The Great Pyramid of Giza was a Pulse Pump. (.com) You know, for free energy. Inspired by the work of Ram Pump inventor and "Pharoh's Pump" author Edward J. Kunkel, The Pharoh's Pump Foundation is dedicated to general pyramid pump awareness and answers many relevant questions. For instance: Is this Pharaoh's Pump stuff hallucinations of a raving maniac?

Fascinated by Egyptian archaeology? View and learn all about the discoveries in Giza, the Valley of the Kings (and Queens), Memphis and Saqqara and the Sphinx from the comfort of home. Depending on today's pesky sandstorms and time of day, you may even be able to see the pyramids from the comfort of your couch. Want to go inside? Yeah, me neither.

The Great Pyramids at Giza have never been accurately dated.
Conventional Egyptian chronologies are only accurate to within 100 years. Using a neat trick, scientists have been able to pin that date down to within a few years. When they were built, the pyramids where aligned northwards by using two stars as a guides. Over time, these stars have moved because the Earth's rotational axis "wobbles" slightly over a 26,000 year period. The orientations of the pyramids reflect this, the older pyramids are oriented slightly to the north east and the younger ones are oriented slightly to the north west. This information has been used to pin down their exact ages.
