Tesla’s ‘Roadrunner’ facility gets a neighbor working on tech beyond the million-mile battery
As the wait for Tesla’s Battery Day continues, more and more speculations are abounding about what the electric car maker might reveal during the highly-anticipated event. Elon Musk has stated that Battery Day’s announcements will be mind-blowing, and based on apparent clues recently observed by the Tesla community, it appears that the CEO may be right on the money.
Recent reports have indicated that Amprius, a battery company currently working on silicon nanowire tech, recently relocated its headquarters to a site that’s just a few hundred feet away from Tesla’s Roadrunner battery facility in Kato Road, Fremont. Considering the firm’s focus, its new headquarters’ rather convenient location, and Elon Musk’s previous references to the use of silicon in batteries, there seems to be a fair chance that Amprius’ move to Fremont may be more than a coincidence.
Amprius notes that it is working on creating silicon nanowires for battery anodes that dramatically improve battery weight and density. The company’s website notes that silicon generally has about 10x the capacity of graphite (carbon), but it has a big drawback in the way that it swells when it’s charged, causing the silicon to fracture. To address this, Amprius utilizes silicon nanowires, which keeps the silicon from fracturing and breaking apart even when it swells.
As noted by EV enthusiast and YouTube host Driving Delta, Elon Musk himself appears to be teasing the use of advanced silicon tech on Twitter last month. In one of his posts, Musk shared some lyrics of the song “Lithium” by Nirvana, whose refrain includes sections that state “I’m not gonna crack.” Granted, Musk may simply be trolling the Tesla community with his posts, but it should be noted that he also talked about the increasing use of silicon anodes five years ago.
“We’re shifting the cell chemistry for the upgrade battery pack to partially use silicon in the anode. This is just a sort of baby step in the direction of using silicon in the anode. We’re still primarily using synthetic graphite, but over time, we’ll be using increasing amounts of silicon in the anode,” Musk noted during a 2015 conference call.
As noted by Amprius’ on its website, the use of 100% silicon paves the way for batteries with the highest energy density, perhaps even at the 500 Wh/kg level. That’s enough to start exploring electric VTOL projects, a topic that Elon Musk has admitted is something that truly interests him. That being said, Professor in Energy Materials and Technologies Ying Shirley Meng, who has made significant contributions to Maxwell Technologies’ battery tech herself, believes that challenges still remain in the use of silicon nanowires.
“We should pay attention to the cost per kg. Even (if) those nanowires work (which I doubt), to produce consistent quality in metric ton scale at 10$ per kg it will be sci-fi for now,” she noted.
Elon Musk, for his part, recently stated that the technology that could allow 400 Wh/kg with a high life cycle and volume production is not too far away. Musk gave a rough timeframe for the technology, stating that such milestones could be achieved in about three to four years.
Tesla’s Battery Day event is expected to introduce the company’s next-generation lithium-ion cells, though speculations suggest that these batteries — which are expected to last a million miles — are based largely on Maxwell Technologies’ dry electrode tech. Maxwell itself has previously noted that it could offer batteries with 300 Wh/kg while stating that it had also identified a path to 500 Wh/kg. With this in mind, it appears that Tesla may already be setting the stage for cells that will likely go even beyond the million-mile battery.
Granted, Amprius’ move to Fremont may be unconnected to Tesla. That being said, the two companies’ goals to align with each other, and Elon Musk’s own references to the use of silicon suggests that Tesla will likely get a lot of value from Amprius’ tech. If speculations prove true, the path to batteries that go even further than the million-mile mark may be feasible in the near future. Such innovations are key to Tesla’s goal of accelerating the transition to sustainable energy, after all.

Florida Governor Ron DeSantis has sharply criticized legacy media outlets for what he describes as selective and biased reporting on vehicle accidents involving Tesla. In a recent X post, DeSantis questioned why headlines routinely spotlight the Tesla brand in crash stories, even when human error is the clear cause, while similar incidents with other automakers often receive generic treatment.
A prime example is the June 19, 2026, fatal crash in Katy, Texas. A Tesla Model 3 driven by Michael Butler struck a brick home at high speed, killing 76-year-old Martha Avila inside. Initial reports and headlines prominently featured “Tesla crash” and referenced the driver’s claim that an automated driving-assistance system was engaged.
Many outlets quickly speculated that Full Self-Driving or Autopilot were the cause of the crash, immediately blaming the suites for the accident shortly after it happened.
However, Tesla responded shortly after the accident with vehicle data that showed Butler manually overrode the system by pressing the accelerator to 100 percent, reaching 73 MPH in a residential area, more than double the speed limit. The accelerator remained floored after impact.
Tesla finally clarifies fatal Texas crash, confirms driver manually overrode acceleration
The National Transportation Safety Board (NTSB) later confirmed these findings, and Butler now faces manslaughter charges. His phone searches also included queries like “Tesla FSD too timid,” suggesting he may have intervened aggressively. Despite this, many headlines continued to center Tesla’s technology rather than the driver’s actions.
DeSantis highlighted a Washington Post headline, which was labeled, “Newly released photo shows wreckage of Tesla crash that killed grandmother.”
Do legacy media outlets typically use headlines involving the make of a car in a crash or is that only for Tesla?
It would be one thing if the self-driving malfunctioned but the crash was purely human-induced.
Seems like these outlets want to associate Tesla with crashes as… pic.twitter.com/EmfyeYiuv6
— Ron DeSantis (@RonDeSantis) July 17, 2026
The subheadline noted the driver overrode assistance and floored the accelerator, yet the brand name dominated the framing. He asked whether legacy outlets typically name the make of a car in routine crashes or reserve that treatment for Tesla to push a narrative.
This pattern appears widespread. Crashes involving Ford, Chevrolet, or Toyota vehicles frequently appear as “pickup truck slams into home” or “fatal car crash kills pedestrian” without brand specifics, especially absent new technology angles.
High-profile Ford F-150 or Chevy Silverado incidents tied to large sales volumes often escape brand-callout scrutiny. In contrast, Tesla stories consistently lead with the manufacturer, amplifying perceptions of risk despite data showing strong overall safety performance:

Tesla’s own 2025 Impact Report indicates vehicles using FSD logged 0.19 major incidents per million miles, roughly eight times fewer than the U.S. average. Models like the Model Y also rank among the safest in IIHS and NHTSA testing for occupant protection. Critics argue disproportionate coverage ignores these statistics and driver behavior factors, such as younger or more aggressive Tesla owners in some studies.
DeSantis frames this as part of a broader political agenda against innovative American companies like Tesla. By consistently naming Tesla while downplaying others, media outlets risk eroding public trust and shaping perceptions detached from the evidence of human error in most cases.
As autonomous technology evolves across the industry, consistent and factual reporting will be essential to separate real safety concerns from narrative-driven coverage.
Tesla entered two new markets this week by advancing its presence in Latvia (Europe) and officially launching operations in Uruguay (South America), marking a rapid dual-continent expansion.
These moves underscore the company’s strategy to tap into emerging EV markets with supportive policies, renewable energy grids, and growing demand for sustainable transport.
Latvia: Strengthening the Baltic Footprint
In Latvia, Tesla has built on its earlier registration of Tesla Latvia SIA in late 2025 with recent steps toward full operations, including job postings for a service center and representation in Riga. This aligns with broader Baltic expansion following Lithuania’s model of pop-up stores and service centers.

— Tesla Europe, Middle East & Africa (@teslaeurope) July 17, 2026
EV penetration in Latvia stands at around 7 percent for BEVs in new passenger car registrations. 2025 data showed 1,602 BEVs out of about 22,500 total, or 7.1 percent, with combined plug-ins nearing 19 percent. Growth has been steady but below the European average, supported by government subsidies and infrastructure development. Tesla models like the Model 3 lead local EV registrations.
Vehicles for the Latvian market will likely be sourced from Gigafactory Berlin or Gigafactory Shanghai. Charging infrastructure is robust for the region as well, with over 400- 2,000 public points, with Tesla Superchargers in Riga, Jūrmala, and along Via Baltica routes offering up to 250 kW.
Uruguay: Third South American Country
Tesla teased its Uruguay arrival with “Estamos llegando,” or, “We are arriving,” on social media, followed by an official presentation scheduled for mid-July.
Hola Uruguay 🇺🇾
Nuestros Model 3 y Model Y están cada vez mas cerca! pic.twitter.com/FR41fsA7um

The company established Tesla Uruguay SAS, homologated Model 3 and Model Y (three versions each), and appointed local leadership. This makes Uruguay Tesla’s third official South American market after Chile and Colombia.
Uruguay boasts one of Latin America’s highest EV penetrations, with battery-electric vehicles exceeding 20 percent market share recently, driven by tax incentives, high fuel prices, and a nearly 95-100 percent renewable electricity grid. Hundreds of Teslas already operate via grey imports, but official sales bring warranties, service, and support.
Vehicles will be imported from Gigafactory Shanghai, enabling competitive pricing for Model 3 and Model Y. Charging plans include Supercharger development alongside existing infrastructure, leveraging the country’s green energy advantage for affordable operation.

Tesla’s Dual Continent Expansion
Tesla’s simultaneous push into Latvia and Uruguay demonstrates efficient scaling: prioritizing service and infrastructure first, then direct sales in high-potential niches. In Europe, it fills Baltic gaps; in Latin America, it counters Chinese dominance while leveraging renewables.
This dual move signals Tesla’s ambition to accelerate global EV adoption amid varying regional paces. By addressing local needs, like subsidies in Latvia or incentives and green grids in Uruguay, Tesla not only boosts volumes but advances its mission of sustainable energy.
For investors and consumers, it highlights resilience and opportunity in diverse markets, potentially paving the way for further growth in underserved regions. With strong fundamentals in both, these entries could yield long-term gains as EV transitions mature worldwide.
SpaceX has announced a new target date for the thirteenth test flight of Starship: Monday, July 20, with the launch window opening at 6:45 p.m ET/5:45 p.m. CT.

CEO Elon Musk revealed that some of the engines on Starship did not start, which automatically triggers a launch abort. Two of the Raptor engines will be removed and replaced.
To be confident of a good flight, 2 Raptors will be removed & replaced. Most probable launch timing is early next week.

SpaceX officially announced the new launch window this morning.
Starship’s 13th test launch comes with a few new objectives, but SpaceX does not plan to attempt a catch of the booster, which it has done several times in the past.
For Starship’s Upper Stage, there are some adjustments to ensure engine reusability that will be assessed during the ascent, and 20 operational Starlink V3 satellites are also set to make their way into space. SpaceX also plans to attempt an in-space relight of a single Raptor engine, which is a critical demonstration for future orbital deorbit, refueling, and deep space maneuvers.
Ultimately, it will splash down in the Indian Ocean.
The continuous tests help SpaceX advance the Starship program toward eventual full reusability, operational Starlink V3 deployment, and future missions, which include NASA’s Artemis program.
