This is technology that not everyone is familiar with. Some questions people want to know are surely:
1.) What makes it safe? Is it that the beam itself is harmless? Harmless for long term exposure, too? Or is it that the beam isn't harmless, but the system has systems in place to break the beam if obstructed?
2.) Will other technology be affected? Would drones, etc, interacting with the beam be adversely affected?
3.) HOW is this relatively unaffected by distance? So far I've heard you say that it isn't impacted by the atmosphere, but I think people are still curious to know more.
4.) How is this not impacted by rain/humidity? You linked an article regarding water not absorbing radiation, but didn't address the subsequent claims regarding refraction.
The point is. This is a technical place, please answer some of people's questions and stop just dismissing everyone as ignorant skeptics.
I'd imagine they'd never get approved blasting 400w per kW erratically.
We are using a strictly point to point collimated beam that is expected to meet nothing but clear air. It shuts down if/when any transient object is about to enter the beam path.
Also, don't forget that the important figure you should be looking at is power density rather than total power
You also claimed it's unaffected by rain.
Which is it?
Rain will trip the laser screen, as will fog.
Ergo, this will only work in clear air. Rain and fog will shut it down.
