Sabre Runner writes to mention that a new British start-up, Aesir, has acquired the assets of a defunct drone company and is working on evolving a working model from several prototypes of "flying saucer" drones. "Aesir's first prototype, named 'Embler' [...] demonstrates the so-called 'Coanda effect,' where air speeds up as it 'sticks' to a curved surface. Aesir's drones take advantage of the Coanda effect to direct air down, away from the drone, boosting lift. Aesir doesn't appear to have any paying customers yet — and is reportedly bankrolled by a single investor."
