Today we will take a little dive into the world of self-sustainability and we will learn how to create fresh water out of thin air.
Sounds impossible? Well, it’s not.
The lack of water has been and still is a big issue around the world.
Just look at some places in the Sahara Desert where they have little to no water, and every day is a battle for survival.
Aside from having no rivers, there is also little to no rainfall annually, so growing anything is also nearly impossible.
You must be thinking, how is this possible?
How can we create water out of thin air?
Well, as a matter of fact, researchers from MIT, working side by side with their colleagues in Chile are working on developing a device that is pulling water out of the air, directly from ordinary fog.
As a matter of fact, this is not something new.
This technology already exists in 17 nations already, but MIT is working on perfecting it and increasing the efficiency and pace at which water is generated.
So, how exactly does this work?
The structure of the fog harvesting system is not really that complicated. It consists of a vertical mesh, similar to a tennis net, but bigger.
The material of which the mesh is made of is directly impacting the amount of water that we can generate.
Existing models are currently made of woven polyolefin, which is a plastic that is really cheap and you can find it almost anywhere.
With this mesh, we can extract only two percent of water from the fog, but with the latest materials and technology which is being used by MIT, we are getting close to ten percent.
Considering the fact that it comes only from one mesh, you can scale this really well if you choose to use multiple meshes.
Below are two videos which show the difference between the current technology used and the one used by MIT.
We can clearly see how superior this new technology really is, and I think that this is just the beginning.
In the future we will have much better technology available, which will give us the possibility to provide clean water for everybody around the world.
Clean water should be available to all human beings, and shouldn’t be a luxury for those living in developing countries.
Also, researchers from MIT have figured out that by modifying the size and structure of the mesh, you can also increase the efficiency of generating water.
Detailed experiments done in the lab have shown that the best performing mesh is made out of stainless steel with a size of approximately three or four times the thickness of a human hair.
There are other factors that influence the amount of water that is being produced such as: the size of the mesh that is being used and the density of the fog.
Meaning that in some places you can generate even more liquid if there is heavy mist and you also have a bigger mesh which allows a bigger conversion.
At the moment, researches in Chile have installed numerous meshes across different foggy areas around the country.
Large mesh structures with hundreds of square meters which are constantly generating water from thin air.
They consume no energy, they are really inexpensive to make and they only need a little cleaning from time to time.
With that being said, my personal opinion is that this technology is clearly revolutionary and, if done correctly, this research has the potential to provide clean and drinkable water for the whole planet.
What are your thoughts on this? Are you living in an arid region of the country where water is scarce?
Would you challenge yourself to assemble such a device?
