DelivAir uses drones to deliver to people, not physical addresses

Recipients need to be present at an address, for example. Now, though, Cambridge Consultants -- the team that brought us intelligent bins and Renaissance doodling -- has developed a drone delivery system that'll get you your stuff anytime, anywhere, in a matter of minutes. Let's imagine you're out having a nice walk in the middle of the countryside when you start feeling peckish. Using Cambridge Consultants' DelivAir app, you'd place an order for a snack, and the delivering drone would use GPS and your smartphone signal to navigate to your location, periodically asking for location updates during its flight, until it's within visual range. Once it arrives, you point your mobile phone flash LED to the sky, where it'll blink a coded pattern to let the drone know it's delivering to the right person.
