title_body: Would it be possible to inductively recharge a drone battery? Regular drones can only fly around 15-30 minutes before the battery runs out, which is annoying.
  Newer smart phones use inductive loading, so it is possible to load a battery through such a field.
  Super capacitors can be loaded in a very short time with high energy levels. (side question: are those used in drones?)
  
  Would it be possible to get a drone close enough to a charge point to load the battery in flight? If yes, how close would that be? How long would it take?
  Would it be possible to build a loading station with this principle, lets say to put it on my roof?
upvoted_answer: Given how close you would need to be to the charging system, it makes little sense to keep flying rather than simply land on a charger.
  The question then becomes if the inductive power transfer scheme is worth the trouble vs having some sort of electrical contacts, possible with some kind of cam-driven capture in the base.
  On the one hand a wireless power transfer scheme is weatherproof and may require somewhat less positioning precision; on the other, it adds weight to the aircraft, and a lot of complexity.
