  You understand that i know what the answers are. I'm providing a range of questions for those starry-eyed among us who forget the everything has externalities. Way to jump to conclusions about who I am, what I know do or do not know, and what I may or may not believe in.

    That's rich, as your post was all about jumping to conclusions, literally from the first paragraph.

      That's a bare-faced lie. I responded to and elaborated on this comment, “That comment has very little substance. Where do you get the hydrogen? Where do you get the jet fuel? The answer determines if it's environment friendly.” Please point out to me what conclusions I jumped to. And that comment was a response to your false claim which was, “As a hydrogen engine it is also carbon neutral. That makes it more environment friendly than both the existing jet engines and Musk's methane rocket hopper.” You're just sore that it's being pointed out to you that hydrogen engines are not carbon neutral, not with the current incarnation of the tech. You may not like what I'm saying and the position I'm taking but you're arguing in bad faith to say that I'm jumping to conclusions. Hypocritically, by claiming that I've not read up on this stuff (when I most certainly have) you're the one actually jumping to conclusions.
