oved the high tech analysis for future solutions.
On visits to L.A. I was impressed with the sprinkler water systems for lawns.
Idea.. Build resevoirs connected via boring tunnels to all residential areas. These will be under gravitational pressure.
Connect them to industrial sized sprinklers in residential areas. No machines,pumps etc to break down and just work when there is a fire.
This system could be connected to all fire hydrants too for the fire dept to access.
My idea would be to have the sprinklers high above the residential roofs on power poles if the area does not have underground electrical supply.
Preemptive sprinkling could be done when fire warnings go to red.
This is a cheap lowtech solution.
