Japanese researchers have successfully triggered and guided lightning using specially made and protected drones, marking a world first in weather control technology.Japanese researchers have successfully developed a drone system to catch lightning and make power in a world first in weather control technology.
The project, led by Nippon Telegraph and Telephone Corporation (NTT), aims to improve public safety by reducing damage from lightning strikes, which

Tests were carried out in the mountainous region of Hamada City, Shimane Prefecture, between December 2024 and January 2025. During the trial, a drone was flown into a thundercloud at around 300 metres high. Once a specific electric field level was detected, researchers activated a ground switch connected to the drone, which triggered a lightning strike.To protect the drone from being destroyed, engineers designed a special lightning-resistant metal cage.
This shield helped direct the lightning�s current away from sensitive parts of the drone, allowing it to remain stable even after being hit. The cage has been shown to withstand five times the strength of a normal lightning strike.
The technology uses electric field fluctuations to attract lightning and guide it to a safe location.
The aim is to eventually use networks of drones to protect cities and key infrastructure, especially areas where traditional lightning rods are not practical, like wind turbines or outdoor stadiums.
This breakthrough could help scientists better understand how lightning forms and how to safely manage it. Current methods for lightning protection are limited, and this drone-based system offers a more flexible and proactive approach.
NTT worked with tech firm Fujitsu to develop the system. The experiment featured two key technologies, lightning induction using electric field fluctuations to attract lightning to a drone, and a specially designed lightning-resistant cage that prevents drone failure even under direct strikes.
Future plans include deploying these drones across urban areas to guide lightning away from danger zones. There is also interest in exploring whether energy from induced lightning can be safely stored and used.
