OK, you got me there. *wipes egg off face*
When I was in eleventh grade my physics teacher told me people had experimented with self-sustaining dynamos for decades and that they don't work because they violate the second law of thermodynamics. I've learned about thermodynamics since then and can see clearly how it relates to the idea. I've learned about the self sustaining dynamo theory, how it works in clouds and cores, but never seen any evidence that it's true. No matter what experiment people run the process can't be recreated. Is that geophysics textbook going to tell me any different?
