Bill Gates and Warren Buffett want to build a new kind of nuclear reactor to generate electricity. Why? Because the wind doesn’t always blow and the sun doesn’t always shine. They intend to plunk their new toy down in the state of Wyoming on the former site of a coal-fired generating plant.
“This is our fastest and clearest course to becoming carbon negative,” says Wyoming’s governor Mark Gordon. “Nuclear power is clearly a part of my all-of-the-above strategy for energy.” Wyoming is the top coal producing state in America.
According to The Guardian, the new facility will be a joint venture between TerraPower, founded by Gates 15 years ago, and PacifiCorp, a Berkshire Hathaway-owned utility that serves customers in Wyoming, Idaho, Utah, California, Oregon, and Washington.
Small advanced reactors, which run on different fuels than traditional reactors, are regarded by some as a critical carbon-free technology that can supplement intermittent power sources like wind and solar as states strive to cut emissions that cause climate change. “We think Natrium will be a game-changer for the energy industry,” Gates told a media conference in Cheyenne, Wyoming this week.
The Guardian says the new generating station will produce 345 megawatts of electricity, but the output can be boosted by a molten salt energy storage component to 500 megawatts. The primary feature of the so-called Natrium technology is that it uses sodium to cool the reactor instead of water. Natrium is the Latin word for sodium, which is why its symbol on the periodic table of elements is Na.
Chris Levesque, TerraPower CEO, told the press this week the demonstration plant will cost about $1 billion and will take about seven years to build. “We need this kind of clean energy on the grid in the 2030s,” he told reporters. Actually, Chris, we need clean energy on the grid now, not 7+ years from now. A billion dollars would buy more than 500 MW of power and have it online, together with grid storage batteries, in a lot less time. Why wait?
Natrium Technology
I am not a nuclear engineer nor am I a rocket scientist, so I have to rely on Wikipedia to inform me about some things (I contribute $5 a month to support Wikipedia and encourage you to do the same).
The primary advantage of liquid metal coolants, such as liquid sodium, is that metal atoms are weak neutron moderators. Water is a much stronger neutron moderator because the hydrogen atoms found in water are much lighter than metal atoms, and therefore neutrons lose more energy in collisions with hydrogen atoms.
This makes it difficult to use water as a coolant for a fast reactor because the water tends to slow (moderate) the fast neutrons into thermal neutrons (though concepts for reduced moderation water reactors exist).
Another advantage of liquid sodium coolant is that sodium melts at 371K and boils / vaporizes at 1156K, a total temperature range of 785K between solid / frozen and gas / vapor states. By comparison, the liquid temperature range of water (between ice and gas) is just 100K at normal, sea-level atmospheric pressure conditions. Despite sodium’s low specific heat (as compared to water), this enables the absorption of significant heat in the liquid phase, even allowing for safety margins. Moreover, the high thermal conductivity of sodium effectively creates a reservoir of heat capacity which provides thermal inertia against overheating.
Sodium also need not be pressurized since its boiling point is much higher than the reactor’s operating temperature, and sodium does not corrode steel reactor parts.[2] The high temperatures reached by the coolant (the Phénix reactor outlet temperature was 560° C) permit a higher thermodynamic efficiency than in water-cooled reactors. The molten sodium, being electrically conductive, can also be pumped by electromagnetic pumps.
Disadvantages
A disadvantage of sodium is its chemical reactivity, which requires special precautions to prevent and suppress fires. If sodium comes into contact with water it reacts to produce sodium hydroxide and hydrogen, and the hydrogen burns when in contact with air.
This was the case at the Monju Nuclear Power Plant in a 1995 accident. In addition, neutron capture causes it to become radioactive; however, activated sodium has a half-life of only 15 hours. Another problem is sodium leaks which are regarded by a critic of fast reactors, M.V. Ramana, as “pretty much impossible to prevent.”
Fuel Used
Wikipedia adds that a natrium facility that generates less than 500 MW of electricity uses “uranium-plutonium-minor-actinide-zirconium metal alloy fuel, which is supported by a fuel cycle based on pyrometallurgical reprocessing in facilities integrated with the reactor.” I don’t know about you, but the words “uranium” and “plutonium” don’t sound like “different fuels compared to traditional nuclear reactors.”
The Guardian points out that nuclear power experts have warned that advanced reactors could have higher risks than conventional ones. Fuel for many advanced reactors would have to be enriched at a much higher rate than conventional fuel, meaning the fuel supply chain could be an attractive target for militants looking to create a crude nuclear weapon. And don’t even be concerned about Russian hackers. We know those malefactors only like to interrupt gasoline pipelines and beef processing plants. Pooty Poot and his henchmen would never stoop so low as to hack a nuclear power plant…would they?
People always rush to criticize Tesla for selling emissions credits, but no one wants to talk about the $80 million the US Department of Energy has already invested in TerraPower with millions more coming in the future. No one would expect Bill Gates and Warren Buffett — two of the richest white men in history — to foot the bill for their boondoggles all by themselves, would they?
All Of The Above
The key to understanding this story is found in Governor Gordon’s use of the words “all of the above.” That’s free market speak for “We’re happy to have a piddly little 350 MW facility of over here, just so long as we can continue supporting coal- and gas-powered generating plants that churn out hundreds of gigawatts over there.” In other words, it’s a smokescreen designed to allow fossil fuel interests to kick the can down the road a little further and add some greenwashing to their corporate portfolios at the same time.
Being rich does not necessarily make a person all that smart. America needs more nuclear power like a fish needs a bicycle. People in Wyoming may be fooled by this blather, but CleanTechnica readers aren’t taking the bait. Natrium was probably selected as the name of thus new nuclear technology because it sounds a little like “nature” or “natural.” That’s a great marketing ploy, but we’re not buying it. Frankly, the Bill and Warren show is more than a little disappointing.
Even without clean fleet tax credits and cash-on-the-hood incentives, fleet managers are working hard to maximize their ROI on vehicle assets and reduce their total cost of ownership – and they’re increasingly turning to data‑driven telematics solutions to help.
Telematics use data gathered from sensors embedded in a vehicle to monitor its operations. When collected and interpreted correctly, that data can be used to improve fleet safety, boost operational efficiency, and enable predictive maintenance that reduces (if not eliminates) unexpected downtime. Those are real benefits, with some analysts showing up to 30% savings in repair costs even before you factor in the fuel savings from EVs that, according to MAN CEO Alexander Vlaskamp, will cover the added cost of a BEV in less than three years.
We originally covered these topics back in February, ahead of the ACT Expo. You can read that original article, below, and let us know what you think of the OEMs’ telematics’

Last month, Geotab signed a deal with Volvo Group to integrate the manufacturer’s vehicle data API into Geotab’s telematics platform. It’s the latest in a recent onslaught of such deals between telematics providers and OEMs that begs the question: what’s in it for the OEMs?
“Smart tools informed by data like E-Switch Assist are opening up many new conversations with our commercial customers large and small about EV readiness; we’re already using E-Switch Assist regularly in consultations to help organizations determine if electric trucks and vans are right for them,” says Nate McDonald, EV strategy and cross vehicle brand manager at Ford Pro. “The importance of these tools and technologies goes beyond selling a customer a new vehicle—it changes mindsets about whether electric vehicles will work for their business while potentially saving them time and money.”
So, it makes sense for manufacturers to build that connectivity into their vehicles and makes even more sense to use that data connection to populate a fleet management dashboard that makes it painless for fleet managers to monitor their assets within a trusted ecosystem. Think Android vs. iPhone, and the pain that would go into switching from one to the other after a decade or so of constant interaction – because that’s how the OEMs are looking at it.
Why, then, would an OEM open up that data stream to a third party like Geotab?
The answer, presumably, is that that data sharing is a two-way street: the manufacturer’s are opening up their APIs to Geotab, and Geotab is sharing at least some of the data from other manufacturers with their industry partners.
And Geotab has a lot of partners:
In 2019, Geotab began working with Ford to integrate Ford’s telematics data into its fleet management platform
In 2022, Geotab began partnering with Stellantis’ Free2move car sharing brand, providing full telematics integration into the MyGeotab platform in North America
In April of 2024, Geotab partnered with Mobilisights to integrate data from Stellantis’ European brands, including Opel, Fiat, Alfa Romeo, Citroën, and Peugeot
In September of 2024, Geotab announced a new partnership with VW Group Info Services aimed at improving the company’s data integration across its brands
All of those players are convinced that the data coming from their vehicles can produce enough value to seriously impact fleet ROI.
Fleet managers seem convinced, too. In a recent McKinsey survey, nearly 57% of EV buyers said they were willing to switch brands in order to get better connectivity features. And, if you’ve ever worked in “a Ford shop” or “a Chevy shop” you already know what a huge that deal that number might be to an OEM.

In that point of view, working with a trusted, universal platform like Geotab who doesn’t have a dog in the vehicle sales fight makes sense. If the Ford Transit the fleet buyer is looking at plays well with their fleet auditing software and systems and the Nissan NV doesn’t – well, it doesn’t really matter if Nissan’s fleetail guy is giving you a better deal at that point. It’s just too painful to operate a second dashboard for one subset of assets.
The man-hours saved with a universal and brand agnostic fleet management platform may not be the easiest to trace all the way to the bottom line, but they’re there.
Geotab research shows that EV batteries could last 20 years or more if they degrade at an average rate of 1.8% per year, as we have observed.
According to our data, the simple answer is that the vast majority of batteries will outlast the usable life of the vehicle and will never need to be replaced. If an average EV battery degrades at 1.8% per year, it will still have over 80% state of health after 12 years, generally beyond the usual life of a fleet vehicle.
Telematics integrations can also help optimize a fleet’s charging schedules, both by scheduling EV charging for lower priced, off-peak hours and by identifying the most dependable high-speed charging stations along regular routes to minimize down time for both vehicles and drivers.

Geely-backed performance EV brand Polestar has had some troubling times in recent months, but its future is looking a whole lot better after the company secured a $600 million loan facility to help it keep on keepin’ on.
In a vote of broader confidence and better times ahead, Volvo’s parent company Geely Sweden Holdings AB is backing the brand with more than half a billion dollars of fresh funding to extend its operational runway:
Polestar, as borrower, entered into a credit agreement with a wholly owned subsidiary, as lender, of Geely Sweden Holdings AB in relation to a subordinated term loan facility of up to USD 600 million, of which the last USD 300 million would require lender consent based on Polestar’s future liquidity needs. The term loan facility is available to Polestar for general corporate purposes.
The company has four models in its current line-up on sale in 28 countries, along with additional planned models that include the Polestar 7 SUV (set to be introduced in 2028) and the Polestar 6 coupe/roadster.
Electrek’s Take

Product-wise, at least, it’s hard to argue that Polestar’s future appears to be anything but bright. The new Polestar 3 crossover is a viable competitor to the industry-leading Tesla Model Y, and the upcoming Polestar 4 and 5 models seem like winners, too. To drive that point home, Polestar is promoting up to $18,000 in incentives to lure in Tesla buyers.

Whether it’s to keep the lights on after a natural disaster or just to avoid peak energy rates, more people than ever are adding battery energy storage to their home solar systems — but li-ion batteries aren’t the only option. The new WATT Fuel Cell uses the natural gas connection your home already has to generate power when you need it.
Technically a solid oxide fuel cell, the WATT unit turns the natural gas in your home into electricity without combustion, relying instead on a chemical reaction between the natural gas and oxygen in the air to create an electric current in a way that’s conceptually similar to a hydrogen fuel cell, but that makes use of a more readily available (and far cheaper) fuel source to generate power while producing far fewer harmful emissions than a conventional generator.
How it works
By WATT Fuel Cell.
The company’s latest offering, the WATT HOME system, recently achieved certification at a 2 kW power rating, marking an important step on the company’s commercialization roadmap as it races to meet market demands for a natural-gas-powered backup solution to guarantee uptime in outage-prone regions.
This week, the company marked another major milestone by installing the of its first 2 kW WATT HOME solid oxide fuel cells (SOFC) at the Edward M. Smith National Career and Life Skills Development Center, Hope Gas’ new state-of-the-art training facility in Clarksburg, West Virginia – but the news doesn’t end there.
“The WATT HOME system’s new 2 kW certification … validates the performance capabilities we’ve engineered for years and strengthens our competitive position as we move into multi-year deployment with Hope Gas,” says Caine Finnerty, WATT’s CEO and Founder. “With the ITC benefit, we anticipate accelerated adoption and substantial value for customers, utilities, and investors.”
The gas fuel cell can send power directly to the home’s panel, keeping the lights on directly, or perform the same function as a solar panel, sending power to a battery where it can be stored for later use.
Keep in mind, though – this isn’t a zero emissions option the way a solar + battery solution is. This is very much a fossil fuel-powered solution that gives off carbon and nitrous emissions, and the only reasons we’re talking about it are:
the tech is kind of cool
I didn’t know these existed
it is objectively cleaner than a conventional ICE generator
That said, while solar is still the better solution in an ideal world, a WATT HOME fuel cell might be a better option in situations where rooftop space is limited (or nonexistent), such as condos or vertically-designed townhomes. In those scenarios, solar panels are unlikely to generate a meaningful amount of electricity, but a fuel cell that can tap into the buildings’ existing natural gas lines to provide reliable backup power if the grid fails.
That makes the fuel cell an attractive option for residents in multi-unit buildings, older historic neighborhoods with strict aesthetic rules, or any building where adding solar panels aren’t feasible, but a low-emission, low-noise backup solution is still needed.
The better question, then, isn’t is it better than solar – it’s is it better than solar for you? If you’re in West Virginia, you might be able to find out in just a few weeks. In the meantime, watch WATT’s own explainer video, below, then let us know what you think of the idea of a natural gas fuel cell in the comments.
