 If I were to compare my jewelry making materials and hobbies to hydrogen, I think the biggest overlap there is probably in the safety of it. When you're working with jewelry and metals, you have some dangerous equipment. You know, you might have a torch, you have open flames, you have things that are going to be hot and sharp. And hydrogen is also something that you have to be respectful of when you work with it. And so, you know, a lot of the safety that we're doing here, I would say, is elevated from what you would have in a jewelry shop. But the philosophy is the same and that we want our folks working on it to be as safe and protective as possible.
