Every book is a time capsule, preserving knowledge and attitudes current at the time of writing, as I said in my previous post.
The NQCC garage sale donations which provided these time capsules were particularly strong on the nuclear debate. It was an urgent issue in the 1970s, with Peak Oil on the horizon and the dangers of nuclear technologies very much in the public mind from Hiroshima (1945) and the Cuban Missile Crisis (1962).
Renewable energy was so paltry that the energy debate was simply nuclear vs fossils. CO2 emissions did not figure in the energy debate at all, either. Why not?
