Some Notes for The Centuries Unlimited

If science fiction is about what we think the future will look like, an alternate history with a Point of Divergence in 1929 (when people from the future arrived bearing technological gifts) should look a lot like 1920s scifi. So a survey of the genre at that time reveals that my book will be full of this sort of nonsense:

hover-pack

particle accelerator-field generator

disembodied intelligence

improve conditions for the poor by giving them fish gills!

disintigration ray

robots with hollographic costumes

glass buildings

Sorbing (brain-draining)

rockets

gap between ruling and working class

giant dangerous animals (the fatal eggs)

freeze ray!

death ray

insanity ray

ray guns
