Laser Fire-Fighting System

A group of Texas-based inventors was recently granted a patent (No. 12,415,107) for a fire-fighting laser system. You mount the laser on your roof and it zaps embers before they can reach your house. I'm doubtful this would work. But I'd love to see a trial of it in action. From the patent: A system for neutralizing embers is disclosed. The system includes a laser turret with a sensor array and a laser emitter configured to dispense laser energy. The laser turret can also include a control system configured to move the laser emitter. The laser control system can receive information from the sensor array and sending signals to the control system to move the laser emitter. Using these features, the laser control system can select an incoming ember based on a thermal signature associated with the incoming ember, and the laser control system can issue commands to the control system to direct the laser emitter towards the incoming ember, and the laser emitter can direct laser energy at the incoming ember. The system can also include provisions to track an ember and determine if an ember has been depleted of fuel.
