What sci-fi object do you wish was real? - no deloreans allowed

[parsnip]

If you could make one fictional object from a sci-fi movie/show/book exist in the real world, what would you pick?

No time machines, that's too easy.

 

[Gangstalker #32194]

Nanomachines, son!

 

[The Real Me]

Portal's Long-Fall Boots would be fun and practical!

 

[Hamsteroid]

Oh, wait, these already exist - never mind.

 

[SpergioLeonne]

Asian women

 

[Gog & Magog]

Lightsabers
I wanna effortlessly cut people in half.

 

[Pierre D'Olnique]

The nanosuit so I'd no longer need a car for anything. Stealth mode could prove useful in avoiding Jehova's witnesses.

 

[Xenu]

I would choose SCP-999 if SCP is considered as Sci-Fi. If not I choose a World Cracker ship from Stellaris.

 

[SSj_Ness (Yiffed)]

Enertron from Chrono Trigger. It heals anything, even malnourishment.

 

[Grub]

Star trek replicators. I can make all the other cool sci fi shit with them.

 

[Poppavalyim Andropoff]

Teleportation

 

[not william stenchever]

I'll go with the boring but practical choice of fusion power.
