Researchers at Tokamak Energy have captured for the first time a real-time, high-speed video of plasma behaviour inside their ST40 spherical tokamak, tracking visible green and red light emissions as the fusion process occurs. This visual insight comes via a camera operating at thousands of frames per second, offering unprecedented detail of how the plasma evolves, interacts with the surrounding lithium blanket and outer regions, and ultimately radiates energy. The imaging enables scientists to observe how the ultra-hot core transitions outward into cooler zones, how magnetic confinement shapes the plasma behaviour, and how impurities or outer-region interactions influence the process. By giving a ‘star-in-a-donut’ view of fusion in action, this breakthrough adds a new diagnostic tool to the development of fusion energy, helping engineers refine the magnetic confinement, optimise plasma stability and better understand the heat and light flows at play. It was slowed down by 100x. All this was for 0.3s A tokamak is one of the most advanced devices ever created to achieve controlled nuclear fusion, the same process that powers the Sun. Its goal is simple in principle but incredibly challenging in practice: heat a gas until it becomes plasma, raise that plasma to over 100 million degrees, and confine it long enough for hydrogen nuclei to fuse and release energy. Because no material container can survive such temperatures, a tokamak uses powerful magnetic fields to hold and shape the plasma like an invisible cage. The device has a distinctive doughnut-shaped (toroidal) chamber surrounded by magnetic coils. When the machine is switched on, electric currents and external magnets work together to create helical magnetic fields that trap the plasma and keep it away from the walls. As the plasma spirals around these magnetic lines, it heats up dramatically. Additional heating comes from methods like radio-frequency waves and neutral-beam injection, pushing the plasma toward the extreme temperatures needed for fusion. Inside this tightly controlled environment, hydrogen isotopes such as deuterium and tritium can collide and fuse, releasing fast neutrons and a burst of energy. The goal of tokamak research is to reach a point where the fusion reactions produce more energy than the system consumes, a milestone known as “net energy gain.” Modern machines like ITER, JET, and Tokamak Energy’s ST40 are bringing this vision closer, using advanced diagnostics, superconducting magnets, and increasingly stable plasma control. 👉

The Cybercab is aiming to produce 2 million units per year. Let this sink in. Today, Tesla produces about ~1.7 million vehicles per year total, across its entire lineup. And now Tesla is preparing to outproduce that with one single vehicle, a fully autonomous one. This is Elon and Tesla going ALL-IN on autonomy. Production is scheduled to start April 2026 at Giga Texas, with volume ramping throughout the year. And as of early 2026, Cybercab prototypes are already being tested around the U.S. The Tesla Cybercab is built from the ground up for unsupervised autonomy. There is no steering wheel and no pedals, just cameras, AI, and Tesla’s custom inference computers. No lidar and radar like other companies, just pure vision and software. Elon put it best on the Q3 2024 earnings call: “It’s not just a revolutionary vehicle design, but a revolution in vehicle manufacturing that is also coming with the Cybercab.” That quote matters a lot bc that means the entire way a vehicle is manufactured is changing with the Cybercab. Tesla is designing what Elon calls “the machine that builds the machine.” The Cybercab uses Tesla’s unboxed manufacturing process, where major sections are built in parallel instead of one long assembly line. There are fewer parts, less steps & cost, and faster scale. That’s how you make 2 million Cybercabs per year possible. FYI, this is not going to be easy though. Elon has been brutally honest about production for many years: • “Prototypes are easy, production is hard.” • “The extreme difficulty of scaling production of new technology is poorly understood. It’s 1000% to 10,000% harder than making a few prototypes.” • “For cars, it’s maybe 100 times harder to design the manufacturing system than the car itself.” He reinforced this again in January 2026 when talking about Cybercab and Optimus on 𝕏: “Initial production is always very slow and follows an S-curve. The speed of the production ramp is inversely proportional to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow - but eventually end up being insanely fast.” This is the key thing most people miss about Tesla manufacturing. Early output will be slow by design. Almost everything is new like the vehicle architecture, factory layout, AI hardware, and manufacturing flow. But once it works and clicks, it begins to scale hard. Tesla already proved they can do this. They survived Model 3 production hell. They turned Model Y into the BEST selling car in the world, of any kind. They ramped Cybertruck, which has over 30,000+ unique parts, to meaningful volume. Elon summed it up perfectly in 2024: “Compared to the insane pain of reaching high volume, positive margin production, prototypes are a piece of cake.” That’s why Tesla makes manufacturing look easy bc they already earned the scars from the last vehicle lineups. The Cybercab is aiming to be: 1/ Under $30,000 price 2/ ~$0.20 per mile operating cost 3/ 200+ mile range 4/ Up to 5x utilization vs personal cars 5/ Designed to run nearly nonstop 24/7 This is what you call manufacturing + AI + autonomy converging at scale. The competitors are still showing prototypes and demos, while Tesla is building new production lines, expanding factories, and actually building the product. I remember when Elon told me in the past that one of Tesla’s key advantage long term was going to be manufacturing technology. I get it now.

America is a failed state, taken over by organized crime. This was not an oversight hearing; it was a mafia lieutenant deliberately creating a scene to distract the cops, while the criminals escape out the back door. All of it was scripted. Count how many times she looks down while she touts the stock market with Epstein’s survivors behind her. She had at least three binders, at least one with opposition research on the Democrats. No information on survivors, or Epstein, or any actual criminals—but lots of ammunition to fire at representatives who were hired by the American people to look over her function. Worse, she had printouts of which unredacted Epstein files they had looked at, giving her advanced notice of what they might ask her—and what they know and don’t know. Surveillance state performance art. One important note, the stock market is one of the only things Trump cares about. That’s why this psychotic rant about it was written down and why she felt compelled to read it. This is a weakness being exploited by many. When it finally crashes, batten down. “The Dow is over $50,000. I don't know why you're laughing. You're a great stock trader as I hear, Raskin. The Dow is over 50,000 right now. The S&P is almost 7,000. And the Nasdaq smashing records. Americans, 401ks and retirement savings are booming. That's what we should be talking about. We should be talking about making Americans safe. We should be talking about what does a Dow have to do with anything? That's what they just asked. Are you kidding? The Dow has shattered 50,000 for the first time. This is crazy. They said it couldn't be done in four years. You have President Trump has done it in one year.”

Elon Musk said the most dangerous thing ever spoken on a stage. Not about Mars. Not about rockets. About you. Musk: “The most important mistake I see smart people making is assuming that they’re smart.” He wasn’t talking about IQ. He was talking about what happens when intelligence becomes your identity. Kasparov. Greatest chess mind in human history. Deep Blue crushed him in 1997. Your phone can now crush the world chess champion. Not a close match. Not on his best day. Literally. The world didn’t panic. It adjusted the definition. “Chess isn’t real intelligence.” Nobody flinched. Musk: “We just keep moving the goalposts.” That line should terrify you more than any AI headline ever written. Because he’s not describing technology. He’s describing a pattern that has never once been broken. Machine beats human at chess. “That’s just pattern matching.” Machine beats human at language. “That’s just autocomplete.” Machine beats human at reasoning. “That’s just…” You see where this ends. Every time a machine crosses a line we said only humans could cross, we don’t sit with it. We redraw the line. And call it nuance. That is not intelligence defending itself. That is pride bleeding out slowly enough to mistake for composure. Elon didn’t say machines are smarter to provoke a reaction. He said it because the people who refuse to hear it are the ones it’s coming for. Not from AI. From the version of themselves that would rather redefine reality than face it. That’s the real danger he was pointing at. Not the machine that outperforms you. The story you tell yourself about why it doesn’t count. One day there will be no goalpost left to move. The people who spent years moving them won’t have sharpened a thing. Too busy protecting their ego. The machine didn’t replace you. You were just standing where the goalpost used to be.

Over the top (what you see in the video) That road on the very top is the dam’s crest [the highest point of the dam, where the road runs] - 1.78 km long (about 1.1 miles, or 17 football fields laid end to end). Imagine standing at one goalpost and looking across 17 full fields in a row - that’s the length you see. The crest sits at ~645 meters above sea level [the height compared to sea level]. Just below that is the reservoir’s normal full level [the usual maximum water height] at ~640 m - picture a massive lake stretched out behind you, nearly as high as the road itself. In the center of the main dam, the crest crosses a 216-meter bridge over the spillway opening [the structure that lets extra water out safely]. From this video angle, you might not see it clearly - but trust me, the spillway is there. Back to the bridge: it’s about 11.6 meters wide, wide enough for two cars or trucks to pass with space to spare. It rests on five reinforced-concrete piers [thick vertical supports made of concrete and steel]. Those five “openings” under the deck aren’t separate spillways - they’re the bridge supports holding it up. The “middle ramp” under the crest Now, let’s talk about the middle ramp. Picture a wide, stepped ramp running down the face of the dam beneath the bridge - that’s the auxiliary ungated spillway [an extra water-release path without gates], also called the middle spillway. It’s like the dam’s backup path for water when the main spillway is already in use. It only runs when the reservoir is at or near full and incoming water is more than the main spillway can release. Think of it like the overflow lip on a bathtub - it’s dry most of the time, but when the tub fills to the brim, the water flows over this edge. Its design discharge [maximum flow] is ~2,800 m³/s - roughly 1.1 Olympic swimming pools every second (1 pool ≈ 2,500 m³). Imagine an entire Olympic pool tipping over every single second and rushing down those concrete steps. How GERD handles floods You might be wondering - how does the dam actually manage floods? Well, it’s got a layered system [multiple ways to release water safely]: • Main gated spillway (left bank): six giant gates, ~14,500 m³/s capacity - about 5.8 Olympic pools per second pouring out. •Auxiliary ungated spillway (center): runs when the lake is high enough to overflow it. •Emergency spillway (saddle dam): for rare, extreme floods [about a 1,000-year event - the biggest flood expected in that time]. Together, these can pass a Probable Maximum Flood [worst-case possible flood] of about 30,200 m³/s. • Two low-level outlets (main dam): controlled releases [water pipes with gates that can be opened and closed] up to ~830 m³/s - that’s 830,000 one-liter bottles of water each second. Quick comparisons to bring the numbers to life • Crest length (~1.78 km): about a 20-minute walk from one end to the other. • Crest elevation (~645 m): the truck in your video is driving at a height equal to two downtown high-rises stacked above the riverbed. • Main spillway (~14,500 m³/s): enough to fill 6 Olympic pools every second in a major flood. • Auxiliary spillway (~2,800 m³/s): enough to fill 1.1 Olympic pools each second. • Low-level outlets (~830 m³/s): equal to 830,000 bottles of water rushing out every second. That truck isn’t just driving on a road - it’s crossing the crown [topmost part] of one of Africa’s largest dams, built to control floods, store water, and power the future. Above is the two-lane crest, and below, the spillways and outlets wait quietly until it’s time to release the river’s force. #Ethiopia #BlueNile #Hydropower #Engineering #BenishangulGumuz #Spillway #CrestBridge #GERD #RenaissanceDam

🚨 Chinese developers just dropped a 4-minute video and GitHub Repo that’s exploding the internet. They opened a terminal… and in just 4 minutes built a team of 7 AI agents that completely replace an entire customer support department. Cost? > Only $50 a month. > One agent classifies tickets. > One reads the knowledge base. > One handles billing. > One watches the customer’s tone. > One decides when to escalate. > One writes the reports. And one agent runs all the other six. The results? Brutal. 1,200 tickets a day per agent. More than a full call center of 8 human operators. Companies used to spend $25,000–$40,000 per month on salaries. Now they pay just $50 for the API. The video hit 4 million views in 72 hours. Every CEO in China was forwarding it. Every support team in America is panicking. While the West is still debating “Will AI replace jobs?”… China just published the actual manual on how to fire an entire department. But wait it gets way crazier. Pause the video at 0:39. Ignore the guy in the blue shirt. Look at the second monitor on the right. That’s not a support dashboard. That’s a live trading wallet. > Username: gabagool22 > $868,862 profit > 28,620 predictions > All on Bitcoin > All 15-minute windows Every single one green. Profile: Copying his trades: GitHub: The comment section turned into a detective agency. People slowed the video to 0.5x, screenshot every frame, and stitched the full wallet together from just 6 seconds of background footage. Entry prices: 2 to 10 cents. Payouts: thousands of dollars. Not one red trade in 28,620 bets. Biggest single win? $4,696 in one 15-minute window. Here’s the insane part: The 7 AI agents save a company $40K a month. The wallet on their second monitor makes that money in one good week. They were teaching the world how to replace humans with cheap AI. Meanwhile, their own setup behind the camera was already replacing traders. They deleted the wallet zoom in the next upload. Too late. Someone screen-recorded it anyway. The tutorial got 4 million views. The secret wallet clip got another 800K. Now 727K people are staring at that wallet. The 7 agents are still answering tickets somewhere for $50 a month. But the wallet behind them? It doesn’t need 7 agents. It only needs one. And that one was already running while they were filming. Mind officially blown Screenshot it. Send it to a friend. And ask yourself: what’s running on your second monitor?

The speed of light is too slow. That is the buried physics problem inside Elon Musk's plan for 1 million AI satellites, and his solution is a constellation that refuses to think together. The world pictures the same machine, a million Starlink satellites wired into one giant brain in the sky. Physics vetoes it on contact. Inside a single ground rack, AI chips exchange 260 terabytes a second across 2 meters of copper and synchronize in millionths of a second. Between satellites hundreds of kilometers apart, light itself needs a full millisecond to cross the gap, a thousand times too slow. The fastest thing that exists cannot keep up with the conversation inside one server rack. A computer cannot be stretched across the sky. Think about it. Maybe Elon will agree. So SpaceX collapsed the computer into the satellite. The spacecraft is the rack. Each AI1 carries a complete data center rack's worth of compute, 120 kilowatts on average, on wings spanning 70 meters, wider than a Boeing 747 jet. The spec Elon posted today pushes further, a full NVIDIA Rubin rack in every Starlink satellite, 72 GPUs, 250 kilowatts peak. Nothing important ever leaves the machine. The weights, the memory, the model itself, all stay home. The laser links between Starlink satellites carry questions and finished answers, never the thinking in between. For 20 odd years computing moved in one direction, toward the cloud, thousands of machines pretending to be one. Orbit just reversed it. A million computers pretending to be nothing but themselves. The moat is not beating the speed of light. If you think about it it is all about building the machine so the most valuable data never enters the race. Two prototypes fly in early 2027. The rocket that has to carry them flies tonight. The piece works out whether the sky becomes one mind or a million. My money is on Elon!
