Solar collector

Claim 2

Claim 3

A solar energy collector as set forth in claim 1 wherein said absorbing surface has a peripheral edge defined by the outer edge of a marginal portion of said surface, said marginal portion having an inner boundary defined by said locii of said centroids of said focii.

Claim 4

A solar energy collector as set forth in either claim 1 or claim 2 wherein said lense means comprises a fluid lense.

Claim 5

A solar energy collector as set forth in claim 3 wherein said lense means and said collector body cooperate to define a housing having a chamber therein and said absorbing means is located within said chamber.

Claim 6

A solar energy collector as set forth in claim 4 wherein said housing has a generally spherical configuration.

Claim 7

A solar energy collector as set forth in claim 4 wherein said absorbing means comprises a plate mounted in fixed position within said chamber and defining said absorbing surface.

Claim 8

A solar energy collector as set forth in claim 6 wherein said energy absorbing surface defines a portion of the inner surface of said collector body and the remaining portion of said inner surface comprises an energy reflecting surface.

Claim 9

A solar energy collector as set forth in claim 3 wherein said lense comprises a shell containing a quantity of fluid and the index of refraction of the material from which said shell is made is substantially equal to the index of refraction of said fluid.

Claim 10

A solar energy collector as set forth in claim 3 wherein said lense comprises a plastic shell containing a quantity of ethylene glycol.

Claim 11

A solar collector as set forth in any one of claims 1, 2 or 3 wherein said lense means comprises a concavo-convex lense.

Claim 12

A solar energy collector as set forth in claim 3 including energy transfer means disposed in energy exchange relation with said energy absorbing surface.

Claim 13

A solar energy collector as set forth in claim 11 wherein said energy absorbing means comprises a plate defining said energy absorbing surface and said energy transfer means comprises a network of fluid conduit disposed in contact with said plate.

Claim 14

A solar collector comprising a collector body, means securing said collector body in fixed and static position on the surface of the earth at a fixed latitudinal and longitudinal position, said collector body including a generally hemispherical upwardly opening shell having a generally hemispherical inner surface, energy absorbing means disposed within said shell for receiving and absorbing solar energy and having an energy absorbing surface partially defining said hemispherical inner surface, concavo-convex lense means mounted on said collector body for continuously focusing rays of the sun on said absorbing surface throughout the year including solar days of the summer and winter solstice at said fixed latitudinal and longitudinal position, said lense means forming a closure for said upwardly opening shell, said shell and said lense means cooperating to define a chamber containing said energy absorbing means, said absorbing surface having a peripheral shape defined by locii of centroids of the focii of said rays of the sun focused on said absorbing surface by said lense means during said solar days of the summer and winter solistice as determined by the fixed and static position of said collector body at said fixed latitudinal and longitudinal position.

Claim 15

A solar collector comprising a collector body, means securing said collector body in fixed and static position on the surface of the earth at a fixed latitudinal and longitudinal position, said collector body including a generally hemispherical upwardly opening shell having a generally hemispherical inner surface, energy absorbing means disposed within said shell for receiving and absorbing solar energy and having an energy absorbing surface partially defining said hemispherical inner surface, concavo-convex lense means mounted on said collector body for continuously focusing rays of the sun on said absorbing surface throughout the year including solar days of the summer and winter solstice at said fixed latitudinal and longitudinal position, said lense means forming a closure for said upwardly opening shell, said shell and said lense means cooperating to define a chamber containing said energy absorbing means, said absorbing surface having a peripheral shape defined by locii of centroids of the focii of said rays of the sun focused on said absorbing surface by said lense means during said solar days of the summer and winter solistice as determined by the fixed and static position of said collector body at said fixed latitudinal and longitudinal position.

Claim 16

A solar collector as set forth in claim 13 wherein said concavo-convex lense means comprises a fluid lense including a lense shell and a quantity of fluid contained within said shell.

Claim 17

A solar energy collector as set forth in claim 14 wherein said fluid has an index of refraction substantially equal to the index of refraction of said lense shell.

Claim 18

A solar energy collector as set forth in any one of claims 13 through 15 wherein said absorbing means comprises a parti-spherical plate mounted within said chamber.
