What if Innovations - Shell Ideas360

What If an old fridge could be a new water supply?

As demonstrated by 2013/14 winning idea Skywell, harvesting water from air has real potential to help millions of people around the world.

Another idea that addresses the same issue has been recently developed by professor and student collaboration Dr. Amin Al-Habaibeh and Joe Wild from Nottingham Trent University in the UK. Their innovative idea demonstrates how thinking about an existing product in a new way can lead to a simple but effective idea that could change the world.

What is the issue?

Access to clean drinking water is still an issue in many developing countries.

What is the idea?

The idea involves up-cycling old refrigerators that would otherwise go to waste and or landfill.

How does it work?

These modified fridges work by using reclaimed computer fans to draw humid air into them and then passing that air through a cold copper tube. The whole thing is also capable of being run on solar power.

What is the solution? 

By extracting water from humid air, this idea gives people who do not have sufficient water to survive – enough to meet their everyday needs. Once extracted, minerals can be added to the water to ensure it has the right balance of nutrients for the human body, addressing health issues caused by water shortages.
