Desolenator - the first easy to use, low cost, solar powered (so no electricity required) water desalination system that can make any type of water - including sea water - drinkable.
Existing desalination systems are also highly energy intensive which makes them not just expensive to maintain but also a major producer of carbon emissions - which, quite frankly is only making the water problem worse.
They are dreaming of the day when every community that has struggled to access clean water has a Desolenator whizzing away in the background making clean and safe water for them to drink.
