Death Ray (Particle Beam Weapon)

In the 1930s, Tesla described his "Teleforce" death ray as a charged particle accelerator projecting beams to vaporize targets miles away, patented elements in related high-voltage works. Designed as a defensive weapon to deter aggression, it used electrostatic repulsion for beam focus.

Never built, it influenced directed-energy research like lasers. Tesla's pacifist intent aimed at global peace, but it sparked ethical debates on weaponization, echoing in modern non-lethal systems.
