Abstract: A solar water distiller is set forth utilizing a spherical boiler formed with an underlying concave reflective lens arranged for tracking of the position of the sun to effect boiling of water provided within the solar boiler. Water vapor is forcibly removed from the uppermost portion of the spherical boiler by a solar powered pump directing the cooling water into a condensate tank that is provided with a pressure relief valve. The spherical boiler is provided with a float level and a pressure gauge to control the actuation of a valve limiting water provided to the spherical boiler to maintain the spherical boiler with a half volume of fluid for maintaining efficiency of the boiler.
