A constant pulsed laser beam sent from the skies over California to the skies over Denver may create a continual static field and draw of vapor around a fire. Think of a wildfire as only able to burn where humidity is very low. All we need to do is create high humidity to kill wildfires. Lasers would appear to be a very good solution. emailed this to Cornell: 'firstname.lastname@example.org'
(If you don’t think vapor will travel upwind from Denver to Cal try pulling the vapor in from the ocean, from the north or south, or straight up from the ground upwind of the fire.) But something tells me you’ll find stronger static force by drawing against the wind.
