Sonic Fire Tech technology uses low-frequency sound waves to drive oxygen away from flames, extinguish small fires without water or chemicals, and prevent damage caused by sprinklers in domestic environments.

Technology that fights fires with sound waves, without water or chemicals, has been patented by Sonic Fire Tech as an alternative to extinguish small-scale flames. The solution uses infrasound to interfere with combustion, driving oxygen molecules away from the fuel.

The proposal was created by Geoff Bruder, an aerospace engineer who researched thermal energy conversion at NASA and co-founded the company.

The initiative addresses the limitations of traditional firefighting, as water can be scarce or cause damage, and chemicals affect health and the environment.

How fires are extinguished by sound

Fire depends on heat, fuel, and oxygen. The technology emits low-frequency sound waves to prevent the fire from receiving enough oxygen and maintaining the chemical reaction.

Bruder stated that the method vibrates the oxygen faster than the fuel can use it, blocking the reaction. The company does not claim to be the pioneer in using sound against fires.

Infrasound solves an old challenge

The acoustic influence on flames was already known in combustion. DARPA studied the subject in the early 2000s, and academic researchers had been conducting experiments for decades.

Albert Simeoni, from Worcester Polytechnic Institute, told Scientific American that the challenge was to scale up the technology without sound effects. Sonic Fire Tech used infrasound, with waves of 20 Hz or less, inaudible and capable of traveling far.

Testing and residential use

Firefighters in San Bernardino tested a wearable device developed by the company. Sonic Fire Tech also offers integrated home solutions, triggered by sensors, to extinguish flames without wetting floors or damaging furniture.

Remington Hotchkis told CBS News that sprinklers are ineffective in grease fires and can spread the fire. The company says its system suppressed flames with autonomous detection, but the acoustics still only work on a small scale.

Testing and residential use

While an average building in London or New York takes three years to be completed, in China a 26-story tower went up in five days with about 100 workers, and the global modular construction market already moves US$ 95 billion per year.

A Chinese factory in Guangdong is assembling a humanoid robot every 30 minutes while Tesla, Figure, and Boston Dynamics still struggle to deliver 10 thousand per year.

Australia installs giant concrete structures on the seabed 800 meters from the shore to create an ocean intake for desalination that will draw in saltwater and produce 30 million liters of drinking water per day.

A public school student single-handedly created a machine capable of treating water for up to 50 people using only solar energy. It was awarded third place at one of the most important science fairs in the world.

Germany installed vertical solar panels on a lake in Bavaria, and the result broke conventional logic: instead of producing energy at midday peak, the plant generates more early in the morning and in the evening, exactly when families turn on appliances and factories are in full swing.

While communities suffer from water scarcity and the advancing desert, women in Morocco use nets high up in the mountains to trap fog droplets, fill reservoirs, and transport drinking water through more than 10 km of piping.

Chinese boats accelerate the collapse of fishing in Senegal, cause an annual loss of US$ 300 million, affect 1.3 million people, and help transform West Africa into the epicenter of 40% of the planet’s illegal trawling.

Super airplane Phantom 3500 advances towards its first flight, promising 60% lower fuel consumption, a windowless cabin, operation above 51,000 feet, technology validated by DARPA, and a billion-dollar order of 300 jets before certification.

With an updated oil-bathed belt, the 2026 Chevrolet Onix and Onix Plus arrive with discounts of up to R$ 23,000, fuel consumption of up to 19.7 km/l, a range of 866 km, a 115 hp turbo engine, and a 5-year warranty.

Switzerland dug a hole the size of two football fields to install the most powerful underground battery on the planet, capable of releasing 1.2 GW in milliseconds, storing 2.1 GWh, and costing up to 5 billion Swiss francs.

Mega dam of 2.1 km will store 2.9 billion m³ of water and benefit 70 million people, while the government tries to reduce the impacts of water scarcity caused by disputes over the Padma River after decades of tension in Bangladesh.
