      The Future is Now "Indoor Passive Solar Window Box Heaters"

      These lightweight - portable solar passive heating boxes and can create and
      push out temperatures of 96 °F into any room. The unit is designed to pull
      cool air fom the bottom of the unit.
      The cool is pulled upward and over the heated aluminum cans - metal
      interior, and hot air is returned into the room by small solar fans through
      the top vents.

      The days of large - costly - huge outdoor collectors are gone.

      We need portable lightweight - efficient units that mount on the inside.
      The unit is 32" Tall - 20" Wide - 4 " Depth.
      It costs less than $60.00 to manufacturer each unit, and uses 4 small solar
      fans.

      These units sit flush on the inside window sill or bay window.
      The manufacturing process for these units is streamlined and repeatable.

      Any comments or suggestions?
      Please compare Outdoor solar collectors vs Indoor Passive Solar Window
      Boxes.
      Outdoor collectors or heater boxes are 6 feet in length. They consume an
      entire window.
      Not to mention the eyesore appearance they give any yard or home.

      We need alternative solar heating, this is one way to reduce your monthly
      heating bills!
      I live in the Northeast - these are the perfect winter heating units!!!!!

      I am using aluminum 12 oz cans painted flat black to generate the heat.
      I have tried many different metals, and various types of tubing etc.
      The aluminum cans heat up the fastest in direct and partial sun.
      The cans are chimney stacked for quick heat rise.

      I am seeking feedback on the materials and the various stacking designs.

      "Active solar heating uses devices such as pumps, fans and controls to move
      warmth around. Passive solar heating, on the other hand, collects and
      distributes heat without any mechanical or electrical devices."
      "The internal fans are Solar, its still considered a passive solar window
      box heating unit"

      * Passive solar heating systems need five components, according to the U.S.
      Department of Energy: a collector, absorber, thermal mass, distribution and
      control
