Of course this device is nowadays S-F. Surely I won't see it working, but I'm sure it will work soon.
Future Technology - Transporter
What kind of technology is required to scramble a person's atoms and send them for regrouping in foreign lands all in the blink of an eye? Imagine, I could work in Tokyo and sleep in Paris. Beam me up.

Another sure device tomorrow:
Future Technology - Replicator Technology (Stuff for Free)
Every time I saw Captain Picard (Star Trek Next Generation) ordering his Earl Grey Tea or Councilor Troy getting a triple alien fudge dessert from one of those replicators on the Enterprise, it made me jealous. I imagine you could send the dirty dishes back to the void where they came from. BTW, a replicator is a device that uses transporter technology to dematerialize quantities of matter and then rematerialize that matter in another form.
Transport and food forgotten for ever.
