Polish nanotechnology scientists say it may soon be possible to obtain drinking water from sea water without using a power supply – Gdansk, Poland

Called NanoseenX, the team’s design consists of a cascade of membranes that filter out different impurities, including salt. According to the company, within two minutes you can get 200 ml of water, from which 97 percent of salt is removed.

The NanoseenX solution also has a mineralisation and salinity control, making it possible to remove over 99.9 percent of salt. The device works without a power supply – water flows through the filters due to gravity. The filter can be placed anywhere, for example on a beach or ship.
