The seawater evaporator is a closed cavity. The seawater evaporator is connected with the power generation device body through the gas guide pipe. A porous material which can float on seawater is arranged in the seawater evaporator. The horizontal plane of the seawater injected into the seawater evaporator is lower than a communication interface of the gas guide pipe and the seawater evaporator. The power generation device body is a vapor condensation power generation device body. Through the porous characteristic of sponge, the surface of the power generation device is modified to efficiently absorb solar energy, water molecules on a phase interface of seawater and air can efficiently collect heat, and then vapor is generated for seawater desalination.
