Developing nations are often the recipients of used, donated baby incubators, as new ones cost about $40,000 each. Often lacking either the technicians or the parts to fix them, however, most of the incubators don't actually work. Enter Jonathan Rosen of Boston University's School of Management, who's ingeniously devised an incubator out of the very abundant Toyota 4Runner. The device is cobbled together using headlights as the heating source, the filters for air purification and the door alarm for emergency notification. The resulting incubator costs about $1,000 to make and can be repaired by auto mechanics, which is obviously good news for hospitals in need. The bad news? Dr. McDreamy's in the garage, "fixing" your car.
