Redwood Materials, the battery recycling startup founded by former Tesla CTO JB Straubel, recently secured some funding from Amazon as part of the e-commerce giant’s efforts to reduce its emissions. Redwood is one of five companies that Amazon is investing in as part of its Climate Pledge Fund, which was announced last year and expected to cost about $2 billion. 

In a statement about the five companies that received funding, Amazon CEO Jeff Bezos stated that firms like Redwood are “channeling their entrepreneurial energy into helping Amazon and other companies reach net zero by 2040 and keep the planet safer for future generations.” Amazon, for its part, appears to be interested in Redwood’s recycling technology, which could allow materials like lithium, cobalt, and nickel to be extracted from old smartphones and other consumer devices. 

Redwood was founded by the former Tesla CTO in 2017 after seeing that the global shift to electric vehicles will likely cause unnecessary environmental damage from a surge in mining. Such a scenario would only happen, however, if there is no recycling system in place that would allow EV producers to reuse the materials that have already been used in their cars’ batteries. Speaking with the Financial Times, Straubel shared his vision for the transportation sector, which involves the mass adoption of EVs and a closed-loop battery recycling system. 

“(My vision is a) world where all of the transportation is done by electric vehicles and we have batteries powering a sustainable world. And all of those batteries are able to be recycled and remanufactured many, many times so that we can have a nearly closed-loop,” Straubel said.

This same concept stands just as true in the consumer electronics sector, according to the former Tesla CTO. Straubel remarked that while batteries are bound to degrade with repeated use, the underlying elements that comprise them remain sealed from the environment. This meant that the batteries’ materials, most of which are very valuable, could be broken down and repurposed once more. If this is accomplished, the former Tesla executive believes that mining would not be as necessary anymore. 

“There are a phenomenal amount of cell phones in the world that currently are being discarded as trash or thrown into a landfill. It’s a massive, untapped resource. If we can recover 98 or 99% of those materials and reuse them, we don’t need very much new material to keep that whole process running… Even though the battery is internally degraded, all of the same materials are still in there — all of the same atoms of lithium, nickel, and cobalt. You can still harness all of those same materials, but they need to be reprocessed and brought back to a state where they could be used again and built into a new battery,” Straubel remarked. 

The exact amount of funding that Redwood Materials has acquired from Amazon has not been disclosed by either company, through the former Tesla executive noted that there was a potential for “partnership on a number of different levels” between the recycling startup and the e-commerce giant. One of these levels may include aiding Amazon in building and developing an end-of-life process for consumer electronics that are sold through its e-commerce platform so that the devices and their components could be reused. 

Redwood Materials has remained mostly in stealth mode since its founding, though signs have emerged that the company may be part of Tesla’s efforts to develop its own battery recycling processes. One of these involves an existing partnership with Panasonic to reclaim the scrap that is generated from the battery cells currently produced at Tesla’s Gigafactory Nevada facility. Reports have indicated that Panasonic initially started a trial run with Redwood to reclaim more than 400 pounds of scrap from Giga Nevada, and the results were so successful that the Japanese firm raised its contract to 2 tons not long after.

SpaceX has previewed a major upgrade to Starlink Mobile, outlining next-generation satellites that aim to deliver significantly higher capacity and full 5G-level connectivity directly to mobile phones.

The update comes as Starlink rebrands its Direct-to-Cell service to Starlink Mobile, positioning the platform as a scalable satellite-to-mobile solution that’s integrated with global telecom partners.

SpaceX noted that the upcoming Starlink V2 satellites will deliver up to 100 times the data density of the current first-generation system. The company also noted that the new V2 satellites are designed to provide significantly higher throughput capability compared to its current iteration.

“The next generation of Starlink Mobile satellites – V2 – will deliver full cellular coverage to places never thought possible via the highest performing satellite-to-mobile network ever built.

“Driven by custom SpaceX-designed silicon and phased array antennas, the satellites will support thousands of spatial beams and higher bandwidth capability, enabling around 20x the throughput capability as compared to a first-generation satellite,” SpaceX wrote in its official Starlink Mobile page. 

Thanks to the higher bandwidth of Starlink Mobile, users should be able to stream, browse the internet, use high-speed apps, and enjoy voice services comparable to terrestrial cellular networks. 

In most environments, Starlink says the upgraded system will enable full 5G cellular connectivity with a user experience similar to existing ground-based networks.

The satellites function as “cell towers in space,” using advanced phased-array antennas and laser interlinks to integrate with terrestrial infrastructure in a roaming-like architecture.

“Starlink Mobile works with existing LTE phones wherever you can see the sky. The satellites have an antenna that acts like a cellphone tower in space, the most advanced phased array antennas in the world that connect seamlessly over lasers to any point in the globe, allowing network integration similar to a standard roaming partner,” SpaceX wrote.

Starlink Mobile currently operates with approximately 650 satellites in low-Earth orbit and is active across more than 32 countries, representing over 1.7 billion people through partnerships with mobile network operators. Starlink Mobile’s current partnerships span North America, Europe, Asia, Africa, and Oceania, allowing reciprocal access across participating nations.

Tesla’s Full Self-Driving (Supervised) system has now surpassed 8.4 billion cumulative miles.

The figure appears on Tesla’s official safety page, which tracks performance data for FSD (Supervised) and other safety technologies.

Tesla has long emphasized that large-scale real-world data is central to improving its neural network-based approach to autonomy. Each mile driven with FSD (Supervised) engaged contributes additional edge cases and scenario training for the system.

The milestone also brings Tesla closer to a benchmark previously outlined by CEO Elon Musk. Musk has stated that roughly 10 billion miles of training data may be needed to achieve safe unsupervised self-driving at scale, citing the “long tail” of rare but complex driving situations that must be learned through experience.

The growth curve of FSD Supervised’s cumulative miles over the past five years has been notable.

As noted in data shared by Tesla watcher Sawyer Merritt, annual FSD (Supervised) miles have increased from roughly 6 million in 2021 to 80 million in 2022, 670 million in 2023, 2.25 billion in 2024, and 4.25 billion in 2025. In just the first 50 days of 2026, Tesla owners logged another 1 billion miles.

At the current pace, the fleet is trending towards hitting about 10 billion FSD Supervised miles this year. The increase has been driven by Tesla’s growing vehicle fleet, periodic free trials, and expanding Robotaxi operations, among others.

With the fleet now past 8.4 billion cumulative miles, Tesla’s supervised system is approaching that threshold, even as regulatory approval for fully unsupervised deployment remains subject to further validation and oversight.

Elon Musk fired back at Wikipedia co-founder Jimmy Wales after the longtime online encyclopedia leader dismissed xAI’s new AI-powered alternative, Grokipedia, as a “ridiculous” idea that is bound to fail.

Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”

Wales made the comments while answering questions about Wikipedia’s neutrality. According to Wales, Wikipedia prides itself on neutrality. 

“One of our core values at Wikipedia is neutrality. A neutral point of view is non-negotiable. It’s in the community, unquestioned… The idea that we’ve become somehow ‘Wokepidea’ is just not true,” Wales said.

When asked about potential competition from Grokipedia, Wales downplayed the situation. “There is no competition. I don’t know if anyone uses Grokipedia. I think it is a ridiculous idea that will never work,” Wales wrote.

After Grokipedia went live, Larry Sanger, also a co-founder of Wikipedia, wrote on X that his initial impression of the AI-powered Wikipedia alternative was “very OK.”

“My initial impression, looking at my own article and poking around here and there, is that Grokipedia is very OK. The jury’s still out as to whether it’s actually better than Wikipedia. But at this point I would have to say ‘maybe!’” Sanger stated.

Musk responded to Sanger’s assessment by saying it was “accurate.” In a separate post, he added that even in its V0.1 form, Grokipedia was already better than Wikipedia.

During a past appearance on the Tucker Carlson Show, Sanger argued that Wikipedia has drifted from its original vision, citing concerns about how its “Reliable sources/Perennial sources” framework categorizes publications by perceived credibility. As per Sanger, Wikipedia’s “Reliable sources/Perennial sources” list leans heavily left, with conservative publications getting effectively blacklisted in favor of their more liberal counterparts.

As of writing, Grokipedia has reportedly surpassed 80% of English Wikipedia’s article count.
