Okay.
I think I partly answered this. I agreed earlier with some of David's comments, because when you are going down a path like hydrogen, and even clean zero-emission biofuels, government does have a role to play. I'm not denying that. The economist in me, though, says to find that sweet spot. That's what I say when I'm making recommendations to government.
The energy system has a great history of governments putting all sorts of money into failures. What I try to point out is that there are ways to do it where you're letting the market still decide while you're helping out these opportunities. That's my approach.
