I have a couple of Tomorrow's World annuals from the early 70's. Almost nothing they discuss ever actually worked, and in many cases was never built, (examples include walking diggers and submarine megatankers that can go underneath the arctic ice floe) they also include incredible predicitons of the world of 2040, a disturbingly fascist dystopia where everyone lives in kilometre tall white skyscrapers and is forced to wear contraceptive implants and are semi-voluntarily euthanised at the age of 60, described in awfully glowing terms that confirm every hippy dippy types worst ideas about scientists. Another one contains a timeline of the future, which is endlessly quotable for gems like:
"1986 Channel Tunnel closed for installation of magnetic accelerator/hover system"
"1990 Cure for Cancer discovered"
"1993 Average national working week 22-33 hours"
"1996 Thermonuclear fusion controlled and economically viable"
"1999 Ceation of intelligent artificial life achieved"
"2001 Manufacture of Elements to Order"
"2030 Average age of puberty reduced to 9 years old" (?????)
and the endlessly sad
"2016 2000th edition of Tomorrow's World"
I also have a great little book by war porn publishers Salamander called 'An Illustrated Guide to Space Warfare', which I read
endlessly as a young teenager. It doesn't have a date but it must have been written in the mid to late 80s, and it's essentially an in-depth description of how the Star Wars program was supposed to work, including some pretty unique pictures of early weapons tests, at least some of which I know for certain to be US propaganda fakes, such as the apparent accuracy of the bizarre
HOE missile, which was only achieved sporadically by linking the fire control computer of the missile with that of the one it was supposed to intercept. The main value though are the paintings of some of the ludicrous proposed Star Wars weaponry, like laser cannons the size of a 747 powered by open-circuit nuclear reactors, and for the intricately detailed diagrams that try to explain the tactical and strategic purpose of missile defence shields, anti-satellite weapons etc.
