A 24-year-old boy from India, Jawwad Patel has invented a device which can fetch water for you, from the air. This comes after the many parts of the country have faced the problem of water shortage even after the monsoon season.
Currently, India is experiencing drought in many states due to increasing water problems. Major cities like Chennai, Banglore, Jaipur, Aurangabad ran out of the water after the heavy heat experienced during the summers of 2019. However, even after the whole monsoon season, cities do feel the need for water management.
To deal with this problem of the water crisis, many organizations, individuals and agencies have been working on developing sustainable resource management techniques. In a similar run, a 22-year-old Indian engineering student, Jawwad Patel has innovated a device with the help of 3-D printing which can convert the dew drops into the water.
India water shortage is critical but nature’s hydrological cycle ensures that there is an abundant quantity of water present in the earth’s atmosphere. It is present in the form of water vapour everywhere & anywhere on the earth. This piece of fact triggered Patel’s thought process and he ended up devising a ground-breaking invention.
Patel’s invention named ‘Dewdrop’ is a 3D printed device. The speciality of this device is that it can convert atmospheric moisture into potable drinking water. The device is not much but just a bottle which just fills and refills itself on its own. The process of ‘Dewdrop’ device is that it sucks air from the atmosphere using a fan then condenses moisture using Thomson and Peltier effect. Due to the process, the water vapours present in the air gets converted into the water which is then mineralized and stored in a bottle for drinking purpose.
The device weighs around 900g, which can be carried around anywhere easily. It is powered by a 12V 6000 mAh Li-ion battery and can generate about 1.86litre of potable drinking water per hour. Further while describing the use of the device, Jawwad told that Dewdrop can generate at least 1.2llitre/hr in desert-like places.
Apart from devising Dewdrops, Jawwad has worked on developing an interface which controls the operations of Dewdrop and includes sensors which help the users detect the presence of humidity, temperature and other factors.
On being asked about how did this amazing idea came to his mind, Jawwad tells that idea of fighting water crisis with a device came to his mind when he once visited Latur, a small town in Marathwada region of Maharashtra. The area is arid and drought-affected. Looking at the situation of the people in the region, trying to fight the water crisis and surviving without water, he felt the immense need to work on the situation.
Jawwad’s device will be very useful for such people who are living in such arid regions. Further, it is of great use for people who trek in mountains, camp in deserts, go for a desert safari, go fishing in the sea, work in mines or work or live in a remote area.
Further, the device will not only help convert vapours into the liquid, but the inherent mineralisation process will give you clear fresh drinkable water. You can carry the device with you everywhere, thus saving you cost of buying packaged drinking water, thus eliminating plastic usage at the same time.
While currently, a basic conceptual design has been developed, Jawwad is now working on devising new features for condensing equipment. He is thinking of adding solar power to ‘Dewdrop’ by adding solar cells. Thus, the user will have the option to choose whether they want hot or cold water.
Apart from devising ‘Dewdrop’, Jawwad is well known for his other innovations which include smart lock, smart helmet, smart irrigation system, solar car, global and a quadcopter. He has received more than 50 awards from around the world for his innovations and is a TEDx speaker. You can know more about him and his work, here at his official website.
