Scientists at Nanjing University of Aeronautics and Astronautics in China have succeeded in building a new floating device for generating electricity from raindrops, which uses natural water as the main part of its structure.
This innovative design reduces weight by up to 80% and manufacturing costs by up to 50% compared to traditional models while providing similar electrical output.
In this system, water simultaneously plays the role of the base of the structure and the conductive electrode and is capable of producing a voltage of about 250 volts per raindrop.
The new floating generator is highly durable and performs stably under various conditions such as temperature changes, salt concentration, and even polluted lake water.
The prototype, measuring 0.3 square meters, was able to simultaneously light up 50 LEDs and charge capacitors for small electronic applications.
This invention could have wide applications in rainy areas and marine environments and help develop clean energy.
