Christopher Dunn is a master craftsman and engineer in the aerospace industry. His astounding discoveries demonstrate that the technologies necessary for building the great pyramids of Egypt were far more progressive than anything ancient peoples were previously thought to have known. Dunn presents convincing evidence that advanced machinery was used to cut and measure ancient monuments with amazing precision. For a grand finale he introduces his astonishing theory that the great pyramids were actually used as ancient power plants, not as tombs, and goes into great depth explaining their inner workings.
