SpaceX has responded to a critical report from CNBC alleging that it has repeatedly polluted waters in Texas this year. As per the private space company, the publication’s allegations about its launch operations in South Texas were factually inaccurate.
In its report, CNBC alleged that SpaceX violated environmental regulations by “repeatedly releasing pollutants into or near bodies of water in Texas.” The publication cited a notice of violation from the Texas Commission on Environmental Quality (TCEQ) about SpaceX’s water deluge system at Starbase, Texas, as part of its sources for its article.
The TCEQ reportedly received a complaint alleging that SpaceX “was discharging deluge water without TCEQ authorization” on August 2023. A total of 14 complaints alleging environmental impacts from Starbase’s deluge system have reportedly been received by the Harlingen region, the publication noted.

In its response, which was posted through its official account on X, SpaceX noted that it worked with the TCEQ when Starbase’s water deluge system was built. SpaceX also clarified that it has only used potable water in the operations of Starship’s water deluge system.
Following is SpaceX’s full response to CNBC’s allegations.
CNBC’s story on Starship’s launch operations in South Texas is factually inaccurate.
Starship’s water-cooled flame deflector system is critical equipment for SpaceX’s launch operations. It ensures flight safety and protects the launch site and surrounding area.
Also known as the deluge system, it applies clean, potable (drinking) water to the engine exhaust during static fire tests and launches to absorb the heat and vibration from the rocket engines firing. Similar equipment has long been used at launch sites across the United States – such as Kennedy Space Center and Cape Canaveral Space Force Stations in Florida, and Vandenberg Space Force Base in California – and across the globe.

SpaceX worked with the Texas Commission of Environmental Quality (TCEQ) throughout the build and test of the water deluge system at Starbase to identify a permit approach. TCEQ personnel were onsite at Starbase to observe the initial tests of the system in July 2023, and TCEQ’s website shows that SpaceX is covered by the Texas Multi-Sector General Permit.
When the EPA issued their Administrative Order in March 2024, it was done without an understanding of basic facts of the deluge system’s operation or acknowledgement that we were operating under the Texas Multi-Sector General Permit.
After we explained our operation to the EPA, they revised their position and allowed us to continue operating, but required us to obtain an Individual Permit from TCEQ, which will also allow us to expand deluge operations to the second pad. We’ve been diligently working on the permit with TCEQ, which was submitted on July 1st, 2024. TCEQ is expected to issue the draft Individual Permit and Agreed Compliance Order this week.
Throughout our ongoing coordination with both TCEQ and the EPA, we have explicitly asked if operation of the deluge system needed to stop and we were informed that operations could continue.
TCEQ and the EPA have allowed continued operations because the deluge system has always complied with common conditions set by an Individual Permit, and causes no harm to the environment.
Specifically:
– We only use potable (drinking) water in the system’s operation. At no time during the operation of the deluge system is the potable water used in an industrial process, nor is the water exposed to industrial processes before or during operation of the system.
– The launch pad area is power-washed prior to activating the deluge system, with the power-washed water collected and hauled off.
– The vast majority of the water used in each operation is vaporized by the rocket’s engines.
– We send samples of the soil, air, and water around the pad to an independent, accredited laboratory after every use of the deluge system, which have consistently shown negligible traces of any contaminants. Importantly, while CNBC’s story claims there are “very large exceedances of the mercury” as part of the wastewater discharged at the site, all samples to-date have in fact shown either no detectable levels of mercury whatsoever or found in very few cases levels significantly below the limit the EPA maintains for drinking water.
– Retention ponds capture excess water and are specially lined to prevent any mixing with local groundwater. Any water captured in these ponds, including water from rainfall events, is pumped out and hauled off.
– Finally, some water does leave the area of the pad, mostly from water released prior to ignition and after engine shutdown or launch. To give you an idea of how much: a single use of the deluge system results in potable water equivalent to a rainfall of 0.004 inches across the area outside the pad which currently averages around 27 inches of rain per year.
With Starship, we’re revolutionizing humanity’s ability to access space with a fully reusable rocket that plays an integral role in multiple national priorities, including returning humans to the surface of the Moon. SpaceX and its thousands of employees work tirelessly to ensure the United States remains the world’s leader in space, and we remain committed to working with our local and federal partners to be good stewards of the environment.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.
Tesla wireless charging patent revealed ahead of Robotaxi unveiling event
However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
