It has been my theory, for the past 30 years or so. That the Sarcophagi in the grate pyramid, is what is left of a grate power source.
And with the grate amount of power it can produce it is on a simple design. Has been over looked by some of the greatest minds of the world.
If you can take a 1/2''inch X 2''inch piece of Piezoelectric quarts crystal, and put set of electrodes on every other site, and tap into them, after applying about 1,000lbs of pressure all around it, equally. You can get about 10,000 Volts. Of course they say that it will explode after a while, because it will vibrate out of control.
Now just think if you had a crystal about 2' feet by 5' feet.
And you put it in a counter resonating box, to the frequency it vibrated, something like the Sarcophagi, in the Kings Chamber.
Just how much power do you think you can tap into. And as long as you control the pressure you control the power out put.
