The new technology will harness the kinetic energy of falling raindrops. The energy from a single raindrop is enough to ignite a hundred LED lamps.
Scientists have long since considered the option of harnessing the energy of falling raindrops. A group of scientists from Hong Kong (a tropical region with frequent rainfalls) have made a breakthrough in this field. The researchers managed to create a generator that captures the energy of the rainfall: one raindrop can generate power up to 140 V.
The core of the device is a Teflon-covered electrode obtained through an alloy of indium and tin. This choice of materials is no accident: the alloy has a quasi-permanent electrical charge that increases as the raindrops fall. A second electrode is situated next to the first, and when it starts raining, the circuit is closed. The energy is then released.
This setup is not yet ready for practical use. Scientists are currently discussing ways to make the process easier to manage so that energy can be accumulated and extracted. If scientists achieve success in this field, the system can be easily scaled, which means that it will bring a lot of benefits to society.
