I'm have a Masters in Aeroacoustics (acoustics + fluid dynamics) and work mostly on numerical simulations, so while I can see that for someone outside the field this can look like black magic, I am certainly not impressed.

I mean, what he did is he used a commercial CFD (computational fluid dynamics) software, created a model of the cabin and iterated through different air outlet geometries until he found one that improved the situation. It's a brute-force approach, which could be done even by someone without Masters/PhD level CFD knowledge (we have 1st year undergrad students working on that kind of thing in the university...).

It's cool that he used that for a problem that apparently is not getting the deserved attention, and he is 17 (!) but, at least in my opinion, other inventions competing for the price look much more impacting/life-changing. For instance:
