The Navy is developing a vomit gun. Yes, a vomit gun.
Invocon Inc., funded by a Navy contract is developing a weapon that can shoot invisible beams through walls and cause people to get dizzy and fall over. The beam can also cause motion-sickness that can induce vomiting. The gun shoots RF energy that excites and interrupts a human's hearing and equilibrium.
