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.

Honda and Acura electric vehicles will soon be plugging into Tesla’s Supercharger network, with approved NACS-CCS adapters rolling out to Prologue and ZDX owners in June 2025.

This provides Honda and Acura EVs access to over 20,000 Superchargers across the United States.

Adapters Ensure Safety

Starting June 2025, Honda Prologue and Acura ZDX drivers can acquire a Honda-approved NACS-CCS DC fast-charging adapter at authorized U.S. dealerships, with pricing set closer to launch. Tested for safety and compatibility, it’s the only DC adapter that Honda recommends for its EVs at NACS stations, as noted in a press release.

Ryan Harty, assistant vice president of Sustainability & Business Development at American Honda Motor Co., Inc., shared his thoughts on the matter. “Adding Tesla Supercharger network access to the charging networks already available to our EV customers means industry-leading fast-charging access for Honda and Acura EV drivers,” he said.

Tesla requires approved NACS adapters at its Superchargers, and Honda strongly recommends that Prologue and ZDX owners use approved adapters. Honda also noted that damage caused by using unapproved adapters may not be covered by cars’ limited warranties.

Honda’s Big Charging Vision by 2030

Honda’s not stopping at Tesla’s network. By 2030, Prologue and ZDX owners are expected to tap roughly 100,000 DC fast-charge points across North America, blending Tesla Superchargers with IONNA’s new network, EVgo, and Electrify America.

“By the end of this decade, we strive to provide Honda and Acura EV drivers with the most convenient and easy charging at more than 100,000 charge points nationwide, helping people choose to purchase an EV for the many benefits of driving one,” Harty stated.

“Tesla Takedown” movement plans 500 protests in 277 stores, Superchargers

Rep. Jasmine Crockett (D-TX) stated that March 29 is her birthday, and “all I want to see happen on my birthday is for Elon to be taken down.”

The “Tesla Takedown” group is aiming to hold its “biggest day of action” in over 277 Tesla stores, as well as Supercharger stations.

During a mass call on Wednesday, organizers, filmmakers, members of Congress, and other key individuals banded together to call for a mass demonstration against the electric vehicle maker this coming March 29, as noted in a report from The Verge.

Tesla Takedown

The Tesla Takedown movement emerged from critics’ opposition to Elon Musk’s increasingly political nature, his close relationship with U.S. President Donald Trump, and his work with the Department of Government Efficiency (DOGE), which is aimed at cutting unnecessary government spending and waste. Members of the Tesla Takedown movement have targeted the EV maker since a notable portion of Musk’s net worth is tied to his Tesla holdings.

Unfortunately, protests against the electric vehicle maker and Musk have become increasingly violent, with Tesla stores being shot up and vehicles being burned in acts of arson. Supercharger stations have also been targeted in arson attacks. Tesla owners’ vehicles have been vandalized and set on fire as well.

Amidst these attacks, Trump has noted that he considers such actions as domestic terrorism. Attorney General Pam Bondi has also noted that those behind the arson and vandalism against Teslas will be caught and persecuted.

“No Conspiracy,” but Still Wishing For Musk Takedown

During the hour-long call, actor and filmmaker Alex Winter, who promoted the Tesla Takedown movement on BlueSky, stated that there is no conspiracy to take down the electric vehicle maker. “There is no conspiracy, there is no well-funded cabal. It’s just Elon Musk who has taken Tesla down,” he said.

Alice Hu, executive director of Planet Over Profit, noted that protesters are looking to hold over 500 events across the world on March 29, with 277 Tesla stores expected to see demonstrations. She also stated that protesters should feel free to demonstrate at Supercharger stations.

“We need to show Elon that he can throw a tantrum online because his stocks are tanking. He can get Trump to put on a humiliating used car show in front of the White House. These wannabe authoritarians can try to intimidate us from exercising our First Amendment rights, but they can’t stop us from fighting back,” Hu said.

Rep. Jasmine Crockett (D-TX) called for participants to fight, though she was quick to state that protests should be nonviolent. “The things that we’re fighting for, we are fighting for our country. We’re fighting for democracy. We’re fighting for our freedoms. And when I say fighting, I’m saying that figuratively. Obviously, everything that I am promoting is nonviolent,” she said. Interestingly enough, Crockett also stated that March 29 is her birthday, and “all I want to see happen on my birthday is for Elon to be taken down.”

Tesla CEO Elon Musk has announced two measures the company is taking to fight the vandalism that is going on at showrooms across the country as vehicles and even structures have been lit on fire, spray painted, or damaged by various means by those who oppose him or the automaker.

As attacks against Tesla owners and even the company directly continue to occur across the country, people have been wondering what the company will do to fight back. After President Trump and other members of the administration stated that attacks against the company would be treated as domestic terrorism, many thought things would cool down.

However, things have only intensified. Although several of the perpetrators have been arrested and are facing consequences, it seems the severity of the attacks has only gotten worse. Things like Molotov cocktails have been employed by protestors to show their distaste for the company.

Now, Musk is detailing several things Tesla is doing at its showrooms in hopes of ending everything that has gone on and persisted due to the resistance from those who oppose the automaker.

Musk says that Tesla is now ramping up security at its showrooms and is now using Sentry Mode on all vehicles to help catch perpetrators in the act.

We have seen security beef up in several high-profile locations, including Tesla’s Las Vegas location on Sahara Blvd., where Las Vegas Metro Police were spotted yesterday keeping things under control:

🚨 Tesla showrooms in Las Vegas have security in the form of the LVMPD

It is literal insanity that we have cops guarding Tesla dealers because people can’t have a different opinion in peace https://t.co/aunbNmWRuK

Additionally, Sentry Mode has already done a great job of catching several perpetrators in the act, like this one who was recently caught, arrested, and now faces up to 18 months in jail for keying a swastika in a Tesla:

Not smart to attack Teslas

Hopefully, these two measures can eliminate most of the issues Tesla has had at its showrooms. If not, there will likely be follow-up measures utilized by Tesla in hopes of ending this senseless vandalism.
