Tesla explores safer battery production with novel DCM recovery system patent

Published

on

In what appears to be yet another step towards its goal of operating the safest car factory in the industry, Tesla has been granted a patent that could pave the way for a safer process in battery production. Published today, the electric car maker’s recent patent describes a system to treat and recycle Dichloromethane (DCM), which is among the materials used in the production of electric car batteries.

DCM is utilized in a variety of industrial processes, particularly in chemical plastic welding, wherein softened plastic pieces or surfaces are welded together. The material is also used to soften plastic sheets for stretching or shaping, and as a solvent to remove unwanted compounds. In Tesla’s case, DCM is among the materials used in the forming of a separator base film for an electric car’s battery system. While DCM is invaluable in manufacturing, though, the material carries some health risks.

Dichloromethane is the least toxic among the simple chlorohydrocarbons, but its high volatility makes it an inhalation hazard nonetheless. Prolonged skin contact with DCM could also result in the material dissolving some of the skin’s fatty tissues, causing irritation or chemical burns. With these risks in mind, the manufacturing industry employs ways to recover DCM. Tesla notes that current systems for DCM treatment and recovery are capital intensive, particularly since the process involves expensive components such as activated carbon beds, condensers, steam boilers and distribution systems, density separation vessels, and waste water treatment systems.

Tesla describes conventional DCM treatment systems as follows:

“The DCM itself may then be removed through a heating and/or evaporation process with the exhaust collected. This exhaust containing DCM is then combined with the exhaust from other tools and systems used in the manufacturing process. The combined exhaust may then be fed to a recovery plant to recover DCM. In the recovery plant, the waste exhaust stream is typically treated with activated carbon. This scrubbing process requires high capital expenditure (many expensive components), high operating cost (extensive steam and cooling water consumption which accounts for >20% of total process cost), large footprint requirements, and large amounts of waste water that need to be processed. In order to address these cost and environmental-remediation issues, an improved process for the removal of DCM from exhaust streams is needed.”

Tesla’s take on DCM treatment and recovery utilizes a wet scrubber and a density separator vessel as key components of the system. The wet scrubber in Tesla’s patent has a scrubbing chamber, where water is utilized to scrub the waste exhaust stream containing the DCM. Tesla notes that the wet scrubber could adopt a variety of designs to remove DCM from the waste exhaust stream, including a venturi scrubber design, a condensation scrubber design, an impingement-plate scrubber design, or a packed bed tower design, among others.

Tesla’s use of a density separator vessel is described in the following section from the patent.

“The density separator vessel has an inlet to receive the liquid water and DCM mixture, an outlet to expel DCM, and an outlet to expel waste water. The DCM may be routed back to the industrial process for reuse and/or collected for later use. The waste water may be routed back to the wet scrubber, as shown along (the) waste water return loop. Waste water may also or alternately be routed to waste water treatment system for processing for subsequent treatment by (the) waste water treatment system.

“Typically, a large portion of the waste water is returned to the wet scrubber via (the) waste water return loop and a small portion of the waste water is treated by the waste water treatment system. Even though the waste water may contain small amounts of DCM, the waste water will still retain its ability to scrub the exhaust containing DCM. An advantage of the wet scrubber over the activated carbon beds is that all or most of the water used by the wet scrubber is the waste water from the density separator vessel, resulting in substantial savings of water and energy, and resultantly, substantial cost savings.”

Tesla states that compared to more traditional exhaust treatment systems, the DCM treatment and recovery model outlined in its patent effectively eliminates the use of steam and cooling, while also reducing the amount of throughput needed by a waste water system. With these efficiencies in mind, Tesla notes that it could reduce capital expenditures and operating costs “for the same amount of DCM processed processing.” The increased simplicity of the system and reduced airflow rates are expected to help the company get more savings in both capital expenditures and operating costs as well.

More than a way to optimize its operations, Tesla’s recent patent is also a notable way for the company to keep its battery production lines safer for its employees. Such a system would definitely be invaluable for the company, particularly as Tesla is now preparing the Model 3 for a global rollout. With the Model 3 ramp ever-expanding, and with high-volume vehicles like the Model Y and possibly the Tesla pickup truck in the pipeline, optimizations such as a better DCM treatment and recovery system are all but necessary.

Elon Musk

SpaceX’s newest Starmind will make earth data centers obsolete

Elon Musk confirmed Starmind as SpaceX’s AI satellite constellation name, targeting one million orbital compute nodes.

Published

Elon Musk confirmed that Starmind will be the official name of SpaceX’s planned AI satellite constellation, following a trademark filing by xAI that surfaced earlier this week. Starmind is what’s being described to the FCC as a constellation of up to one million AI satellites

It’s worth noting that SpaceX’s Starlink communication satellite and Starmind are built on the same orbital infrastructure concept but serve entirely different purposes. Starlink is a connectivity network, with satellites receiving and relaying data between points on Earth, and functioning as a high-speed internet backbone in space. The satellites themselves do not process or think, and move information from one place to another, the same function a fiber cable performs underground.

SpaceX just forced Verizon, AT&T and T-Mobile to team up for the first time in history

Starmind, on the other hand, is something completely different, and tather than moving data, its satellites would compute data through artificial intelligence and directly in orbit using onboard processors powered by large solar arrays. Where a Starlink satellite is essentially a very fast pipe, a Starmind satellite is a server. The practical implication is that Starmind would allow AI models to run inference, process queries, and generate outputs from space, then beam results down to users anywhere on Earth within milliseconds, and without the data ever needing to travel to a terrestrial data center.

Starship will be able to carry 30 to 50 AI1 satellites per launch, delivering the equivalent of dozens of server racks per flight, with no land acquisition, no power grid approval, and no cooling infrastructure required on the ground.

SpaceX is pursuing this new technology as terrestrial data centers are running into hard limits such as lack of physical space, community opposition, and power and water consumption at a scale that is increasingly difficult to permit. Space has unlimited solar power, natural vacuum cooling, and no zoning boards. Musk said in a June 8 video presentation that he expects space to become the lowest-cost location to deploy AI compute within two to three years. Two AI1 prototypes are scheduled to launch in early 2027, with volume production targeted for the end of that year at a new facility called Gigasat.

The real world applications Starmind enables extend well beyond powering Grok. A constellation of orbiting AI processors could run inference workloads for any paying customer, anywhere on Earth, with latency measured in milliseconds rather than the seconds associated with ground-based cloud routing across continents. Starmind, if it scales as described, would make SpaceX the landlord of AI compute the same way Starlink made it the landlord of satellite internet.

SpaceX makes $20 billion move to optimize its balance sheet

Published

SpaceX announced today that it commenced its first-ever public bond offering, marking a significant step in the newly public company’s capital markets strategy.

The company announced an offering of senior unsecured notes expected to raise at least $20 billion.

The move comes just a short time after SpaceX completed one of the largest initial public offerings in history. In mid-June, the company priced shares at $135 and raised more than $85 billion, propelling founder Elon Musk’s net worth past the trillion-dollar mark and giving the firm substantial liquidity.

According to the company’s SEC filing, the net proceeds from the notes will be used primarily to repay in full the outstanding borrowings under its existing bridge loan facility, cover related fees and expenses, and fund general corporate purposes. The offering is being conducted under Rule 144A, as well as Regulation S, targeting qualified institutional buyers and non-U.S. investors. Notes will be unsecured obligations ranking equally with other unsubordinated debt.

The $20 billion bridge loan was used to refinance approximately $17.5 billion in higher-cost “junk” debt tied to X and xAI. SpaceX had merged with xAI in February 2026 in an all-stock deal. The bridge facility, which matures in September 2027, had represented the bulk of SpaceX’s long-term debt.

In connection with the bond launch, SpaceX disclosed it held approximately $100.8 billion in cash and cash equivalents as of June 19. Investor calls began on the announcement date, with pricing and launch expected shortly thereafter. Rating agencies have assigned investment-grade ratings to the proposed bonds, reflecting confidence in SpaceX’s dominant position in commercial launches and the growth trajectory of its Starlink internet offering.

The debt raise also allows SpaceX to optimize its balance sheet by replacing short-term, higher-cost bridge financing with longer-date, lower-cost fixed-income securities. This provides greater financial flexibility to support capital-intensive initiatives, including the development of Starship, the expansion of the Starlink constellation, and the integration of AI capabilities following the xAI combination.

SpaceX shares (NASDAQ: SPCX) fell sharply on the news, dropping over 16 percent overall on the market on Monday. The stock had surged initially after debuting but pulled back amid profit-taking and broader market dynamics.

Overall, the bond offering underscores SpaceX’s transition to a mature public company with access to diverse funding sources. It positions the firm to pursue its long-term vision of multiplanetary expansion and AI infrastructure, while maintaining a disciplined approach to its capital structure in a high-growth but capital-heavy industry.

SpaceX is launching a secret spacecraft that could change how things are made in space

SpaceX’s secret disk-shaped Starfall capsule is targeting a market no reentry vehicle has cracked.

Published

on

By

SpaceX is targeting Tuesday, June 23 for the first flight of Starfall, a reentry capsule the company has developed almost entirely in private. The Falcon 9 launch window opens at 6:43 a.m. ET from Space Launch Complex 40 at Cape Canaveral Space Force Station, with a backup window available the same time on June 24. SpaceX has made no public announcement about the vehicle, only providing launch details. Everything known about it has come through FAA and FCC regulatory filings.

What makes Starfall different starts with its shape. Rather than the traditional cone used by Dragon and every other cargo return capsule in operation, Starfall is a flat disk that measures roughly  10.2 feet (3.1 meters) wide and just 2.5 feet (0.75 meters) tall, and weighing 4,630 pounds (2,100 kg) and capable of returning up to 2,200 pounds (1,000 kilograms) of payload from orbit. The disk geometry maximizes structural efficiency and payload volume relative to mass, and the heat shield mechanically jettisons just before splashdown, allowing recovery teams to retrieve both the capsule and the shield separately from the Pacific Ocean.

The difference with Starfall from existing competitors, such as Varda Space Industries, which has largely built the orbital manufacturing market and returns heavy payloads per flight is that Starfall’s specification is roughly 30 times more per mission, and is designed to be mass-produced and launched on either Falcon 9 or Starship. That combination of volume and launch access is something no standalone startup can replicate, and it puts SpaceX in direct competition with the companies that currently pay it to reach orbit.

The intended market is orbital manufacturing: pharmaceuticals, protein crystals, semiconductors, and advanced optical fiber that physically cannot be produced in the presence of gravity. FAA documents describe Starfall’s long-term purpose as building a “self-sustaining commercial in-space manufacturing market” and as a potential successor to the industrial capabilities of the International Space Station, which is set to retire in the late 2020s. Military rapid global cargo delivery is a parallel application under active discussion with the Pentagon.

The reason some industries seek manufacturing in space comes down to gravity. On Earth, gravity causes materials to settle, separate, and deform during production. In microgravity, those constraints disappear.

SpaceX’s already controls launch access, which means it currently functions as the landlord for every competitor in the orbital manufacturing return space. Starfall converts that landlord position into vertical ownership, and it would no longer just carry other companies’ capsules to orbit, but rather operate the capsule, own the return logistics, and capture the service revenue directly. Viewed alongside Starlink, Colossus, and the xAI merger, Starfall fits a consistent pattern: SpaceX identifying infrastructure layers that others depend on and moving to own them outright. Orbital manufacturing return is the next layer on that list.

If Tuesday’s reentry, parachute sequence, and recovery demonstration goes as planned, the second FAA-approved test flight follows. A successful pair of demos would position SpaceX to begin offering Starfall as a commercial service, likely first to pharmaceutical and materials science customers before scaling toward the military and broader manufacturing segments.
