Graphene water filter

More developments... would be awesome to be able to go sailing with a graphene water filter and get unlimited drinking water (from sea water). :slight_smile:

... although, in the desert, the more important question is whether this can filter pee and turn it into drinking water. :=0

... so take ocean water to make fresh water and get sodium to make batteries! Win-win. :slight_smile:
