I always thought it would be cool if a company built a big bird's nest tower in cities that would host a bunch of flying drones. Then, consumers could rent the video-capture drones online to fly over approved areas, upon which the drones would return to nest for re-fueling. Think maybe you could subsidize the cost (possibly even make a profit) with the video data, or by streaming some feeds for the population to watch. Though have no idea of feasibility (FAA, equipment, real estate), I do like the idea of eyes in the sky for consumer benefit. Maybe something like this could be used for defense - giving population more awareness of airspace.
