The Future Is Wow
What if the techy transportation of sci-fi movies isn't as far-fetched as it seems?We asked Seth Shostak, scientist and film consultant, to rate them on a scale of 1 ("dream on") to 10 ("totally feasible").

"Pneumatic tubes at every residence would allow people to shop on the internet and have their products delivered without jamming up the roads with delivery trucks. But putting people into pneumatic tubes runs into problems both technical (you need pumps every few hundred tube diameters) and physiological (do you want to be stuffed into a small cylinder and sent at high speed around a bendy tube roller coaster?)."
