Now, generate electricity by just flushing your toilet

We may soon be able to generate renewable energy from just flushing the toilet.

Researchers in South Korea have reportedly developed a method of harvesting electricity from the natural motion of water, ranging from drops of rain cascading down a window to a flushing toilet, Fox News reported.

The technology may eventually be used on surfaces outside of homes alongside solar and wind power-generating components.

The key behind the technology is an adapted transducer generated by the research team at the Seoul National University and Korea Electronics Technology Institute.

And while initial demonstrations have focused on small-scale applications, researchers believe the energy harvesters can "substantially inspire" new harvesting technologies from ambient energy sources.
