I've fleshed out the details. It's not quite realistically feasible today, but this should be available in 10 years.

The biggest hurdles to overcome are:

-Creating the flight management software

-Networking 260,000 devices with wifi technology

-Getting 5-6 MWh into the air to charge these 260,000 devices each hour.

-Battery life expectancy.
