Abstract
A facility for generating technically useable energy by converting solar energy in which a single large concave mirror is disposed in a depression in the ground and has supported thereabove a supporting structure, on a support arm of which an elongated energy collector is provided extending from the theoretical focal point for rays on the axis to the periphery of the spherical mirror, said supporting structure supporting the energy collector for rotation about the center of the mirror to follow the changing position of the sun. Also disclosed is a method for making such a mirror.
Claims28
In a facility for generating technically useable energy by converting solar energy comprising at least one concave mirror and at least one energy collector, by which reflected sun rays can be intercepted and converted into technically useable energy, the improvement comprising:
- (a) the mirror being a stationary spherical mirror for focusing the solar radiation;
- (b) means supporting the energy collector such that it is brought to the theoretical focal point of the spherical mirror along its optical axis;
- (c) said energy collector extending along the optical axis in a direction toward the circumference of the spherical mirror and having annular zones stacked on top of each other as seen in the direction of the axis at the periphery of the energy collector, each zone having solar cells disposed at its circumference for energy conversion into d-c current, the peripheral surface of said annular zones defined by the solar cells being of conical shape in such a manner that the solar radiation reflected from any point of the concave mirror strikes the solar cells substantially perpendicularly;
- (d) means for moving said energy collector relative to the spherical mirror about an axis going through the center of the latter to follow the changing position of the sun;
- and
- (e) means for cooling said energy collector.
In a facility for generating technically useable energy by converting solar energy comprising at least one concave mirror and at least one energy collector, by which reflected sun rays can be intercepted and converted into technically useable energy, the improvement comprising:
- (a) the mirror being a stationary spherical mirror for focusing the solar radiation;
- (b) a vertical beam arranged along a diameter of said spherical mirror so that it can be rotated about the center of the spherical mirror to follow the changing position of the sun;
- (c) a first support arm disposed on said vertical beam supporting the energy collector such that it is brought to the theoretical focal point of the spherical mirror along its optical axis, said first support arm extending from said beam and further including adjustable cables suspending said energy collector from said support arm and permitting movement of said energy collector in the vertical direction;
- (d) said energy collector extending along the optical axis in a direction toward the circumference of said spherical mirror;
- and
- (e) at least two additional support arms supported for swinging motion in the vertical direction extending from said beam, said first support arm and additional support arms being arranged approximately at equal angular spacings.
