What's your background there?

So I had a buddy of mine that I guess him and his grandfather used to play golf a little bit.

He called me up one day, and I think we were in sixth grade or seventh grade, and he said, hey, I'm going out to play golf.

Do you want to go? I'm like, I don't have clubs.

I don't have balls.

I'm like, nothing.

He goes, I've got clubs for you.

good with that.

That's where it kinda started for me.

Yeah, there was three great holes we can look at.

You know, the three...

Looking down, uh, looking down 10 there.

That was a great hole.

That's, you know, one of the hardest on the golf course.

And then looking up 18, you know, 18 green sitting in front of us.

Um, what was your favorite hole?

Tell us about that.

Yeah, it's quite exciting.

So it's a technology that stores energy by rusting and de-rusting iron.

So it's an electrochemical battery similar to a lithium ion battery, which would be the standard battery today.

But as I said, it uses iron, air and water.

And what's particularly novel about this technology is that it can store and discharge energy for 100 hours.

So your typical lithium battery will do anywhere from half an hour up to eight hours of storage duration.

Isn't that still the problem?
