at a very rapid pace, too.
SpaceX is already bouncing back from the fiasco that it experienced during Starship Booster 18’s initial tests earlier this month.
Just over a week since Booster 18 met its untimely end, SpaceX is now busy stacking Booster 19, and at a very rapid pace, too.
Starship V3 Booster 19 is rising
As per Starbase watchers on X, SpaceX rolled out the fourth aft section of Booster 19 to Starbase’s MegaBay this weekend, stacking it to reach 15 rings tall with just a few sections remaining. This marks the fastest booster assembly to date at four sections in five days. This is quite impressive, and it bodes well for SpaceX’s Starship V3 program, which is expected to be a notable step up from the V2 program, which was retired after a flawless Flight 11.
Starship watcher TankWatchers noted the tempo on X, stating, “During the night the A4 section of Booster 19 rolled out to the MegaBay. With 4 sections in just 5 days, this is shaping up to be the fastest booster stack ever.” Fellow Starbase watcher TestFlight echoed the same sentiments. “Booster 19 is now 15 rings tall, with 3 aft sections remaining!” the space enthusiast wrote.
Aggressive targets despite Booster 18 fiasco
SpaceX’s V3 program encountered a speed bump earlier this month when Booster 18, just one day after rolling out into the factory, experienced a major anomaly during gas system pressure testing at SpaceX’s Massey facility in Starbase, Texas. While no propellant was loaded, no engines were installed, and no one was injured in the incident, the unexpected end of Booster 18 sparked speculation that the Starship V3 program could face delays.
-->Despite the Booster 18 fiasco, however, SpaceX announced that “Starship’s twelfth flight test remains targeted for the first quarter of 2026.” Elon Musk shared a similar timeline on X earlier this year, with the CEO stating that “ V3 is a massive upgrade from the current V2 and should be through production and testing by end of year, with heavy flight activity next year.”
Considering that Booster 19 seems to be moving through its production phases quickly, perhaps SpaceX’s Q1 2026 target for Flight 12 might indeed be more than feasible.

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
-->During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.
