Okay, most people are familiar with the Gurnsack TL. It's basically the World of Tomorrow... in 1960. A World Science Council is building a city on the ocean, energy is broadcast,tanks have particle beam cannons, etc.
It's got a fair number of neat concepts that, IMO, aren't especially implausible.
Among them:
-A more stable Weimar State
-Greater scientific development
-Saner Japanese militarists (who basically consolidate in Manchuria and Northern China)
-A European war against Stalin.
And of course, some ugliness; a surviving Fascist Italy, a Communist Spanish Republic, and delayed decolonizatoin.
Thoughts?
