As Kamen takes the stage for his three-minute talk, he explains that a
“very senior” official in the Defense Department came to him last year. We have 1,600 kids
who have come back from Iraq and Afghanistan without an arm, this official said, and right now we’re giving them a hook, the same technology we’ve used since the Civil War.

their mouths without crushing it. And build
it so that they can detect the difference between the two -- between the raisin and the grape -- by touch. -Wired Blog
