Energy from the rain: a revolutionary discovery paves the way for rain panels that can be placed on roofs in the same way as solar panels. A new method for collecting, storing and utilizing the electricity produced by raindrops could be a potentially revolutionary breakthrough in the field of energy harvesting. This discovery could lead to the development of rain panels that can generate electricity on rooftops. Until now, attempts to generate energy from rain have faced insurmountable technical hurdles, but researchers now say they have found a solution that could make rain panels as popular, if not more so, than solar panels. Engineers have long considered harnessing the energy produced by rain, and this technology is already being used in hydroelectric power stations and wave energy harvesting systems, where the movement of water generates electricity. The main problem was that the amount of energy produced by individual raindrops is insignificant. A similar approach to combining individual cells and achieving higher performance, used in solar cells, did not lead to the desired result. However, the researchers presented a solution that seems to bridge the so-called coupling capacity problem, and they create practical rain panels that produce a sufficient amount of electricity. The research results, published in the journal iEnergy, look promising and offer a new approach to organizing individual cells into a bridge-like array that enables energy harvesting and storage. In summary, the research team focuses on the optimal design to make rain panels a practical alternative or complement to solar panels. Zong Li, a professor at Tsinghua Shenzhen International Graduate School and one of the inventors of the pioneering discovery, commented on the discovery with the following words: “The results of this study provide a feasible system for harvesting energy from raindrops in large quantities.”
