Nicely written.

However you downplay Australia's great contribution to the clean energy of the future, being the 6th largest supplier of nuclear energy in the world. One way Australia pays for all those Chinese solar panels and wind turbines is by providing nuclear fuel it takes to build a modern industrial economy. Thanks to Australia for doing so much to keep China healthy and productive!

Now I know if you took Nuclear energy as seriously as it deserves, you would have to stop hand-wringing and work on nuclear energy. I'm quite sure nuclear industrial quality baseload can be 10x cheaper than the cheapest fossil fuel. It won't kill solar though because solar will get 8x cheaper than today when built with nuclear's diminished embedded energy costs for the Silicon and Aluminum.

Some will be sad if the effort that people have put into energy efficiency for the last 50 years would be mostly thrown away. The only losers when we make clean energy cheap, are fossil asset owners, and energy efficiency plays.

The good news about nuclear is it is NOT flatlining. It can look that way when you are living in fossil states. In the post-industrial service economies that have exported all manufacturing to China there aren't a lot of engineers in positions of influence. But every tech company has invested in one or more innovative fission plays, and most have made comical thrusts at fusion too.

As nuclear energy has not been significantly changed for 50 years, when an updated reactor is shipped, it will be at least 11x cheaper. (That's the minimum 5% advancement per year any industry can do.) But in 40 years solar got 100x cheaper. Nuclear should be closer to that... We see several orthogonal ways to rapidly yield order-of-magnitude cost downs with safety and reliability improvements.

No one can know the cost or quality of a manufactured thing until the factory that makes it has 5 years to streamline supply chains and manuf equip. But there is no factory on earth making nuclear modules. Without manufacturing, we have no clue. But it's the difference between a Rolex and a Timex. Except the industry still wants to sell us a Grandfather clock. And we should have figured out the Casio digital watch by now. That's where you get your 100x cheaper nuclear energy! The Transistor Changes Everything they say.. but we are still using nuclear designs from the Vacuum tube era. Because that's what the Oil Industry captured regulators want.

The anti-nuke cult was built to kill the grotesquely huge nuclear arms race. Some activists, notably the Sierra Club, decided to exaggerate the danger of nuclear energy, believing people were too simple to make the distinction, and the existential threat then was the crazy scary & costly arms race.. It's time to grow out of anti-science dogma that nuclear is somehow the most dangerous technology, when a half century of experience puts it among the safest technologies, and far lower in climate pollution and unhealthy pollution than even wind and solar.

Most importantly every nation on Earth can be energy self-sufficient with nuclear, at great savings in cost and trade balances. Landlocked nations and Islands far from trade routes would be equal. That means we would not need to fight the Oil Wars anymore, as no one would care who has fossil hydrocarbons. With industrial energy 10x cheaper we can make synthetic hydrocarbon fuel, and keep those Prius's running around forever. Also power Lufthansa's fleet with Sustainable net zero aviation fuel, which is trivial to make, but they need lots of energy. Half as much as Germany uses now. But it's trivial to make 20 times as much energy as Germany uses now with nuclear, and everyone benefits.

There are 3 key attributes for success in nuclear fission that's dramatically cheaper. Manufacturing. Hot. and Dry.

Hot means 600C output. So it couples to cheap turbines, and minerals, chemical, pyrolysis processes. At that temp you can actually repower existing Coal turbines and Methane Turbines. The cheapest power plant is probably repowering the existing one, preserving the grid, customers, labor, and political support. Note the real estate near a coal plant, AND ALL THE TRAIN TRACKS, increases in value which dwarfs the cost of the conversion.

Dry means no water touching fuel. That means no containment building is needed, which makes it small enough to fit in those coal and gas facilities... One at every substation would be nice. Inherent safety stems from designing out the explosive potential of Steam and the dreaded H20 -> H2 + O2 -> H20 recombination explosion that blew the roof off Fukushima Daiichi.

There are many startups with different takes on hot, dry, manufactured reactors.

I avoid the term "SMR" because it usually means not-so-small, not manufactured, not dry reactors, which are unlikely to be 10x cheaper than fossil fuels, and therefore are unlikely to displace the incumbent industry.

Uneconomic energy systems like too modestly improved fission, or fusion, or the Hydrogen Hype Economy are popular with the Fossil cartel that stridently support all impossible alternative energy schemes. Wind and solar however have great value to the Gas business because they will be in the money for decades, betting on every cloud bank that approaches the wind and solar farms. Gas gets to party every afternoon at 4:20 when Solar takes the day off and they sell wee bits of Gas at Fabulous prices to save us from the manufactured emergency. That seems to be why California's consumer energy prices go up as "cheap" but random wind and solar fill the role of the Casino's roulette wheel.
