http://www.projectrho.com/public_html/rocket/index.php This is one of those random pages that came up in a G+ discussion thread, and I thought it was interesting. A lot of science fiction discusses the idea of "atomic rockets." Of course, that's such a broad phrase as to be useless, but I like to think of it as rockets with "atom bombs going off on the ass end, creating reaction thrust." Anyway, ProjectRHO is kind of a fun site to just click around. It's created by Winchell Chung, who created - apparently somewhat by accident, while still a high school kid, the iconic look of the Ogre super-mega-battletank (yeah, I had to go look it up, too, but the history of the look is a fun story). I don't get the "RHO" reference. Apparently I'm not cleared for that. If you get the joke, please fill me in, yah?
