If the technology is dissected, it will look strange and foreign and like it shouldn't work - it's not wired for AC or DC current, and the outlets are clearly not American or European standard. Moreover, only future is now characters can actually functionally build anything with this technology - otherwise, trying to take things apart to put them together again will just break the technology and render the parts defunct. There can be computers if you like, but none of the computers will work either without a character from future is now operating it. The computers won't even turn on for anyone that's not on future is now.

There are no laundromats.
