Scientists have found a way to generate electricity from rain

A new energy source has been developed that will allow lighting systems to remain operational in rainy weather.

As reported by BAKU.WS, this method is described in the journal "ACS Central Science".

Engineer Xiaolin Soh from the National University of Singapore noted that "rain contains an enormous amount of energy" that can be converted into electricity. The technology developed by scientists is based on the principle of electric charge separation. This occurs on the same principle as static discharge - for example, when you feel an electric shock when touching a metal surface after walking on a carpet.

During the experiment, water dripped into a 2 mm wide tube (approximately the size of a grain of rice). Thanks to the special rotational flow created in this tube, it was possible to obtain more energy. The rotational flow, unlike a constant one, repeatedly enhances the separation of electric charge - resulting in 100,000 times more energy being generated.

As strange as it may sound, these drops, upon reaching the end of the tube, fall into a stainless steel container. A wire connection is established between the tube and the container. Thanks to the water flow from four tubes just 32 cm long, enough energy accumulates in 20 seconds to continuously power 12 LED lamps.
