Desalination device

A desalination device, comprising:

• a heating unit, configured to receive a dry air stream and heat the dry air stream with one or more renewable energy sources to form a heated dry air stream, wherein the heating unit comprises (i) a water turbine, configured to be rotated by waves, tides and/or water currents;
• (ii) a chamber with an inlet and outlet, the inlet is configured to allow an air stream enter the chamber and the outlet is configured to allow an air stream exit the chamber;
• and (iii) at least two rotors or impellers inside the chamber, the said rotors or impellers are mechanically coupled to the water turbine, the at least two rotors or impellers are configured to rotate with rotation of the water turbine in a synchronized fashion to blow air against each other and air inside the chamber;
• a humidifier, configured to receive the heated dry air stream, evaporate at least portion of water present in the humidifier and humidify the heated dry air stream to form a wet air stream;
• a cooling unit, configured to receive the wet stream and cool the wet air stream resulting in condensation of at least a portion of moisture present in wet air stream to produce fresh water and dehumidified air stream;
• and
• a fresh water collection tank, configured to collect at least a portion of the fresh water.
