Medtronic opens up about Elon Musk and SpaceX’s role in fight against COVID-19
Earlier this year, Elon Musk announced on Twitter that SpaceX would be working with medical device firm Medtronic to help the company produce its most advanced ventilators, which are pivotal in the battle against the pandemic. Details about the two companies’ collaboration have been quite slim since then, with Musk simply noting that SpaceX was producing valves for Medtronic.
In a recent post, Medtronic opted to share some key insights about its work with Elon Musk and his private space enterprise. The medical device maker’s story highlighted the value of Musk’s Silicon Valley-style approach to his companies, which emphasizes quick innovation that’s directed towards the development of real-world, practical solutions in the shortest time possible.
Medtronic’s Puritan Bennett 980 Ventilator Series is the company’s most advanced ventilator. It allows patients to breathe naturally through a series of innovative breath delivery technologies. It’s also fitted with a unique ventilator assistance feature that allows the machine to continue delivering ventilatory support even in the event of certain system failures. The flagship machine is built in Medtronic’s facility in Galway, Ireland, and it has become a staple in numerous hospitals.
In a typical year, Medtronic’s Galway plant could produce about 7,500 valves for its flagship ventilator. But with COVID-19 spreading across the globe, the need for ventilators increased rapidly and significantly. Medtronic promptly increased the production of its ventilators, and by mid-March, the Galway plant had raised its output by 40%. But it was not enough. Building ventilators is a complex process, after all, and the machines require advanced components that are difficult to manufacture.
One of these components is a proportional solenoid (PSOL) valve, a highly complex piece of machinery that controls the flow of air and oxygen inside the machine. The PSOL valve consists of over 50 parts, and each must be manufactured with surgical precision, with some components having tolerances as thin as a strand of hair. Medtronic’s most advanced ventilator used three of these PSOL valves per unit, and as noted by Medtronic Engineer Matt Phillips, the medical device firm was pretty much at a loss about how it could meet the increasing demand for its products.
And then Elon Musk called, and he came with a unique, interesting proposal.
Musk’s private space firm, SpaceX, which made its mark in the industry with its reusable rockets and its Crew Dragon spacecraft, offered to make PSOL valves for Medtronic. SpaceX proved to be the perfect partner for the medical device maker, as it already had a division that designs and manufactures valves for its rockets. The private space enterprise’s engineers were top-notch, and they had the technical expertise to stand up to the challenge. And with that, the two companies’ collaboration began.
In a display of its quick, Silicon Valley-style approach to problem-solving, SpaceX did not waste any time. COVID-19 was not letting up, and neither was Elon Musk’s private space enterprise. SpaceX promptly converted part of its rocket factory in Hawthorne, California to produce PSOL valves with the help of Medtronic employees. To maximize mobility and speed, the team even built a PSOL valve manufacturing line on carts. Ultimately, the SpaceX and Medtronic team achieved in months what might have otherwise taken years.
“They literally turned a rocket production area into a ventilator valve manufacturing facility almost overnight,” Phillips said.
As noted by the Medtronics engineer, SpaceX did not scrimp on its talent, with some of the engineers who worked on the Crew Dragon capsule working on the Medtronic project. Quality control was extremely high, with the valves produced at the SpaceX site undergoing rigorous testing before being shipped to Galway.
“We had their best technicians. We had their best engineers. Some of the people working on this project are the very people who just launched the first private commercial crew to the International Space Station. They brought the same kind of energy to this project that they brought to putting astronauts into space,” Phillips noted.
“When it comes down to it, these ventilators are going to save lives,” Phillips said. “So every component has to be perfect. There is no room for error, which is why we put these valves through such an intensive testing protocol,” the Medtronic engineer added.
Thanks in no small part to the quick initiative of the SpaceX team, the medical equipment company now has the capability to produce 9,000 PSOL valves for Medtronic’s flagship ventilator over the next 8 to 10 weeks. That’s about the same amount of valves that Medtronic’s Galway plant produced in 2019. The Galway facility, for its part, could now operate at five times the volume of its pre-pandemic operations.
“I have never seen anything like this in my life… This project certainly changed the way I look at production, partnership, and innovation. I know that, with the right focus and the right energy, we can take what we learned from this project and apply it to other challenges that come our way,” Phillips remarked.

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.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
