Did a highly advanced civilization exist in prehistory? In a brilliant piece of reverse engineering based on 20 years of research, a master craftsman and engineer reveals that the Great Pyramid of Giza was actually a large acoustical device. By its size and dimensions, this crystal edifice created a harmonic resonance with the Earth and converted Earth's vibrational energies to microwave radiation. With 74 illustrations and 8 pages of photos.
