I didn't RTFA, but what a lot of commenters seem to be missing is the concept of economy of scale. The great idea here seems to be that using "off the shelf", mass-produced car parts to create an incubator with equal functionality to that of a standard incubator saves a great deal of money. Plus, the car parts have been better tested and are apparently more reliable. So this is kind of like building a software system by combining lots of preexisting, well-tested components rather than custom designing everything in-house.

I think you mean that you couldn't care less, not that you could.

Sorry to be anal, but that's one error that's not going to catch on and become standard if I can help it.
