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.

Tesla Cybertruck’s three configurations are all the same on the outside from an appearance perspective, but they differ slightly in price, range, performance, and other features. After yesterday’s price adjustment, Tesla’s Base All-Wheel-Drive Cybertruck is now priced at $74,990, a far cry from the $59,990 it started at several months ago.
At $60,000, the Cybertruck All-Wheel-Drive is a steal: no pickup, electric or gas-powered, comes close in terms of overall driving capability thanks to Steer-by-Wire; no truck is more fun to drive at that price, and add in Full Self-Driving for $99 per month, and you truly have the best possible pickup on the market, at least if you’re planning to use it for driving.
I unfortunately didn’t have the equipment to test towing and payload and how it impacts the truck.
But at $75,000, is it still worth it? Obviously, the question gets to be more difficult because of the $15,000 difference. But there’s still an argument.
I spent the last week with this awesome truck, and when I took it back, I was sad because it truly is the best Tesla in the lineup. I formerly said the Model S was my favorite Tesla, but after a week with Cybertruck, I can easily say it would be my choice over the now-defunct all-electric sedan.
What makes it so great? Well, a lot of things, and there are some things that I’d like to see change. However, this is a truck that truly has a serious argument for those who are thinking of trying something completely different.
Exterior and Interior
This build comes with 18″ Molten Wheels as the standard offering, but 20″ Core Wheels with 35″ tires are also available. The standard wheel option on this affordable model is not my favorite, but it can be easily swapped for something more attractive.
Overall, this particular build did have some panel gap issues that were especially noticeable between the hood and both front quarter panels. This is obviously not an “across the board” issue, as the Cyberbeast I took home for comparative reasons was significantly better overall.

The interior is different, with its textile material instead of the vegan leather. Personally, I missed the leather due to the ventilated seats, but I prefer the textile as I personally felt like they were more comfortable. This is something I’d definitely consider if I were between the three trim levels and money was not really an issue.
After 610 miles on Monday in this thing, I did not feel any different than I did when I left my house that morning. It feels like a living room on wheels; after a long drive, you truly do not feel as if you’ve been in a car all day long.
My biggest interior complaints were that I’d like at least two USB-C ports in the front; you are confined to just one, and it’s hidden in the center console. The rear row has two ports. Additionally, the windshield is super difficult to clean, so if you end up buying one of these, save your back and get something that extends.
Driving Performance and Comfort
One of the most surprising things about Cybertruck is the fact that it is perhaps the smoothest ride of any Tesla available. Most believe it might be rough, stiff, and rugged like most trucks, maybe not as forgiving on the back and bottom as you sit in it for an extended period of time.
I’m here to tell you, you won’t regret sitting in a Cybertruck for a long drive.
I put as many people who dislike EVs, don’t like Cybertrucks, or use trucks for work, and judge the Cybertruck in this thing in the past week. Every single person who got in this truck loved it: they loved the speed, the handling, FSD, the space, the capability, and the feel.
As previously noted, even after hundreds of miles and 14 hours spent driving around Pennsylvania, I didn’t feel tired, exhausted, or in any hurry to come home. I would have driven another 300 miles without question.
Final Thoughts
If I had my choice of the three Cybertruck trims, I think I’d take the All-Wheel-Drive for a few reasons. Initially, the price is more attractive, it is not that stripped of features, and it has everything I need.
Is it worth it at $75,000? I believe it is. I’ve driven trucks that are at a higher price point and consider this to be a better product from a driving and experience perspective. However, other pickups on the market have more towing capacity, payload capacity, and range. They do not have FSD or steer-by-wire, the two things that truly make the Cybertruck in a league of its own.
I can’t think of a time in recent memory that I’ve been this excited to drive a vehicle each day, and I literally look for excuses to drive my Model Y on a daily basis. This Cybertruck just blows the Model Y out of the water in every possible way, at least in my opinion. With the size, performance, and driving experience, there is no better Tesla out there.

County vote hands Elon Musk’s Vegas tunnel network a huge new target
Clark County approved 19 more Vegas Loop stations, pushing Boring Company’s entitled total to 123.
The Boring Company just got permission to nearly double how far Vegas Loop can reach. Clark County commissioners approved 19 additional stations for the underground transit system, bringing the total entitled to 123, the company said in a post on X thanking the county for the vote. Elon Musk’s tunneling company also flagged the direction it sees the project heading long term. “Because Loop is point-to-point with no intermediate stops, in the limit, one could have a Loop station in every driveway,” the company wrote.
That framing captures how far the ambitions have moved. The Vegas Loop opened its first stretch of tunnel in 2021 and has grown its footprint through a string of county approvals since. In 2023, commissioners signed off on 18 additional stations, part of a plan that later doubled the system’s target to 69 stations across 65 miles. By the end of that year the company was describing a build out closer to 93 planned stations. Last year the long term design called for 104 stations across 68 miles of tunnel. The new approval pushes that number to 123, another jump in a project that keeps outgrowing its own blueprints.
The Boring Company gets approval for more stations in Las Vegas
Station count on paper is still well ahead of what riders can actually use. As Teslarati reported earlier this month, the network has about 11 open stations and has carried more than 4 million passengers since it began running, with newer stops at Fontainebleau and Sahara among the latest additions to the Strip corridor. A tunnel connection to Harry Reid International Airport remains under construction and has already slipped past its original first quarter target. The company is also racing to finish a Westgate to Paradise Road segment that Las Vegas Convention and Visitors Authority CEO Steve Hill has said it hopes to have running in time for November’s Formula 1 race.
The gap between entitled stations and operating ones is where the real story sits. Regulatory approval gives Boring Company the legal runway to keep tunneling toward new resorts, residential pockets and eventually the airport, but building each connection still comes down to boring machines, fire safety sign offs and construction timelines that have slipped before. The company’s Prufrock series machines set an internal record in March with a 2.28 mile tunnel near Westgate, evidence that construction has been picking up even as the list of approved destinations grows faster than the tunnels themselves.
Musk’s driveway comment reads as aspirational rather than a near term plan, but it fits how Boring Company has talked about Vegas Loop from the start: treat every approval as a floor, not a ceiling, and keep pushing county officials for room to dig.
SpaceX announced today that it would expand its launch capabilities into a new U.S. state: Louisiana.
Today, SpaceX, in conjunction with the Louisiana Economic Development Office, said that it will establish a new launch facility, which it will call Starbase, Louisiana. It will be located near Vermilion Parish, supporting thousands of launches each year, at least eventually.
CEO Elon Musk commented by stating, “Starbase Louisiana will ultimately have over a dozen launch towers, enabling more than 30 Starship flights per day and making it the biggest launch site on Earth!”

The expansion is SpaceX’s latest move to push its launch cadence to be more frequent than ever. SpaceX said that Starbase, Louisiana, will be built to “support thousands of Starship flights a year,” with the first coming in 2029.
SpaceX announced the new facility in partnership with the Louisiana Economic Development Office as it will bring a major influx of jobs and investments into the area. Currently, it will produce more than 3,000 new jobs in Louisiana, and SpaceX plans to invest at least $100 billion into the entire facility, ensuring that many jobs are created as a result.
Environmental Responsibility
SpaceX acknowledges the impact launches could have on marshlands, local wildlife, and water sources. Here’s how the company plans to help with the issues in Vermilion Parish:
- Restoring the Shoreline: “In Vermilion Parish, the shoreline is eroding between 3.3 and 23 feet per year. We’re partnering with state and federal agencies to expand Louisiana’s Coastal Master Plan and Coastal Wetlands Planning, Protection and Restoration Act projects, including Gulf shoreline protection breakwaters designed to reduce wave energy and slow loss along the Gulf edge.”
- Rebuilding the Marshlands: “In working with the state, we’re planning thousands of acres of marsh creation using beneficial-use placement of dredged material and offshore sediment sources. Restoration will also include interior marsh bank stabilization and rebuilding marsh in remnant canals. These projects can reconnect fragmented wetlands, restore natural buffers against storms, and return habitat that has been lost to erosion and historic canalization.”
- Preserving Coastal Wildlife: “Pecan Island and nearby wetlands are high-value habitat for migratory waterfowl, shorebirds, wading birds, and other coastal wildlife. SpaceX is not developing the full footprint of the land and will preserve wetlands and wildlife habitat. At existing launch sites, waterfowl and other birds continue to use nearby habitat during operations. Working with wildlife agencies, landowners, and conservation groups, SpaceX will support monitoring and management so this habitat stays productive and hunting, fishing, birding, and other recreational activities that are part of this coast’s culture can continue.”
SpaceX shares rose about 2.5 percent on the news.
