No "erratic blasting" intended :) this is NOT like a strong WiFi.

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

> expected to meet nothing but clear air.

You also claimed it's unaffected by rain.

Which is it?

He claims there is a laser safety screen that cuts the beam off if it is tripped.

Rain will trip the laser screen, as will fog.

Ergo, this will only work in clear air. Rain and fog will shut it down.

In New Zealand, of all places, that's going to make this technology useless.
