I used to love reading Popular Mechanics when I was a kid (and later, OMNI magazine)...it had all sorts of futuristic ideas. And at that time, everyone beleived that we would be on Mars, have a Moon colony, floating sky cities, eat meals in the form of pills and all sorts of cool things (kind of like the Jetsons, in a way)...
I posted a book I got recently along these lines, it's a great read:
