Microwaving air is a really bad idea – you end up with lots of nasty NOx compounds
Does it generate more NOx than a kerosene powered turbojet?
While an interesting question in itself it seems pretty much moot. 5 MWt at 426 degrees C isn’t going to move much air by heating. Even times 20… assuming you could somehow duct the air past the FF cluster…
… but an FF-powered fanjet could have a sideline in de-icing runways while waiting for takeoff clearance… 🙂
