Flux capacitor

A flux capacitor is a piece of technology used aboard 24th century Starfleet starships and facilities.

Flux capacitors were used aboard the USS Enterprise (NCC-1701-D). 

In late 2375, Miles O'Brien joked to Julian Bashir that the reason he was going to teach at Starfleet Academy was to teach officers the difference between warp matrix flux capacitors and self-sealing stem bolts. 

The following year, Thirishar ch'Thane overestimated twice the number of flux capacitors he and Nog would need for the new wormhole relay station the USS Defiant (NX-74205) (II) deployed.
