The Secrets of the Giza Pyramid Machine Revealed! Did a highly advanced civilization exist in prehistory? Is the Giza Pyramid a remnant of their technology? Then, what was the power source that fueled such a civilization? The technology of harmonic resonance, claims renowned master craftsman and engineer Christopher Dunn. In a brilliant piece of reverse engineering based on twenty years of research, Dunn 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. The author shows how the pyramid`s numerous chambers and passage- ways were positioned with deliberate precision to maximize its acoustical qualities. This may be the same technology discovered by Nikola Tesla and the solution to our own clean energy needs. Chris Dunn has provided us a valuable addition to the growing body of knowledge concerning the recovery of Ancient Wisdom. This is the most important book concerning the Great Pyramid written in the last twenty years. -- Stephen S. Mehler, M.A., Director of Research, Kinnaman Foundation First West and Schoch redate the Sphinx, then Bauval finds Orion in the Pyramids. Now Dunn demonstrates that Egyptian artifacts were machined out of stone. Egyptology will never be the same! -- Jeffery D. Kooistra, Analog Science Fiction and Fact Magazine Christopher Dunn is a master craftsman and engineer with thirty-five years of experience. In the last twenty years, he has published a dozen magazine articles on his theories about ancient technology, including the much quoted Advanced Machining in Ancient Egypt in Analog. Dunn lives with his wife and children in Danville, Illinois.
