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.

Ferrari’s first electric vehicle, the Luce, is fully sold out for 2027, according to CEO Benedetto Vigna.
Presenting third-quarter results, he stated: “Everything we plan to sell next year is already fully allocated. Client test drives, scheduled for next year, will help further boost demand. We have no critical issues, neither on manufacturing nor on the demand side. Obviously, the car is more complex because it has many new parts and many new technologies.”
First customer deliveries are expected before the end of 2026, with the model already commanding waitlists despite a turbulent debut.
The Luce is a five-seat, four-door liftback saloon—the longest Ferrari ever produced—powered by four electric motors producing approximately 1,035 horsepower.
It features an 800-volt architecture, a 122-kWh battery, a claimed WLTP range of around 329 miles, 0-62 mph acceleration in 2.5 seconds, and a starting price near €550,000 in Europe (roughly $560,800–$615,000 in the U.S. depending on configuration).
Developed in collaboration with Jony Ive and Marc Newson’s LoveFrom studio alongside Ferrari’s own Centro Stile, it represents a deliberate departure from the brand’s traditional mid-engine sports cars toward a more spacious, grand-touring format.
Its exterior has proven deeply polarizing. Unveiled in Rome in May 2026, the design features smooth, sweeping surfaces, a large glass roof, and restrained detailing that critics described as bland, generic, or more reminiscent of an Apple product or mass-market EV than a Ferrari.
Ferrari unveils its Luce EV, and its reception has been a disaster
Online reactions included memes comparing it to a Nissan Leaf or Polestar, while former Ferrari chairman Luca di Montezemolo publicly warned of “the destruction of a myth” and suggested the prancing horse logo be removed. Italian politicians and longtime owners joined the chorus of disappointment, and Ferrari’s shares dropped roughly 8% in a single day, erasing billions in market value.
Design experts noted the absence of the brand’s signature tension, aggression, and emotional drama.
Yet the controversy has not translated into weak demand among the ultra-wealthy clientele who actually buy Ferraris. Production volumes remain tightly limited, as reports suggest fewer than 500 units in the current year and a longer-term pace of roughly 600 annually through 2030, preserving exclusivity.
One early chassis sold for $40 million at auction. Vigna has indicated that seeing the car in person, along with upcoming client test drives, is expected to strengthen rather than weaken interest. Ferrari aims for fully electric models to comprise 20 percent of its lineup by 2030, with a second EV now delayed to 2028.
For a brand defined by scarcity and desirability, the Luce’s sell-out status suggests that among those who can afford it, the polarizing design has not proven to be a commercial liability.
Tesla and SpaceX shares fell on Wednesday after Democrats swept both chambers of Congress. The decline stood out as broader market securities recovered and turned positive, while both of Musk’s publicly traded companies lagged.
CEO Elon Musk already joked about the unsuccessful campaigning for the Republicans, but now the new party will make pretty drastic changes to how it handles Tesla and SpaceX, and those companies will adjust their outlook.
Let’s take a deeper look.
Tesla ($TSLA)
Tesla shares traded lower during the regular session after Democrats secured both the House and Senate. The stock was down 2.32 percent at around 1:45 p.m. on the East Coast, trading at around $389.30.
The pressure is tied to more than the raw scale of Musk’s political spending, estimated at $450–474 million this cycle with roughly $224 million directed at Texas. In that state, Tesla now faces a Democratic governor and a Democratic senator after Gina Hinojosa unseated Greg Abbott and James Talarico defeated Ken Paxton.
The Austin Gigafactory, Robotaxi pilot programs in multiple Texas cities, and any related AI compute expansion sit under a new state executive who campaigned against certain corporate subsidies and floated a moratorium on new data-center construction.
Federally, Democratic control of key committees opens the door to deeper examination of Tesla’s autonomous-driving safety record, federal energy-storage and manufacturing incentives, and the national-security implications of any combination with SpaceX.
Investors are also weighing whether the company’s historically close alignment with the prior Republican leadership will invite slower permitting, additional hearings, or tighter rules on Full Self-Driving deployment.
For Tesla, the political shift adds near-term friction around state permitting and federal regulatory approvals for autonomy and energy storage. A potential merger with SpaceX may face slower review even if it proceeds.
Core growth drivers such as vehicle deliveries, energy deployments, and robotaxi rollout remain intact, yet the stock now carries a higher political-risk premium that could weigh on valuation until the company demonstrates workable relationships with the new Texas leadership and congressional majorities.
SpaceX ($SPCX)
SpaceX shares also declined in live trading on November 4 following the Democratic midterm sweep. The stock traded at $134.97, down 4.49 percent. The drop occurred even as broader indexes stabilized, highlighting a company-specific reaction to the election outcome.
Musk’s large contributions, concentrated in Texas races that both companies lost, place SpaceX’s Starbase launch facility and headquarters under a new Democratic governor.
At the federal level, Democratic control of Congress enables greater scrutiny of NASA, the Department of Defense, and other contracts that support a meaningful share of revenue, along with reviews of Starlink national-security uses and any Tesla merger. Analysts have noted that empowered committees can hold hearings and request documents on these relationships.
For SpaceX, the results raise the risk of delayed contract awards, higher compliance costs, and tighter constraints on AI and satellite infrastructure expansion, particularly in Texas where a data-center moratorium has been discussed.
A merger with Tesla could encounter political friction that slows integration of launch, connectivity, and autonomy capabilities.
While Starlink growth and launch cadence continue as primary drivers, the company faces a more contested path for federal funding and state-level operations, requiring management to rebuild ties with the new congressional majorities and Texas leadership to limit the overhang.
Tesla’s new vehicle registrations in Germany rose sharply in October, nearly quadrupling from the same month a year earlier. That’s according to data from the KBA, Germany’s federal motor transport authority.
The KBA reported 2,932 Tesla vehicles registered in October, a 290.9 percent year-over-year- increase. For the first ten months of the year, Tesla’s cumulative registrations reached 47,742 units. This number is up 206.1 percent compared with the January-October period of 2025. These gains occurred against a backdrop of strong overall growth in the BEV sector as a whole.
Germany registered 94,086 new BEVs in October, a 79.5 percent rise that brought the BEV share of the passenger car market to 37 percent of the 254,492 total cars registered that month.

Despite the percentage surge, Tesla’s absolute numbers left it with a 1.2 percent share of all new car registrations for October. Chinese competitors did record higher volumes, as BYD registered 5,173 vehicles, a 2 percent share, Leapmotor with 3,661 cars, which equates to 1.4 percent, and Xpeng had a 0.5 percent share.
Year-to-date through October, BYD edged ahead of Tesla with 47,961 registrations versus Tesla’s 47,742.
The October results follow a notably strong September for Tesla in Germany, when it registered 12,552 vehicles, an increase of roughly 269 percent year-over-year and one of its strongest monthly totals on record in the country. That month, the Model Y led all EVs and ranked among the top-selling vehicles of any powertrain.
The figures form part of a broader recovery in Tesla’s European registrations after an extended period of softer demand. While monthly volumes remain subject to typical quarter-end patterns and competitive pressure from both established European brands and rapidly expanding Chinese manufacturers, the year-to-date growth indicates improved traction in Europe’s largest car market.
Tesla’s Gigafactory Berlin-Brandenburg continues to supply the region, positioning the company to capture a share of the expanding German BEV market as overall EV adoptions looks to be accelerating.
