Home / Computers/technology / News / Video: Engineering Student Invented A Machine That Produces Water From The Air


An Indian engineering student has invented a machine that can turn air into potable water. Known as the DewDrop, the machine can produce nearly 2 litres of water an hour. Many people in developing areas of the world still do not have access to clean drinking water and an unacceptable number of people die every year from problems associated with consuming dirty water.

The DewDrop was invented by a 22-year-old Indian engineer student, Jawwad Patel. The DewDrop converts the atmospheric moisture into potable drinking water, it is basically a bottle which just fills and refills itself on it own. The machine sucks air using a fan, filters the dust in the air, condenses the moisture using the Thomson and Peltier effect, then mineralizes water and stores it for drinking. It's a 3D printed device that weighs about 900g, which in essence makes it easier to travel around with. The DewDrop is powered by a 12V 6000 mAh Li-ion battery and can generate at least 1.2l/hr of water in desert-like areas, claims Jawwad Patel.

Patel has also devised an interface to control the operation of the device which includes sensors which detect humidity, temperature and other factors. Patel is currently working on the next version of the product in which he is planning to incorporate a solar cell to power it and also provide the user with the choice of or cold water.

Have a look at the video to learn more about the DewDrop.
