Elon Musk has just confirmed that the limits for Grok Imagine will be increased. This is good news for SuperGrok / X Premium+ users. It’s another proof that xAI is listening to its users concerns and taking them seriously.

🔋 Mitochondria run their core power system using bacterial-style DNA. 🧬 But they need your nuclear DNA for support, repair, and growth. Think of it like a battery with its own mini-engine — it sparks on its own, but the car (your cell) builds and maintains it. Bottom line: Mitochondria are semi-independent — powered by ancient bacterial genes, guided by your human ones.

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

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.

One may've own vision. But this arrogance isn't acceptable. People've their own choice depending on their financial pockets. What choice is HE giving to replace Diesel Vehicles? EVs? How many battery stations has HE developed? EVs are more hazardous to environment than diesel vehicles. Has HE developed its battery scrapping policy? Has HE thought of undisposable scrap which EVs are going to leave behind? Better solution is Hydrogen Fuel & Bio Fuel. What has HE done on it? Keep aside this arrogance which hurts #Modi Sarkar's image. Or is it deliberate as HE knows that HIS friends in Media & Opposition will never target HIM for best reasons known to all?

‼️🇦🇪🇰🇷🇮🇷🇺🇸 According to South Korean news agency Yonhap, the UAE has dispatched several C-17 transport aircraft to Daegu Air Base in South Korea to urgently airlift batteries of the Korean-made Cheongung-II interceptor missile system. A total of eight UAE transport aircraft are expected to be deployed sequentially for the transport, with one C-17 already spotted on the runway at Daegu Air Base. The battery being transferred is the UAE's third Cheongung-II battery, being delivered approximately one month ahead of schedule. Dozens of interceptor missiles are also being transported alongside the battery. During recent Iranian missile attacks on neighboring countries, the two deployed Cheongung-II batteries were activated alongside US Patriot and Israeli Arrow systems, with at least 60 interceptor missiles fired in combat.

Felt incredibly rough this morning 🤧 but had “work” to do this afternoon. That involved taking the Autobiography Range Rover and swapping it for the P400X 130 Defender (394bhp) and collecting a 65” TV 📺. This did double up as part of my transport management as the Defender needed a good run out to charge the battery due to sitting around for almost 2 months as much of the fleet has done🪫 Mad what I get paid to do at times but I love it 😆☺️

Those investing in submarines today may be wasting money. A Virginia-class submarine, powered by an S9G reactor, has a submerged displacement of around 10,000 tons and costs approximately $4–5.8 billion. Its top speed is over 30 knots. Now imagine a much smaller reactor, with power and weight around 15% of the Virginia's, used solely to continuously recharge a solid-state battery bank. Solid-state batteries weigh about half as much as lithium-ion batteries while offering 2-3x more energy capacity. In practice, this means that with the same battery weight, such a sub could achieve roughly 3x the energy gain, In terms of speed, solid-state batteries deliver double or higher discharge rates (potentially 10–20C vs. 5–10C for lithium-ion), ideal for sustained sprints above 30 knots lasting many days and a cruising speed around 25 knots. All this with 15% less overall weight, much quieter operation on batteries alone, and the same endurance as a conventional nuclear sub. And the cost? A micro-reactor would be 15–25% the price of a conventional one, small, modular, low-temperature/low-pressure. This means that when a more modern reactor is needed, you simply swap the module. A micro-reactor paired with solid-state batteries could make a Virginia-class sub $1.2-1.6 billion cheaper, quieter, and leave far more space for weapons, additional batteries, or crew comfort. That's why this system would put all existing submarines at a disadvantage in terms of cost, space, and stealth. Those not adopting micro nuclear reactors can follow what the Germans, Japanese, and French are doing. The Japanese pioneered lithium-ion batteries with diesel chargers, giving their submarines excellent value for money. The Germans chose a fuel cell AIP system to recharge lithium-ion batteries, while the French opted for a similar Japanese-style approach with a battery configuration allowing up to 80 days endurance, making the new Scorpène highly competitive. Starting around 2030, production will shift to solid-state batteries, tripling the capacity of these conventional submarines and enabling silent navigation at around 25 knots for days,making them superior in stealth and speed to many nuclear submarines currently in service. Submarines powered by solid-state batteries, recharged via micro-reactors, fuel cells, or diesel, will be superior: better armed, cheaper, and stealthier than anything we know today.

This is interesting Cultist Circle Recipe in #EscapefromTarkov . Similar concept where non-FIR turns into FIR Golden Dumbbell for Kappa Quest. (image 1) If you sacrifice 'Tank Battery (6-STEN-140-M military battery)', you get 'old house toilet key' after 66 minute (image 2) Old house is in Train Depot in woods where you can only access through BTR service. What's interesting is that 'old house toilet key' now unlocks the locked place in old house, which will always spawn Tank Battery. (clip 1) Since you arrived at old house by BTR, BTR will be right outside of the house. So you can haul the Tank battery to BTR, for #1. Give it to him for 'Battery Change' quest which requires Tank battery delivery to BTR. or 2. Send it via BTR service to your hideout to have safe delivery FIR tank battery. Generating FIR Tank battery from non-FIR tank battery.

🚨 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.

🚨 RESEARCHERS JUST MADE WATER-BASED BATTERIES LAST OVER 2,800 HOURS WITH RECORD CAPACITY. A team in South Korea has developed a simple zwitterionic electrolyte additive that dramatically improves the performance of aqueous (water-based) batteries a technology long seen as a safer, cheaper, and more environmentally friendly alternative to lithium-ion. The additive forms tiny nanostructures that guide zinc to deposit evenly on the electrode and create a protective layer that prevents corrosion and unwanted side reactions with water. This solves two of the biggest problems that have limited aqueous batteries: uneven metal buildup and rapid capacity fade. In testing, the modified batteries achieved a world-leading areal capacity of 8.10 mAh cm⁻² and ran stably for more than 2,800 hours. Why this matters: • Aqueous batteries are non-flammable and use abundant, low-cost materials, but have historically suffered from poor lifespan and performance • This approach improves both cycle life and capacity at the same time — something many previous solutions struggled to achieve together • It uses a simple additive rather than requiring expensive new materials or complex manufacturing changes • The technology is particularly relevant for large-scale energy storage needed for renewables and AI data centers The deeper implication: We’re getting closer to making safe, scalable, and affordable grid storage a reality. While lithium-ion still dominates, aqueous batteries could become a strong contender for stationary storage where safety, cost, and longevity matter more than energy density. A small molecular tweak unlocking major performance gains shows how materials engineering at the nanoscale can have outsized real-world impact. This is the kind of incremental but meaningful progress that compounds over time. How important do you think safer, water-based batteries will be for the future energy grid compared to improving lithium-ion or other alternatives?

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.

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.
