Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

I see.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

But that cocktail you get, it's really variable because you're picking up trace molecules that depend on the room you're in, the humidity, whether or not someone's eating a hamburger in there, whether or not there's a power plant nearby, whether or not you're on Mars versus a vacuum system on Earth.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

And so the main idea is it's actually those trace molecules on the surface that make everything different and are driving the effect.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

Exactly.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

And in fact, we can take two samples.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

So the thing that, of course, clued us into this is what matters is we have a way to remove all of the molecules.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

So for a brief moment, they're clean.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

The objects really, truly clean on their surface.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

But because you're always in some kind of environment, the molecules start slowly redepositing.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

Yeah.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

But when we remove all of these molecules from two identical oxide surfaces, they really stop charging.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

So kind of what you're saying is true.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

Why?

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

Oh, that's a great question.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

So there are so many things.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

I'll give you a kind of a physicist fundamental lofty answer and then an application answer.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

Okay.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

So the lofty thing that keeps me excited is there are so many things in nature that depend on this effect.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

So like I said, you know, it is thought that the chemistry of life was made by sparks from static electricity.

Futureproof with Jonathan McCrea
Extra: Why can’t we figure out static electricity?

So if we don't understand how static electricity is generated, you know, we don't understand how the first amino acids came to be.
