Japanese researchers have successfully used drones to trigger and capture lightning, marking a significant step toward harnessing natural electricity as a renewable energy source.

A Spark of Innovation

The Nippon Telegraph and Telephone Corporation (NTT)conducted a series of experiments between December 2024 and January 2025 in Hamada City, Japan. The team deployed drones equipped with lightning-resistant cages and conductive wires, launching them 300 meters into stormy skies. By monitoring electric field fluctuations, the drones were able to trigger lightning strikes, safely channeling the energy to the ground.

Remarkably, despite the immense power of the lightning, the drones remained operational, demonstrating the effectiveness of their protective design.

Implications for Infrastructure and Energy

Traditional lightning rods have limitations, especially for structures like wind turbines and stadiums. NTT's drone system offers a mobilesolution, potentially safeguarding infrastructure by directing lightning away from vulnerable areas.

Beyond protection, the ability to capture and potentially store lightning energy opens new avenues for renewable energy research. With approximately 1.4 billion lightning strikes occurring annually worldwide, the potential for energy harnessing is immense.

Looking Ahead

NTT plans to refine this technology, focusing on improving lightning prediction accuracy and exploring energy storage solutions. The successful demonstration of drone-induced lightning strikes not only enhances our understanding of natural phenomena but also paves the way for innovative approaches to energy generation and infrastructure protection.
