Solar heat control apparatus for a body of water

A solar heat control apparatus for a body of water comprising

• a structural frame adapted to be supported at an upper surface region of a water body, and
• solar radiation conversion and heat transfer control means carried by said frame, said control means including at least one heat conductive plate having first and second surfaces on opposite sides thereof and mounted on said frame for selective movement of said plate relative to the upper surface of a water body, said plate having a first marginal edge portion immersible in the water body and a second marginal edge portion projecting above the water body to thereby affect control of solar radiation effectively incident to the first surface of said plate and converted to heat energy and to control transfer of heat energy relative to the water body in accordance with the relative position of said plate to the upper surface of the water body, wherein said plate is selectively movable to increase or decrease the extent to which the first marginal edge portion thereof is immersed in the water body.
