Q And I guess while you were there, you, after that project, you decided to, to tackle another project around water electrolysis. Can you tell me a little bit about what that project was?
A Yeah. So after this solar powered toilet situation, I was looking around for what else to do. And a lot of folks at Caltech were working on splitting water in order to replace fossil fuels. And the idea was we could use clean, renewable electricity, split water into hydrogen and oxygen, and then use that hydrogen as a fuel to fuel everything we do today. And we wouldn't have to use any fossil fuels. And the scale of that solution was really compelling to me. That's But I realized that the technology had been around for over a hundred years, and we don't make hydrogen by splitting water today. We make hydrogen a different way from a fossil fuel, actually. And we do that because it's the lowest cost way to make hydrogen. And I didn't see a route for hydrogen production to become lower cost than the production from fossil fuels. And therefore, ultimately, I didn't see A chance for there to be a big impact. So I ultimately stopped working on that project too.
