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.

Tesla’s $2.9 billion bet: Why Elon Musk is turning to China to build America’s solar future
Tesla looks to bring solar manufacturing to the US, with latest $2.9 billion bet to acquire Chinese solar equipment.
Tesla is reportedly in talks to purchase $2.9 billion worth of solar manufacturing equipment from a group of Chinese suppliers, including Suzhou Maxwell Technologies, which is the world’s largest producer of screen-printing equipment used in solar cell production. According to Reuters sources, the equipment is expected to be delivered before autumn and shipped to Texas, where Tesla plans to anchor its next phase of domestic solar production.
The move is a direct extension of a vision Elon Musk has been building for months. At the World Economic Forum in Davos this past January, Musk announced that both Tesla and SpaceX were independently working to establish 100 gigawatts of annual solar manufacturing capacity inside the United States. Days later, on Tesla’s Q4 2025 earnings call, he made the ambition concrete: “We’re going to work toward getting 100 GW a year of solar cell production, integrating across the entire supply chain from raw materials all the way to finished solar panels.”
Job postings on Tesla’s website reflect that same target, with language explicitly calling for 100 GW of “solar manufacturing from raw materials on American soil before the end of 2028.”

The urgency behind the latest solar manufacturing target is rooted in a set of rapidly emerging pressures related to AI and Tesla’s own energy business. U.S. power consumption hit its second consecutive record high in 2025 and is projected to climb further through 2026 and 2027, driven largely by the explosion in AI data centers and the broader electrification of transportation. Tesla’s own energy division, which produces the Megapack utility-scale battery storage system, has been growing rapidly, and solar supply is a critical companion component for the business to scale. Musk has argued that solar is not just a clean energy option but the only one that makes economic sense at the scale AI infrastructure demands.

Ironically, the path to domestic solar independence currently runs through China. Sort of.
Despite Tesla’s stated push to localize its supply chain, mirrored recently by the company’s plan for a $4.3 billion LFP battery manufacturing partnership with LG Energy Solution in Michigan, Tesla still relies on China-based suppliers to keep its cost structure intact.
The $2.9 billion equipment deal underscores a tension Musk himself acknowledged at Davos: “Unfortunately, in the U.S. the tariff barriers for solar are extremely high and that makes the economics of deploying solar artificially high, because China makes almost all the solar.” Building the factory in America requires buying the machinery from the country Tesla is trying to reduce its dependence on.

The regulatory pathway adds another layer of complexity. Suzhou Maxwell has been seeking export approval from China’s commerce ministry, and it remains unclear how quickly that clearance will come. Still, the market has already reacted, with shares in the Chinese firms reportedly involved in the talks surged more than 7% following the Reuters report that broke the story.
Whether Tesla can hit its 2028 target of 100GW of solar manufacturing remains an open question. Though that scale may seem staggering, especially in such a short timeframe, we know that Musk has a documented history of “always pulling it off” in the face of ambitious deadlines that may slip. But, rest assured – it’ll get done.

Elon Musk reveals date of Tesla Full Self-Driving’s next massive release
Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.
Tesla CEO Elon Musk revealed the date of Full Self-Driving’s next massive release: v14.3.
For months, Tesla owners with Hardware 4 have been utilizing Full Self-Driving v14.2 and subsequent releases. Currently, the most up-to-date FSD version is v14.2.2.5, which has definitely brought out mixed reviews. With releases, some things get better, and other things might regress slightly.
For the most part, things are better in terms of overall behavior.
However, many owners have been looking forward to the next release, which is v14.3, about which Musk has said many great things. Back in November, Musk said that v14.3 “is where the last big piece of the puzzle lands.”
He added:
“We’re gonna add a lot of reasoning and RL (reinforcement learning). To get to serious scale, Tesla will probably need to build a giant chip fab. To have a few hundred gigawatts of AI chips per year, I don’t see that capability coming online fast enough, so we will probably have to build a fab.”
Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.
Tesla Full Self-Driving v14.2 is a considerable improvement from early versions of the suite, but we have written about the somewhat confusing updates that have come with recent versions.

They’ve been incredibly difficult to gauge in terms of progress because some things have gotten better, but there seems to be some real regression on a handful of things, especially with confidence and assertiveness.
Musk confirmed today on X that Tesla is already testing v14.3 internally right now. It will hit a wide release “in a few weeks,” so we should probably expect it by late April.
It’s in testing right now. Wide release in a few weeks.

Overall, there are high hopes that v14.3 could be a true game changer for Tesla Full Self-Driving, as many believe it could be the version that Robotaxis in Austin, Texas, some of which are driverless and unsupervised, are running.
It could also include some major additions, including “Banish,” also referred to as “Reverse Summon,” which would go find a parking spot after dropping occupants off at their destination.
What Tesla will roll out, and when exactly it arrives, all remain to be seen, but fans have been ready for a new version as v14.2.2.5 has definitely run its course. We have had a lot of readers tell us their biggest request is to fix Navigation errors, which seem to be one of the most universal complaints among daily FSD users.
