Wrote The Giza Power Plant : Technologies of Ancient Egypt
"Christopher Dunn has an extensive background as a craftsman, starting his career as an indentured apprentice in his hometown of Manchester, England. Recruited by an aerospace manufacturing company, he immigrated to the United States in 1969. Over the past 49 years, Chris has worked at every level of high-tech manufacturing from machinist, toolmaker, programmer and operator of high-power industrial lasers, Project Engineer and Laser Operations Manager. For the past 16 year, he has served as Human Resource Director for a Midwest aerospace manufacturer.
Chris's pyramid odyssey began in 1977 after he read Peter Tompkins' book Secrets of the Great Pyramid. His immediate reaction after learning of the Great Pyramid's precision and design characteristics was to consider that this edifice may have had an original purpose that differed from conventional opinion. After further research and study of source material on various theories, Chris concluded that it must have originally been built to provide a highly technical society with energy—in short, it was a very large machine. Discovering the purpose of this machine and documenting his case has taken the better part of twenty years of research and following the 1998 publication of Chris’s book, “The Giza Power Plant: Technologies of Ancient Egypt” which describes a holistic energy device that is harmonically coupled with the Earth."
