Going green can be done in many ways. I could go on and on discussing how to save electricity and be more eco-friendly but I’d like to focus on how you can do so right from your bathroom. You would think it’s only possible by conserving water and switching to LED bulbs but South Korean researchers devised a way for toilet flush systems to harness energy. It’s sustainable energy that generates electricity with every flush.
My water bill went up last month so I had to be wary of the water use in our household. I had to remind everyone of the two types of flush button. But with the new toilet flushing system, I’d be okay even with the frequent flushing. Why, electricity can be generated with every level pump when needed. Electricity from the system is good enough to power an LED bulb. No, it may not be big enough to power an aircon but it would sure help. Maybe someday it would be more powerful.
The transducer that convert mechanical energy into electrical energy from from water motion was developed by Seoul National University and Korea Electronics Technology Institute (KETI) led by Youn Sang Kim .
University of Freiburg’s Andreas Menzel explained the system: ‘The researchers have taken advantage of the contact electrification between a polymer and water droplets in motion to design a simple energy harvester’.
This is just the beginning. I know more similar sustainable energy source will be developed but for now, let’s be more active and expressive in showing our concern for the environment by opting for the ‘greener’ choices always.
