Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
145 words
An apparatus for collecting and concentrating solar light energy comprising; a transparent container; lens means movably supported in and by the container, for collecting and concentrating solar light energy; optical fiber means located at the focus of the lens means and extending to the outside of the container to transmit the collected sunbeams to the outside of the container; first drive means for rotating the lens means about a vertical axis; second drive means for rotating the lens means about a horizontal axis, independently of the drive of the first drive means; solar cell means connected to the first and second drive means to drive the same; and, means movable with and supported by the lens means, for detecting the position of the sun, said detecting means being connected to the drive means to drive the latter in accordance with the position of the sun.
Claim 2
Independent Claim
145 words
An apparatus for collecting and concentrating solar light energy comprising; a transparent container; lens means movably supported in and by the container, for collecting and concentrating solar light energy; optical fiber means located at the focus of the lens means and extending to the outside of the container to transmit the collected sunbeams to the outside of the container; first drive means for rotating the lens means about a vertical axis; second drive means for rotating the lens means about a horizontal axis, independently of the drive of the first drive means; solar cell means connected to the first and second drive means to drive the same; and, means movable with and supported by the lens means, for detecting the position of the sun, said detecting means being connected to the drive means to drive the latter in accordance with the position of the sun.
