TOKYO, Jan 20 (News On Japan) - Satoshi Nakagawa, CEO of Tripod Design, has pioneered a groundbreaking technology called "micro energy harvesting," which collects minuscule amounts of electricity from a wide range of everyday materials, including soil, bread, water, and even fruits like tomatoes and apples.
This innovative approach involves inserting electrodes made of different materials, such as magnesium and carbon, into substances that contain moisture or ions. When these electrodes interact, a small electric current is generated, capable of powering devices like lightbulbs or even charging smartphones for extended periods.
Nakagawa has conducted extensive research, testing over 3,200 different substances, ranging from soil and water to construction materials and living organisms. Most substances, except for insulators like rubber or glass, have been found to generate electricity using this method. In one demonstration, a piece of bread and two electrodes successfully powered a light, showcasing the simplicity and versatility of this technology. In another experiment, electrodes inserted into park soil or tap water produced similar results.
The potential applications of micro energy harvesting are vast and transformative. Major corporations, including NTT Group, have taken notice and are exploring ways to commercialize the technology. Its uses span various fields, from powering medical devices and disaster response tools to sustainable energy solutions in space exploration. By generating power from easily accessible materials, the technology challenges the conventional focus on large-scale electricity generation, instead emphasizing the value of harnessing small amounts of energy from diverse sources.
Nakagawa’s work represents a significant step forward in sustainable energy innovation, with the potential to reshape global electricity consumption. As the technology continues to advance, it offers promising solutions for energy challenges in healthcare, disaster preparedness, and beyond, paving the way for a more sustainable and resource-efficient future.
