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.
Aventon has officially announced its latest electric bicycle, the Pace 4, adding advanced smart bike technology and enhanced rider comfort to its popular line of urban-friendly e-bikes. The Pace 4 builds upon Aventon’s successful formula of accessibility and ease of use, now augmented with new connectivity and security features that make it harder to steal and easier to get back.
At the heart of the Pace 4 is Aventon’s latest innovation: the Aventon Control Unit (ACU). The ACU significantly upgrades the bike’s intelligence and security capabilities, bringing GPS tracking, geofencing, and remote locking to the Pace 4.
With the addition of the ACU, riders gain the ability to monitor their bike’s location in real-time, set virtual boundaries that trigger alerts if the bike leaves a specified area, and remotely lock the rear wheel, helping to improve security and peace of mind. A startup passcode can also be enabled to further improve theft deterrence, ensuring the bike can only be activated by authorized users.
The remote locking and passcode can help deter some theft, but the GPS tracking makes it easier to get the bike back if it ever does find itself in the wrong hands. The GPS feature and the 4G data communication both require a 4G data subscription, which is provided complimentary for one year at the time of purchase.
Of course, there’s no such thing as a theft-proof bicycle, but these types of smart features help riders get closer to that goal. Plus, as bike thieves become more aware of which e-bikes include built-in GPS or other theft deterrence features, hopefully those models will become less attractive targets.
The Pace 4 doesn’t only upgrade its intelligence. Its performance and comfort have also received their own improvements.
Powered by a 500W rear hub motor rated for a peak output of 864 watts and 60 Nm of torque, the Pace 4 provides decent power for smooth urban commuting and enjoyable leisure rides. According to Aventon, riders can expect consistent and reliable performance across various terrains and riding conditions.
It may not match the 750W continuous-rated motors we often see in the North American market, which usually output peak power in the low four figures of watts, but it should still provide good power and climbing performance on moderate hills.
The Pace 4 features a 36V 20Ah battery, which Aventon states can deliver a range of up to 70 miles (112 km) when ridden in ECO mode. Of course, few people actually ride solely in the lowest power mode, and so the real-world range is likely to be somewhat lower – especially for riders who make ample use of the throttle. But with just over 720 Wh of battery capacity, the Pace 4 is likely still ideal for extended city commutes, recreational rides, and weekend exploring. And with the included torque sensor, the pedal assist is more responsive, giving riders more reason to let go of the throttle and enjoy the pedal assist performance.
The 27.5×2.1″ urban tires will be most at home on pavement but can likely still handle fairly smooth trails. Whether for daily commuting or leisurely outings, the bike seems outfitted for a variety of use cases.
The Pace 4 lacks traditional suspension but the bike does include a suspension seat post offering 2 inches (50mm) of travel. This feature absorbs shocks and vibrations from rough roads, preventing them from traveling up through the saddle and into the rider’s rear, enhancing the riding experience. Complementing this is an ergonomic handlebar design aimed at promoting a relaxed, upright riding posture, reducing rider fatigue on longer trips and increasing overall comfort.
Neither of these can replace true front or rear suspension, but they go a decent way toward adding more comfort to the ride.
Aventon has also emphasized accessibility with the Pace 4. It features a step-through frame design that makes getting on and off the bike much easier than swinging a leg over the rear, helping the bike cater to riders of all ages and abilities. Available in two frame sizes and three colors of Flint, Mica, and Blue Steel (grey, black, and light blue), the Pace 4 also offers a bit of variation to help riders dial in the size and style closer to their tastes.
Priced at $1,799, the Pace 4 is entering the market at a time when new tariffs are hammering e-bike prices. The model is now available for purchase through Aventon’s official website and Aveneton’s wide network of authorized dealers.
Electrek’s Take
The new Aventon Pace 4 sticks with the company’s recent drive to push the boundaries of e-bike technology, combining smart connectivity, enhanced security features, modest performance, and some nods toward comfort. I’d imagine the bike would appeal to a broad range of riders if it wasn’t for the price, which feels fairly high to me. Plus, the base model doesn’t include a rack, fenders, or other commuter staples that will only elevate the price further. That being said, the Pace 4 launches at a time when e-bike prices are expected to arrive across the board, either slightly for models built in various Asian countries or significantly for models built in China.
But ignoring the price (as hard as that may be), I do like what I see here. It’s hard to compare to Class 3 e-bikes with more powerful 48V systems, but this isn’t designed to compete with those models. It’s a more modest, easier-going model. But for its intended audience, it comes with some nice features that we don’t often see elsewhere.
I really hope features like built-in tracking become more common across the board, as they’re hugely valuable for riders.

British Columbia got its first 400 kW DC fast charger last week at Canadian C-store chain On The Run, but that’s not the good part. As part of a limited time offer, these chargers are FREE!
The Canadian convenience store chain just took the wraps off its new, ABB-developed, 400 kW chargers earlier this month, but they’re already planning to bring the ultra-fast 400 kW dispensers to at least four more locations in BC this spring, and have them online just in time for the summer road trip season – something On The Run hopes its customers will appreciate.
“The A400 charger delivers an enhanced customer experience, with reliability and performance from a 32-inch screen to higher power charging sessions and power sharing,” reads the company’s official announcement, via LinkedIn. “Download the Journie Rewards app to start the charge – free for a limited time.”
On The Run’s new 400 kW ABB DC fast chargers are compatible with CCS and CHAdeMO plugs, and can accommodate Tesla and other NACS-equipped vehicles with an adapter. That said, the company seems to imply that Tesla drivers in particular will have a maximum charging speed of “just” 50 kW, which feel hilarious (given the current state of affairs between Tesla and the Canadian government), but probably isn’t.
In addition to the ABB A400 400 kW units shown here, On The Run locations also employ the ABB Terra 184 dispensers rated at 180 kW. On The Run plans similar deployments at the four BC locations mentioned above, as well as two more each in Quebec and Ontario slated to go live towards the end of this year.
Electrek’s Take
Tesla’s controversial CEO Elon Musk once mocked 350 kW charging speed as being “for a child’s toy,” despite the fact that, nearly nine years later, his own cars and Superchargers can barely make it to 325 kW while others have sailed right on past. I made fun of that fact on the Quick Charge episode shown, above – and, while I do think it’s funny and relevant, the much more relevant piece of news here is that companies like BP Pulse, Revel, and Wallbox are actively deploying 400 kW solutions, today (while others hit the same mark as far back as 2017).
It’s just a fact: Tesla has fallen way behind.
