Happened across a 1952 online Popular Mechanics as I was looking for something and this came up in the search results. Quite astonishing how its pages resonate in so many ways. Some positively; others negatively.
Things like:
Triple filament lamp so you could have 50, 100 or 150W. Hmm, doesn't that make sense compared with under-running to dim?
Super-reliable only one moving part oil boiler.
An extremely early Dremel - both of the sort we know/think of today and at least a saw.
Fluorocarbons to prevent fires.
Princess flying boat with 10 turboprop engines, 3500 miles range, 200 person capacity.
Post Office London underground railway.
A bit tedious viewing on my laptop screen but fascinating.
