Abstract:
1. An apparatus for producing a mass of water vapor, the apparatus comprising: a water film maker floating on a surface of a water source, said water film maker absorbing water of the water source by virtue of a capillary mechanism or a moisture-holding ability to make a thin water film on a surface of the water film maker, the thin water film being exposed to sunlight, and the water film maker having a black surface to absorb sunlight energy and vaporize water in the thin water film; and a device which prevents the water film maker from drifting on the surface of the water source, wherein said water film maker comprises a first hollow body capable of being filled with air, and a sheet having said capillary mechanism or having said moisture-holding ability, said sheet covering said first hollow body, and wherein water in the thin water film is vaporized by sunlight energy to thereby produce a mass of water vapor in the sky.
