Sorry but this particular application fails the sniff test. Let me start by saying that I really wanted to be encouraging about this. The use of recycled auto parts to save infant lives is a truely noble gesture. Unfortunately the way the lives are saved may just be by ruining them. There may be a way to sterilyze the parts used without causing rust, oxidation, or corrosion but keeping them sterile would be a monumental if not impossible task. The second and more serious problem is that the method of warming the infants-pointing a car headlight at them is like stabbing them in the eyes. Neonates have undeveloped eyes that cannot regulate the amount of light that hit their retinas. They would be better off in complete darkness than a bright light on them. Their ears have a similar problem. They need silence to be able to develop smoothly and the open nature of the "junkyard" incubator does nothing to help this issue.
