Fusion power is still decades and billions of dollars away, even after this week’s major scientific breakthrough
The nuclear fusion breakthrough heralded on Tuesday was a historic event, culminating decades of research.
At the same time, fusion power will not be contributing electricity to any power grid for at least a decade, according to most industry watchers. To get there, there will have to be many more technical breakthroughs beyond what was celebrated on Tuesday — and the money to fund them.
Just after 1 a.m. on Monday, Dec. 5, researchers at the Lawrence Livermore National Laboratory in California executed a successful experiment to produce more energy from a nuclear fusion reaction than went into the lasers used to power the reaction.
“We got out 3.15 megajoules, we put in 2.05 megajoules in the laser,” said Mark Herrmann, a program director at Lawrence Livermore, on Tuesday. “That’s never been done before in any fusion laboratory anywhere in the world. So it’s super exciting.”
In a technical panel discussion after the main press announcement on Tuesday, scientists on the team recounted their reactions on learning the news.
Tammy Ma, a laser-plasma physicist at the lab, was waiting in an airport when her boss called her. “I burst into tears. I was jumping up and down in the waiting area, the crazy person.”
It took about 300 megajoules of energy from the electricity grid to fire the laser that was used in the experiment, said Herrmann on Tuesday. That’s equivalent to what is included in about two-and-a-half gallons of gasoline.
All of that energy went into the laser fusion reaction that showed net gain of about 1.1 megajoules — enough energy to boil a teakettle maybe two or three times.
“This is a science achievement, not a practical one,” Omar A. Hurricane, a chief scientist at Lawrence Livermore, told CNBC.
But the amount of energy isn’t the point. “The laser wasn’t designed to be efficient. The laser was designed to give us as much juice as possible to make this incredible conditions possible,” Herrmann said. “So there are many, many steps that would have to be made in order to get to an inertial fusion as an energy source.”
That’s partly because National Ignition Facility, where the demonstration took place, is 20 years old, and was constructed using technological components made in the 1980s and 1990s. Laser technology has progressed significantly since then.
The reason for the celebration was simply that energy was created at all.
“It’s exciting because it proves that fusion can work, and it opens the floodgates to further interest, investment, and innovation toward turning fusion into a power source,” said Arthur Turrell, a plasma physicist and the author of The Star Builders.

Researchers have achieved a breakthrough regarding nuclear fusion, a technology seen as a possible revolutionary alternative power source.

The industry will need a whole lot more firsts
Progress is happening fast, but the scope of the problem is immense.
A little more than a year ago, in August 2021, the same laboratory had another breakthrough that Hurricane billed as “a Wright Brothers moment.” That experiment achieved fusion ignition in a controlled environment for the first time, but the total energy that was put into the reaction was less than what came out.
“A plasma is said to ignite when the energy gain due to fusion reactions exceeds all energy losses, resulting in a rapid escalation of temperature, pressure, and fusion energy yield. Previously this had only been achieved in the detonation of nuclear weapons,” explained Pravesh Patel, the scientific director of the fusion startup Focused Energy and a former scientist at Lawrence Livermore.
In that 2021 experiment, the energy gain was 0.73. The Dec. 5 experiment was the first time an energy gain over 1.0 was achieved — specifically, an energy gain of 1.5.
“Getting anything above 1x is everything psychologically because it shows fusion can be a (net) source of energy!” Turrell told CNBC. “To put it another way, it is this moment when >1x is achieved that will make it into the history books.”

Patel expects to see energy gain of 4 or 5 coming out of the team at Lawrence Livermore eventually. But to make commercial fusion with lasers will require an energy gain of approximately 100x, Patel said.
To get to that level will require new facilities and new technology developments of component parts, such as efficient diode-pumped lasers.
“That will need progress in so-called ‘advanced concepts’ such as fast ignition or shock ignition, that are designed for high gain. Those concepts require new facilities to be built, so a breakthrough there will take until later this decade,” Patel said.
Moritz von der Linden, CEO of startup Marvel Fusion, also emphasized the importance of new lasers.
“Newest generation laser systems at other or new facilities must show that they can easily fire 10 laser pulses per second with high energies. Also, the targets must have an efficient energy absorption rate and be mass producible,” Linden told CNBC in a statement. “Only with optimized targets and latest-generation laser systems is it possible to show a net energy gain — the next truly revolutionary milestone. That will be one of the toughest engineering challenges imaginable to mankind.”

Funding will have to increase dramatically
While it will be more than a decade until fusion is commercialized, investors are already pouring money into the sector: The private fusion industry has seen almost $5 billion in investment, according to the industry trade group, the Fusion Industry Association, and more than half of that has been since since the second quarter of 2021.
Most of that investment gone toward a different approach called magnetic fusion, which uses a donut-shaped device called a tokamak. Only about $180 million has gone into inertial fusion, the approach that typically uses lasers, according to Fusion Industry Association CEO Andrew Holland.
Regardless of the approach, Tuesday’s announcement is significant for the industry as a whole, according to Dennis Whyte, who works at MIT and cofounded Commonwealth Fusion Systems (CFS), a leading startup working with tokamak-based fusion that’s raised more than $2 billion.
“While the technology readiness of tokamaks is higher for energy systems, the breakthrough announced yesterday was a scientific one confirming that net energy can be produced by the fusion fuels,” Whyte told CNBC. “So this is an important result for all fusion endeavors.”
In September, the Department of Energy announced $50 million will go toward private fusion companies in public-private partnerships.
That funding is a critical step for fusion to be commercial by the late 2030s, where most fusion industry watchers are aiming, Patel told CNBC, but it is not enough. There needs to be between 10 and 100 times as much investment to “meaningfully accelerate the time it will take to commercialize fusion and reduce our dependency on fossil fuels,” Patel told CNBC.
Perhaps the greatest criticism of fusion is that it will take too long to come online to be helpful in responding to climate change.
But industry participants believe that bold action can succeed in time.
“In March, the White House agreed and launched a program to work together with the private sector to shoot for a ‘pilot plant’ with a bold decadal plan,” Whyte told CNBC. “Why this timeline? Well if you work backwards from 2050, the math tells you when you need the pilot plant if you want fusion to play a role in combatting climate change, based on the scale-up times that will be required. This will be hard, but worthwhile to attempt.”
For years, Tesla has been the go-to EV recommendation for “normals” looking for a painless, low-effort experience from their first electric cars. In light of questionable recalls and its CEO’s recent involvement in controversial politics, however, people are starting to distance themselves from the trailblazing company.
All that begs the question: what should we recommend to EV noobs now?
Despite early quality issues and ongoing service headaches, the groundbreaking S3XY lineup of EVs have always had a secret weapon in the form of the Tesla Supercharger network.
That network of dependable high-speed chargers, paired with solid app integration that makes it easy for Tesla drivers to find available chargers just about anywhere in the US, gave the brand a leg up – but no more. By opening up the Supercharger network to brands like Ford, Hyundai, Kia, and others, Tesla has given away its biggest competitive advantage.
Add in charging and route-planning apps like Chargeway, that make navigating the transition from CCS to NACS easier than ever with its intuitive colors and numbers and easy on/off switch for vehicles equipped with NACS adapters, and it feels like the time is right to start suggesting alternatives to the old EV industry stalwarts. As such, that’s exactly what I’m going to do.
Here, then, are my picks for the best Tesla S3XY (and Cybertruck) alternatives you can buy.
Less Model S, more Lucid Air
Developed by OG Tesla Model S engineers with tunes from Annie Get Your Gun playing continuously in their heads, the Lucid Air promises to be the car Tesla should and could have built, if only Elon had listened to the engineers.
With panel fit, material finish, and overall build quality that’s at least as good as anything else in the automotive space, the Lucid Air is a compelling alternative to the Model S at every price level – and I, for one, would take a “too f@#king fast” Lucid Air Sapphire over an “as seen on TV” Model S Plaid any day of the week. And, with Supercharger access reportedly coming later this quarter, Air buyers will have every advantage the Supercharger Network can provide.
HONORABLE MENTIONS
Less Model 3, more Hyundai IONIQ 6
Hyundai has been absolutely killing it these days, with EVs driving record sales and new models earning rave reviews from the automotive press. Even in that company the IONIQ 6 stands out, with up to 338 miles of EPA-rated range and lickety-quick 350 kW charging available to make road tripping easy – especially now that the aerodynamically efficient IONIQ 6 has Supercharger access through a NACS adapter (the 2026 “facelift” models get a NACS port as standard).
The company’s sole electric sedan hasn’t seen the same sales success as IONIQ 5, of course – but that has more to do with America’s insatiable lust for crossovers and SUVs than any shortcoming inherent in the IONIQ 6 itself. All the same, Hyundai is helping dealers clear out its remaining 2024 and ’25 models with 0% financing for up to 48 months through June 2nd.
HONORABLE MENTIONS
Less Model X, more Volvo EX90
Once upon a time, Mrs. Jo Borrás and I were shopping three-row SUVs and found ourselves genuinely drawn to the then-new Model X. Back then it was the only three-row EV on the market, but it wasn’t Elon’s antics or access to charging, or even the Model X’s premium pricing that squirreled the deal. It was the stupid doors.
We went with the similarly new Volvo XC90 T8 in denim blue, and followed up the big PHEV with a second, three years later, in Osmium Gray. When it’s time to replace this one, you can just about bet your house that the new 510 hp EX90 with 310 miles of all-electric range will be near the top of the shopping list.
HONORABLE MENTIONS
Less Model Y, more Kia EV6
If half the fun of driving a Model Y is terrifying your passengers with its straight-line speed, then the Kia EV6 has to be a serious contender for a replacement.
The sporty EV6 GT made its global debut by drag racing some of the fastest ICE-powered cars of the day, including a Lamborghini, Mercedes-AMG GT, a Porsche, even a turbocharged Ferrari – and it beat the pants off ’em. Combine supercar-baiting speed with an accessible price tag, NACS accessibility, $10,000 in customer cash on remaining 2024 models ($3,000 on 2025s) and just a hint of Lancia Stratos in the styling, the EV6 is tough to beat.
HONORABLE MENTIONS
Less Cybertruck, more therapy
It’s not bulletproof, it’s not easy to upfit, it shouldn’t be used for towing, and it won’t win in a straight fight against a vinyl picket fence. By just about every standard “truck” metric, the Tesla Cybertruck falls short against the competition from Chevrolet, Ford, and Rivian. On a more subjective front, the Cybertruck has become a symbol for a conservative movement that is (depending on your point of view) either making America great again or plunging a once-great democracy into an era of fascist oligarchy and widespread stupidity.
In short, it’s probably best to skip the CT.
If you disagree with that statement and feel like driving a new Tesla Cybertruck is the key to happiness, I’m not sure an equally ostentatious GMC Hummer EV or more subtle Rivian R1T will help you scratch that particular itch – but maybe therapy might!

Republicans launched multiple attacks against EVs, clean air and American jobs this week, at the behest of the oil industry that funds them. These attacks won’t be successful, and EVs will continue to grow regardless, and inevitably take over for outdated gasoline vehicles.
However, these republican attacks on EVs will still have some effect: they will diminish the US auto industry globally, leading to job losses and surrendering one of the jewels in the crown of American industry to China, where there is no similar effort to destroy its own domestic EV industry.
Republican attacks on clean air this week included moves to block funding that has led to a renaissance in US manufacturing and also to illegally block clean air laws. They also moved forward with a procedural step towards increasing US fuel costs by $23B, an effort which the former reality TV contestant posing as the head of the DOT announced in January.
These moves shouldn’t be a big surprise – republicans have opposed clean air and American jobs for many years now, and they’re doing it because they want to maintain the bribes they get from the oil industry.
But they should inspire worry for Americans, because they will only harm the country’s domestic manufacturing base in the face of a changing auto industry.
Republicans keep trying to kill clean cars
The last time a republican occupied the the White House, we saw similar efforts to try to raise fuel and health costs for Americans, and to block superior EV technology from flourishing. That didn’t work in the end, and EVs continued to grow both during that period and after.
All the while, fossil fuels have maintained their privileged policy position, being allowed to pollute with impunity and costing the US $760 billion per year in externalized costs. Much of that subsidy is accounted for in the cost of pollution from gas cars, which are one of the primary uses of fossil fuels, which means that, in fact, gasoline vehicles receive much more subsidy than EVs do.
And yet, EVs still managed to grow substantially, despite these headwinds. EV sales have continued to grow, both in the US and globally, even as headlines incorrectly say otherwise. The republican party’s attempts to kill them were futile, and will continue to be.
It didn’t work, but it did delay progress
However, anti-EV actions from Mr. Trump and the republican party did manage to delay progress from where it could have been if America actually instituted smart industrial policy earlier.
What if, instead of the bumbling, idiotic nonsense we went through the last time Mr. Trump squatted in the White House, we could have had something more like President Biden’s EV policy, which created hundreds of thousands of jobs and attracted hundreds of billions of dollars of manufacturing investment?
Surely the American auto industry would be ahead of where it is now if those investments had had time to come online. But instead, republicans are currently trying to kill those jobs, which has already led to several manufacturing projects being cancelled this year, depriving Americans of the economic boost they need right now.
Meanwhile, there’s one place that this sort of stumbling isn’t happening: China.
China is taking advantage
China has spent more than a decade focusing on securing material supply, building refining capacity, developing their own battery technology, and encouraging local EV manufacturing startups.
This has paid off recently, as Chinese EVs have been rapidly scaling in production in recent years. It took a lot of the auto industry by surprise how rapidly Chinese companies have scaled, and how rapidly Chinese consumers have adopted them, after having an initially slow start.
But that adoption hasn’t just been local, it’s also global. Last year, China became the largest auto exporter in the world, taking a crown that Japan had held for decades. But the change was even more dramatic than that – as recently as 2020, China was the sixth-largest auto exporter in the world, just behind the US in 5th place.
China’s dramatic turn upward started in 2020, and now it’s in first place. Meanwhile, because of all the faffing about, the US remains exactly where it was in 2020 – still in fifth place. Well, sixth now, since China eclipsed us (and everyone else).
Tariffs won’t fix it
The reaction of the rest of the world’s automaking countries has been to put tariffs on Chinese autos, hoping to forestall the country’s dramatic rise to dominance. (Although, due to Mr. Trump’s idiotic flailing, Europe is already talking about removing these trade barriers with China)
But tariffs have been tried before, and they didn’t work. When Japan had a similarly meteoric rise to global prominence as an auto manufacturer in the 1970s and 80s, largely due to their adoption of new technology, processes, and different car styles which incumbents were ignoring, the US tried to stop it with tariffs.
All this did was make US manufacturers complacent, and Japan still managed to seize and maintain the crown of top auto exporter (occasionally trading places with Germany) from then until now.
Then as now, the true way to compete is to adapt to the changing automotive industry and take EVs seriously, rather than giving the auto industry excuses to be complacent. But instead, republicans aren’t doing that, and in fact are working to ensure the American auto industry doesn’t adapt, by actively killing the incentives that were leading to a boom in domestic manufacturing investment.
US auto industry jeopardized by republicans
Make no mistake about it: destroying EV incentives, and allowing companies to pollute more and innovate less, will not help the US auto industry catch up with a fast moving competitor.
As we at Electrek have said for years, you cannot catch up to a competitor that is both ahead of you and moving faster than you.
This applies to individual companies, which took their sweet time responding to the challenge from electric upstarts like Tesla, and have now lost market share to said upstarts and let a competitor establish itself in a big way (even though Tesla’s CEO is now trying desperately to harm his own company specifically, and the US EV industry as a whole, by being the largest funder of the party working to destroy said industry).
It also applies to nations, which could have spent the last decade doing what the Chinese auto industry has been doing, but instead non-Chinese automakers have been begging their governments for more time, even though it’s not the regulations that threaten them, it’s competition from a new and motivated rival that is moving faster and in a more determined manner towards the future.
The way that we get around this should be clear: take EVs seriously.
But that’s not what republicans are doing, and in doing so, they are signing the death warrant for an important US industry in the long term.
Another thing republicans are trying to kill is the the rooftop solar credit, which means you could have only until the end of this year to install rooftop solar on your home before the cost of doing so goes up by an average of ~$10,000. So if you want to go solar, get started now, because these things take time and the system needs to be active before you file for the credit.

International equipment manufacturer Vermeer has unveiled a full-scale prototype of its Interlune excavator, a machine designed to ingest 100 metric tons of rocks and dirt per hour, extracting valuable helium as it makes its way across the surface … of the Moon.
Helium plays a critical role in the manufacturing of semiconductors, chips, optics, and all the other stuff that makes EVs, autonomy, the Internet, and the rest of twenty-first century life possible. The problem is that, despite being the second-most common element in the universe, helium is pretty rare on Earth – and we are rapidly running out. As such, there are intense economic and political pressures to find new and reliable sources of helium somewhere, anywhere else, and that demand has sparked a new modern space race focused on harvesting helium on the Moon and getting it back home.
To that end, companies like American lunar mining startup Interlune and the Iowa-based equipment experts at Vermeer are partnering on the development of suite of interplanetary equipment assets capable of digging up lunar materials like rocks and sand from up to three meters below the surface, extract helium-3 (a light, stable isotope of helium believed to exist in abundance on the Moon), then package it, contain it, and ship it back to Earth.
“When you’re operating equipment on the Moon, reliability and performance standards are at a new level,” says Rob Meyerson, Interlune CEO. “Vermeer has a legacy of innovation and excellence that started more than 75 years ago, which makes them the ideal partner for Interlune.”
Enter: Japan
America isn’t the only spacefaring nation eyeing a helium mine on the Moon. Japan announced similar plans back in 2023, with Japanese construction giant Komatsu announcing plans to develop a fully electric excavator capable of operating on the lunar surface.
The company showed a scaled prototype of the machine at the 2025 Consumer Electronics Show (CES) in Las Vegas (above), emphasizing the need to develop new ways to operate equipment assets in the extreme temperatures of extraplanetary environments beyond diesel or even hydrogen combustion.
On the airless surface of the moon, it would be impossible for an internal combustion engine to operate on the moon’s surface because there is no oxygen for combustion. Electrically powered machines seem the obvious solution with solar power generation supplying the electricity. But the answer is not that simple.
Temperature changes on the surface of the moon are extreme. They can soar to 110° C and plummet to -170° C. Developing electric construction machinery to perform in this environment is no easy task, but Komatsu is tackling issues one by one as they appear. Using thermal control and other electrification technologies, we are engineering solutions.
Despite Komatsu’s apparent head start, however, Vermeer seem to pulled ahead – not just in terms of machine development, but in terms of extraction potential as well.
“The high-rate excavation needed to harvest helium-3 from the Moon in large quantities has never been attempted before, let alone with high efficiency,” said Gary Lai, Interlune co-founder and CTO. “Vermeer’s response to such an ambitious assignment was to move fast. We’ve been very pleased with the results of the test program to date and look forward to the next phase of development.”
Interlune is funded by grants from the US Department of Energy and NASA TechFlights. In 2023, the company received a National Science Foundation (NSF) Small Business Innovation Research award to develop the technology to size and sort lunar regolith (read: dirt). Interlune has raised $18 million in funding so far, and is planning its first mission to the Moon before 2030.
Electrek’s Take
We’ve got space travel, weird mineral extraction from another planet that’s essential for our technology, and a rapid, unchecked proliferation of AI. All we need now is big worms, a whole bunch of hallucinogenic narcotics, and the will to smash up a bunch of data centers with baseball bats – then we’ll have a pretty decent Dune LARP going. Yee-ha!
