Star Trek: 11 Incredible New Technologies That Were Immediately ABANDONED

6. Cristóbal Rios's Magical Doodad

After the crew of La Sirena crashlands on Coppelius and encounters Dr Altan Soong and his synth colony, Rios is gifted with a magical device. This device is a thought-based replicator named a Fundamental Field Replicator. Simply by using one's imagination, one can make this device fix, or create, almost anything. 

The device fixes critical components on the ship, bringing the ship back to full power. In the skies orbiting the planet and facing Commodore Oh's fleet, it creates images of hundreds of La Sirenas to confuse the Romulan sensors.

This magical doohickey, similar to the Doctor's Sonic Screwdriver, can seemingly do whatever is needed for the plot at that moment in time - until it can't. It surely would peak the interests of any engineer or scientist desperate to understand its flagrant shattering of the laws of physics. However, instead of becoming the new golden item at the Daystrom Institute, Rios obviously breaks it a moment after La Sirena goes to warp at the end of Et In Arcadia Ego Part 2, never to be mentioned again.
