Forget water sprinklers — this 'infra-sonic' firefighting system from former NASA engineers promises to kill blazes using just sound waves
Fires are typically tackled using sprinkler systems and fire extinguishers across homes and larger buildings, but Ohio company Sonic Fire Tech is testing a fire-fighting system with a difference: it uses sound waves rather than water or chemicals.
The immediate benefits are obvious, in that people and properties don't get drenched at the same time as the fire is put out. There's another advantage too, because unlike water, sound waves can tackle grease fires — a type of blaze that's increasingly common.
Former NASA engineers form part of the team behind the "acoustic fire suppression technology", and Sonic Fire Tech raised $15 million in funding earlier this year, CNN reports. So is it the next big thing in fire defenses? These are the details.
How the technology works
The overall trendfor fires in the US is, thankfully, downwards. However, while there are fewer fires than there were 40 years...
