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.
Africa received its first heavy-duty commercial electric truck this past week, a Volvo Trucks FE Electric garbage truck (waste collector). The electric garbage truck will be the first fully electric heavy-duty truck from a global manufacturer to begin operation in Africa, marking a significant milestone as we move closer toward a sustainable transportation industry globally.
Volvo Trucks is leading the charge toward a cleaner future with a broad lineup of zero-emission heavy-duty electric vehicles.
Founded in Sweden in 1927, Volvo Trucks has a rich history in the truck-making business. The company’s first truck rolled off the line in 1928, and Volvo has been leading the industry to new heights ever since with innovations, such as the three-point safety harness, the first fully integrated sleeper compartment, and unique designs to increase efficiency.
Seeing the progression to fully electric vehicles sooner than many of its counterparts, Volvo Trucks moved the industry forward again, releasing its first electric commercial truck, the FL Electric, in 2019.
Volvo followed it up, unveiling the Volvo VNR Electric featuring a larger battery designed to extend range.
In September, Volvo added three massive 44-ton heavy-duty EV trucks to its portfolio, bringing its total lineup to six, the most extensive in the industry, as it continues to add zero-emission options in different commercial categories.
The company’s trucks are helping companies go electric to reduce emissions and promote a zero-emission global transportation industry across the globe.
Volvo’s most recent electric truck was delivered to Africa. Volvo delivered its first heavy-duty truck to Morocco, a Volvo FE electric garbage truck, which is a big step for both the truck maker and Africa as they move closer to achieving their climate goals.

Volvo delivers first heavy electric garbage truck to Africa
In a press release, Volvo said it had delivered a series-produced zero-exhaust emission garbage truck to the city of Rabat in Morocco. Martin Nilsson, managing director of Volvo Trucks Morocco, said:
This clearly shows that zero-emissions trucks have a role to play in many parts of the world.
Volvo’s extensive heavy-duty EV lineup makes electrifying in all parts of the world possible. Arma, a Moroccan waste management company, will use the zero-emission truck to, well, collect waste, of course.
By replacing the existing diesel fleet with a Volvo FE electric during typical routes, Volvo says over 20 tons of CO2 could be saved annually.
The addition is part of Morocco’s unconditional climate goal of reducing emissions by 18.3% by 2030. Volvo is also aiming for 50% of all new vehicle sales to be electric by 2030.

Tesla is expanding its new sales strategy of using virtual sales advisers with remote test drive locations to Europe.
In the summer of 2021, Electrek exclusively reported that Tesla was implementing a new sales strategy. At the time, we reported that the main changes were that the automaker was moving away from high-rent locations in malls and shopping districts in favor of delivery centers and remote test drives.
The strategy is again focused on online sales, but Tesla has recognized that physical presence is still necessary to enable test drives.
When someone used to place an order for a Tesla vehicle online in North America, the customer was assigned a “Tesla Advisor” at their local store to help manage the process leading up to the delivery.
Instead, Tesla started to assign orders to “virtual sales advisors” not assigned to any specific stores, and customers could go to cheap remote test drive locations with Tesla vehicles in parking lots.
The company has been gradually implementing this new strategy in North America. Tesla has now expanded its strategy to Europe with its first remote test drive hub location in Sweden:
Tesla explains the simple process of using the location:
Book an appointment at http://tesla.com → call us when you’ve arrived → we remotely unlock the vehicle for you & walk you through the basics → test drive for 30 mins → drop off vehicle at the same location.
This enables Tesla to operate these locations with very few staff. The company simply needs to make sure those vehicles stay clean and charged.
When we first reported on the new strategy in 2021, sources told Electrek that Tesla was already seeing some success with the first few locations in the US.
Now that the company is expanding this strategy in Europe, we have to assume that the automaker is happy with it and has decided to implement it in new markets.
