The replicator

One of the best technical advances that arose in the series Star Trek the Next Generation was the replicator. Users simply had to tell the machine what I wanted, and that it materialized from absolutely nothing.

The theory behind the technology was to reorganize the universally abundant subatomic particles to form molecules. The molecules are then organized to form the desired object. The Captain Picard was known for ordering "tea, Earl Grey, hot." However, the device was also used for the creation of machine parts and clothes. Any Geek would like to have one at home.
