The Tesla thing reminded me that I saw a program that said the purpose of the tunnels in the great pyramid, and it's location over a running aquifor and location on a certain geometric magnetic line over the surface of the planet, was something along the lines of an acid was poured down the chute/tunnel, and them mixed with another chemical in the bottom. This resulted in a chemical reaction, combined with the geographic location resulted in the pyramid emitting usable energy. I dont' recall whether the energy was used to power things in the surrounding area, or re-fueling alien spacecraft, or what. but they did find traces of the supposed chemicals in the structure and chutes, and have replicated the whole thing in the labs.
Interesting or not?
