The Active Denial System (ADS) is a directed-energy weapon developed by the U.S. military, designed for area denial, perimeter security and crowd control. Informally, the weapon is also called the heat ray since it works by heating the surface of targets, such as the skin of targeted human beings.
Sound like something out of a conspiracy nutjob’s imagination, but it’s actually real, and it’s terrifying.
Supposedly, it’s just supposed to have enough juice to irritate you enough that you don’t want to stay in the affected area. But I mean, it’s also a microwave beam that is capable of cooking you. 🤷🏻♂️
There’s others that use sound waves to make you feel queasy and nauseous by simply having super, super deep bass (low frequency vibrations). Though I don’t think it’s as effective as microwaving people.
