The author in the book I just received (Giza-The Tesla Connection - my current thread here :
ENER - GIZA - The Tesla Connection. )
about the Great Pyramid being an electron generator / power source starts out about how our modern technologies were inconceivable to even us only 50 years ago much less 100 years ago and totally unrecognizable from the technologies at the beginning of the steam age about 230 years ago. At each stage of the evolution of technology, the next inventor stood upon the shoulders of the previous giants, furthering planetary progress, until some collapse of said planetary civilization hit some level of collapse so immense (ice age? Mini nova?) that no one who survived was able to remember, re-create, or operate the previous accomplishments. And so Solomon apparently knew enough via the Holy Spirit that he was able to convey to us that “there is nothing new under the sun”.
