First heat-ray gun

According to Official Guinness Records,

The first heat-ray gun is the Active Denial System, which projects an invisible heat-energy microwave beam within a range of 500 m (1,640 ft). Typically, the gun is mounted on to a Humvee vehicle, and whilst a human target would immediately feel a burning sensation, the weapon is non-lethal. The gun was publically demonstrated for the first time, at Moody Air Force Base, Georgia, USA on 24 January 2007. The beam can penetrate clothes and heats up the water under the skin of a target individual in its path to 50ºC (122ºF).
