Water from thin air

A new start-up in India, named Kindle Ventures, is planning to use a technology that can make up to 20,000 litres of water a day out of thin air.

This game-changing, commercially viable Dutch technology uses the concept of condensation to turn air into fresh water. The technology can be used in any terrain – however back of beyond like many parts of India – provided the minimum temperature of the area is more than 15 degrees centigrade.

The company’s Chief Innovation Officer Gaurav Goenka has signed an MOU with Canadian owned Dutch company Rainmaker World Wide Inc, which holds the patent for this innovation.

The air to water unit uses a turbine that forces air through a heat exchanger where the air is cooled and condensation takes place. Lowering the temperature of air requires minimal energy. When the temperature falls below its dew point, water droplets will form which are then collected in the water storage compartment. The actual amount of the water than can be produced depends on the average wind speed, the ambient temperature and the relative humidity. The conversion process is applied via a patented “directdrive” turbine which uses compressors that generate heat.

This heat is then used to cool down large amounts of incoming air, which is displaced by using vents.

The technology does not need electricity. It can run with solar and wind energy. The company is planning to mount the technology and take it to states like Maharashtra, Bengal, Andhra Pradesh and Gujarat for demos to state governments.
