What if we used the wing tip vortices from a heavy jet airline taking off to power up the run way lights? At three minute separation, the runway lights could hit a peak output just in time for the next landing aircraft or the next one to take off. This would be most excellent at O'Hare, LaGuardia, LAX, Memphis during FedEx operations, etc. Also good for military operations. These aircraft generate a lot of wind on take off and climb out and that wind came at an expense of power to make the thrust and create the lift. We should never waste power. To learn more:

Now then if these vortices are enough power to rip apart a small aircraft or cause an aircraft to crash, then surely we can use this with pop-up wind generators of the runway in the direction of cross wind to collect it? This means that aircraft operations can run at a maximum even if the power grid goes out and the airport is forced into auxiliary power.
Flight operations and safety integrity must be maintained at all times. An even better idea is to use rotorcraft in battlefield and rescue operations to create power. when landing the aircraft spins flat ceiling fans inside of flat boxes laid upon the ground to power up the entire field operations. The force of the air coming down spins the flat generators which wire the electricity to the nearest mobile command post tent, or module which will be needed to run air conditioning units or an array of other very important systems. In this case it would not be the vortex of the blades but the pushing down pressures.
If the Osprey at certain angles loses its lift and air flow to the rotor blades/propellers, then we know that the airflow both in and out must be very significant. The ground effect in effect could power up the important systems, which affect the needs of the rescue crews, search parties, fire fighter outposts or military operations. Just some thoughts on conservation of power. Never waste energy, which has already been bought and paid for.
