Y'ever see objects, vehicles or ideas in an anime or sci-fi flick and think Man, why don't we have one of those? We're loving Wired's "10 Sci-Fi Techs We Could Build If They Weren't So Damn Expensive", where they've sat down and calculated (estimated) how much certain items of wonder would cost. Got any guesses on how much a New-York-to-L.A.-maglev train would run you? How about a TransAtlantic tunnel linking Europe to America, or an actual Mobile Suit Gundam? We'll give you a hint on the latter--with an estimated "seven engines and thirty helicopter motors," it ain't cheap!
