Obsah:
- <p>Conventional electrical infrastructure fails as a single system under disaster conditions — loss of power coincides precisely with the moments when navigational guidance, emergency communication, and rescue operations most depend on it. Flood-related electrocution causes an estimated 300–500 deaths annually in India alone, and the absence of navigational visibility during nighttime rescue operations is a documented cause of preventable fatalities.</p> <p>This paper proposes a four-layer survivability-oriented electrical distribution framework for coastal urban infrastructure. Layer 1 provides normal overhead supply; Layer 2 provides underground clustered emergency distribution at 1.5-metre burial depth; Layer 3 provides ground-embedded ELV guidance lighting for navigational visibility under inundation; and Layer 4 provides a 72-hour autonomous LiFePO₄ battery failsafe. Every layer transition is triggered passively by voltage absence — no sensor, software, or human action required at any step.</p> <p>The paper introduces a Survivability Index (SI) metric applied to six real-world Asia-Pacific utilities, demonstrating that even Tokyo TEPCO scores below 25% of the framework maximum. Implementation barriers, regulatory pathways, lifecycle cost analysis, and retrofit feasibility across six infrastructure contexts are provided. Installation cost: USD 81,000–233,000 per km for full greenfield build; USD 31,000–83,000 per km for partial upgrade. This is a theoretical proposal; experimental deployment and validation are identified as future work.</p>
