All I know about solar sails comes from Arthur C. Clarke, but most importantly – from Count Dookie or whatever from Attack on My Childhood: Episode 99. Motherfucker all flies away after hacking off Emo Hitler’s arm, utilizing some sort of sailing device. Uh. Anyways, we have them as well, I guess. And a massive one is setting out in 2014, probably to hunt down Count Dookie and slay the living shit out of him.
