Flux capacitor
A flux capacitor was a component associated with the flux capacitance of a starship's warp matrix.

In 2366, when Lieutenant Barclay was offering hypothetical reasons for one of the anti-grav units' failure, Wesley Crusher suggested that Barclay check the "flow capacitor", which flustered Barclay. Barclay then visited one of his fantastical Holodeck programs and ranted to a simulated Counselor Troi about the encounter, "I knew about the flux capacitor, but I didn't need to hear about it from some 17-year-old kid."

{{bginfo|Barclay's line in the script is "I knew about the flow capacitor..."; perhaps changed while filming or a mistake by Schultz. }}

After telling Dr. Bashir he was leaving Deep Space 9 to teach at the Academy in 2375, Miles O'Brien jokingly claimed it was because "somebody has to teach you officers the difference between a warp matrix flux capacitor and a self-sealing stem bolt''". ()
