"DARPA was on the case in 2012; and a search of the scientific literature reveals dozens of researchers investigating the idea. One startup now claims to have cracked the problem. Sonic Fire Tech has built an acoustic fire suppression system that doesn't just extinguish flames; it that might also protect homes and other buildings from wildfires. The startup has raised a $3.5 million seed round from investors, including Khosla Ventures and Third Sphere."
"Bruder had worked for NASA, where he focused on heat and acoustics. "This is kind of a new age founding story," Bruder, the startup's CEO and CTO, told TechCrunch. Bruder was intrigued with Thomas's idea and set about building a prototype. "I got a subwoofer and some parts from Home Depot and AutoZone and said, 'Hey, let's see if we can do any better than other people had,'" Bruder recalled. "We knocked a fire out from seven feet in my driveway.""
A decade ago a viral demonstration showed that a subwoofer can snuff out a fire. Researchers and organizations, including DARPA, have investigated acoustic fire suppression. Sonic Fire Tech claims to have built an acoustic fire suppression system that can extinguish flames and potentially protect homes and other buildings from wildfires. The startup raised a $3.5 million seed round from investors including Khosla Ventures and Third Sphere. U.S. wildfire losses can reach $424 billion annually and have prompted insurers to decline renewals in heavily affected regions. Founders progressed from driveway subwoofer tests to prototypes and shifted development toward lower frequencies.
