I'm John Bachelord, Dr. Ken Croswell, an astronomer, author of The Lives of Stars, and we're

0:09.7

talking about the origin of lithium.

0:12.2

Why is that important?

0:13.4

It's called white gold.

0:15.8

It's extremely valuable, but it turned into the lithium ion batteries that power the

0:21.4

Teslas and all of the other electric vehicles that are coming for the next century as we

0:26.2

move away from fossil fuel generated engines.

0:29.9

However, I learned from Ken that it wasn't until recently that anybody had observed lithium

0:35.4

actually being made in Novi.

0:37.3

How did they do it, Ken?

0:38.8

Well, this is what's very interesting.

0:41.0

The theory was worked out.

0:42.5

We were just talking about the theory of lithium production in Novi.

0:46.2

That was worked out in the 1970s and a prediction was made that Novi should be major producers

0:52.4

of lithium and the galaxy and here on Earth.

0:55.7

But nobody actually had seen any lithium arising in a Nova.

1:00.6

And even though people did go out and look for the lithium, they never found it.

1:05.6

And then in 2013, everything changed.

1:08.2

When two different astronomical teams, two different continents made the discovery of

1:16.3

the Beryllium 7 and also lithium in Novi.

1:21.8

One team was led by the Japanese and they detected Beryllium 7 in a Nova that occurred in 2013.

1:28.9

And then the second team, which was unaware of the first team's work, was based in Italy
