The AirJet is a solid-state fan; it's small and silent, but can only dissipate about 5W of heat. So for the laptop, based on a Samsung Galaxy Book, they've included four AirJets. That's still half the size of the regular cooling system in that laptop model, allowing them to increase the battery size for the demo.
@Aether I don't get the "doesn't require fan inlet holes" portion though - you have to dissipate the heat somewhere, it's either air or the machine itself?
