Abstract: Method and apparatus for desalinization wherein a heating grid containing a fluid is used to heat the fluid to a vaporized state using energy provided by compound magnifying lens focusing solar energy directly onto the grid wherein the vapor from the grid system is transmitted to a steam turbine wherein electricity is generated to charge a battery while the vapor from the steam turbine is conducted to a condenser wherein the vapor is cooled and fresh water is provided from the condensate. The remaining fluid from the condenser is pumped back into a reservoir for storage while waiting to be conducted into the heating grid. The magnifying lens and grid is rotated for alignment with the sun.
