In a nutshell, this is a system to get fresh water from sea water.
The main component is a filter. For the filtration to work the water must be supplied under a high pressure what is achieved by placing the water to the high level.

The key advantage (compared with another similar sea water desalination solutions) of this system is that it is powered by solar energy (no batteries/need for electricity = no pollution (including CO2)).

Also it can be scaled to be used as for a single home as for an entire village.

Basically: solar/wind energy + gravity + sea => fresh water

Important:

The technology has been successfully tested in the field during a pilot in Indonesia and is ready for commercial implementation
