So we keep it really simple, and we try to keep it manufacturable.

That's really the thing that we focused on, safety and manufacturability.

We want to build these really, really fast.

How big are you going to go?

So this is a good question, and I think I am purposefully trying to make sure I don't think I know the answer to it yet.

I have ideas.

Part of the whole point of technology is you have to discover things by doing them and by getting closer to them.

So I have lots of thoughts on how big you should build the eventual reactors that power the entire world.

I think that we know that the next reactor we build, the 1.7x scale-up of the current one that we have in Los Angeles, is the right size to hit an amazing price to be able to make the cheapest power in the world and to build them really fast.

So that's good enough, right?

And we'll start to scale with that.

Over time, I think it's likely that we'll get bigger and better.

But every time you get bigger, the safety gets harder.

So you have to pay a lot more attention to what happens in an emergency scenario, how to get the energy out of the core.

And it gets harder to build.

You have to have more advanced tools.

It's harder to transport.

The logistics get more difficult.

And so we think this size is like a really great way to hit the ground running, put gigawatts of power down onto the grid, power data centers, beat China on AI in the very immediate term.

And then over time, this is similar to SpaceX, right, where they start with the Falcon 1, which is a small rocket, and then Falcon 9, and now Starship is this huge rocket.
