ABSTRACT:
Water or other heat-conducting liquid is heated in an upwardly open, substantially hemispherical outer bowl, the inside surface of which is treated to absorb heat from the sun's rays. The water or other liquid is introduced at the rim of the outer bowl and runs down the inside surface thereof, thereby being heated by the combined effects of the sun's rays and the heat absorbed by the outer bowl. A transparent, substantially hemispherical inner bowl is positioned within and spaced from the outer bowl to form a passageway for the water or other liquid. A tube or pipe is provided at the bottom of the outer bowl for allowing heated water or other liquid to drain from that bowl, and another tube or pipe is provided at the bottom of the inner bowl for allowing rain or melted snow to drain from that bowl.
