Hey Walt, Love starting my day with NN. Just a quick piece of advice: Tap on the brakes while you're copy editing. You don't want to break anything.
Anything that gets us off that petrol crack pipe (for our cars) is a good thing all around. It's good for the environment, it's good for our foreign relations (in that it will make us less beholden to countries that despise us), etc., etc. So, come on hydrogen fuel cells!
