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.

The Starship V3 static fire everyone was waiting for just happened

SpaceX fired all 33 Raptor 3 engines on Starship V3 today clearing the path for Flight 12.

SpaceX Starship V3 from Starbase, Texas on April 14, 2026

SpaceX is that much closer to launching their next-gen Starship after completing today’s full duration static fire of all 33 Raptor 3 engines out of Starbase, Texas. This marks the most powerful rocket engine test ever conducted and a direct signal that Flight 12, the maiden voyage of Starship V3, is imminent. SpaceX confirmed the test on X, posting that the full duration firing was completed ahead of the vehicle’s next flight test.

The road to today started on March 16, when Booster 19 completed a shorter 10-engine static fire, also at the newly constructed Pad 2. That test ended early due to a ground systems issue but confirmed all installed Raptor 3 engines started cleanly. Booster 19 returned to the Mega Bay, received its remaining 23 engines for a full complement of 33, and rolled back out this week for the complete test campaign. Musk confirmed earlier this month that Flight 12 is now 4 to 6 weeks away.

Countdown: America is going back to the Moon and SpaceX holds the key to what comes after

The numbers behind today’s test are genuinely hard to put in context. Each Raptor 3 engine produces roughly 280 tons of thrust, and with all 33 firing simultaneously, this generates approximately 9,240 tons of combined thrust, more than any rocket in history. For context, that’s enough thrust to lift the entire Empire State Building, and then some. V3 stands 408 feet tall and can carry over 100 tons to low Earth orbit in a fully reusable configuration. The V2 generation topped out at around 35 tons.

Historically, a successful full-duration static fire is the last major ground milestone before launch. SpaceX has followed this pattern with every Starship iteration since the program began in 2023.  Musk has been direct about the ambition behind all of it. “I am highly confident that the V3 design will achieve full reusability,” he wrote on X earlier this year. Full reusability of both stages is the foundation of SpaceX’s plan to make regular flights to the Moon and Mars economically viable. Today’s test brings that goal one significant step closer.


Starship V3 delivers on two most critical promises of full reusability and in-orbit refueling. The reusability case is straightforward, and one we have seen with Falcon 9 wherein the rocket can fly again within a day rather than building a new one for every mission. It’s the only economic model that makes frequent lunar cargo runs viable. The in-orbit refueling piece is less obvious but equally essential. To reach the Moon with enough payload, Starship requires roughly ten dedicated tanker flights to fuel up a propellant depot in low Earth orbit before it can even begin its journey to the lunar surface. That capability has never been demonstrated at scale, and Flight 12 is the first step toward proving it works. As Teslarati reported, NASA’s Artemis II crew completed a historic lunar flyby earlier this month, the first humans to travel beyond low Earth orbit since 1972, but getting astronauts to actually land and eventually supply a permanent Moon base requires a cargo pipeline that only a fully reusable, refuelable Starship V3 can deliver at the volume and cost NASA’s plans demand.

Tesla Full Self-Driving shows stunning maneuver in Europe to silence skeptics

Tesla Full Self-Driving, fresh on the heels of its approval for operation on European roads for the first time, showed off a stunning maneuver that will certainly silence any skeptics on the continent.

Fresh off its approval in the Netherlands, Full Self-Driving is working toward a significant expansion into more parts of Europe.

In a striking demonstration of autonomous driving prowess, Tesla’s Full Self-Driving (FSD) system recently showcased its capabilities on the narrow rural roads of the Netherlands. Captured in two in-car videos, the system encountered scenarios that would challenge even the most experienced human drivers.

In the first clip, a wide tractor occupied more than half the lane on a tight two-way road. Rather than braking abruptly or forcing a collision risk, FSD smoothly edged the vehicle onto the adjacent bike path—using the extra space with precision—before seamlessly returning to the lane once clear.

The second clip was equally demanding: while overtaking a group of cyclists, an oncoming car approached at speed.

FSD maintained a safe, minimal buffer to the cyclists while timing the pass perfectly, avoiding any swerve or hesitation that could unsettle passengers or other road users.

This maneuver highlights FSD’s advanced spatial reasoning and predictive planning. On roads often under three meters wide, with no room for error, the system calculated available clearance in real time, incorporated shoulder and path geometry, and executed a controlled deviation without compromising safety.

It treated the bike path as a legitimate extension of navigable space, something many drivers might hesitate to do, while respecting Dutch road norms and cyclist priority.

Such feats align closely with a growing library of impressive FSD maneuvers documented on camera worldwide.

In urban Amsterdam, for instance, FSD has navigated the world’s densest cyclist environments, weaving through hundreds of unpredictable bike movements on canal-side streets with tram tracks and pedestrians.

One uncut drive showed it yielding smoothly at crossings, overtaking where needed, and even handling a near-perfect auto-park in a tight residential spot, demonstrating the same low-speed precision seen in the rural clips.

Teslas using FSD have tackled turbo roundabouts in the Netherlands, complex multi-lane circles notorious for geometry challenges, merging confidently while yielding to traffic. Similar clips depict smooth handling of construction zones, emergency vehicle pull-overs, and gated parking barriers, where the car stops precisely, waits for clearance, and proceeds without driver input.

Collectively, these examples illustrate FSD’s evolution toward handling the unpredictable.

The rural Netherlands maneuvers aren’t isolated. Instead, they reflect a pattern of spatial awareness, cyclist deference, and traffic anticipation seen from city streets to highways.

As FSD continues refining through real-world data, videos like this one are certainly building a compelling case for its readiness on Europe’s varied roads.

Tesla is utilizing its ‘Rave Cave’ for an awesome new safety feature that will arrive with the upcoming Spring Update for 2026.

Part of the massive interior overhaul of both the Model 3 “Highland” and Model Y “Juniper” was the addition of interior accent lighting to help bring out the mood of the vehicle, increase the customization of the interior, and to create a unique listening experience.

Tesla added a Sync Lights feature that will strobe the accent strips with the beat of the music.

It is one of the most unique and one of the coolest non-functional features of a Tesla, as it does not improve the driving of the vehicle, but makes it a cool and personal addition to the interior.

However, Tesla is going to take it one step further, as the Rave Cave lights will now be used for blind spot recognition. This feature will be added as the Spring 2026 Update starts to roll out.

Tesla writes:

“Accent lights now turn red when an object is in your blind spot and your turn signal is engaged, or when an approaching object is detected while parked.”

This neat new safety feature will now increase the likelihood of a driver, who is operating their Tesla manually, of seeing the blind spot warnings that are currently available on the A pillar and on the center touchscreen.

These new alerts will now warn drivers of cross traffic as they back out of a parking space with little to no visibility of what is coming. It is a great new addition that will only increase the safety of the vehicles, while also utilizing something that is already installed in these specific Model 3 and Model Y units.

The Model 3 and Model Y were the central focus of the Spring 2026 Update, especially considering the fact that the Model S and Model X are basically gone, with only a few hundred units left. Additionally, Tesla included new Immersive Sound and Car Visualization for the Model 3 and Model Y specifically in this new update.
