A clean-energy car shouldn’t leave a polluting battery problem behind. Tesla’s goal is for no battery to ever end up in landfill. Across its U.S. operations, more than 90% of key materials like nickel and cobalt are already being recovered through recycling. Meaning less battery waste, less risk of... show more

Tesla opened the world’s first public Megacharger for Semi trucks. Six stalls in Bloomington, California, delivering up to 1.2 megawatts each. That's freight-level charging for trucks that need to move loads, not sit around waiting. Tesla Semi trucks need places to charge fast, get back on the road, and keep freight moving without turning every route into a battery-planning exercise. This is how the Semi starts getting its own infrastructure. Tesla TeslaCharging / Writer: Annette, Designer: Janné

A 45-minute commute sounds a lot less annoying when you can literally sleep through it. Cybercab’s seats recline surprisingly far, and with no steering wheel or pedals, there’s nothing inside pretending someone still needs to drive. You get in, stretch out and let the car deal with the road. That’s the part of autonomy people will probably appreciate very quickly. Traffic can be Tesla’s problem now.

Cybercab can change the whole emissions equation. Tesla projects it could nearly halve emissions per mile compared to Model 3 and Model Y. The reason? It actually works for a living. Most personal cars sit parked around 95% of the time. Cybercab does the opposite. Pick up. Drop off. Repeat. One car doing the work of several. Fewer cars needed. More people moved. Less waste per mile. That is how autonomy starts to look very useful. Tesla / Writer: Annette, Designer: Janné

Cybercab was never meant to be a regular car. It was engineered from the ground up as a dedicated robotaxi. Built for autonomy from day one. No driver layout. It's designed around uptime, passenger comfort, and cost per mile. Fewer parts. Less complexity. More time moving people. That's what purpose-built for autonomy actually means.

Getting someone to buy a car once is nice. Getting them to come back for another one is the real test. Tesla just ranked #1 in U.S. automotive brand loyalty for May, ahead of Ferrari, Toyota, Subaru and Honda. And it makes sense. FSD keeps improving, new features arrive regularly through software updates, and the performance you bought doesn’t just sit frozen in time. Tesla owners clearly don’t feel much need to shop around anymore. Tesla Whole Mars Catalog / Writer: Annette, Grok Imagine Designer: Janné

She claims she collects “a gallon a gas a day” using this solar panel she folds on top of her Tesla. 1) using proper energy conversions a Tesla Model 3 has the equivalent to less than a 3 gallon tank of gas. There is no way she is charging a 1/3 of her battery. 2)Maybe she is stating that the Model 3 gets the equivalent in range to what an equivalent gas powered vehicle would get in range per one gallon of gas? Either way, that solar panel is not adding that much range. Thoughts?

Tesla and SpaceX are about to need chips faster than the world can produce. The answer? Terafab. A chip factory in Texas so huge it will dwarf landmarks like the Pentagon and Apple Park, with a goal of producing more than 1 terawatt of compute every year. The point is to stop future Tesla and SpaceX growth from being limited by whoever can supply them. Elon says Terafab will eventually be worth more than any other building on Earth.

You probably need a bigger showroom door when nearly a full year of sales gets beaten in six months. Tesla just opened its new western Japan flagship at GranFront Osaka, right next to one of the country’s busiest retail and transit hubs. After selling roughly 10,600 cars in Japan in 2025, Tesla reached about 12,000 in just the first half of 2026. More visibility, easier test drives and a much bigger physical presence exactly when Japanese demand is picking up. That test-drive queue is going to get interesting.

There’s a special kind of pain when the math is hard, and the AI is also annoying. Grok 4.5 is a solid workhorse here. For vibe math in Programming Language Theory, it’s keeping up with Sol 5.6 and feels way more fun to work with. Some models want to write a whole museum of documents. Some keep poking you to “Continue” like a needy browser tab. Grok just gets into the math and keeps the session moving. Very useful when the problem is already hard enough without the AI becoming another assignment. Grok xAI / Writer: Annette, Grok Imagine Designer: Janné

This is why Tesla makes the safest vehicles in the world: • All Tesla models have received five-star safety ratings from the National Highway Traffic Safety Administration. • Built from the ground up with an all-electric architecture, resulting in low rollover risk and reduced occupant injury probability. • Uses anonymous/aggregated real-world data from millions of miles driven to enhance safety via over-the-air updates and inform future vehicle designs. • Battery packs designed to isolate and vent heat away from the cabin; historically (2012–2020 U.S. data), Tesla vehicles ~10x less likely to experience fire per mile than average gas vehicles. • Before a crash occurs, Tesla uses the front cameras to observe the scenario and prepare the seat belt system to react faster and with adequate force and timing when impact occurs, reducing the amount of slack in each seat belt. • Tesla’s advanced airbags are tuned to deploy according to crash type and different-sized occupants. This includes active venting that changes the amount of pressure within the inflated cushion by releasing gas according to the expected crash severity. • When a serious collision is detected, the hazard lights will turn on to increase your visibility and doors will automatically unlock for emergency access. At the same time, your Tesla will automatically contact emergency services to get help to you as quickly as possible. • Tesla vehicle structures are designed to cushion and protect the battery in the event of an accident. Onboard systems will automatically disconnect the high-voltage battery upon impact. If a battery fire does occur, the battery pack is designed to spread heat away from the cabin to protect occupants.

Hello Tata Motors I purchased a Tata Nexon EV (30 kWh battery pack) on 10 February 2024 for around ₹18 Lakhs. Tata claimed a range of 325 KM, but throughout my ownership I NEVER received more than 175 KM on a full charge. Now the condition has become even worse. My battery drains so fast that I can barely drive 90 KM per charge. After reporting this issue, even the service center admitted there is a battery problem. At the time of purchase, Tata Motors clearly promised an 8-year / 160,000 KM battery warranty and assured us that defective batteries would be replaced with NEW ones. But now, when the issue has actually occurred, they are trying to replace my battery with a REFURBISHED (second-hand) battery instead of a new one. I raised this issue in February 2026. It has been months, and despite continuous follow-ups, there is still no battery replacement and no proper response from Tata Motors. What is more shocking is that Tata keeps blaming driving habits for the poor range. But according to THEIR OWN meter, my average consumption over the last 6434 KM is 91 Wh/KM, which technically should deliver around 329 KM range. Yet in reality, I never received anything close to that. To make things worse, the car makes frightening noises while charging. Honestly, it feels unsafe and scary, as if something could go seriously wrong at any moment. And when I asked Tata about exchanging this problematic vehicle, they offered only ₹5 Lakhs for a well-maintained 1.5-year-old car purchased for ₹18 Lakhs. Is this a joke? My demands are simple: 1. Provide a BRAND NEW battery replacement instead of a refurbished battery. 2. Offer a fair replacement/exchange value for the vehicle. This has been the worst ownership experience of my life. Extremely disappointed with Tata Motors and their after-sales service. TATA.ev Nitin Gadkari Department of Transport Tata Motors_Cars

When Cybercab becomes available, people are going to do the mental math very quickly. Around $30K for a car that can drive itself, charge wirelessly, cost very little per mile, and skip most of the normal car-owner headaches. Then it gets more interesting. Sleep on the way. Work on the way. Send it on errands. Let it pick someone up. Let it earn when you are not using it. For elderly people, disabled passengers, busy families, and anyone tired of parking, Cybercab starts making a ridiculous amount of sense. Everyone will want one eventually. Some people just need to see it working first. Tesla / Writer: Annette, Designer: Janné

Tesla’s 2026.14.6.12 update with FSD 14.3.4 feels like one of those “small numbers, big difference” releases. Lane changes are way smoother now, less hesitation, more clean decisions instead of that awkward “should I, should I not” moment. It just picks a gap and goes. Parking is also noticeably better. It seems more confident about where it’s actually trying to end up, so fewer weird corrections at the last second and less circling around like it’s overthinking it. And the biggest win for me is the reduced stab braking. Way less of that random quick brake tap feeling, especially in normal traffic flow. It’s just smoother and more steady overall. Not a flashy update, but it definitely makes everyday driving feel more relaxed.

🚨 TESLA IS QUIETLY REINVENTING BATTERY MANUFACTURING WITH DRY CATHODE TECHNOLOGY. Traditional battery production still relies on slow, messy wet processes: solvents, giant drying ovens, and tricky microscopic dust that needs special handling. Tesla is now scaling a dry-electrode process for both anode and cathode in its 4680 cells eliminating solvents and dramatically simplifying the whole “oven” step. Why this matters: Cheaper, faster, smaller factories + lower energy use = meaningfully better economics for EVs. The deeper implication: We’re moving from 19th-century-style chemical baking… to modern powder-to-film engineering. The next leap in batteries might not just be better chemistry it could be better manufacturing. What do you think will this kind of process breakthrough finally make EVs obviously cheaper than gas cars? Follow for more frontier physics and future technology.

🚨 CATL SAYS LITHIUM-AIR BATTERIES COULD ONE DAY DELIVER 1600+ KM RANGE WITH ENERGY DENSITY APPROACHING PETROL. The world’s largest battery maker is pushing a radical “breathing” battery technology that replaces heavy nickel, cobalt and manganese with lithium metal and oxygen pulled directly from the air. In early lab tests, researchers have already achieved around 1,200 Wh/kg more than four times today’s best lithium-ion cells. With further development, CATL believes the technology could theoretically reach ~12,000 Wh/kg, close to the energy density of petrol itself. Why this matters: • It could slash battery weight and cost dramatically • Small EVs might achieve 1,600+ km of real-world range • It removes dependence on scarce metals like nickel and cobalt • A 1,000-cycle prototype with 1,600 km range would theoretically last 1.6 million kilometres The deeper implication: Lithium-air represents one of the few battery chemistries that could genuinely match or exceed the convenience of petrol without massive compromises. If the enormous technical hurdles (moisture sensitivity, cycle life, and oxygen management) can be solved, it wouldn’t just improve EVs it could fundamentally change what’s possible for electric aviation, long-haul transport, and portable power. We’re still very early. Current prototypes are far from commercial, and most experts expect mass production only after 2030 at the earliest. But the fact that the company producing over half the world’s high-voltage batteries is seriously pursuing this shows how transformative the payoff could be. Would you rather see solid-state batteries win the next decade, or do you think lithium-air could leapfrog them entirely? Follow for more frontier battery technology and energy breakthroughs.

🇺🇸 TESLA’S NEW APP UPDATE LETS YOUR PHONE POINT TO YOUR CAR IN REAL TIME Tesla just rolled out a new app update (v4.51.5), and honestly… this is the kind of feature people assumed should exist years ago. Now, when you open the app, you can rotate your phone and see exactly where your car is - live - with an arrow that shifts as you move. It also shows the precise distance to your car in feet, so no more wandering through parking garages like you’re in a low-budget spy movie. It’s basically Find My iPhone, but for your Model Y, and way more satisfying to use. If Tesla keeps adding features like this, the app is going to end up being more fun than the car itself.

🚨 SCIENTISTS JUST TURNED WET COFFEE GROUNDS INTO COAL-LIKE FUEL IN 90 SECONDS WITHOUT DRYING IT FIRST. Researchers in South Korea have developed a plasma-based system that converts moisture-rich coffee waste directly into high-energy biochar. The process uses flame plasma (reaching 1,470–1,650°F) to trigger rapid carbonization through a “popcorn effect,” where steam bursts inside the grounds break apart the structure and accelerate the reaction. In under two minutes, the system produces a carbon-rich material with an energy content of 29.0 MJ/kg comparable to anthracite coal while tripling the fixed carbon content and completely removing sulfur compounds. Why this matters: • Most biomass conversion methods require energy-intensive pre-drying, which this process eliminates • The resulting biochar has a much higher heating value and surface area, making it useful as fuel or for activated carbon applications • It generates minimal smoke and tar compared to traditional methods • The technology could work on other high-moisture wastes like food waste, sewage sludge, and agricultural residues The deeper implication: This represents a fast, potentially decentralized way to turn problematic organic waste into valuable resources. Instead of spending energy and money drying biomass before processing, the moisture itself becomes part of the solution. If scaled, technologies like this could help close the loop on organic waste streams while producing renewable solid fuels or advanced carbon materials with far less processing time and cost than current methods. It’s a clever example of working with the properties of waste rather than fighting them. How useful do you think rapid, drying-free waste-to-fuel systems like this could be for industries or cities dealing with large volumes of organic waste?

A PACK OF ROBOT DOGS JUST RAN A GROUP MOBILITY TEST THROUGH MUD AND STANDING WATER. Black quadrupeds, marked G01, tactical operators in black gear crouched around one on a wet, overcast field before the run starts. Then the label hits: RECON UNIT MOBILITY TEST — GROUP RUN. Several units take off together across churned mud and puddles. They don’t break formation. No slipping, no falling behind, no unit losing its footing on the uneven ground. This isn’t a single robot proving it can walk. It’s a coordinated group run — the kind of test that matters for scouting terrain a human patrol would move through slower and louder. The honest catch: bulkier, more armored builds than consumer platforms like Unitree’s Go1 usually mean less speed and battery life traded for durability. This isn’t a sprinting demo, it’s a ruggedness one. Ten years ago “robot dog” meant a single unit trotting across a clean lab floor. This is a pack of them holding formation through mud a human squad would curse at. Would a mud field even slow one of these down?

More Batteries vs. Submarines Now that the German TKMS and the French Naval Group have massively adopted lithium-ion batteries, following the Japanese lead, this is consolidating as a major trend, just as I had predicted. The next stage will be solid-state batteries, and at that point, we'll essentially be discussing only speed and submerged endurance in comparison to nuclear submarines. Since solid-state batteries are lighter, they will allow for a greater number to be installed, freeing up space for more powerful propulsion systems. Naval Group has already sold a version of the Scorpène to Indonesia capable of remaining submerged for up to 80 days. That's with lithium-ion batteries. Imagine what this could exceed, more than double, with solid-state batteries. In practical terms, a more powerful engine combined with solid-state batteries in the proportions that Naval Group is now using in the Scorpène would provide three times the speed, meaning something like 10–15 knots at constant speed while maintaining around 50 days submerged. This would give a range of 40,000–50,000 km, requiring less than one hour on the surface for a fast recharge. For speeds above 25 knots, simply adding more batteries and a better engine would suffice, as the solid-state system has high power output. All this at 15–20% of the cost of a nuclear submarine. And if the choice is to power the batteries with a micro-reactor, it would cost 25–35% of a conventional nuclear one. Then someone will say: “But a nuclear sub can stay submerged for years.” That makes no difference at all, since even with around 60 days of endurance, the crew still needs to surface to resupply provisions. The big advantages remain: battery-powered subs are superior in silence, and speed can be addressed with larger battery packs.

Just lost ALL Autopilot, FSD, even basic cruise control and Tesla Technical Assistance says they can’t do anything and apparently my car needs to go to a service center for a software update even though there are no warnings on the car. I got an FSD strike and the whole system went down. They said they can’t turn FSD back on and forgive the strikes remotely even though they did just that in January 2025 for the California fires. When I drove from Nevada into California back then my 4 strikes disappeared. Even the Tesla Technical Assistance Supervisor (who was very nice) says they have no way to fix the car remotely and it must go to a service center. Unfortunately, now I need to drive over 1000 miles with no type of cruise control or driver assistance at all. There are no warning lights on or anything of the sort. I even did a forced software update via the service mode and my Starlink, plus a few hard and soft reboots and that still did not fix it. Sadly the car is now less safe than it was a few minutes ago.

Just lost ALL Autopilot, FSD, even basic cruise control and Tesla Technical Assistance says they can’t do anything and apparently my car needs to go to a service center for a software update even though there are no warnings on the car. I got an FSD strike and the whole system went down. They said they can’t turn FSD back on and forgive the strikes remotely even though they did just that in January 2025 for the California fires.
