annular rings 315 315 to form a ripple like design thereon water enters the vaporization chamber 10 by means of a feed hose 60 and an automatic valve 50 said automatic valve is provided with a float 55 to open the valve when the water level falls below a specified level and to close the valve when the water level attains a second specified level because the convex lenses 314 are of different sizes and thicknesses the heat focus points relative thereto will be at different levels in the vaporization chamber 10 to insure greater efficiency the rings 315 will cast a plurality of heat focus points on the surface of the water and in the air above thus raising the temperature within the vaporization chamber 10 when the vaporization chamber 10 is filled with water the water is heated by virtue of the capacity of the lens cover 31 to cause rays of sunlight to converge at various focus points in on and above the water as the water is vaporized the vapor rises through the partition 14 by means of the holes 143 provided thereon and into the condensation chamber 20 cool air enters cooling air chamber 30 by means of the plurality of vents 312 312 as cool air passes between condensation plate 21 and lens cover 31 the temperature of condensation plate 21 is maintained at a much lower level than that of the water vapor so that when the water vapor comes into contact with the condensation plate 21 it will be condensed to water droplets as the water droplets accumulate and increase in size they will drop from the condensation plate 21 onto the corrugated partition 14 below and into the depressed portions 142 thereof wherefrom the accumulated water will flow downwards and.
