To study "earth energy", in 1978 Paul Devereaux formed the "Dragon Project", which employed physical and psychic research methods. The name was taken from a Chinese symbol for terrestrial currents.
The Project first investigated the RollRight Stones, a megalithic site 20 miles NW of Oxford, England. Sensors recorded energies from a few minutes prior, to several hours after sunrise. Radiation and ultrasound energies were detected. A strong high frequency magnetic field was detected near one of the stones.
Project reseachers reported unusual visions, which Devereaux speculates may have been caused by mild hallucinations. Devereaux and his co-workers believe megalithic builders could sense these energy fields, and colocated their building projects with them.
