This plant-based water filter works like a tiny Amazon rainforest

Designer Pratik Ghosh said Drop by Drop "is indeed a mini version of the Amazon."

Drop by Drop fosters transpiration similar to processes in the famous rainforest.

Drop by Drop filters greywater from home kitchens or even bathrooms.

The distilled water can become drinking water by adding salt.

A light in Drop by Drop sets off photosynthesis in the plant.

Drop by Drop is Pratik Ghosh's final year project at Royal College of Art.

The system requires little maintenance.

The prototype can currently filter one glass of water in 12 hours.

Too often, we take <a href="https://inhabitat.com/tag/water/" target="_blank">water</a> for granted. Civilizations have risen and fallen after exploiting water sources, according to <a href="https://www.rca.ac.uk/" target="_blank">Royal College of Art</a> (RCA) graduate student <a href="http://www.ki-kando.com/work/" target="_blank">Pratik Ghosh</a>. He designed <a href="http://www.ki-kando.com/work/#/drop-by-drop/" target="_blank">Drop by Drop</a>, a <a href="https://inhabitat.com/tag/plants/" target="_blank">plant</a>-based <a href="https://inhabitat.com/tag/water-filtration/" target="_blank">water filtration</a> system that explores more sustainable methods of obtaining water.
