DewDrop Water-from-Air Condenser

Did you know? By 2025, an estimated 1.8 billion people will live in areas where water scarcity is prevalent. This is concerning, but fortunately, not unsolvable. In fact Jawwad Patel, a 22-year-old engineering student from Hyderabad has designed a 3D-printed apparatus which can 'create' water from air. He is the first person from Asia to do so. The water apparatus produces pure drinkable water with the help of computerized sensor interface with UV filter. In an hour, the device can extract nearly 1.8 litres of water from air. Called 'Dewdrop', this device uses the moisture in the air to create the water. It is also not Patel's first attempt at creating a novel device. He has previously created a smart helmet, which will not let you drive if you are drunk. He has also been nominated for the National Youth Award 2015-16 and Dr APJ Abdul Kalam Excellence Award 2016.

The product comprises a smart condenser, connected to an onboard computer and sensors. The apparatus has a fan that sucks the thin humid air from the atmosphere and transfers it to the smart condenser. It then converts the thin humid air to liquid water under the dome of a computerised sensor, with respect to the atmospheric parameters. The water thus produced gets passed through various semi-permeable membranes to wash out the dust and other unwanted things.

After the process, the water gets UV-treated which kills all the unnecessary microbiological activity and germs. The water then gets mineralised and finally stored in the tank attached to it. It can produce pure and healthy water even if the air is polluted. I have been using this water for the past 2-3 weeks and I'm still alive. The device cost him more than INR 12,000 (US$180) to develop. Once he starts commercial production, the cost can come down to just INR 2,000 (US$30), he adds. The Engineering student is getting hundreds of calls from the US, UK, Malaysia, Switzerland, Saudi Arabia, Dubai, Oman, Russia and Qatar for his revolutionary product.
