Abstract

A machine for tracking the sun's movement and concentrating sunlight consists of a main Frame which pivots in the north and south direction on a base having conduit for a heat medium (a liquid usually of the Glycol family the Main Rrame supports the Mirror Frame that pivots 360 degrees East to West allowing the mirror to focus the sunlight onto the conduit heating the liquid medium producing a very high and concentrated amount of heat during the entire day-light period and can be used for a small business or residential heating. An optional prism can be attached to the mirror frame to focus sun rays onto the conduit for added heat.

Description

    OPERATION—CLAIMS
  • The Sunshine Tracker is a miniaturization of the giants used by utility companies in large fields and is meant to be used by individuals in homes or small business!
  • The Sunshine Tracker, with its twelve-volt motors, is capable to follow 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×).
  • Trough Sunshine Concentrator Partial History
  • In the late 1800's a group of solar energy enthusiasts, with their solar equipment traveled to North Africa and the Sahara Desert. There they set up their equipment in the clear, dry desert air! With their troughs installed they discovered since they were not movable in sync with the sun, the troughs were 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 season change, today's troughs are not highly efficient.
  • The Sunshine Tracker solves the partial problem of season change, therefore is more efficient.
