Tesla has offloaded Maxwell Technologies’ ultracapacitor business to UCAP Power, Inc., a developer of ultracapacitor-based power solutions. The announcement was posted in a press release, which noted that the deal included the purchase of Maxwell Technologies Korea, the company’s Korea-based ultracapacitor business, as well as other assets related to the Maxwell brand.
Gordon Schenk, UCAP Power CEO, was optimistic about the deal. “We’re thrilled to combine Maxwell Technologies Korea’s ultracapacitor manufacturing capabilities and one of the largest patent and product portfolios in the industry with the growing family of products developed by UCAP Power,” he said.
UCAP Power’s purchase of Maxwell’s ultracapacitor business comes amidst Tesla’s focus on dry electrode battery technology, another key product in Maxwell’s portfolio. After Tesla’s purchase of Maxwell Technologies in 2019, speculations suggested that the EV maker may be looking to integrate ultracapacitors in its vehicles. Tesla, however, opted to utilize Maxwell’s dry electrode tech instead, which was then used in the company’s 4680 cells.
In a recent post on Twitter, Elon Musk confirmed that Tesla’s offloading of Maxwell’s ultracapacitor business is quite ironic since he was, at one point, looking to do his Ph.D. at Stanford on high energy density capacitors for EVs. The Tesla CEO explained, however, that lithium-ion batteries today can already usher in a sustainable future, even without radical advances. Maxwell’s dry electrode technology is then a key part of the puzzle, especially with regards to lowering the cost of batteries.
“Ironic indeed, as I was at one point going to do my Ph.D. at Stanford on high energy density capacitors for use in electric vehicles. But lithium-ion has it covered. Even with no advances in lithium-ion technology, it’s possible to transition Earth to sustainable energy. Dry electrode is a key piece (one of many pieces) of the puzzle for lowering cost of lithium batteries. That said, it has required an *immense* amount of engineering to take Maxwell’s proof-of-concept to high-quality, volume production & we’re still not quite done,” Musk wrote.
This was not the first time that Elon Musk mentioned the challenge of ramping the production of Tesla’s custom 4680 battery cells, which are expected to be used in vehicles like the Cybertruck and the Semi. Considering that both the Cybertruck and the Semi are reportedly on track to start initial deliveries this year, there seems to be a pretty fair chance that Tesla’s 4680 cells, and the dry electrode tech that goes into them, are closing in on meaningful volume production.

Tesla Model Y on FSD saves couple after encountering King of edge cases
Experts have noted that if confirmed, this could be the world’s first recorded meteorite collision involving a Tesla.
A South Australian Tesla driver is thanking his Model Y’s Full Self-Driving system after a mysterious object, possibly a meteorite, slammed into his car’s windshield while it had FSD engaged.
The impact sent hot glass fragments flying through the cabin as the vehicle continued driving without human input through the darkness. Experts have noted that if confirmed, this could be the world’s first recorded meteorite collision involving a Tesla.
The Tesla owner was enjoying a quiet drive home when they hit the king of edge cases
Veterinarian Dr. Andrew Melville-Smith and his wife were traveling north on Augusta Highway on the night of October 19 when a sudden blast struck their newly delivered Model Y. At the time, it was clear, pitch black night, and Dr. Melville-Smith and his wife were just listening to a podcast while FSD was operating the vehicle, as noted in a Yahoo News report.
Suddenly, something hit the Tesla’s windshield. “Then there was, (what) I can only describe as a very, very violent explosion. The whole inside of the car was literally blasted with glass fragments. It was full of white smoke, and it smelled like the car was on fire,” Dr. Melville-Smith stated.
The vet stated that he and his wife were stunned for a good 10 seconds, and for a bit, he and his wife thought they had crashed. Images of the crash’s aftermath showed a massive crack on the Tesla’s windshield, which Dr. Melville-Smith noted was hot to the touch. The object that hit the Tesla’s windshield was so hot that part of the vehicle’s windshield was partly melted.
FSD kept driving despite the possible meteorite strike
Thankfully, the Tesla was operating with its FSD (Supervised) system engaged at the time. Thus, despite the vehicle being hit by what might be a literal meteorite, and despite Dr. Melville-Smith and his wife being stunned because of the impact, their Tesla just kept driving steadily.
“I thought we’d had an accident, but then I looked at the screen and went ‘Oh, we’re still driving. We were moving around, so it obviously thought we were paying attention, and it was happy to keep driving to Port Augusta. After we pulled over, we saw the big crater in the windscreen,” the vet said.
The South Australian Museum is now examining the case, with geologist Dr. Kieran Meaney stating the scorched glass and heat damage do suggest a potential meteorite strike. “The little detail that’s really selling it for me at the moment is that whatever it was that hit the windscreen seems to have been very hot,” Meaney explained. However, the object has yet to be recovered.

“Foundation:” Elon Musk wants to send a record of Grokipedia to space
The idea sounds outlandish, though it is also something that is in character for the CEO.
Elon Musk has announced one of his latest initiatives, and it is every bit as sci-fi as it is surprisingly grounded. In a post on X, Musk stated that Grokipedia, xAI’s new open-source encyclopedia, will be etched into stable oxide and launched into space.
The idea sounds outlandish, though it is also something that is in character for the CEO.
Preserving human knowledge among the stars
Musk posted his plan following the launch of Grokipedia’s V0.1’s iteration. The CEO congratulated the xAI team for the online encyclopedia’s launch, though he also stated that the goal for Grokipedia is to create an open-source collection of knowledge. This would then be distributed to the cosmos.
“Nice work by the xAI team on Grokipedia! The goal here is to create an open source, comprehensive collection of all knowledge. Then place copies of that etched in a stable oxide in orbit, the Moon, and Mars to preserve it for the future. Foundation,” Musk wrote in his post.
While seemingly outlandish, this is not the first time that a record of human knowledge of sorts was sent out to space. In 1977, the Voyager Golden Record was launched aboard NASA’s Voyager 1 and 2 spacecraft. The record contains sounds and images that ere aggregated to portray the diversity of the Earth’s culture. Of course, Musk’s plan with Grokipedia, is infinitely more ambitious.
Grokipedia and AI neutrality
Musk launched Grokipedia as an AI-driven alternative to Wikipedia, designed to eliminate the human biases that could affect conventional online knowledge platforms. The system is powered by xAI’s Grok, which scrape and summarize information from across the internet, offering balanced and nuanced coverage of topics ranging from science and technology to culture and politics.
Unlike Wikipedia’s human-edited format, Grokipedia would be able to evolve through machine learning, reading vastly more material than any editorial team could. Early testers, including Wikipedia co-founder Larry Sanger, praised its initial version as “very OK” and potentially more neutral than Wikipedia. Musk agreed, stating that even in its V0.1 form, Grokipedia is “already better than Wikipedia.”

Tesla Cybertrucks to save Las Vegas police thousands in fuel and maintenance
Sheriff Kevin McMahill unveiled the new vehicles on Monday, describing them as “the next evolution to keep our community safer than it’s ever been.”
The Las Vegas Metropolitan Police Department has officially unveiled its fleet of Tesla Cybertrucks as part of its push toward a more advanced, cost-efficient, and sustainable patrol system.
Sheriff Kevin McMahill unveiled the new vehicles on Monday, describing them as “the next evolution to keep our community safer than it’s ever been.” The trucks are expected to begin service across all area commands within two weeks.
High-tech patrol fleet
Each UP.FIT-modified Cybertruck has been customized with ladders, shields, and less-lethal equipment to support law enforcement operations. The vehicles will connect to a live drone response hub capable of facial recognition and gunshot detection, enabling drones to launch automatically when alerts trigger. The system streams real-time footage directly to responding officers, enhancing both speed and situational awareness during emergencies.
Officers have already completed training with the new fleet and offered feedback on its performance, according to Fox 5 Vegas. Sheriff McMahill noted that the trucks, along with robot dogs and SWAT vehicles, represent a coordinated effort to combine human expertise with emerging technologies. The Cybertruck rollout was made possible through a donation from the Horowitz family.
Cybertrucks’ major savings
The department’s ten UP.FIT patrol Cybertrucks are among the most American-made law enforcement vehicles available, featuring roughly twice the domestic parts content of comparable Ford and Chevrolet patrol trucks. Beyond their build quality, the electric fleet offers major cost benefits. Each Cybertruck is projected to save between $8,800 and $12,000 in annual fuel costs and roughly $3,540 in maintenance over a five-year service life.
With regenerative braking, factory ballistic-resistant doors, and no idling fuel burn, the Cybertruck platform provides higher uptime, lower total cost of ownership, and a quieter patrol experience, all while reducing the department’s carbon footprint. Sheriff McMahill confirmed each area command will receive one of the new patrol units.
