MEDUSA: Microwave crowd-control raygun

[Dave Monroe]

July 18, 2008

As part of the U.S. Navy's investigation into futuristic nonlethal
weaponry, the Sierra Nevada Corporation  is building a Microwave
energy pulse gun that can produce a painful screaming sound inside a
person's head from a long distance away. The inescapable sound, which
is inaudible to untargeted bystanders, can be set to irritate,
nauseate or even incapacitate people and animals that lie within
range. Future applications may include crowd control, military use and
even shopping mall security, provided it proves safe from permanent
side effects. The science behind it also has the potential to give
hearing to certain deaf people, or even projecting voices into
peoples' heads....
