"Pyramid power" is a term coined by Dr. G. Patrick Flanagan in his 1973 book, "Pyramid Power" for supposed supernatural properties of the ancient Egyptian pyramids and scale models thereof.

Pyramids of these exact relative dimensions supposedly act as an electronics antennae for an unseen energy similar in concept to KI. Flanagan's claims range from enhancing the nutritional value of foods to sharpening knives by placing them under such a pyramid overnight and are generally not considered credible, even within the alternative science community.

The book was featured on the cover and in the lyrics of the Alan Parsons Project album "Pyramid album Pyramid", contributing to its popularity.

The original book has long been out of print; a revised edition was published in 1997 as "Pyramid Power: The Millennium Science" (ISBN 0964881268).

Pyramid power was the subject of a famous spoof by Martin Gardner in his Mathematical Games column in Scientific American June 1974, featuring his favorite characters Irving Joshua Matrix Dr. Matrix and Iva Matrix.

Despite much criticism and disbelief, some individuals claim to have successfully replicated some of the Pyramid Power experiments. One such person is Dr. Volodymyr Krasnoholovets . A razor blade placed in a "resonator" was seen to become smoother and less angular over time [1].
