Infrasound waves stop kitchen fires, but can they replace sprinklers?

Infrasound waves extinguish kitchen fires in seconds, but replacing conventional sprinklers costs five times more per installation, making the trade-off steep. A single unit covers 100 square feet, 30% more area than the runner-up, yet the $2,500 average price per system is 80% pricier than traditional alternatives. This technology outperforms #4's fire safety solutions in speed but falls short on affordability, with researchers estimating only 12% of homes could justify the expense.
