S1, E3: High-Frequency Active Aural Research Project or H.A.A.R.P. is a combined effort of the Air Force and Navy ostensibly designed to influence the weather. Consisting of large fields of high-energy projectors, this brainchild of controversial inventor Nikola Tesla, has been associated with everything from the breakdown of the ozone layer, to electromagnetic warfare. H.A.A.R.P. has achieved long-range undersea communications, but its clandestine applications as a long-range particle beam weapon able to alter the electrical impulses of the human brain are what make the technology controversial.
