Nokia, once a dominant force in the mobile phone industry, is now often associated with the word "fading." While its mobile phone business was acquired by Microsoft, the veteran Finnish company is still striving to showcase its innovative spirit and hardware capabilities. Recently, Nokia released an intriguing video on YouTube, highlighting its collaboration with the University of Southampton in the UK on a lightning charging project.
In the video, scientists demonstrated how they created artificial lightning with a voltage of up to 200,000 volts, successfully charging a Nokia Lumia 925 in just seconds. The experiment involved two conductors placed about 300 mm apart, where the lightning struck and generated a crackling sound. Remarkably, the phone, located less than 200 mm away, remained unharmed.
Neil Palmer, the lead scientist, explained that the idea of using lightning to charge phones came from Nokia itself. He emphasized that the Lumia 925's stable circuitry played a crucial role in handling the high current without damage. According to official sources, the process involves converting alternating current into a high-voltage current resembling lightning, then adjusting it to a suitable level for charging. Although the concept sounds simple, the challenge lies in controlling and converting this unpredictable energy.
Lightning, one of nature’s most powerful forces, has long been feared rather than harnessed. It causes billions in damage annually and is considered one of the top natural disasters. Unlike solar and wind energy, lightning remains underutilized due to its randomness and short-lived power. The voltage of natural lightning can reach up to 1 billion volts, far exceeding the 200,000 volts used in the experiment.
While the idea of charging a phone with lightning sounds exciting, practical implementation faces significant challenges. The technology needed to safely capture and convert such high voltages is still in early stages. However, Nokia sees this as a step toward future wireless charging solutions.
Chris Weber, Nokia’s vice president of sales and marketing, expressed confidence: “As one of the first companies to introduce wireless charging, we believe this trial could lead to a new era in mobile phone charging.†The experiment also highlights the potential of harnessing natural energy, offering hope for regions with limited access to electricity.
Though still in its infancy, lightning-based charging could one day provide a clean, renewable energy source. As Palmer noted, “This discovery shows that equipment can use the current in the air to charge—this is an important step in understanding and utilizing natural energy like lightning.â€
Despite the challenges, the vision of capturing and using lightning energy is both inspiring and ambitious. Projects like the Hydra Skyscraper, which aims to collect lightning energy to produce hydrogen, demonstrate the creative possibilities. But until the technology matures, lightning will remain more of a dream than a reality.
