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 has landed a massive deal to expand its charging infrastructure for heavy-duty electric trucks — and not just theirs, but all manufacturers.
Tesla entered an agreement with Pilot Travel Centers, the largest operator of travel centers in the United States. Tesla’s Semi Chargers, which are used to charge Class 8 electric trucks, will be responsible for providing energy to various vehicles from a variety of manufacturers.
The first sites are expected to open later this Summer, and will be built at select locations along I-5 and I-10, major routes for commercial vehicles and significant logistics companies. The chargers will be available in California, Georgia, Nevada, New Mexico, and Texas.
Each station will have between four and eight chargers, delivering up to 1.2 megawatts of power at each stall.
The project is the latest in Tesla’s plans to expand Semi Charging availability. The effort is being put forth to create more opportunities for the development of sustainable logistics.
Senior Vice President of Alternative Fuels at Pilot, Shannon Sturgil, said:
“Helping to shape the future of energy is a strategic pillar in meeting the needs of our guests and the North American transportation industry. Heavy-duty charging is yet another extension of our exploration into alternative fuel offerings, and we’re happy to partner with a leader in the space that provides turnkey solutions and deploys them quickly.”
Tesla currently has 46 public Semi Charger sites in progress or planned across the United States, mostly positioned along major trucking routes and industrial areas. Perhaps the biggest bottleneck with owning an EV early on was charging availability, and that is no different with electric Class 8 trucks. They simply need an area to charge.
Tesla is spearheading the effort to expand Semicharging availability, and the latest partnership with Pilot shows the company has allies in the program.
The company plans to build 50,000 units of the Tesla Semi in the coming years, and with early adopters like PepsiCo, DHL, and others already contributing millions of miles of data, fleets are going to need reliable public charging.
🚨 Pilot working with Tesla to install and expand Semi Chargers is a perfect example of two industry leaders working together for the greater good.

Tesla is partnering with other companies for the development of the Semi program, most notably, a conglomeration with Uber was announced last year.

The ride-sharing platform plans to launch the Dedicated EV Fleet Accelerator Program, which it calls a “first-of-its-kind buyer’s program designed to make electric freight more affordable and accessible by addressing key adoption barriers.”
The Semi is one of several projects that will take Tesla into a completely different realm. Along with Optimus and its growing Energy division, the Semi will expand Tesla to new heights, and its prioritization of charging infrastructure.

Fontainebleau Loop station
The new Vegas Loop station is located on level V-1 of the Fontainebleau’s south valet area, as noted in a report from the Las Vegas Review-Journal. According to the resort, guests will be able to travel free of charge to the stations serving the Las Vegas Convention Center, as well as to Loop stations in Encore and Westgate.
The Fontainebleau station connects to the Riviera Station, which is located in the northwest parking lot of the convention center’s West Hall. From there, passengers will be able to access the greater Vegas Loop.
Vegas Loop expansion
In December, The Boring Company began offering Vegas Loop rides to and from Harry Reid International Airport. Those trips include a limited above-ground segment, following approval from the Nevada Transportation Authority to allow surface street travel tied to Loop operations.
Under the approval, airport rides are limited to no more than four miles of surface street travel, and each trip must include a tunnel segment. The Vegas Loop currently includes more than 10 miles of tunnels. From this number, about four miles of tunnels are operational.
The Boring Company President Steve Davis previously told the Review-Journal that the University Center Loop segment, which is currently under construction, is expected to open in the first quarter of 2026. That extension would allow Loop vehicles to travel beneath Paradise Road between the convention center and the airport, with a planned station located just north of Tropicana Avenue.
