A solar desalination system includes a solar furnace for receiving seawater into a vessel and concentrating sunlight on the vessel to heat that water using solar energy to create desalinated steam. Water is input into the furnace via a pump that is powered by a reciprocating solar engine. The reciprocating solar engine includes a seesawing platform with a closed system of two or more connected containers thereon. Solar heating causes a fluid to move from one container to another causing the platform to reciprocally rotate through a predetermined arc, creating energy that can be harnessed.
