Nuclear fusion just passed a major milestone: Generating more energy than used to create the reaction
The National Ignition Facility target chamber at the Lawrence Livermore National Laboratory is where scientists shoot lasers and watch and measure what happens when those lasers collide on a fuel source. Temperatures of 100 million degrees and pressures extreme enough to compress a target up to 100 times the density of lead are created in this facility.

On Tuesday, the head of the Department of Energy and other federal scientific leaders announced that a fusion reaction run at the Lawrence Livermore National Laboratory in California achieved net energy, meaning the reaction generated more energy than was put in to initiate the reaction. It is the first time humankind has achieved this landmark.
Fusion is the way that the sun makes power, but recreating a useful fusion reaction here on earth has eluded scientists for decades. Achieving net positive energy paves the way for fusion to move from a lab science to a usable energy source.
Fusion is particularly attractive given the increasing urgency of climate change because it produces no carbon emissions, nor does it produce the long-lasting nuclear waste associated with nuclear fission, which is the type of nuclear energy used today.
The event happened on Dec. 5, the Lawrence Livermore National Laboratory said on its Twitter account on Tuesday. “On December 5, 2022 a team from DOE’s @Livermore_Lab made history by achieving fusion ignition.” it wrote. “Also known as scientific energy breakeven, the experiment produced more energy from fusion than the laser energy used to drive it.”
“This is important. Earlier results were records, but not yet producing more energy out than was put in,” Andrew Holland, the CEO of the industry’s trade group, the Fusion Industry Association, told CNBC. “For the first time on Earth, scientists have confirmed a fusion energy experiment released more power than it takes to initiate, proving the physical basis for fusion energy. This will lead fusion to be a safe and sustainable energy source in the near future.”
One step toward the ‘holy grail’ of clean energy
Speculation swirled in the days leading up to the press conference because the interest in fusion as a potential viable energy source has increased dramatically in recent years as concerns about climate change and energy security have become more acute.
More than 90 nuclear power reactors currently operate in the United States, but those nuclear reactors are making energy with nuclear fission, which is when a neutron smashes into a larger atom, causing it to split into two smaller atoms and releasing a lot of energy. Nuclear fission reactions do not release any carbon dioxide emissions and there for are considered clean energy, according to the U.S. Department of Energy.
The United States got approximately 19 percent of its utility-scale electricity generation from those nuclear power plants in 2021, according to the U.S. Energy Information Administration, and the energy from nuclear fission reactors represents half of the clean power generated in the United States, according to the Department of Energy.
However, those reactors generate long-lasting nuclear radioactive waste when they operate, and most countries, including the United States, currently have that nuclear waste sitting on dry cask barrels on nuclear reactor sites all over the country. Efforts to build a permanent, underground geologic storage for nuclear fission waste have thus far been stymied in the United States.
Fusion happens when two atoms slam together to form a heavier atom, releasing huge amounts of energy without generating carbon dioxide emissions or long-lasting nuclear waste. But it’s proven extremely challenging to sustain a fusion reaction here on earth, and scientists have been chasing trying for decades. In particular, it requires massive amounts of energy to generate fusion on reactions, and until this experiment, nobody had demonstrated the ability to get more energy out of the reaction than it takes to power it.
“Scientists have struggled to show that fusion can release more energy out than is put in since the 1950s,” plasma physicist Arthur Turrell told CNBC.
“During those decades, every time anyone has asked for funding for developing fusion power, the response has always been ‘first, you must show that it works in principle,'” Turrell said. “That is, you must show that a fusion experiment can produce more energy than it uses. The researchers at Lawrence Livermore have done this for the first time ever.”
The success could also spur more private investment in fusion, which is already a hot space –so far, investors have poured almost $5 billion in investment into private fusion energy startups, according to the Fusion Industry Association, and more than half of that has been since since the second quarter of 2021.
“Everyone in the laser fusion (or inertial confinement fusion) community has been focused on getting to more energy out than in on a single experiment, because that is the key to showing the proof of principle and unlocking further investment and interest,” Turrell told CNBC.
Indeed, the private fusion industry is seeing this as a win.
“Now, the privately funded fusion industry will take the next steps, turning experimental results like this into a viable source of clean, safe energy,” Holland told CNBC. “In short, this will show the world that fusion is not science fiction: it will soon be a viable source of energy. Of course there are still many steps between these experimental results and fusion power plants, but this is an important milestone that brings us closer to the day when fusion will provide the world with clean, safe, and abundant energy.”
Rivian has posted a job listing for a steering engineer, specifically mentioning work on a future steer-by-wire system for the company.
Update, Aug 11: Rivian has now specifically mentioned rear-wheel steering in a job posting.
Steer-by-wire is an automotive concept that has been around for a long time, but hasn’t yet reached mass adoption. The idea is to replace (or supplement) mechanical linkages between the steering wheel and the wheels with electronic actuators instead.
There are a number of potential benefits to this, like allowing more customizability or adaptability to a steering system, reducing mechanical complexity, or adding speed-sensitive variable steering ratios.
Although there are also disadvantages, like a reduction in steering feel (although, since most cars are moving to electronic power steering, that was already gone anyway).
But few cars have implemented steer-by-wire systems, or at least not fully committed to them, given that mechanical steering racks are a relatively solved problem and the general inertia of the car industry which would rather stick with a solution they know than switch to something better (haven’t we here, at this EV publication, heard *that* one before…). There’s also the matter of regulations, which have often been written to require mechanical steering systems, and may need updating to allow for steer by wire.
But, steer by wire made it into mass production with the release of the Tesla Cybertruck. This was big news when Tesla committed to this – at the time, it was the only thing on the road to exclusively use a steer by wire system, though there are other cars with partial steer by wire (for example, mechanical front wheel steering, and steer by wire rear-wheel steering).
But it seems to have opened the floodgates, as a number of other companies are working on or have since released steer by wire systems (Lexus, for example).
And now, it looks like Rivian is one of those companies – though we don’t know if it’s for the front or rear. (Update: Well, now we know, it looks like they are at the very least developing a rear-wheel steering system, according to another job listing. Though the company might still be working on steer-by-wire for the whole vehicle, too)
The company posted a job listing for “Sr. Staff Technical Program Manager, Steering Actuator System,” based at its Irvine, CA headquarters (spotted by Rivianforums). This wouldn’t be so exceptional, except that the job posting also specifically points out that “you’ll have full cradle-to-grave ownership of the SBW subsystem.”
So – we know they’re working on steer by wire, to some extent.
But a few other EVs, particularly large EVs like the Rivian R1 platform is, use steer by wire just for the rear wheels – for example the Hummer EV and Rolls-Royce Spectre. These systems are particularly helpful for giant vehicles, because it allows them to be more nimble and make turns that otherwise would require a lot more… negotiation in a giant land yacht.
So it’s possible that Rivian is only working on rear wheel steer by wire here, but we’d like to think there’s a chance it’s working on steer by wire for the full vehicle.
We also don’t know if this would show up on all of Rivian’s vehicles, or only on certain models – the R2 and R3 are in development, with R2 in pretty late stages, and the R1 just got a big refresh. But, perhaps even more interestingly (and very speculatively), VW has invested heavily in Rivian for technology help, so we wonder if we might end up seeing this in VW group vehicles, or Scout vehicles eventually…

Automakers are scrambling to push their EVs out the door before the $7,500 Federal tax incentive for EVs disappears — and BMW is no different, offering aggressive cash back, owner loyalty, and special financing rates on its just-released 2026 model year EVs.
BMW has a history of offering solid loyalty incentive programs on its EVs in early summer to clear the tail-end of the model year and make room for the incoming builds, but CarsDirect is reporting some unusual loyalty deals from the brand that seem to suggest BMW is keen to capitalize on a spike in EV sales ahead of the Federal tax incentive’s looming cancellation in September.
BMW dealers now have the choice of adding an additional $1,000 loyalty contribution on select 2026 EVs. The i5 and i7 are offered with $1,000 and $4,000 loyalty bonuses, respectively, meaning if you drive a BMW and your dealer opts to tack on the extra bonus, you could save $5,000 on a 2026 i7. These loyalty programs are good when buying or leasing.
There’s also a $1,000 conquest bonus available for drivers of eligible EVs and PHEVs from other brands. This program is stackable with other offers.
Like other EV brands offering huge lease incentives, BMW customers will see the largest rebates on new BMWs when leasing. Now through September 30th, 2026 BMW i5, i7, and iX models are available with a stout $9,900 lease credit, while the bigger BMW XM comes in with a slightly lower, but still substantial $7,500 lease incentive.
Big deals on big BMW i7 sedan
People who prefer to own their vehicles once the payments are up can still score a great deal on an objectively excellent 2026 BMW i7 luxo-cruiser, thanks to the previously mentioned loyalty bonus if they’re previous customers plus a $7,500 Loan Credit that anyone can get when financing their new i7 with the brand’s captive financing company. BMW Bank offers financing rates as low a 3.99% for up to 60 months on the 2026 i5 and i7 sedans, as well as the iX crossover, as well as 4.99% APR 60-month rate on the high-performance XM plug-in hybrid.
The BMW iX, of course, snatched the top spot in J.D. Power’s EV Satisfaction Survey last year, having taken the crown from its BMW i4 stablemate. You can find out what’s behind that score here, or experience it for yourself at a local BMW dealer near you.

This week, industrial real estate giant Prologis flipped the switch on a rooftop solar project at one of its Franklin Park, Illinois warehouses — the first of 45 such rooftop installations the company plans to deploy in the next two years. Once finished, Prologis’ community solar project will generate up to 82 MW of clean energy!
Co-developed with Illinois utility ComEd and SunVest Solar, the independent power producer, the new rooftop community solar installation in Franklin Park sits atop a 195,000 sq. ft. Prologis logistics center serving a number of local and regional businesses.
Prologis will own and operate the 1.56 MW community solar project, and the energy it generates will serve mostly residential customers, with the minority of the community solar credits created benefiting local businesses.
“We’re proud to join ComEd to officially launch this project, the first of many community solar projects that our energy team is deploying across our Illinois rooftops,” explains Carter Andrus, Prologis’ Chief Operating Officer. “Illinois is one of the fastest-growing solar markets in the country, and we’re excited to help lead its momentum. For us, this is about more than solar panels … it’s about using our scale to make a real difference in the communities where we operate and bring the benefits of clean energy to more people across Illinois.”
Collaborative effort
Prologis is deeply invested in a number of distributer energy resources (DER), including rooftop solar, battery energy storage, and OnDemand Power, a scalable, portable microgrid and power management solution (read: software) designed to provide resilient, backup, and dispatchable energy where and when it is needed across the company’s global portfolio.
“As we continue to support the expansion of solar across northern Illinois, new and planned Prologis rooftop solar sites promise to provide northern Illinois customers additional options for lowering their energy costs via renewable energy connected to the grid,” offers Gil Quiniones, President and CEO of ComEd. “With dozens of additional projects in the pipeline, we are seeing the effect of the pro-solar incentives put in place by Governor JB Pritzker’s administration and how they support a cleaner, more equitable energy future in our state.”
With nearly 800 MWs of rooftop solar and energy storage already deployed and 82 more coming from Northern Illinois alone, Prologis is on track to reach its goal of 1 gigawatt by end of 2025. (!)
