Tesla Model 3-based ventilator critiqued by ICU nurse: “Very good job…well done.”
An Anaesthetics and Intensive Care Unit (ICU) nurse recently broke down Tesla’s video of its in-house ventilator system that is made from Model 3 parts.
YouTuber Chris Vanderstock is a nurse by trade and holds over 20 years of experience in a medical setting. His resume includes years of administering patients with real-life medical conditions anesthesia before surgeries and providing them with air via the operation of a manual resuscitator. Vanderstock has plenty of experience with critical care ventilators and how they operate making him a prime candidate to give Tesla’s engineering team relevant feedback toward its newly designed machine.
Vanderstock was initially impressed with Tesla’s utilization of its vehicle parts to create an efficient ventilator. “I reckon a good two-thirds of this ventilator is from existing parts that Tesla already has,” the veteran nurse said. After listing the parts that will be included in the ventilator, like the Model 3’s display, Vanderstock gave his kudos to the Tesla team. Tesla’s goal was to use primarily parts that it knew for reliability purposes, as well as not take away any parts from the medical community who are already struggling with providing hospitals with ventilators, to begin with.
The mixing chamber that is responsible for combining several gases to create breathable air for a patient who is having trouble breathing is a critical part of a ventilator. Along with the mixing chamber, several pressure monitors, along with volume sensors that will provide the patient with the correct levels of oxygen, are included in the Tesla ventilator. Vanderstock noted that this is one of the most crucial parts of a ventilator, as too much air into the lungs can overinflate them, causing more damage than there was initially. Tesla nailed this, according to Vanderstock. “Kudos to these guys.”
Perhaps one of the most exciting portions of the Tesla-made ventilator is the use of two filters, one on the patient end where air is distributed to a patient’s lungs, and one on the machine end, where the virus will be displaced as the patient exhales. This double-filter feature is a notable part of ventilators from Medtronic, a company that Tesla has been in talks with since late March. Vanderstock says the ventilator’s machine-end filter is crucial to keeping healthcare workers safe, as a non-filtered machine end could lead to the virus being spread to those in the room.
The only concern Vanderstock had about the ventilator was how Tesla planned to warm and humidify the oxygen that will go to a patient’s lungs. “When you are thinking about how we breathe, our nose, the turbinates, the structures behind your mouth, going down your trachea into your lungs, are all being warmed…by your blood supply. As air travels down, it gets warmed on the way, and obviously, you’ve got the mucosal layers that’s sending in a bit of moisture as well,” he remarked.
One of Vanderstock’s favorite features is the inclusion of the Model 3 dash screen that will display information like pressure and oxygen concentration to medical professionals. “The innovative infotainment system could potentially help patients. Very good job at Tesla, well done,” he said.
All in all, Vanderstock is exceptionally impressed with Tesla’s ability to create a ventilator that has such an effective manner in a short amount of time. “Nonetheless, great first effort,” he said.
While the machine will still have to pass through Food and Drug Administration (FDA) regulations, he believes this process could be expedited as ventilators are needed on the front lines of hospitals in some of the United States’ most prominent cities.
CEO Elon Musk has stated that ventilators, whether they are purchased or manufactured by Tesla, will be available for free with worldwide shipping as long as the hospital requesting the machines is in immediate need of them. Musk has already made over 1,200 donations to Los Angeles and New York City hospitals as the COVID-19 pandemic is expected to reach its peak this week, according to U.S. Surgeon General Jerome Adams.

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.
