JB Straubel’s Redwood launches energy business focused on second-life EV batteries
Redwood stated that many EV battery packs retain more than 50% of their capacity after being retired from vehicles.

Redwood Materials, the battery recycling firm founded by Tesla co-founder JB Straubel, has launched a new venture called Redwood Energy. The business aims to repurpose used electric vehicle batteries into large-scale, low-cost energy storage systems.
In a post on X, Redwood revealed that it has already deployed a 12 MW, 63 MWh microgrid powered entirely by second-life EV batteries. The system is currently powering a modular data center for Crusoe AI, and it already operates at a lower cost than conventional solutions.
Repurposed batteries for scalable storage
Redwood Energy is designed to bridge the gap between battery recovery and recycling by extracting value from discarded EV packs that still hold usable charge. In a blog post, Redwood stated that many EV battery packs retain more than 50% of their capacity after being retired from vehicles. That remaining energy is well suited for stationary storage applications even without recycling.
The process begins with Redwood’s collection and diagnostics system, which identifies battery packs that are still suitable for reuse. Those packs are then integrated into modular energy systems that can store energy from solar, wind, or the grid. Once the batteries reach true end-of-life, they are recycled through Redwood’s closed-loop system to recover critical minerals.
Meeting the demands of an AI-driven grid
Redwood estimates that more than 100,000 EVs will be retired this year in the United States, with millions more currently on the road. These vehicles represent hundreds of gigawatt-hours of storage potential. These resources are coming in at the right time, as electricity demand is rising rapidly amid the rise of artificial intelligence, which tends to be power-hungry.
Redwood Energy already has more than 1 GWh of second-life batteries in its deployment pipeline. That figure is expected to grow to 5 GWh in the coming year. Larger 100 MW projects are also in development.

Tesla appears to have teased a long-awaited Model Y trim for a Friday launch
The company posted it with its Europe & Middle East account, and it appears to be a Model Y Performance, which has been spotted testing at the famed Nurburgring in Germany.

Tesla appears to have teased a long-awaited Model Y trim for a launch on Friday.

The Model Y Performance became a big-time hit after it packed the family-style interior with lightning-fast acceleration, speed, and handling.
As Tesla transitioned the Model Y into the updated “Juniper” design, the company took its time to create an even better vehicle with the new Performance configuration.
It has surely taken its time, but the vehicle appears to have undergone some exterior changes to enhance aerodynamics, handling, and overall performance.
We recently went into what was different about the test units spotted at Nurburgring in an article, but we’ll also list them here:
- New 21″ wheels
- All black headliner, a big change that was included in the Model Y L, the first time a Model Y has had that option
- Updated brakes
- Bucket seats that appear to be similar to the new Model Y L in China
- New Carbon Fiber Spoiler
- Performance Badging
- Changes to both the front and rear bumper
- Suspension with Adaptive Dampers
Tesla Model Y Performance zips around Nurburgring with new features
It does not seem like there’s much else it could be, but it is important to note that Tesla has been developing a handful of affordable models. There is a possibility that Tesla could launch one of these on Friday, but it seems unlikely.
The affordable models will likely be coming to the United States or China before they would in Europe.
They would be developed at Gigafactory Texas or Gigafactory Shanghai. The company stated in its Q2 Earnings Shareholder Deck that it had continued to expand its vehicle offerings and successfully manufactured the first builds of a more affordable model in June.
Volume production is planned for the second half of 2025.

SpaceX Starship Flight 10 was so successful, it’s breaking the anti-Musk narrative
That’s all the proof one could need about the undeniable success of Starship Flight 10.

Starship Flight 10 was a huge success for SpaceX. When both the Super Heavy booster and the Starship Upper Stage successfully landed on their designated splashdown zones, the space community was celebrating.
The largest and most powerful rocket in the world had successfully completed its tenth test flight. And this time around, there were no rapid unscheduled disassemblies during the mission.
As per SpaceX in a statement following Flight 10, “every major objective was met, providing critical data to inform designs of the next generation Starship and Super Heavy.” The private space enterprise also stated that Flight 10 provided valuable data by stressing the limits of Starship’s capabilities.
With all of Flight 10’s mission objectives met, one would think that it would be pretty easy to cover the story of Starship’s successful tenth test flight. But that’s where one would be wrong, because Elon Musk companies, whether it be Tesla or SpaceX or xAI, tend to attract negative slant from mainstream media outlets.
This was in full force with Starship Flight 10’s coverage. Take the BBC’s Facebook post about the fight test, which read “Elon Musk’s giant rocket, earmarked for use in a 2027 mission to the Moon, has had multiple catastrophic failures in previous launches.” CNN was more direct with its slant, writing “SpaceX’s troubled Starship prototype pulls off successful flight after months of explosive mishaps” on its headline.
While some media outlets evidently adopted a negative slant towards Starship’s Flight 10 results, several other media sources actually published surprisingly positive articles about the successful test flight. The most notable of which is arguably the New York Times, which featured a headline that read “SpaceX’s Giant Mars Rocket Completes Nearly Flawless Test Flight.” Fox News also ran with a notably positive headline that read “SpaceX succeeds at third Starship test flight attempt after multiple scrubs.”
Having covered Elon Musk-related companies for the better part of a decade now, I have learned that mainstream coverage of any of his companies tends to be sprinkled with varying degrees of negative slant. The reasons behind this may never be fully explained, but it is just the way things are. This is why, when milestones such as Starship’s Flight 10 actually happen and mainstream media coverage becomes somewhat objective, I can’t help but be amazed.
After all, it takes one heck of a company led by one heck of a leader to force objectivity on an entity that has proven subjective over the years. And that, if any, is all the proof one could need about the undeniable success of Starship Flight 10.

Tesla’s Elon Musk takes another shot at Waymo’s capabilities stemming from LiDAR
“LiDAR also does not work well in snow, rain or dust due to reflection scatter. That’s why Waymos stop working in any heavy precipitation.”

Tesla CEO Elon Musk has frequently expressed his opinions on LiDAR in the past, but in recent days, the EV maker’s frontman has continued to discuss the weaknesses in the technology and why his company has relied on cameras.
He also mentioned the suite’s limits on Waymo’s capabilities.
Tesla completely abandoned using radar alongside its camera suite a few years ago, something it referred to as “Tesla Vision” at the time. For its vehicles, it has only used cameras since this transition, and Musk has never once shied away from this strategy.
Earlier this week, he discussed the reliance of LiDAR and radar by other companies:
“Lidar and radar reduce safety due to sensor contention. If lidars/radars disagree with cameras, which one wins?
This sensor ambiguity causes increased, not decreased, risk. That’s why Waymos can’t drive on highways.
We turned off radars in Teslas to increase safety. Cameras ftw.”
Elon Musk argues lidar and radar make self driving cars more dangerous
He continued with this narrative again and mentioned Waymo specifically on a second occasion.
Musk’s focus this time was on Waymo vehicles and their capabilities in adverse weather, specifically snow, rain, or even dust storms, and how LiDAR struggles to navigate in these conditions.
He said:
“LiDAR also does not work well in snow, rain or dust due to reflection scatter. That’s why Waymos stop working in any heavy precipitation. As I have said many times, there is a role for LiDAR in some circumstances and I personally oversaw the development of LiDAR for the SpaceX Dragon docking with Space Station. I am well aware of its strengths and weaknesses.”

Tesla’s approach is significantly different than most companies. Waymo, Motional, Aurora, and Zoox all use LiDAR for their self-driving programs, while Tesla continues to rely on its camera-only approach.
Musk even said that Model S and Model X utilized a Tesla-developed high-resolution radar, but it could not “compare to passive optical (cameras), so we turned it off.”
Tesla developed high resolution radar and the hardware is actually present in Model S & X, but it just can’t compare to passive optical (cameras), so we turned it off.
As a side note, any military systems that rely on radar “stealth” technology are toast in a modern conflict,…
