I'd love to hear about your favorite concept or idea you've read about or seen in scifi media.

My personal favorite is the Conjoiner Drive out of the Revelation Space series. These ship drives are dual drives on either side of a lighthugger and have a living being inside the drives to act as a supercomputer, which holds a wormhole open inside the drives. The wormhole links far in the past to the big-bang and uses the energy from the big-bang for propulsion.

In most scifi I've come across wormholes are used for FTL travel, and I thought this was such a unique and creative use of a wormhole it has stuck with me for years after reading about it.

So what are your favorite devices or ideas that have come out of scifi media?

The wormhole network of the Nasqueron Dwellers in "The Algebraist."

Niling d-sinks, from Peter F Hamilton's Commonwealth novels.

The Planet Express ship from Futurama (it would take too much energy to move the ship at FTL, so it moves the universe instead.)

Planet express ship is cool and all but I think the finglonger takes the cake

So many original ideas in Hamilton's work, I too liked Niling D-sinks.

I love the idea of the Niling d-sinks. With enough time, an individual can amass a nuclear bomb's worth of energy off of a simple low power source like a geothermal generator or solar array.
