Whether people like it or not, nuclear power is the path forward for the foreseeable future; at least until nuclear fusion becomes a reality. With incoming AI/automation, ya’ll need all the power ya can get.

With basically almost nothing coming online for decades and the handful of projects that do come online being late, hundreds of percent over budget, and delivering only a relatively tiny amount of power (relative to the equivalent of hundreds of new reactors worth of solar/wind/battery every year), it's hard to maintain that nuclear has any role whatsoever to play. No amount of magical thinking is going to change that any time soon.

The AI revolution will be mostly over by the time any substantial amount of new reactors come online. Whatever power they'll use, it will mostly not be nuclear. It's a lot of gas right now that will likely shift to a mix of much cheaper solar and wind. Nuclear powered AI will be a rounding error.

Maybe somebody will figure out how to do new nuclear plants in under a decade (good luck!). That would be spectacularly fast. But if it's not planned and approved right now (and very little is), we're basically talking the 1940's for any significant new capacity to come online. That would still be a tiny fraction of the yearly growth in renewables. That probably will accumulate to about three orders of magnitude more power generation in the time until then. With hundreds of GW added per year, we are talking at least a few TW of generation cumulatively.

"Decades" is an extreme POV. Big tech companies are actively investing into nuclear power. Unlike those green renewables you described, nuclear runs almost nonstop. At least 90%+ of the time! Let's not forget about China, who can do it faster and cheaper compared to western standards.

Obviously short term we'll be forced to use gas, renewables, etc. But saying nuclear will be irrelevant is wrong.. Reliable 24/7 clean power without the need for massive amounts of batteries or land is ideal.

It's not clean though? It requires massive amounts of mining and refining to even get the fuel, and it's no more renewable than fossiles
It requires least amount of mining vs alternatives, where did you get this weird false narrative https://ourworldindata.org/low-carbon-technologies-need-far-... ?
If you include Uranium in the oceans, we have about 4.5 billion years of fuel.

It's no less renewable than the Sun.

In general, “clean” as in zero carbon and air pollution
Yeah what the hell, I want tiny and small nuke-batteries so we can finally get cars and phones that doesn't need charging anymore, would solve a lot of problems and surely won't introduce any new ones.
What you really need is 24/7 power supply, it might become a luxury to have uninterrupted electricity exactly as it is a luxury to have enough of fresh water.
When you're in one place, you'll just have a battery+solar I bet, but for when on the go, maybe for days, having a tiny nuclear battery that lasts N years would be great.
Check "Burevestnik" nuclear rocket, seems Russian scientists have developed a compact nuclear battery if to subtract the rocket from the power device.
> It is considered the first nuclear-powered missile and nuclear-powered aircraft

Very interesting stuff, even though the origin probably means we won't get much details on it until decades later. Thanks a bunch for sharing!
