Advancement in nuclear fusion tech continues transition to clean energy future
The development of unlimited, carbon-neutral, and safe energy through nuclear fusion is expanding around the world, and scientists at the Atomic Energy Authority in the United Kingdom (AEA) have recently cleared one more key hurdle to making it a commercial reality: exhausting gas that’s hotter than the Sun. The hot plasma created during fusion power generation needs to cool down as it’s being used, but at its extreme temperatures, there aren’t any materials available to withstand the heat. Now, that problem appears to have been solved.
The AEA team’s answer to the heat issue is a “sacrificial wall” design which will require replacement every few years. Plasma will be moved down a path within its fusion generator’s holding device to cool it slightly before coming into contact with a specially designed wall for the remainder of the cooling process. However, even at a lower temperature, the heat will degrade the wall’s integrity over time and need to be changed. With the first nuclear fusion reactor set to turn on in seven years, AEA’s fusion exhaust system may be one of the developments that keeps it on schedule.
It’s said that imitation is the sincerest form of flattery, and recent fusion energy developments show that sentiment’s considerations don’t remain within the bounds of Earth. At about 90 million miles away, our Sun is essentially a fusion reactor in the sky, its large size creating enough gravity to force atoms together at its core and release massive amounts of energy. Artificially reproducing the conditions needed for this kind of generation is tough, but the attempt has been going on since the 1960s. The AEA is representative of one agency in a global endeavor.
The most advanced nuclear fusion project today is ITER, the International Nuclear Fusion Research experimental reactor in southern France, which hosts scientists from 35 countries dedicated to achieving the first ever positive fusion energy production. Their device is called a “tokamak”, and its structure is something like a flattened donut (torus) encapsulated by rings of powerful magnetic coils. The magnetic fields generated by the coils both suspend the plasma created by extreme heat and squeeze the plasma into a small space to create the fusion reactions. ITER is scheduled to turn its reactor on in 2025.

Creating fusion in a laboratory involves two primary parts: 1) creating plasma, a soup of electrons and nuclei released from their atomic structures due to extremely high temperatures; and 2) merging the nuclei of two different types of atoms, generally different forms of hydrogen. The heat in a tokamak is generated from both the magnetic field movement and external heating devices, and the nuclei merge is achieved by squeezing the plasma using those same magnetic fields into a constricted area to encourage collisions. Essentially, the high heat excites the atomic particles, speeding their motion, and their energetic movements within the magnetically confined area significantly increases the likelihood the nuclei will crash and fuse together. When this fusion occurs, a massive amount of energy is released, the object of desire for all involved in this field of research.
The amount of heat needed to convince atoms to release their electrons and form plasma is in the range of millions of degrees Celsius, the core of the Sun itself being 15 million degrees. Without high gravity to aid with squeezing plasma, as in the Sun’s case at 27 times the gravity of Earth, reactors on our planet need to heat well beyond the Sun’s temperature to ensure the atomic particles in the plasma collide and fuse. ITER’s tokamak heats to 100 million degrees Celsius.

All of this heating and magnetic control requires its own energy input, and this is where the current state of fusion energy development is focused. The ratio of energy used and energy produced is called “Q”, the desired amount aimed for by scientists in the field being 10:1. When ten times the energy is produced by nuclear fusion than used to produce it, it will have advanced to a level ready for further development as an alternative power source, or so goes the thinking. ITER’s specific goal is to produce 500 MW of fusion power from 50 MW of heating power.
Once energy is released from the fusion process, it can then be captured to create steam to power generators currently using other power sources such as coal and natural gas. This is another benefit purported benefit of fusion power; it can plug directly into existing power grids, minimizing any disruptions or requirements for new equipment. Combined with the abundant availability of hydrogen and the lack of greenhouses gases or radioactive waste, there are high hopes for fusion’s future as an all-in-one energy solution.

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 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
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.
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.
People wonder if FSD is safe on narrow European roads. Well have a look what it did when a tractor took up more than half of the road or when overtaking bicycles with fast oncoming traffic. pic.twitter.com/z37Csa09sP

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 utilizes its ‘Rave Cave’ for new awesome safety feature
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 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.
A lot of CRAZY new features coming with Tesla’s 2026 Spring Update, including a new FSD app!
– Self-Driving App (AI4 hardware): New app in App Launcher > Self-Driving for one-tap FSD subscriptions, activation guides, and ongoing stats.

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.
