Solar energy concentration device

A solar energy concentrating device for concentrating the intensity of solar radiation impinging on a solar collector, the solar energy concentrating device comprising:

• means defining a tapered truncated pyramidal-shaped channel for the passage therethrough of solar energy, said tapered channel defining means having solar energy reflecting planar walls such that solar energy which may impinge on said walls is reflected back into said tapered channel generally in the direction of the convergence of said tapered channel;
• a plurality of said tapered channel defining means being linearly connected to one another in an arcuate array defining a three dimensional arcuately shaped solar energy concentrating device having an outer convex surface through which solar energy enters said tapered channel defining means and an inner concave surface through which concentrated solar energy emerges from said tapered channel defining means to be focused on a collection surface spaced radially inwardly from said inner concave surface;
• and,
• said tapered channel defining means are oriented such that they taper in the direction from said convex outer surface toward said concave inner surface of said solar energy concentrating device.
