So this *video (25 1/2 min long) on how the pyramids may have been sources of power long before the Egyptians showed up, was fascinating. It also talks about how Tesla was trying to imitate that, but J.P. Morgan pulled the funding when Tesla told him he wanted to make electricity free for everyone. Nope. That went against all the companies Morgan had his fingers in.
What I'm hoping is that some genius, who gets funding from God, not from a greedy multi-billionaire/millionaire, sees something like this and has the mind to make it happen.
I really think there is a LOT we don't know about the ancient people. We don't really have a monopoly on brains or inventiveness.
*Ignore HeckleFish. I don't know why they put him in there - but he does talk less as the video goes on.
