Generates electricity from toilet water

Recently, Korean scientists have figured out how to harness the power of toilet water to generate electricity. In the future, this application can also be extended to use with rainwater, waves, river flow or even drops of water.

Science at the Korea Institute of Electronics Technology (KETI) and Seoul National University took advantage of an attribute of dielectric materials that could generate electrical current when it was introduced into water. They have created a converter that converts mechanical energy from the motion of water into electricity.

In the video above, we can see different situations, in which the movement of water produces a green LED shining power, even a single droplet also has the power to generate electricity. . According to lead researcher Youn Sang Kim, two dielectric layers form around the dielectric material when it is embedded in water. When the dielectric becomes wet from water, electricity is generated from the electrodes. A droplet of 30 microlitres can also generate enough power to brighten the green LED.

The research team hopes that their research results can be applied to daily life. The converters can be mounted on windows, roofs and toilets. In such locations, rain and running water on the wall can also be used to generate electricity.
