"laser light is beamed through the fiber optic cable and converted into electricity at the aerial platform"  ....


Amazing if its possible than is it possibel it doing without an optical cable using direct laser beam ? if yes! a revolution of wireless power tranmission is at the door step!

Anyone would like to discuss this  ...

It is just a design content entry... at this stage at least

  sir, its a seed...if all went well it may become a fruitful tree.... , I am keen to hear my engineer freinds, that what are the technical challenges in this assumption?

Wow!
It can remain aloft and stationary indefinitely! COOL! 

Just found a video of 'laser power beaming technology' being demonstrated (on a micro-helicopter). The video is presented by Tom Nugent, president of LaserMotive.
Here's a link to the page:

The only challenge i can think is the weight of the cable..............longer the cable -- more the thrust. more the thrust -- heavy the motor....
