The genius of the NeoNurture incubator, developed by university students in the U.S., is that it employs an underutilized resource (old car parts) to address a critical need: functioning incubators to nurture premature newborns. Headlights provide heat; a repurposed dashboard fan circulates air; a door-chime and signal-light assembly is rejiggered into an alarm system that alerts caregivers when things go awry with the heating mechanism. The device can even be powered from a motorcycle battery. Car engineers have nothing on these guys.
