A saltwater evaporation mechanism for the desalination of saltwater. The saltwater evaporation mechanism has an elevated saltwater reservoir with a bottom, sidewalls and an open upper end, a receiving reservoir with a bottom, sidewalls, and an open upper end, and a tunnel extending therebetween. The tunnel has a top panel, a bottom panel, and two side panels and is angled at a downward slope. The top panel extends from the tunnel to entirely cover the open upper end of the saltwater reservoir. Support legs equipped with wheels are positioned below the tunnel, allowing the tunnel to be easily moved and rotated when desired. A heat source is positioned underneath the saltwater reservoir and configured to heat the contents therein, creating water vapor. The water vapor condenses into desalinated water in the tunnel and is deposited in the receiving reservoir. In some embodiments, the heat source is powered by solar energy.
