Lol, a technology we can't make work economically WITH economies of scale and on site experts will now be offered without those benefits.

Is this not what we expect from technology? That over time it becomes commodified and increasingly easy to operate?

I really wanted this to be about Rolls-Royce Motor Cars Limited rather than Rolls-Royce Holdings plc. A nuclear-powered Rolls-Royce Phantom would be incredibly boss.

Would a nuclear powered EV ever need refuelling?

I remember Toshiba having a decay-based laptop battery in development (at least 10 years ago, maybe 20). You wouldn't have to charge, ever. Now that would be something!

We shouldn't be using nuclear energy for power. Solar, wind and batteries will solve that.

What we should be doing is using nuclear energy for HEAT. We need a LOT of heat for a variety of chemical and industrial processes, not to mention heating of homes in colder climates. For these uses nuclear fission has massive potential.

>Environmentalists are divided over nuclear power, with some maintaining it is dangerous and expensive, while others say that to achieve net zero emissions by 2050 all technologies are needed. Yes, a mix of technologies. But there's more to it than that. We're going to need increasing amounts of power in the future to explore the solar system and to solve all kinds of existential problems. Energy usage is not inheren…

baby steps I'd say. Let's first fix all the mess we are making here on earth before thinking of space exploration.

No.

Agree completely. It's a fallacy to believe we will require less energy in the long run. We need much more, if we want to advance as a species.

That sounds like a very bad idea. Although I am confident that the tech has evolved since Chernobyl, terrorism has evolved as well. It just takes a bunch of assholes to destroy a small town. And yes, I think they will be pretty well guarded. But if you have lots of them some of them will have security flaws.

> terrorism has evolved as well I stopped worrying about terrorism when I realized that they could easily take out most of the European power grid with a few well-placed bombs on the central very-high-voltage power lines. Yet for some reason, they don't. If terrorists were really hellbent on killing as many enemy civilians as possible, the world would look very different. What actually seems to be happening is that t…

Interesting idea. I'd say they are just not intelligent enough to really figure out how to kill as many as possible. If they where intelligent, they would understand that terrorism rarely works in achieving its stated goals and do something more likely to work out in their favor.

"Production line mistakes may lead to generic defects that propagate throughout an entire fleet of reactors and are costly to fix," (person from University College London) warned. Wouldn’t the knowledge gained by fixing a large one-off reactor be of limited transferable value, as compared to expensive knowledge that could be used to upgrade an existing “fleet” plus improve subsequent versions?

The point is that every mistake propagated over 10 reactors has to be fixed 10 times. If you have a single reactor, you just fix it once.

That's a massive benefit. That means there 10 opportunities to optimize the process.

The point is rather short sighted: after fixing the production line issue, you make another 100 and recoup the expense of those first 10.

You can also just decide to get rid of the first 10 and never repair them because it's cheaper to build 10 new ones.

Yep, and nuclear is the only near-infinite source of energy.

When I was five or so, I had a watch with a radium dial.

I read in a kid's science book that if you went to bed and waited until your eyes were adjusted to the dark, and then held the watch dial against your closed eyelid, you would be able to see the sparks as individual radium atoms decayed.

I did this, and it worked! I could see each spark!
