DROP BY DROP
Royal College of Art design graduate Pratik Ghosh, thinks we should all have access to clean drinking water - and that emulating nature's filtering process may offer part of the solution. It looks like a terrarium, acts like a "mini-Amazon rainforest" and it filters water. Frankly, this home water purification system is so pretty that we were sold as soon as the first images graced our screens. Now, let's have a closer look.
Called Drop By Drop, Ghosh's enclosed mini-ecosystem, incorporates one square foot of plants, plus a pump-activated vacuum system that uses water pressure, transpiration, evaporation and condensation of water to produce about three-quarters of a cup of purified water a day.
Less than a cup? Not very much. But now imagine this prototype being scaled up to cover residential roofs, of about 800 square feet on average. By adding a Drop By Drop system, such a roof installation could potentially purify about 35 gallons of potable water within 12 hours of daylight.
Though just a prototype for now, bio-inspired concepts such as Drop By Drop could be one effective way to tackle some of our most pressing environmental problems, whether it's water, our food systems, or how we build our buildings.
Now excuse us while we imagine the future arial shots of our cities - not to mention how beautiful the small prototype would look in our homes and office spaces...
See how it works here.
