Who needs vocal cords or typing skills when you can create email or voicemail by only thought. Yes, I'm being serious. Mike D'Zmura from the University of California is the lead scientist on a new project to create a helmet to convey messages telepathically. Surprise...surprise. The army is paying for it.
Not exactly a new idea but a twist on an old one. Of course, if he succeeds the army will get first dibs and maybe...just maybe it will become available to us civilians in the future.
