This Student-Designed Ventilator Is 80 Times Cheaper Than the Norm

Babies born premature or sick are often completely reliant on a ventilator to stay alive. In many parts of the world that's a $40,000 machine that runs completely autonomously, but in developing nations it's often the child's parents--continuously squeezing a hand pump. It's a depressing image that inspired students at Brigham Young University to design a portable ventilator that costs just $500 to build.
