If we'll need that flamethrower in space I don't want part of it. I've seen how those movies end.

People imagination is sometimes beyond me. The guy is clearly a space nerd since he was a kid. He loved video games and sience like many of us.

He has also spent 100s of millions of his own many to realize his dreams. But sure, its all a synic ploy to get the support of people on reddit and hacker news.
