And a lot of folks talk about desalination and clean water so that we can be in places where there's not a lot of water and those things.

I actually think about food, ironically, is that how much of the Earth's surface that used to be nature is now farmland.

And we need it.

Like, we're going to grow food because humans need to eat.

And that's really critical.

But it's about five feet tall all over the Earth.

Why can't you do it at 500 feet?

Why can't you build a building that where you're actually growing in the building, you're growing plants?

I spend a lot of time thinking about growing plants, ironically, at high densities of food densities so that we can eat and we can exist and we can coexist in a way that's energy dense and rich.

You mentioned actually going to space.

You know, how do we go to space now?

We take methane fuels or hydrogen fuels and we burn them and we launch a rocket.

There's all kinds of cool beamed rocket technologies that I looked at early in my career where you can like beam microwaves.

And so you have a microwave craft that doesn't have to burn any fuel.

And so if you have really dense, really good power on Earth, you can beam it to that microwave craft.

It can now use electricity as its rocket fuel.

And so there's some really powerful, interesting things you can do.

Even deep space, it gets also more enabling.

But even just launching from Earth.

And so I think it opens up things we don't really even think about that have just been theorized.
