My A-Z book for children got rejected; switching gears, making it for adults

A literary agent rejected my children's book on A-Z future inventions/technologies/concepts. Now I'm going to try it for adults but I feel my list is too generic. I made it so kids could understand it. Now I'm doing it for adults so their is no handicap. Here's my list

Antimatter rocket
Brain implant
Clone
DNA scanner
Eclipse magnifiers
Fusion reactor
Genetic engineering
Herculean serum
Invisibility Jacket
Jupiter brain
Klingon
Laser cannon
Maser
Nootropics
Omega Point
Prosthetics
Quantum computer
Radiation sponge
Starship
Time dilation device
Unmanned vehicle
Vitamin X
Wormhole
Xenobiology
Yoctotechnology
Zygote freezing

As you can see, my list kinda sucks. Anybody have better ideas? Use science but limit the technobabble. One per letter. Just one

Thanks

Switch Clone with Condom and you'll win yourself a Pulitzer, my friend.

Cool idea! I like the list, but maybe swap Starship for something more specific (since you got some pretty specific things in there), like Soyuz?

I don't really see anything wrong with the list, just go full-on sci-fi genre! Just remember to take a new, unique twist on the genre. :D

I though about making a children's book about hacking, where the 2 main characters are Alice and mAlice. They both grow up and go their separate ways, as a white hat and a black hat. The goal would be to teach kids what hacking is about. I doubt I'll ever get around to it, though. XD

Rename Tim's Dilation Device to TARDIS
You got it

What adults do you want to market your book towards?
