#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

And you can even imagine using small artificial black holes as thermal generators, right?

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

So the Hawking radiation from them

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

kind of exponentially increases as they get smaller and smaller in size.

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

And so a very small black hole, one that you could almost imagine like holding in your hand, would be a fairly significant heat source.

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

And so that raises all sorts of prospects about how you might use that in an engineering context to power your civilization as well.

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

Yeah, it is surprising.

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

I think people tend to think that we're close to this scale.

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

The Kardashev Type 1 is defined as a civilization which is using as much energy as is essentially instant upon the planet from the star.

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

So that's a border, I think, for the Earth of something like 10 to the 5 terawatt, so 10 to the 7 terawatt is a gigantic amount of energy.

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

And we're using a tiny, tiny, tiny fraction of that right now.

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

So if you became a Kardashev Type I civilization, which is seen not necessarily as a goal unto itself, I think people think, well, why are we aspiring to become this energy-hungry civilization?

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

Surely our energy needs might improve our efficiency or something as time goes on.

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

But ultimately, the more energy you have access to, the greater your capabilities will be.

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

I mean, if you wanna lift Mount Everest into space,

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

There is just a calculable amount of potential energy change that that's going to take in order to accomplish that.

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

And the more energy you have access to as a civilization, then clearly the easier that energy achievement is going to be.

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

So it depends on what your aspirations are as a civilization.

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

It might not be something you want to ever do, but...

Lex Fridman Podcast
#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

Yeah.

#355 โ€“ David Kipping: Alien Civilizations and Habitable Worlds

I mean, computation is a great example of, I mean, already, I think something like 10% of US power electricity use is going towards the supercomputing centers.
