Wow! That is simply amazing!
It doesn't take an engineer to appreciate a Doble, but being one sure helps. I continue to be amazed at the sophistication of steam power developed back then - both for heating/industrial uses as well as motive power. Even more amazing is little more than 40 years later we were standing on the moon.
Not to get off on a soapbox tangent here, but in 1937 the hot ticket for travel was the "new" DC-3. In 1967 it was the Saturn V rocket. 30 years. I am 41 - born shortly after Neil Armstrong was standing in the Sea of Tranquility. I don't dispute the fact that there have been some amazing technological advances made in the past 30 years - Ma Bell and rotary phones? Today's smart phones were unthinkable back then. But all of today's electronic wizardry is just the same basic components made smaller and smaller - nothing really groundbreaking - just continued refinements. It is all above MY head, that's for sure. I play with vacuum tubes. Those I can understand.
I just don't see any huge breakthroughs of technology outside of electronics in my life so far, even though electronics have permeated every part of our existence and made so many things easier, safer, more convenient. But essentially, our transportation devices haven't changed, we still heat with coal
, and after driving little dune buggies around on the moon 40 years ago where have we gone? Nowhere. As the USA further and further shifts it's manufacturing base overseas and the corporate "fat cats" continue to run our remaining companies based on lining the shareholders (and their own) pockets at the expense of the average worker (and real engineering), we will continue to slide down the hill of technical talent until we (completely) become a society of lazy, uneducated socialists looking for the next government handout.
I get the sense that things might be starting to turn around - companies are FINALLY figuring out that low cost countries are NOT low cost in the end. We sourced wire harnesses from China - a move that was going to save a couple hundred grand. But, instead, the quality was so sketchy that we had people inspecting them 100% and that went on for a year. On paper, our sourcing department did good, but as a company we lost our ass - and that never shows up on the books because those costs are buried so far down. I've run across this same thing at almost every company I've been at and they never learn.
