Abstract
In today's world, where clean water is getting harder to find and we need more energy than ever, reusing leftover heat from everyday sources is a smart, green way to clean water. This project builds a cheap water cleaner that grabs waste heat—like from factory smoke stacks, car engines, or even solar panels—to turn dirty water into pure stuff through boiling and cooling.
We made it with everyday stuff: a metal heat grabber, a cozy boiling box that's well-wrapped to hold heat, and a cooling spot to catch the fresh water drops. The leftover heat warms up the yucky water in the boiler until it turns to steam. Then, that steam hits a chilly metal wall and turns back into clean water, without any salts, metals, or germs.
The whole thing is cheap to build, easy to fix, and super good at using every bit of heat, perfect for villages or small towns where fancy cleaners cost too much or are hard to get. Tests show that even warmish leftover heat (60–90°C) makes a good amount of clean water, so it's real doable for little groups of people.
This work shows how grabbing extra heat can make energy use smarter and help fix the clean water problem in a way that's kind to the planet and won't break the bank. It's a cool step forward for green tech and smart ways to reuse what we'd throw away.
