Blue lasers did not burn Lahaina, Maui. That conspiracy theory sucked in a lot of otherwise smart people. But NOBODY figured in the amount of raw power it would take to get a laser thru 185km of atmospheric attenuation with enough burning power arriving on the ground to accomplish the ‘wonders’ of burnt Lahaina. Some really smart, and skeptical, friends and I figured the power needed is in the MEGAWATTS. It would take a nuclear power plant in orbit to drive such a laser.
Now… such weapons DO exist, but they are ground-based with a big powerplant backing them up.
Wind driven firestorms can, and do, make all kinds of strange actions that are just not intuitive to the standard mental image of a ‘big fire’. So people make up sh!t to explain what they do not understand. Ever seen a fire tornado? In one video of Lahaina I saw one house untouched while everything around it burned to the ground. And the house was NOT blue. The blue umbrellas were commercial grade heavy, and probably have a tag stating they are ‘fire resistant material’ as some local fire codes will require. And it all depends on how the winds whirl.
