In rural areas of India like Asam, Mizoram, Arunachal pradhesh where it is moist for most of the time of year and very suitable atmosphere for dew formation.
This device can eliminate use of water purifier to a certain level.
Dew is nothing but water in its purest form. When in atmosphere with high moisture content, a temperature around a specific surface falls below the dew point of water. There are water droplets accumulated on the top of that surface. This is usually seen when a cold water is kept in a glass or early morning atmosphere on leaves. [1]
So if we could find a way to collect this dew, we would probably eliminate need of water purification. There are many places across the world where it stays humid throughout the year and it would be a huge help to community if we provide something like this to them.
Dew point of water is 15*C which is easily achievable even by simplest techniques.
Actual Dew collector commercially available is shown below
The design of most of the dew collectors are very simple and is something which can be done using 3D printers very economically.
In this device to keep the temperature below 15*C, I have used the aluminium foil which stays very cool when kept in moderately cool atmosphere.
A cloth provided on the top has to kept wet at start to initialize dew forming process. This will reduce temperature of foil and keep atmosphere near device cool.
Once dew formation process starts, it will keep the cloth wet and go on for long duration of time.
Technical Specifications and Assembly Instructions[edit | edit source]
Print the flask as provided STL. #Supports needs to be generated to print the funnel. Once you are through with the printing, wrap aluminium foil on top surface of funnel and attach your piece of fabric on top of funnel as shown in figure
