Abstract
A geometric dome comprises a number of interconnected members which are
arranged at specific angles. The geometric dome is excellent in strength due to
the angular configuration of each member. One member of the dome is in the form
of a convex lens and the rest of the dome is made up of two-way mirrors with the
planes of the mirrors facing internally of the geometric dome.
Sunlight is
concentrated and directed to pass through the convex lens of the geometric
dome.
As concentrated sunlight passes through the convex lens, the light will be
spread out internally of the geometric dome. Solar cells are arranged to face
each other and receive light internally of the geometric dome, by means of the
convex lens.

Claims
What is claimed is:
1. A dome-shaped housing structure including a plurality of solar electric cells
in the interior space thereof, comprising: a dome constructed from a number of
interconnected members, said members being inclined at different angles to form
a geometric dome; and a plurality of solar electric cells forming at least part
of said interconnected members, said solar electric cells being disposed
interiorly of said geometric dome; and at least one said interconnected member
being a convex lens to allow solar energy to pass into the interior of said
geometric dome.
2. The means of claim 1 wherein at least part of said interconnected members are
two-way minors with planar surfaces disposed in different directions whereby
sunlight can enter said geometric dome at all solar angles.
Description
INVENTION
BACKGROUND
Collecting sunlight and transforming it to electricity by means of
solar cells is a well understood technology today. For reasons of brevity, a
description of solar electricity will not be given. The advantage of the present
invention will come from the specific arrangement of said solar cells and in no
way from the modification of solar cells. Presently there are a number of
companies throughout the United States of America that sell solar cells for
generation of electricity.
Due to photovoltaic solar cells typically having only one electrically producing
face, the collectors must be positioned so that the surroundings such as trees
or buildings, will not block the path between the sun and solar cells. This
requirement is usually satisfied by positioning the solar cells in an open field
or on top of a building. Another problem, which occurs with solar cells, is in
the nature of reflection. Typically, a group of solar cells are positioned
side-by-side; therefore sunlight has only one opportunity to be absorbed by the
cells before reflections occurs.
Another problem occurs with the current solar cells because of the natural
movement of the sun during different times of the day and the season of the
year. Tracking the sun's actual position, regardless of time or season is
possible, but only through an elaborate and expensive control system. Elaborate
tracking systems can incur mechanical problems.
An example of a prior art silicon solar cell is illustrated in FIG. 1.
Typically, plurality of solar electric cells are positioned side-by-side,
therefore having only one opportunity to absorb light.
INVENTION
SUMMARY
The present invention contrasts sharply with the current side-by-side
arrangement of solar cells. The present invention relates to an improved
mounting and support structure for housing solar cells. The present invention
also relates to an improved means for concentration of sunlight for solar cells.
The advantage of the present invention will come from the specific arrangement
of solar cells and an improved concentration of sunlight. The advantages of the
present invention do not arise from the modification of currently available
solar cells.
The present invention may be accomplished by combining a number of
interconnected angular members into a structure which serves as the housing and
support structure for the solar cells. Solar cells are attached to specific
members of the housing structure.
In contrast to the side-by-side arrangement, the solar cells in the present
invention are in facing relation to each other.
A solar energy collection apparatus embodying the present invention comprises a
housing structure made up of as number of interconnected angular members. All
interconnected angular members are made up of two-way mirrors, with the plane of
each mirror facing internally of the housing structure. The interconnected
angular members define a light receiving surface which serves as a peripheral
edge of which solar rays are allowed to penetrate through any of the
interconnected angular members.
In accordance with the present invention, the collection apparatus includes a
cooperating combination of a convex lens providing a generally conical
projection of concentrated sunlight to be directed internally of the housing
structure. The convex lens is specifically an interconnected angular member of
the housing structure and serves as another entrance for incident light.
Another device of the present invention includes an arrangement of cooperating
pairs of solar cells in facing relation attached to opposite sides of the
housing structure and having a general dome shape.
In view of the above, an object of the present invention is to provide a solar
energy collection apparatus which includes an improved polyhedral housing
structure which will assist in support and arrangement of solar cells.
Another object of the present invention to increase the efficiency of the solar
cells. Improvement in efficiency will come from an improvement of capacity to
absorb sunlight by means of an arrangement of solar cells.
Other objects, together with the foregoing, are attained in the embodiments
described in the following description and illustrated in the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
All interconnected angular members are made of two-way mirrors. The mirror plane
will face internally of the geometric dome thus allowing light to enter through
all sides of the geometric dome. All interconnected members must be specifically
angled so the structure will form a dome with mechanical strength.
There will be a total of sixty-two interconnected angled members, thirty of
which are in specific form of a square 14 shown in FIG. 4, with one in the
specific form of a convex lens 16, which is represented in FIG. 8.
There will be twenty hexagons 13, as shown in FIG. 4. A solar cell as shown in
FIG. 1 will be attached to hexagons 12 in FIG. 2. There will be twelve decagons
15 as shown in FIG. 4. The Dihedral Angles are as follows: 148.degree. 17'
(decagon-square), 142.degree. 37' (decagon-hexagon), 159.degree. 6'
(hexagon-square).
A specific interconnected part of the structure will be in the form of a convex
lens 16. The lens is shown in FIG. 8. One must be able to substitute lenses for
squares on the dome surface; the cooperation of the convex lens incorporated
into the structure is paramount for the specific purpose of concentrating
sunlight inside the geometric dome. Like the solar cell shown in FIG. 1, a
convex lens, shown in FIG. 8, is also available commercially. The convex lens
must be the same size as the other interconnected squares which make up a
portion of the geometric dome. This concentrator of sunlight is advantageously
used in the present invention. The convex lens concentrates the sunlight in a
conical shape instead of a pin-point shape. The convex lens does not need to
have precise optical properties since the conical shape of sunlight is the
advantage. Instead of a small spot, the convex lens 8 produces a wider light
beam, which is represented in FIG. 8, which is directed inside of the dome.
