Soldiers barking orders at each other is so 20th Century. That's why the U.S. Army has just awarded a $4 million contract to begin developing "thought helmets" that would harness silent brain waves for secure communication among troops. Ultimately, the Army hopes the project will "lead to direct mental control of military systems by thought alone."
The Army's initial goal is to capture those brain waves with incredibly sophisticated software that then translates the waves into audible radio messages for other troops in the field. "It'd be radio without a microphone, " says Dr. Elmar Schmeisser, the Army neuroscientist overseeing the program. "Because soldiers are already trained to talk in clean, clear and formulaic ways, it would be a very small step to have them think that way."
