Ultra-thin batteries to power lifesaving ‘tsunami balloons’ for quick evacuation
SMRTR summary
Japan's Tohoku University developed an innovative tsunami warning system that automatically launches illuminated balloons 40 meters into the sky within three minutes of receiving satellite alerts, providing visual guides to evacuation shelters. NGK Insulators' ultra-thin EnerCera batteries power high-intensity LED lights inside the two-meter balloons, ensuring visibility even in darkness or heavy rain. This technology is crucial for Japan's Nankai Trough region, where 60+ municipalities face potential tsunami strikes within just 10 minutes of predicted megaquakes.
