A Tesla Model Y engineer, who suggested the heat pump’s inclusion, has left the company after ten years, his LinkedIn account said.
Joseph Mardall served as the Engineering Director for Tesla from April 2018 to January 2021 but has held several other roles with the electric automaker since joining the company in February 2011 as a Senior Thermal Engineer.
Arguably, Mardall’s largest accomplishment while working with Tesla was the groundbreaking Model Y heat pump, a system that was included in the all-electric crossover to handle cold temperatures and combat range loss due to winter climates. Mardall led three teams with 60 or more engineers responsible for developing new HVAC systems that would be compatible with electric vehicles. One solution was the heat pump, an idea that came from Mardall’s engineering teams and has been a big hit with proven success in the Model Y.
CEO Elon Musk even told Teslarati in March 2020 that the heat pump was “some of the best engineering I’ve seen in a while. Team did next-level work.”

Mardall is headed to Zipline as the Head of Engineering. He will be working with a team of engineers “to design and build the next generation of autonomous drones to provide every human on Earth with instant access to vital medical supplies,” his LinkedIn account says. He states that the highlights of his career at Tesla “included the ground breaking Model Y Heat Pump system and leading Tesla’s efforts to develop a ventilator.”
“After 10 wonderful years at Tesla, I’m super excited to start my next chapter as Head of Engineering at Zipline, working with a team of talented and committed engineers to provide every human on Earth with instant access to vital medical supplies. The next 5 years are going to change everything, and I can’t wait! We are hiring for all roles across engineering and I would love to hear from you – come fly with me!”
Interestingly, Mardall has some medical equipment development experience, even though his work before Tesla was at McLaren Racing. Mardall worked intensively on the Tesla ventilator developed by company engineers last year. As the COVID-19 pandemic raged on, Tesla was donating third-party ventilators to hospitals in need but decided to develop its own. The ventilator prototype that Tesla built was comprised completely of parts from the Model 3 sedan, including the dash screen to see measurements of patient vitals. Mardall was present in Tesla’s video of the ventilator, posted in April 2020.

It is unclear who Tesla will place in the Engineering Director Role currently. Mardall’s work at Tesla was innovative and crucial, and many Model Y (and Model 3 Refresh) owners will thank him every day for the duration of their ownership!

Musk bankers looking to trim xAI debt after SpaceX merger: report
xAI has built up $18 billion in debt over the past few years, with some of this being attributed to the purchase of social media platform Twitter (now X) and the creation of the AI development company. A new financing deal would help trim some of the financial burden that is currently present ahead of the plan to take SpaceX public sometime this year.
Elon Musk’s bankers are looking to trim the debt that xAI has taken on over the past few years, following the company’s merger with SpaceX, a new report from Bloomberg says.
xAI has built up $18 billion in debt over the past few years, with some of this being attributed to the purchase of social media platform Twitter (now X) and the creation of the AI development company. Bankers are trying to create some kind of financing plan that would trim “some of the heavy interest costs” that come with the debt.
The financing deal would help trim some of the financial burden that is currently present ahead of the plan to take SpaceX public sometime this year. Musk has essentially confirmed that SpaceX would be heading toward an IPO last month.
The report indicates that Morgan Stanley is expected to take the leading role in any financing plan, citing people familiar with the matter. Morgan Stanley, along with Goldman Sachs, Bank of America, and JPMorgan Chase & Co., are all expected to be in the lineup of banks leading SpaceX’s potential IPO.
Since Musk acquired X, he has also had what Bloomberg says is a “mixed track record with debt markets.” Since purchasing X a few years ago with a $12.5 billion financing package, X pays “tens of millions in interest payments every month.”
That debt is held by Bank of America, Barclays, Mitsubishi, UFJ Financial, BNP Paribas SA, Mizuho, and Société Générale SA.
X merged with xAI last March, which brought the valuation to $45 billion, including the debt.
SpaceX announced the merger with xAI earlier this month, a major move in Musk’s plan to alleviate Earth of necessary data centers and replace them with orbital options that will be lower cost:
“In the long term, space-based AI is obviously the only way to scale. To harness even a millionth of our Sun’s energy would require over a million times more energy than our civilization currently uses! The only logical solution, therefore, is to transport these resource-intensive efforts to a location with vast power and space. I mean, space is called “space” for a reason.”
The merger has many advantages, but one of the most crucial is that it positions the now-merged companies to fund broader goals, fueled by revenue from the Starlink expansion, potential IPO, and AI-driven applications that could accelerate the development of lunar bases.

Tesla pushes Full Self-Driving outright purchasing option back in one market
Tesla announced last month that it would eliminate the ability to purchase the Full Self-Driving software outright, instead opting for a subscription-only program, which will require users to pay monthly.
Tesla has pushed the opportunity to purchase the Full Self-Driving suite outright in one market: Australia.
The date remains February 14 in North America, but Tesla has pushed the date back to March 31, 2026, in Australia.

Tesla announced last month that it would eliminate the ability to purchase the Full Self-Driving software outright, instead opting for a subscription-only program, which will require users to pay monthly.
If you have already purchased the suite outright, you will not be required to subscribe once again, but once the outright purchase option is gone, drivers will be required to pay the monthly fee.
The reason for the adjustment is likely due to the short period of time the Full Self-Driving suite has been available in the country. In North America, it has been available for years.
Tesla hits major milestone with Full Self-Driving subscriptions
However, Tesla just launched it just last year in Australia.
Full Self-Driving is currently available in seven countries: the United States, Canada, China, Mexico, Australia, New Zealand, and South Korea.
The company has worked extensively for the past few years to launch the suite in Europe. It has not made it quite yet, but Tesla hopes to get it launched by the end of this year.
In North America, Tesla is only giving customers one more day to buy the suite outright before they will be committed to the subscription-based option for good.
The price is expected to go up as the capabilities improve, but there are no indications as to when Tesla will be doing that, nor what type of offering it plans to roll out for owners.

Starlink terminals smuggled into Iran amid protest crackdown: report
Roughly 6,000 units were delivered following January’s unrest.
The United States quietly moved thousands of Starlink terminals into Iran after authorities imposed internet shutdowns as part of its crackdown on protests, as per information shared by U.S. officials to The Wall Street Journal.
Roughly 6,000 units were delivered following January’s unrest, marking the first known instance of Washington directly supplying the satellite systems inside the country.
Iran’s government significantly restricted online access as demonstrations spread across the country earlier this year. In response, the U.S. purchased nearly 7,000 Starlink terminals in recent months, with most acquisitions occurring in January. Officials stated that funding was reallocated from other internet access initiatives to support the satellite deployment.
President Donald Trump was aware of the effort, though it remains unclear whether he personally authorized it. The White House has not issued a comment about the matter publicly.
Possession of a Starlink terminal is illegal under Iranian law and can result in significant prison time. Despite this, the WSJ estimated that tens of thousands of residents still rely on the satellite service to bypass state controls. Authorities have reportedly conducted inspections of private homes and rooftops to locate unauthorized equipment.
Earlier this year, Trump and Elon Musk discussed maintaining Starlink access for Iranians during the unrest. Tehran has repeatedly accused Washington of encouraging dissent, though U.S. officials have mostly denied the allegations.
The decision to prioritize Starlink sparked internal debate within U.S. agencies. Some officials argued that shifting resources away from Virtual Private Networks (VPNs) could weaken broader internet access efforts. VPNs had previously played a major role in keeping Iranians connected during earlier protest waves, though VPNs are not effective when the actual internet gets cut.
According to State Department figures, about 30 million Iranians used U.S.-funded VPN services during demonstrations in 2022. During a near-total blackout in June 2025, roughly one-fifth of users were still able to access limited connectivity through VPN tools.
Critics have argued that satellite access without VPN protection may expose users to geolocation risks. After funds were redirected to acquire Starlink equipment, support reportedly lapsed for two of five VPN providers operating in Iran.
A State Department official has stated that the U.S. continues to back multiple technologies, including VPNs alongside Starlink, to sustain people’s internet access amidst the government’s shutdowns.
