Tesla targets lower operating costs through new waste water treatment system patent
Tesla is arguably one of the most dynamic companies in the industry today, with its tendency to constantly innovate even after it reaches its ambitious targets. This particular culture was mentioned by Tesla’s President of Automotive Jerome Guillen in a recent interview with CNBC, when he stated that Tesla’s work, specifically in its batteries, continue to evolve over time. Elon Musk echoed this tendency on Twitter, stating that even Tesla’s vehicles like the Model S and X are partially upgraded every month “as soon as a new subsystem is ready for production.”
Such a culture is emblematic of Tesla. Such a culture is also reflected in a recently published patent for the company, which outlines a clever waste water treatment system that could pave the way for more cost savings in operational expenses. The patent is titled System for Regenerating Sodium Hydroxide and Sulfuric Acid from Waste Water Stream Containing Sodium and Sulfate Ions and was published on November 15.
Tesla notes in its patent description that “acid leaching performed through the addition of sulfuric acid and neutralization through the addition of sodium hydroxide” are common processes used in manufacturing. As a result of these processes, waste water containing high concentrations of sodium and sulfate ions produced, since sodium and sulfate ions are very soluble and are difficult to remove through conventional precipitation processes. Tesla notes that these factors could result in large quantities of waste water being disposed — a process that is both expensive and harmful for the environment.
In a conventional waste water treatment setup, three chambers separated by an anion exchange membrane (AEM) and a cation exchange membrane (CEM), as well as anodes and cathodes, are utilized. Tesla notes that the present system for waste water treatment leaves much to be desired, considering that the setup is not cost-effective at all.
“With the prior art system, not all of the sodium and sulfate ions are able to be removed from the waste water feed stream to produce the ‘treated’ water. This reduces recovery of acid/caustic, and also presents challenges when trying to reuse the “treated” water. This process becomes increasingly difficult as the concentration of ions in the waste water feed stream lowers as it moves through the electrolysis treatment system, and an increasing amount of electrical voltage needs to be applied.
“Further, the generated acid/caustic products can only be produced at low concentrations. As the product streams increase in concentration, an increasing amount of electrical voltage is needed between the anode and the cathode. Further, as the membranes AEM and CEM are in contact with these higher concentration acid/caustic products, the lifetime of the membranes and decreases. The combination of a high electrical load, low recovery efficiency, low recovered acid/caustic concentrations, and short component lifetimes make the prior art system economically unviable.”
Tesla’s waste water treatment system utilizes membrane concentration systems as a cornerstone to develop a system where waste water is treated and possibly even reused. The electric car maker describes its system in the following description.
“As compared to prior waste water treatment systems, the waste water treatment system of the present disclosure uses the three dedicated membrane concentration systems to maintain high ion concentrations in the feed and low ion concentrations in the product chambers. The first thermal concentration system takes in the dilute acid produced by the electrolysis treatment system that allows pure water to permeate while the dissolved acid species are rejected. The pure water is recycled back to the second chamber of the electrolysis treatment system to dilute this stream, while the reject concentrated acid is extracted as a product.
“The second thermal concentration system takes in the dilute caustic produced by the electrolysis treatment system and allows pure water to permeate while the dissolved caustic species are rejected. The pure water is recycled back to the third chamber of the electrolysis treatment system to dilute this stream, while the reject concentrated caustic is extracted as a product. The membrane concentration system takes in the existing waste water that still contains significant dissolved sodium and sulfate. Pure water is extracted as a product, and the concentrate reject is sent back to the electrolysis treatment system waste water feed to maintain a high concentration of sodium and sulfate ions in the waste water feed.”
With such a system in place, Tesla expects to see optimizations in its operations. The Silicon Valley-based carmaker noted in its patent that its waste water treatment system would likely even extend the lifetime of components such as the AEM and CEM, resulting in more cost savings.
“The waste water treatment system of the present disclosure has significant operational advantages, including resulting in large positive driving concentration gradient assisting electric voltage, as opposed to negative gradient resisting electric voltage in (a) conventional system, dramatically reducing electrical load. The waste water treatment system allows for the AEM and CEM of the electrolysis treatment system to be in contact with low concentration acid/caustic, significantly increasing their lifetimes.
“Further, the produced acid/caustic from the membrane concentration systems are at much higher concentrations than the electrolysis treatment system could make on its own, increasing their value. Moreover, the exiting pure water product is Reverse Osmosis (RO) quality and can be directly used to service pure water needs. The recovery of both sodium and sulfate ions is near 100%, since there are almost no remaining ions in the exiting pure water product.”
Over the past months, published patents from the company show that Tesla is looking to optimize several aspects of its operations. Included among these is a rigid structural cable that could open the gates for more automation, a flexible clamping assembly that would allow the company to easily address panel gaps, as well as a DCM recovery system that could make battery manufacturing safer.

xAI supercomputer faces pushback from Memphis politicians
Local leaders in Memphis warn Elon Musk’s xAI hub could pollute local communities, despite Tesla Megapacks now stabilizing power.

xAI’s supercomputer in Memphis faces pushback from local leaders and environmental groups over concerns about air pollution despite its promise of economic growth.
xAI’s Memphis facility was touted as the world’s largest supercomputer. It has sparked opposition from the NAACP, Sierra Club, and Mississippi Democratic Party Chairman Cheikh Taylor.
State Rep. Taylor spoke at a Southaven church press conference recently, arguing that the xAI facility in Memphis, Tennessee, would disproportionately harm black residents in north Mississippi.
“In the State of Mississippi, the goal is to separate Republicans and Democrats on race alone. So, if you’re a Democrat in this state, you probably look like me,” Taylor said.
He also criticized prioritizing economic gains over environmental health, asking, “Can you trust Elon Musk to tell the truth?”
Tennessee State Rep. Justin J. Pearson echoed these concerns, linking the opposition to a broader fight against pollution. “The paltry money xAI has dangled in front of our short-sighted leaders is not worth the cost of breathing dirty and–in some cases–deadly air,” Pearson said.
These local leaders and environmental groups are urging local governments and the Environmental Protection Agency to deny xAI’s air permit applications for 45 to 90 methane gas turbines in the Memphis and Southaven areas.
xAI has not directly addressed the criticism but has taken steps to power its Colossus supercomputer sustainably. Last month, the Greater Memphis Chamber announced that Tesla Megapack batteries would stabilize the facility’s power, with a new 150-megawatt electric substation completing its first construction phase.
“The temporary natural gas turbines that were being used to power the Phase I GPUs prior to grid connection are now being demobilized and will be removed from the site over the next two months,” shared the Chamber.
An additional 160+ Megapacks were delivered to xAI’s Memphis facility for the Colossus 2 data center within the same month.
Announced in June 2024, the xAI facility was hailed by Greater Memphis Chamber CEO Ted Townsend as the largest capital investment by a new-to-market company in Memphis history. Despite its economic promise, environmental concerns continue to fuel opposition, highlighting tensions between technological innovation and community health in the Deep South’s emerging AI hub.

Elon Musk reveals date of Tesla Robotaxi’s first rides open to public
Tesla CEO Elon Musk continues to roll out new details regarding the Robotaxi launch that is expected to happen soon.

Tesla Robotaxi is set to launch in the coming days, but the first rides will be confined to those who receive invitations that the company sends out. However, CEO Elon Musk revealed the date that Tesla is aiming for when anyone in the general public will be able to call for a Robotaxi.
There has been quite a bit of information today about what appears to be an imminent launch of the Robotaxi platform. The first video of a Robotaxi was captured on a public road in Austin today, just one day after Tesla was added to the City of Austin’s list of licensed autonomous vehicle operators.

In the coming days, it is expected that Tesla will launch the Robotaxi platform in Austin to a select few. For now, Tesla is taking this ultra-conservative approach as it pertains to the rollout, citing safety precautions. It will be the first time Tesla has done this in public and offered it to people outside of the company.
It did launch a small, limited version of it to employees last month in Austin and the San Francisco Bay Area, but there was someone in the driver’s seat. Today’s video only had an occupant in the passenger seat.
People are eager to know: when will they be able to fetch a driverless Tesla Model Y Robotaxi in Austin for themselves? Musk finally answered the long-awaited question with a tentative date of June 22:
🚨 BREAKING: Elon Musk confirms public Robotaxi rides will tentatively begin on June 22
Safety remains the ultimate priority for Tesla with this cautious rollout https://t.co/Mw5kOzA9Sm

Musk cited that Tesla’s utmost priority is still safety and not necessarily the speed of rollout. The current plan seems to be to deploy it in a controlled and slow fashion until confidence is at an extremely high level. Musk seems to believe the rollout will go smoothly, as the date comes less than two weeks after the initial launch.
Anyone who has experienced Full Self-Driving for themselves knows what the cars are capable of. However, Tesla, at this point in time, still requires drivers to pay attention and remain ready to take over the wheel in case of an emergency. This will be a major step in the right direction for Tesla as it prepares to launch Robotaxi in Austin and slowly expand to surrounding areas.

Elon Musk says Tesla Robotaxi launch will force companies to license Full Self-Driving
“The automakers keep being told that this isn’t real or that just buying some hardware from Nvidia will solve it. As Tesla robotaxis become widespread and their other solutions don’t work, they will naturally turn to us.”

Tesla CEO Elon Musk says the automaker’s Robotaxi platform launch later this month will essentially force other companies to license Full Self-Driving to achieve their own goals of achieving autonomy.
Musk’s statement comes as a video captured today showed the first Tesla Robotaxi test mules on public streets in Austin, Texas, just one day after the City officially listed the company as an autonomous vehicle operator.
A prediction by investing YouTube and Tesla community member Dave Lee stated that “at least one automaker by end of year” will license Full Self-Driving from the Musk-led company, as it will give rivals the confidence to use the software to run their own self-driving operations.
Lee detailed his theory by stating that the company that chooses to commit to FSD licensing will not be able to integrate the hardware and sell those units immediately. Instead, it will take two years or so to solve the engineering and design applications.

Musk revealed his true thoughts on other automakers’ attempts at vehicle autonomy, and said many are being told that Robotaxi is not real or that they can solve their problems with hardware orders to Nvidia.
He went on to say that companies will be forced to turn to Tesla at some point or another, because Robotaxi will be widespread and their solutions to figuring out an effective deployment will prove to be failures:
“The automakers keep being told that this isn’t real or that just buying some hardware from Nvidia will solve it. As Tesla robotaxis become widespread and their other solutions don’t work, they will naturally turn to us.”

Musk has not been shy to respond to speculation regarding the video of the Robotaxi, which was shared on X earlier today. This is perhaps one of the more fiery things he revealed. He seems ultra-confident in what Tesla will prove and achieve in the near future with the launch of the Robotaxi platform.
Many believe it will be rolled out this month. Bloomberg reported recently that Tesla was internally aiming for June 12. The company has not directly responded to these rumors.
Tesla has discussed on several occasions that it is in talks with an automaker about licensing Full Self-Driving, but it has never revealed who. The company first revealed discussions with another automaker in early 2024 when Elon Musk said:
“We’re in conversations with one major automaker regarding licensing FSD. It really just becomes a case of having them use the same cameras and inference computer and licensing our software. Once it becomes obvious that if you don’t have this (FSD) in a car, nobody wants your car. It’s a smart car… The people don’t understand all cars will need to be smart cars, or you will not sell, or nobody would buy it. Once that becomes obvious, I think licensing becomes not optional.”
Tesla confirms it is in talks with major automaker for potential FSD licensing
Many, including us, suspected that Ford was the company that Tesla was speaking of due to Musk’s relationship with Jim Farley, which resulted in the legacy automaker being the first major car company to adopt Tesla’s North American Charging Standard (NACS), which gave them access to the Supercharging Network.
This catalyzed an onslaught of companies choosing to make the same move as Tesla had truly set itself apart in terms of charging infrastructure.
Companies may be forced to make a similar decision if it can make the same type of statement with the rollout of Robotaxi.
