Unfortunately, as I'm not an electrical engineer, its hard for me to thoroughly assess this idea, but I like how it incorporates many of the elements of the great pyramid designs. He jumps back and forth a bit in his explanation purposefully to clearly explain the idea. I think its done well enough not to lose me along the way in his explanation.
Its pointed me to some other area's in my attempt to explore it further and I've discovered the "Electrical Universe Theory", which is another area beyond my ability to evaluate sufficiently. But this theory and its believers would be the ideal group to chime in on the validity of this above Great Pyramid Maser concept.
Anyone have any interest in these ideas and can pass along some links or names to follow up on?
