Bill Gates & Warren Buffett To Build A New Kind Of Nuclear Reactor — Is That Good News?
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.

345 Megawatts
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).
Here is what I found out:

Advantages
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.
A recent AAA poll shows that just 13% of Americans trust self-driving cars, leaving 87% either unsure about, or “too afraid” to give up the controls. At the same time, it seems like Stellantis is giving up on its highly-publicized AutoDrive Level 3 ADAS.
Is this the beginning of the end of self-driving hype?
Reuters is reporting that several inside sources have Stellantis shelving its STLA AutoDrive Level 3 ADAS program over of high costs, technological challenges, and – crucially – ongoing concerns about consumer trust in self-driving technology.
A 2025 survey from AAA indicates that more than 60% of American drivers are “afraid” to ride in a self-driving car, while only 13% think the development of self-driving technology should be a priority – but what might be more disturbing for companies that are deeply invested in autonomy is that the public’s attitudes don’t seem to be improving.
In fact, the percentage of people afraid of self-driving has actually grown from 2021 to ’25, rising from 54% to 61% over the last few years.
“Most drivers want automakers to focus on advanced safety technology,” explains AAA automotive engineering director Greg Brannon. “Though opinions on fully self-driving cars vary widely, it’s evident that today’s drivers value features that enhance their safety.”
Given that, it’s no wonder Stellantis is backing off – but not giving up. “(STLA AutoDrive) was unveiled in February 2025 was L3 technology for which there is currently limited market demand,” a Stellantis spokesperson told Reuters. “So this has not been launched, but the technology is available and ready to be deployed.”
When asked how much time and money was spent on AutoDrive, Stellantis declined to say.
Electrek’s Take
When you’re busy doubling down on self-driving technology while lying about the tech’s capabilities and fending off ten-figure lawsuits – well, let’s just say that the optics are not good. Here’s hoping Elon doesn’t spend all that bonus he got (he might need it).

Alexander Vlaskamp, the outspoken CEO of MAN Trucks, claims that an electric semi truck can pay for itself in less than three years – but there are a few asterisks in that statement. We’ll try to unpack them all for you here.
MAN began series production of its eTruck electric semi in July on a flexible line capable of building up to 100 trucks per day with either diesel or battery-electric power. With production underway, the challenge now is selling the things. That means proving that the higher upfront cost pays off with a lower total cost of ownership (TCO), and the first stop on that train is incentives.
The good news is that, in the EU, incentives are plentiful. MAN says those programs, together with Europe’s much higher diesel prices compared to the US (about $6.80/gal compared to $3.70, as I type this), can help the eTruck pay for itself in as little as two and a half years.
And, if you’re not familiar with European incentives for electric semi trucks, hold on to your hats because they are wild:
- up to 80% of vehicle purchase price subsidy in Austria (ENIN)
- in Belgium, there’s a subsidy for up to 32% of the price of the truck (up to 2 trucks per company)
- in Ireland, government incentives cover 30–60% of the up-front cost difference versus a comparable diesel truck
- Norway offers a similar 60% diesel cost difference incentive
- etc., etc., ad nauseam
MAN’s customers can do that math easily enough – the company says it already has 700 orders on the books already, and expects to hit 1,000 by year’s end. But that math only maths if those customers can actually access the electrons to replace all that diesel … and the charging infrastructure they’re going to need for all those trucks? That’s still a ways off.
“It’s all about the charging infrastructure, that’s the problem,” Vlaskamp told Börsen-Zeitung. “When it comes to investment in charging stations, Europe is lagging far behind … what’s needed now is the political will to reverse this trend,” adding, “We need to act quickly.”
Charging is key
Spanish-language site Motorpasión notes that red tape isn’t the only reason charging lags. Driving investment into new charging infrastructure is lagging, too – but MAN’s CEO thinks there’s a simple fix: take half of annual toll revenues generated by commercial trucks (around €7 billion in Germany, alone) and funnel it directly into DC fast charging.
In addition to the still deficient charging network, another obstacle is the cost of electricity for charging. Vlaskamp proposes a reduced price for commercial truckers, as has traditionally been the case with diesel. Currently, the average price is 45 to 50 cents per kWh, but says the ideal would be, “between €0.20 and €0.30/kWh.”
TL;DR: if charging was cheaper and easier to access and the government was willing to subsidize EVs as much as they’ve subsidized oil with the creating and ongoing support of a globalized military industrial complex, MAN Trucks’ CEO thinks plug-in semis would be a no-brainer.
Head on down to the comments and let us know if you agree.

It’s Labor Day weekend, which means big deals on car lots across America – especially if you’re shopping for a new electric vehicle to help with your labor. We’ve rounded up the best offers on electric pickups, vans, and even a great option for ride share drivers!
Sure, there’s a bit of irony in pitching “work vehicles” on a holiday meant for not working – but for many small business owners, work is part of who they are. And with the $7,500 federal EV tax credit set to expire, plus a wave of great Labor Day deals on work-ready EVs, now might be the best time yet to plug into a new electric ride.
Here are some of the standout electric vehicles offers we found this Labor Day weekend (2025), organized by vehicle type.
Electric pickup | F-150 Lightning
The “Ford for America,” summer sales event continues through Labor Day with interest-free 0% financing, $0 down payment, and zero payments for up to 90 days for retail customers. Ford is also throwing in $0 maintenance for 24 months.
But wait, there’s more! Ford Authority is reporting that a complimentary home charger and standard installation might also be included as part of the Ford Power Promise promotion happening at participating dealers in select markets with the purchase of a new F-150 Lightning pickup through the end of September.
Lease customers aren’t being left out, either. You can lease a 2025 Ford F-150 Lightning XLT 4P 311A pickup at $399 per month for 36 months, with “just” $399 due at signing (basically your first month’s payment).
Electric van | Chevy Brightdrop
The best electric vehicle deal in the business keeps on truckin’ into Labor Day weekend, with new 2025 Brightdrop models currently eligible for up to $21,500 in manufacturer rebates before any Federal, state, local utility, or even Costco membership incentives kick in.
For your money, you get a capable, Ultium-based electric cargo van with more room than your college dorm and a nationwide dealer network to keep it up and running when you need it most.
Electric van (hon. mention) | Mercedes eSprinter
Despite being based on the company’s existing diesel platform, Mercedes’ eSprinter has proven itself a capable urban hauler in the hands of Amazon, DHL, and countless European tradespeople. Despite that, there are still a handful of leftover 2024 models hanging around dealer lots – enough that Mercedes is offering up to $30,000 (!) Customer Cash on any new ’24MY eSprinter purchased from dealer stock.
That discount is enough to bring the price of this 2024 eSprinter in Chicago from $87,823 all the way down to $57,823 this Labor Day weekend – and that’s before you factor in state and local utility incentives that can bring the price down even further.
As you can imagine, there’s some fine print on that Customer Cash deal. It can’t be combined with Special APR programs through Mercedes-Benz Financial Services (MBFS), but it can be combined with the Mercedes-Benz Commercial Vehicles Medium Fleet Program.
Ride share ride | VW ID.4
Ride share drivers looking for comfortable seats, room for five adults and their luggage, proven battery life, and lickety-quick charging speeds can stop looking. Volkswagen is offering a sweet ID.4 lease at nearly half the cost of an entry-level Jetta with payments starting at just $129/mo. – that’s despite the ID.4 carrying a significantly higher MSRP.
And, while we’re at it, it’s probably worth noting that serious road warriors will probably save more than $129/mo. in fuel alone.
If you prefer to own your vehicles after making payments on them for a few years, you can also get 0% interest financing on select ID.4s for up to 72 months. It’s important to note here that Volkswagen’s deals can vary wildly by region. That $129/mo. offer is available in California and a few other West Coast states, for example, but the electric crossover’s listed at $329 for 24 months with $4,499 due at signing in others.
Disclaimer: the vehicle models and financing deals above were sourced from CarsDirect, CarEdge, and (where mentioned) the OEM websites – and were current as of 29AUG2025. These deals may not be available in every market, with every discount, or for every buyer (the standard “with approved credit” fine print should be considered implied). Check with your local dealer(s) for more information.
