What topic is most intriguing to

you? So in the, let's see, I've been working in this industry since 1974.

And a lot has changed in that half century, but some things haven't.

So I'm going to talk about something that has changed and hasn't changed.

So when Fred Schweppe, who was a professor at MIT, electrical engineer, conceptualized in the late 70s the idea of coordinating consumer decisions and generator decisions with locational marginal prices.

So using security-constrained unit commitment and dispatch and looking at the marginal costs and then settling transactions based on that.

That was a revolution.

I think, Ben, you've done some thinking on this, obviously, for a long time, maybe.
