Cool, but I doubt it will be very efficient on swarms, and would it not be easy to protect a drone using some reflective material, or at least delay the impact of the laser on the drone?
Will never be available to the public, hell they are trying their best to get little 2watt lasers out of our hands.
As far as its intended use I think it's s great idea, don't forget that even though we are all safe operators with no ill intent a platform capable of being operated a few miles away with relative ease is dangerous in the hands of someone who means harm.
