Innovation Explores the Potential of Lightning as an Energy Source and Marks a Pioneering Advance in the Use of Drones for Atmospheric Collection
Japan has just achieved an unprecedented feat: attracting and controlling lightning using drones. For the first time in the world, a system has been developed to guide natural electric discharges through flying devices.
The experiment, conducted by Japanese companies such as Nippon Telegraph and Telephone Corporation (NTT), was deemed a success and may open the way for unprecedented applications in public safety and energy generation.
How Lightning Induction with Drones Works
The system uses drones equipped with technology capable of inducing lightning. Engineers designed an impact-resistant cage, allowing the drones to remain functional even after being directly struck.

The race of humanoid robots in factories has truly begun, Hyundai announced that it will deploy more than 25,000 units of Atlas in its production lines starting in 2028, in a partnership that involves Boston Dynamics and training with Google DeepMind.

Russia wants to build new nuclear plants in Brazil and is negotiating an agreement with the Lula government to expand Rosatom’s presence in atomic energy projects, small reactors, and peaceful nuclear technology.
The technique is based on manipulating fluctuations in the electric field, something that occurs naturally in storm clouds.
These drones not only withstand the impact but can also safely guide the lightning. The metal structure of the cage serves to divert the electric current away from the drone’s internal components, ensuring flight stability even after the shock.
Goals Beyond Technological Innovation
According to NTT, the purpose of the technology goes beyond innovation. The aim is to help prevent damage caused by lightning in urban areas and critical structures.
Japan records annual losses between US$ 702 million and US$ 1.4 billion due to these natural events. Even with traditional protection systems installed, such as lightning rods, the risk remains high, especially in hard-to-reach locations.
NTT’s communication installations, for example, are part of the infrastructure considered vital. Protecting these points from atmospheric discharges is a priority for the company, which now bets on drone technology to achieve this goal.
Successful Test in Shimane
Between December 2024 and January 2025, the first successful experiment was conducted in the mountainous city of Hamada, in Shimane Prefecture. The test was conducted in collaboration with Fujitsu and was based on natural storm conditions.
During the experiment, a drone ascended to 300 meters in altitude on December 13, 2024. The action was coordinated with the electric field measurement using a terrestrial field mill.
At the moment the field reached a high level, a grounding switch was activated. This caused a sudden change in the electric field, resulting in a lightning bolt being generated and attracted by the drone.
This was the first documented case in the world where a drone was responsible for initiating a lightning discharge. The structure of the cage, combined with the controlled manipulation of the electric field, allowed the drone to remain operational even after the direct impact.
Technical Innovations Revealed in the Experiment
Two important advances were demonstrated in the tests. The first was the actual induction of the lightning, achieved by intentionally altering the electric field through grounding activation. The second was the resistance of the protective cage, which managed to withstand artificial lightning with intensities of up to 150,000 amperes. For comparison, this value is about five times higher than the average of a natural lightning strike.
The protective coverage of the cage was estimated at 98%. This structure can redirect magnetic fields and electric charges, preventing the drone’s core from being damaged. Even with the impact, the equipment maintained stable flight without critical failures.
In addition to demonstrating resistance, the engineers were able to time the grounding connection to generate lightning in a controlled manner, opening the door to new forms of operation in urban and industrial areas.
Future Applications and Energy Generation
The next steps involve the practical use of drones in metropolitan areas. NTT intends to use these devices to predict zones with a higher risk of lightning, induce lightning safely, and guide them in a controlled manner. The goal is to create an aerial defense network against atmospheric discharges.
Another goal is to explore the possibility of storing energy from the induced lightning. Although the process of capturing and converting is still in its initial phase, there is interest in transforming this energy into a usable source in the future.
The technology may also contribute to advancing research on lightning formation, a phenomenon that still presents many scientific gaps. The expectation is that the data collected will help clarify the processes involved in discharges and improve forecasting systems.
Conclusion: A New Frontier in Climate Security
The Japanese project represents a milestone in the attempt to understand and control one of the Earth’s most powerful natural phenomena. With drones capable of inducing and withstanding lightning, the country paves the way for more effective solutions in protecting cities, critical infrastructure, and even in energy use.
If the tests continue to advance, it is possible that in the future storms will cease to be merely a risk and become a technological opportunity as well. Japan has already taken the first step.
