Indian engineer, Jawwad Patel, has invented a small device, known as the Dewdrop, that is capable of producing two liters of water every hour from the air.
It is a relatively simple-to-create device, as it is just a container that constantly refills itself, using fans to bring in moisture from the surrounding environment. It filters the dust from the air and mineralizes the water as it’s being created. The water is condensed using the Thomson and Peltier effect.
Here it is
Though it produces about 1.86l/hr in humid environments, it can still create about 1.2l/hr in desert-like areas. It is powered by a 12V 6000 mAh Lithium-ion battery.
Advancements are being made to the machine that will allow it to be powered by solar panels and let the user choose if they want hot or cold water.
