"...in some way they are able to generate an intense heat in a chamber of practically absolute non-conductivity. This intense heat they project in a parallel beam against any object they choose, by means of a polished parabolic mirror of unknown composition, much as the parabolic mirror of a lighthouse projects a beam of light... it is certain that a beam of heat is the essence of the matter. Heat, and invisible, instead of visible, light. Whatever is combustible flashes into flame at its touch, lead runs like water, it softens iron, cracks and melts glass, and when it falls upon water, incontinently that explodes into steam." ~ H. G. Wells - The War of the Worlds
LA authorities plan to use heat-beam ray in jail

LOS ANGELES – A device designed to control unruly inmates by blasting them with a beam of intense energy that causes a burning sensation is drawing heat from civil rights groups who fear it could cause serious injury and is "tantamount to torture."
The mechanism, known as an "Assault Intervention Device," is a stripped-down version of a military gadget that sends highly focused beams of energy at people and makes them feel as though they are burning. The Los Angeles County sheriff's department plans to install the device by Labor Day, making it the first time in the world the technology has been deployed in such a capacity.
...The device was made specifically for the sheriff's department by Raytheon Missile Systems. Sheriff's spokesman Steve Whitmore said its $750,000 cost was paid for by a Department of Justice technology grant.
