Integrating Inductive Charging Capacity into Hybrid Electric Drone Vehicles and Service Facilities

Integrating Inductive Charging Capacity into Hybrid Electric Drone Vehicles and Service Facilities
As drone aircraft become ever more present on the frontlines of modern warfare technological developments of the underlying logistical capacity will need to be (developed?) augmented to ensure our Nation’s Warfighters are receiving maximum benefit from the tools provided to them. 
Ok I should stop trying to sound sophisticated, unfortunately I have no statistics right now on how having aircraft idling on an airfield impacts their ability to rapidly be deployed for long duration missions.

The intent of this proposal is to investigate the potential productivity gains stemming from integrating an inductive charging system into the airfields and roads of facilities using drone aircraft. 
Technical Questions:
*What is the trade off with installing this system, both in costs and changes in vehicle flexibility?
                For drone aircraft does it allow for more rapid deployment?
                For non-combat vehicles, would this allow planes to utilize local power as opposed to idling the aircraft’s engines?
                                -is the rate of energy transfer great enough
                                -accounting for several variables, do the considerations of energy needed for idling make inductive transfer make sense
                                                -added weight of transfer system
                                                -emissions savings
                If an airplane’s propulsion system is hybrid electric, could the inductive energy system provide supplemental power for takeoff, hopefully minimizing the size of the electrical generators.
-Can the 60 cm maximum transmission distance be overcome?
                                -what efficiency tradeoffs exist when distance between source and drain are varied?
                -how much base load draw occurs with no recievers?
                -potential for EM interference both for communication and sensing?
                -while offsetting the potential for a percentage of fuel explosions, what are the risks to personnel that stem from these systems if they are accidentally exposed
                -operational envelope in hot environments
               -cost for installation
                                -can inductive panels be produced, allowing for rapid assembly and break down

                -impact on mission flexibility for nuclear powered vessels
                              the book Wired for war talks about  the increased volume of air power that could be supplied by utilizing drone aircraft on aircraft carriers to the exclusion of manned aircraft
                             if aircraft are made able to passively re-energize on the flight deck, what is the impact on combat sorties during a given time increment
                             if there is an increase in sortie volume, would the costs make tactical sense

With respect to military applications, does an inductive power transfer airfield make sense in areas where larger scale energy infrastructure isn't available (this question is focused on airfields built for larger aircraft)

Alternative approach, integrating inductive energy transfer systems into smaller shorter range drone aircraft
ex, solar panels that can serve as landing pads at night for small quad copters/helicopters 

                      -using smaller aircraft with inductive charging, could the surfaces of convoy vehicles be transformed into roosting locations, allowing for smaller machines to move from vehicle to vehicle while minimizing exposure for the warfighter
