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.

1. A method for desalinating fluid using solar energy from the sun, comprising the steps of: a) heating the fluid in a grid using solar energy, the grid having an upper end with first and second openings into said grid and a lower, closed end wherein the upper end is elevated above the lower end to
1. A method for desalinating fluid using solar energy from the sun, comprising the steps of: a) heating the fluid in a grid using solar energy, the grid having an upper end with first and second openings into said grid and a lower, closed end wherein the upper end is elevated above the lower end to permit vaporized fluid to be released from the grid, said grid comprising primary, parallel arranged and spaced conduits extending from the lower end to the upper end of said grid, and secondary conduits interconnecting said primary conduits;b) using a first magnifying lens for receiving the solar energy and directing the solar energy onto the grid, wherein the fluid in the grid is heated to a state of vaporization to produce vaporized fluid;c) transferring the vaporized fluid through the upper end first opening of the grid directly to a steam turbine;d) said steam turbine driving an electrical generator for generating electricity;e) condensing the vaporized fluid from the steam turbine in a condenser, the condenser having an inlet for the vaporized fluid, a first outlet for waste vaporized fluid, and a second outlet for desalinated fluid condensate;f) supplying fluid from a fluid reservoir to the grid through said upper end second opening, said fluid reservoir receiving waste vaporized fluid from said first outlet of the condenser;g) using an electrical pump for conveying fluid to the grid;h) rotating the first magnifying lens and the grid so that an energy efficient angular relationship is maintained between the first magnifying lens, the grid, and the sun;i) storing in a storage battery electricity from the electrical generator, wherein the storage battery supplies electricity to the electrical pump and for rotating the magnifying lens and the grid;j) controlling the fluid level in the grid to prevent overfilling or emptying of the grid using float balls in one of said primary conduits to maintain fluid levels in said primary conduits; and,k) removing waste periodically from the grid. 2. The method of claim 1, further comprising the step of providing a second magnifying less in series with the first magnifying lens and the sun. 3. The method of claim 1, wherein rotating the first magnifying lens and the grid further comprise the steps of: a) providing a rotatable platform upon which the first magnifying lens and the grid are disposed for rotating the first magnifying lens and the grid;b) using an electrical motor for rotating the platform; and,c) wherein the electrical motor receives electricity from the storage battery. 4. The method of claim 1, wherein the condenser is a reflux condenser. 5. The method of claim 1, wherein controlling the fluid level in the grid further comprises the steps of: a) using an upper sensor for sensing when the float ball is proximate thereto, the upper sensor disposed proximate the upper end of said grid;b) using a lower sensor for sensing when the float ball is proximate thereto, the lower sensor disposed proximate the lower end of said grid;c) said electrical pump being turned on by the lower sensor when the float ball is proximate the lower sensor so that fluid is inlet into the grid; and,d) said electrical pump being turned off by the upper sensor when the float ball is proximate the upper sensor to prevent overfilling of the grid. 6. The method of claim 5, wherein removing waste from the grid further comprises the steps of: a) using a normally closed outlet valve on the lower end of each primary conduit;b) each outlet valve being periodically opened so that waste is removed from the grid to permit the grid to be cleaned; and,c) using a main control switch for controlling the operation of the outlet valves. 7. The method of claim 1, wherein the fluid comprises saltwater. 8. A method for desalinating water comprising the steps of: a) pumping salt water into a grid comprising a plurality of spaced, parallel, primary conduits, said grid having a manifold at an upper end of said grid for receiving and delivering said salt water into each primary conduit, said primary conduits each having a closed lower end with a normally closed outlet valve, and secondary conduits for providing communication between said primary conduits;b) directing solar energy onto said primary conduits for vaporizing said water therein, resultant water vapor rising into said manifold;c) transferring vaporized water from said manifold to an inlet of a steam turbine for operation of said steam turbine;d) said steam turbine driving a generator for producing electricity;e) condensing vaporized water exhaust from the steam turbine in a condenser;f) withdrawing waste vaporized water through a first outlet of said condenser;g) withdrawing desalinated water through a second outlet of said condenser;h) storing electricity produced by said generator in a battery;i) using electricity stored in said battery to operate equipment required by said method;j) controlling water levels in said primary conduits using a float ball in one of said primary conduits for preventing overfilling and for adding salt water when levels in said primary conduits reach a predetermined lower level; and,j) cleaning said primary conduits periodically by opening said primary conduit outlet valves.
