My sustainable topic is the Altered nozzle. It’s a new tap which saves up to 98% of water. This nozzle atomizes the water to a fine mist. The secret behind saving up to 98% water are millions of small droplets that enlarge the surface of the water coming out. But if you want to fill a glas with water and you don’t want to wait 5 minutes for it to come out, you just have to rotate it and you will get a bigger water stream.
This project was financed on kickstarter in September 2016 and it’s now available on their website for 55$.
