Also, if you keep reading, it talks about research in 2022.
>The prototype already weighed 20 pounds, and in a real firefighting scenario, lugging around a heavy, power-hungry device could be a dealbreaker.
Too heavy? Unlike, I don't know, literally any other fire fighting equipment?
Anyway, it's clearly a silly curiosity and not a serious fire fighting tool. Maybe there is some undiscovered efficient waveguide modified systems that magically puts out forest fires like a wave of a wand but a amplifier and a speaker attached to a tube isn't it.
