     BACKGROUND OF THE INVENTION 
     This invention relates generally to the collecting/concentrating solar energy to produce heat. In the past, solar collectors generally have been set up in clear, dry desert air. In the late 1800&#39;s a group of solar energy enthusiasts, with their solar equipment traveled to North Africa and the Sahara Desert. With their troughs installed, they discovered that their equipment was only efficient for part of the day. The huge fields of troughs employed by utility companies today move with the sun only from east to west. 
     By not changing direction with the season, today&#39;s troughs are not highly efficient. This invention solves the partial problem of season change. Therefore, the present invention is more efficient. 
     DESCRIPTION OF THE KNOWN ART 
     Patents and patent applications disclosing information relevant to solar energy are disclosed below. These patents and patent applications are hereby expressly incorporated by reference in their entirety. 
     U.S. Pat. No. 3,999,389 to Bryce issued on Dec. 28, 1976 (“the &#39;389 patent”) teaches a solar energy collector converter apparatus employing a closed energy conversion cycle utilizing alcohol as the conversion medium and incorporating a solar energy collector which is equipped to follow the sun. 
     U.S. Pat. No. 4,498,456 issued to Hashizume on Feb. 12, 1985 (“the &#39;456 patent”) teaches a self-tracking mechanism for a solar collector that comprises a plurality of sensor concentrators arranged side by side and a plurality of shape memory alloy coils each located at a position coincident with the focal line of the corresponding one of sensor concentrators. The &#39;456 patent teaches that the shape memory alloy coil is treated so as to shrink into a memorized shape when heated. Each of a plurality of tension wires taught by the &#39;456 patent have one end connected to one end of the shape memory alloy coil and the other end wound up on a wire drum which is mounted on a drive shaft. A transfer mechanism taught by the &#39;456 patent is operatively connected to the drive shaft for transferring the rotation of the drive shaft to a rotatable main collector. 
     U.S. Pat. No. 6,363,928 issued to Anderson on Apr. 2, 2002 (“the &#39;928 patent”) teaches a solar tracking mechanism that is utilized in connection with a solar energy collection system. The collection system taught by the &#39;928 patent includes a light reflective shell shaped to focus solar radiation on a radiation absorbing segment of a tube which carries a heat transfer fluid. The shell taught by the &#39;928 patent is pivotally mounted on a support frame. The &#39;928 patent teaches an actuator mounted between the support frame and the shell rotatably the shell. A solar sensor taught by the &#39;928 patent is mounted deep within a sighting tube which is fixed to the shell such that a line of sight through the sighting tube is at least parallel to the optical axis of the shell. The solar sensor taught by the &#39;928 patent generates a sensor signal which is used as a control input to an actuator control system. End limit switches taught by the &#39;928 patent generate a limit stop signals when the shell reaches maximum angular positions. The actuator control system taught by the &#39;928 patent generates fluid flows to the actuator based the solar sensor signal and the limit stop signals. The &#39;928 patent teaches that the method of tracking the sun includes providing a solar cell array, activating the solar collection system when solar radiation illuminating the array exceeds a predetermined threshold, providing a solar sensor shielded from the solar radiation except for direct, aligned radiation, pivotally rotating the shell westward based upon the solar sensor signal, stopping the shell at a maximum angular positions, and rotating the shell westward if the shell does not reach the maximum westward angular orientation during a predetermined daylight time period. The solar energy collection system taught by the &#39;928 patent may be further configured to include a bisected shell, which are hinged together. The &#39;928 patent teaches that the shell halves can be collapsed onto each other thereby protecting the light reflective surface and the radiation absorbing segment of the tube carrying heat transfer fluid. 
     Therefore, the present invention is needed to improve the transfer of solar energy to a fluid flowing through a heating conduit heated by a reflective surface. The present invention is also needed to increase the efficiency of heating a conduit. The present invention is also needed to decrease movement of the conduit as the reflective surface pivots on two axes.

     DETAILED DESCRIPTION 
     The present invention, with its twelve-volt motors, is capable of following the sun from sunrise to sunset. The moveable mirror, capable of 360° in its torrent, keeps the sun focused on the receiving tube. The mainframe tilts from North to South, keeping the sun in full focus during the changing seasons. 
     The tubing and receiver may contain glycol, mineral oil, petroleum oil, or any medium not affected by the weather. The medium oil contained in the tubing system may be (350°) transferred by pump to any other system for practical use, such as water heater, producer of steam, etc. All the sunshine sensing and relay energizing is accomplished by use of red rock component (led 3×). 
     Referring to  FIG. 1 , the present invention allows tracking of the sun on two different axes. In one embodiment, the present invention rotates on a first axis and a second axis, substantially perpendicular to the first axis, to allow for tracking of the sun from east to west and north to south. Thus, the present invention tracks the sun during the day and adjusts according to the time of year. Reflective surface  10  focuses the sunlight onto heating conduit  5 . Reflective surface  10  mounts onto the present invention such that reflective surface  10  may be positioned on two different axes for tracking the sun. In one embodiment, reflective surface  10  mounts on collector frame  3  for movement on a single axis for tracking the sun on a daily basis from east to west. Collector frame  3  pivotally mounts to adjustment body  2  for pivoting of collector frame  3  and reflective surface  10  in relation to adjustment body  2 . Adjustment body  2 , likewise, pivotally attaches to base  1  for pivoting adjustment body  2  on the second axis. The pivoting of adjustment body  2  allows the present invention to track the sun on a second axis. 
     Referring to  FIG. 2 , base  1  rests upon a surface such as the ground or other surface. Motor  23  attaches to base  1  at mounting body  114 . In one embodiment, base  1  provides a surface contact  116  forming a parallelogram for contact with the surface. Four legs  118  extend upward from the surface contact  116  to meet at the top to form two different triangles. The two legs  118 ,  122  and two legs  120 ,  124  extend from surface contact  116 . Leg  118  and leg  122  extend parallel from each other and leg  120  and leg  124  extend parallel from each other. Legs  118  and  120  meet at an upper portion of base  1 . Likewise, legs  122  and  124  meet at an upper portion of base  1 . The upper portion of base  1  provides a mounting aperture  112  for attachment of adjustment body  2 . Fasteners pivotally attach adjustment body  2  to base  1 . 
     Referring to  FIGS. 3 and 6 , adjustment body  2  pivotally attaches to base  1 . Pivot body  25 , a pulley in one embodiment, attaches to adjustment body  2 . Motor  23  attached to base  1  pivots adjustment body  2 . Belt  29  attaches to a driving body  24  secured to motor  23 , such as a shaft, and pivot body  125 . Motor  23  rotates driving body  24  thus translating into movement of belt  29 . As the belt  29  moves, the belt  29  rotates pivot body  25 . The rotation of pivot body  25  pivots adjustment body  2  for tracking the sun on an axis, such as north and south. 
     Attachment legs  126 ,  128  of adjustment body  2  pivotally attach to base  1 . Attachment legs  126 ,  128  extend downwards in a V-shape to be secured to base  1 . Pivot body  25  attaches to attachment leg  126 . Attachment arms  130 ,  132  extend upwards from adjustment body  2 . Attachment arms  130 ,  132  form a V-shape to support collector frame  3 . Attachment arms  130 ,  132  provide pivoting apertures  131 ,  133  for the supply conduit  4  to attach with the heating conduit  5 . Reflective surface  10  also attaches to adjustment body  2  at pivoting apertures  131 ,  133 . Therefore, reflective surface  10  pivots around heating conduit  10  so that the reflective surface  10  will concentrate the sun&#39;s energy towards the heating conduit  10 . 
     Referring to FIGS.  3  and  5 - 6 , reflective surface  10  mounts onto collector frame  3 . The collector frame  3  supports the reflective surface  10  during the tracking of the sun on one axis. In one embodiment, collector frame  3  tracks the sun from east to west. Heating conduit  5  passes through conduit apertures  149 ,  153  of collector frame  3 . Heating conduit  5  does not adjust during the movement of collector frame  3  during the tracking of the sun by collector frame  3 . Pulley  11  adjusts the collector frame  3  on one axis for tracking the sun. The movement of collector frame  3  will be described in greater detail with reference to  FIG. 4 . 
     Collector frame  3  pivotally attaches to adjustment body  2  for movement on a single axis. Collector frame  3  pivots in relation to adjustment body  2  to allow collector frame  3  to track the sun on a single axis. Adjustment body  2  pivotally attaches to base  1  for pivoting of adjustment body  2  on a single axis. Attachment arms  130 ,  132  of adjustment body  2  extend upwards for attachment of collector frame  3 . Collector frame  3  pivotally attaches to attachment arms  130 ,  132 . The pivoting of adjustment body  2  on one axis and collector frame  3  on another axis enables reflective surface  10  to track the movement of the sun on two different axes. Conduit apertures  131 ,  133  of adjustment body  2  enable the connection of heating conduit  5  to supply conduit  4 . The extension of attachment arms  130 ,  132  above the main portion of adjustment body  2  elevates the collector frame  3  such that collector frame  3  may pivot freely without contacting the main portion of adjustment body  2 . The extension of attachment arms  130 ,  132  also elevate heating conduit  5  substantially proximate to the pivot point of the reflective surface  10  for heating the fluid within heating conduit  5 . 
     Motor  123  attaches to adjustment body  2  for movement of collector frame  3  and reflective surface  10 . Motor  123  attaches to driving body  24 . Driving body  24  accepts belt  28  for adjustment of belt  28 . Belt  28  also attaches to pivoting body  11 . As driving body  24  secured to motor  123  adjusts belt  28 , belt  28  also adjusts pivoting body  11 . Collector frame  3  and reflective surface  10  pivot during movement of pivoting body  11  for tracking of the sun&#39;s movement by reflective surface  10 . 
     Referring to  FIG. 4 , collecting frame  3  provides supports  134 ,  136 ,  138 ,  140  adapted to support the reflective surface  10 . Side supports  144 ,  146  also support reflective surface  10  as reflective surface  10  tracks the movement of the sun. Vertical supports  148 ,  150 ,  152 ,  154  extend upwards from collecting frame  3 . Vertical supports  148 ,  150 ,  152 ,  154  provide attachment apertures  149 ,  153  for attachment of the collecting frame  3  to pivot body  11  and adjustment body  2 . As stated above, pivoting body  11  attaches to collector frame  3 . Belt  28  adjusts pivoting body  11  to pivot collector frame  3  and reflective surface  10 . Attachment apertures  149 ,  153  provide the proximate location for attachment of collector frame  3  and reflective surface  10  such that reflective surface  10  pivots around attachment apertures  149 ,  153 . The attachment apertures  149 ,  153  allow fasteners to pass through attachment apertures  149 ,  153  for attachment of collector frame  3  to adjustable body  2  through the pivoting apertures  131 ,  133 . In one embodiment, heating conduit  5  and supply conduit  4  pass through attachment apertures  149 ,  153  and pivoting apertures  131 ,  133  such that reflective surface  10  pivots around heating conduit  5 . In such an embodiment, reflective surface  10  revolves around heating conduit  5 . 
     Referring to  FIGS. 5 and 6 , the present invention provides a heating conduit  5  for heating a fluid. A reflective surface  10  adjusts on a first axis and a second axis to follow the movement of the sun. The reflective surface  10  reflects solar rays towards the heating conduit  5  to heat the fluid found in the heating conduit  5 . Reflective surface  10  pivots around heating conduit  5 . In one embodiment, heating conduit  5  provides the central point around which heating conduit  5  pivots. In one embodiment of the present invention, the reflective surface  10  is a concave mirror. The heating conduit  5  provides a passageway for movement of the fluid. The heating conduit  5  has two ends, an entrance end  106  and an exit end  108 . The entrance end  106  of the heating conduit  5  allows the fluid to enter the heating conduit  5  to be heated. The exit end  108  of the heating conduit  5  allows the heated fluid to exit the heating conduit  5 . 
     The present invention also provides a supply conduit  4  attached to the heating conduit  5 . The supply conduit  4  provides a passageway for transferring the fluid that needs to be heated toward the heating conduit  5  to be heated. As the fluid passes from the supply conduit  4  through the entrance end  106  of heating conduit  5 , the fluid is heated from direct solar rays and reflected solar rays from the reflective surface  10 . As the fluid heats, the fluid flows through heating conduit  5  towards exit end  108 . The supply conduit  4  also provides a passageway for transferring the fluid away from the heating conduit  5  for use. After flowing through exit end  108 , the fluid enters supply conduit  4  to be transferred for use. As the fluid flows away from heating conduit  5 , the fluid loses some of its heat. The present invention provides a cycle for continued use of the fluid. As the fluid loses heat, the fluid returns through supply conduit  4  to be reheated in the heating conduit  5  as shown in  FIG. 6 . 
     The movement of the present invention to follow the sun to improve the efficiency of the present invention will now be described in greater detail. As discussed above, the reflective surface  10  reflects solar rays towards the heating conduit  5 . The reflective surface  10  adjusts on a first axis and a second axis to track the movement of the sun during the day and throughout the year. The reflective surface  10  pivotally attaches to adjustment body  2 . The pivotal attachment of the reflective surface  10  allows the reflective surface  10  to adjust on a first axis. In one embodiment of the present invention, pivoting of the reflective surface  10  on the first axis allows the present invention to track the daily movement of the sun. The heating conduit  5  does not move as the reflective surface  10  adjusts on the first axis. Attachment apertures  149 ,  153  provide the proximate location for attachment of collector frame  3  and reflective surface  10 . Reflective surface  10  pivots around attachment apertures  149 ,  153 . Because heating conduit  5  and supply conduit  4  pass through attachment apertures  149 ,  153 , reflective surface  10  also pivots around heating conduit  5  and supply conduit  4 . In one embodiment of the present invention, heating conduit  5  and supply conduit  4  remain fixed as the reflective surface  10  pivots on the first axis with the collector frame  3 . 
     The present invention also provides movement of the reflective surface  10  on a second axis during the movement of the adjustment body  2 . The adjustment body  2  pivots on a single axis, distinct from the axis that the collector frame  3  pivots. The pivoting of adjustment body  2  allows adjustment of the reflective surface  10  on the second axis. The supply conduit  4  pivots with the adjustment body  2 . The attachment of the supply conduit  4  with the adjustment body  2  allows supply conduit  4  to pivot with adjustment body  2 . Therefore, the supply conduit  4  remains fixed in relation to the adjustment body  2 . The supply conduit  4  is fixedly attached to the heating conduit  5  such that heating conduit  5  remains in a fixed position during pivoting of the reflective surface  10  on the collecting frame  3 . 
     The present invention also provides exchange conduit  110  for transferring the fluid from the supply conduit  4  to be used. As the fluid is transferred away from heating conduit  5 , the fluid loses heat. After the fluid transfers heat gained from heating conduit  5  during use of the fluid, the fluid flows from exchange conduit  110  to supply conduit  4  and heating conduit  5  for reheating. As stated above, heating conduit  5  and supply conduit  4  adjust with the pivoting of adjustment body  2 . To allow such movement, supply conduit  4  rotatably attaches to exchange conduit  110 . As seen in FIGS.  3  and  5 - 6 , supply conduit  4  enters conduit attachment  127  of adjustment body  2 . Conduit entrance  127  and conduit exit  129  allow supply conduit  4  to extend approximately perpendicular to the axes on which adjustment body  2  pivots. Such attachment allows supply conduit  4  to pivot with adjustment body  2 . The pivoting of supply conduit  4  with attachment body  2  limits the number of pivotal attachments to supply conduit  4  to two different connections, each exterior of conduit entrance  127  and conduit exit  129 . The two pivotal attachments occur at the joining of supply conduit  4  to exchange conduit  110 . 
     In one embodiment of the present invention, reflective surface  10  adjusts at least 180 degrees on the first axis to allow daily tracking of the sun as the Earth rotates. Another embodiment allows 360 degrees of movement of the reflective surface  10 . The 360 degree movement of reflective surface  10  allows reflective surface  10  to pivot around heating conduit  5  to serve as a shelter for heating conduit  5 . The reflective surface  5  may be adjusted to a protect position in which the reflective surface blocks rain, dirt, snow, and other environment factors that may affect the heating conduit  5 . One embodiment of the present invention also allows reflective surface  10  to adjust at least 180 degrees on the second axis to track the sun as the Earth revolves around the sun. The adjustment of the reflective surface  10  allows the present invention to heat the liquid to a minimum of at least 350 degrees Fahrenheit. 
       FIGS. 10 and 11  show the adjustment body  2 . In one embodiment, adjustment body  2  provides attachment arms  130 ,  132  that extend 70 to 90 inches above the central portion of adjustment body  2 , 81.5 inches in one embodiment. Attachment arms  130 ,  132  extend approximately 45 to 65 inches apart, 52 inches in one embodiment.
