That expensive it would be best if it didn't fail so easily. They shouldn't have vampire drain and they shouldn't require such difficult revival. Also I'm pretty sure that it's readily possible to put electric motors in the wheels of planes such that they can move themselves. Both low speed torque and high speed spool up to not burn rubber for landing. At any weight class. Airliners shouldn't need push back nor fry their tires on every landing. Or shudder the plane. Just spooling up the tires might make it possible to land without anybody noticing.
Hub motors, of course the FAA would throw a temper tantrum but it could also be used for short takeoff (accelerate the airplane) and landing (spool the tires then apply deceleration).
@@vitordelima accelerating the plane would take real power so that's not as obvious. slow movement doesn't take much power and just spinning up the tires in the air doesn't take much either. Actually accelerating the plane would take car like power, that's big motors and big batteries. Not impossible but likely not worth it.
@@DanFrederiksenIt happens for a few seconds (so it doesn't use that much energy) and modern hub motors have insane power density, a similar idea was used in electric STOL systems which use auxiliary propellers and separate batteries. But this doesn't seem to be viable for bigger airplanes.
