John DeSalvo discusses the pyramid research of Joe Parr on the History Channel.
Joe Parr is one of the few people who has spent an entire night on two separate occasions (1977 & 1987) on top of the Great Pyramid conducting electrical, magnetic, and radioactive measurements all night long. Parr developed in his laboratory methods for working with the pyramid energy and found interactions with the gravitational field.

Dan Davidson has been able to verify some of Joe's findings.
