#RoyalCollegeofArt graduate #PratikGhosh has designed a home #filtrationsystem that's powered by #herbs and #purifies #wastewater from the kitchen.
Drop by Drop houses plants under a glass dome. Pipes allow water to be added in to be purified, and later collected. The system is designed for #greywater – which comes from washing machines, sinks and baths.😐😐😐😕😕😷😷😷 A light within the dome triggers the plants to #photosynthesise and #transpire, so water is drawn through the roots and onto the leaves, where it enters the air as vapour.
A pump controls the system's airflow and creates a vacuum to further expedite #transpiration.
The moisture is then drawn out of the dome, and condensed to form purified distilled water – which can have salt added to make it suitable for drinking. Drop by Drop also releases oxygen into the room. "The proof of concept is indeed a mini version of the Amazon," said Ghosh, a student of the Royal College of Art's (#RCA) masters programme in Innovation #DesignEngineering. "It is a #biosphere wherein the five key factors necessary for efficient transpiration, namely warmth, wind, light, pressure and humidity, are maintained at an #optimumlevel." The designer set out to create a proof of concept that would be "beautiful yet provocative", designing something that's intended to be placed in the living area rather than hidden under the kitchen sink.
He recommends using herbs as they can be easily grown indoors for use in cooking, and add an enjoyable taste to the filtered water
