However, I wouldn't limit this to being a "genius" thing -- there may actually be something significant to being able to apply knowledge and patterns in one or more field to a seemingly unrelated field, and people who tend to be interested enough to learn and think about a lot of different fields in depth have a better base of mental abstractions for inventing in a new field, even if they don't score ridiculously high on an IQ test.
Note that this is just a general rant -- re: the article, I don't think the pitch is particularly interesting or noteworthy.
