Electricity output, now you can actually build systems of similar size and similar energy, only they're now at this much higher efficiency.

And that gets to one of the other price that gets to money.

So our goal is we want to build clean, low cost electricity and get it out in the world.

But that means it needs to be low cost.

That's fundamental.

If it's really expensive, no one's going to buy it.

And while it can be clean, it's not going to be deployed.

And so that is always has to be a part of why, what the promise of fusion is that can be low cost.

So that's,

How do we know how much fusion systems cost?

It's a really great question.

And a lot of it comes down to fundamental size, that you have to just build things.

And so there's some really first principles cost engineering you can do around power plants for fundamentally, what do they cost?

How much concrete went into it?

Fundamentally, how big is it?

And that if you're doing a good job of manufacturing,

your goal is to manufacture a product for as low of cost as you can.

So you can sell it for as low price as you can.

It asymptotes to the material cost.

Because you never get cheaper than that.
