The 1940 "World's Fair" was opened by light from the distant star Arcturus passing through a photocell to activate somethiing.

The device I propose uses the light from the most distant stars to provide "solarpower" at night or on cloudy days.

A polyhedron is a 3-D extension of polygons, such as squares, hexagons, etc. Consider a surface section of a hollow polyhedron, such as would fit in a semi-sphere. The faces of this structure are Fresnel lenses to magnify light from stars. The faces are placed so as to point to, say, the 20 "major" stars. The structure bears some resemblance to the facetted eye of a fly. Using the device which allows a telescope to remain fixed on a stellar object while the earth rotations, each facet continues to point to the same star.

Have you ever heard of the "Olbers Paradox": "Why is the night sky dark?" In 1826, the German astronomer, Heinrich Olbers (x-y), noted that, if stars are distributed evenly through "infinite" space, a steller disk should cover the sky light it as in the day -- even burn the earth to a cinder. (Actually, in 1744, Jean Phillipe Loys de Cheaux this question. But it was Olbers that grabbed attention.)

However, the night sky is dark. Why?. Various explanations over the years have been advanced to explain the noneffect. One of the most discussed is that the effect of "the expanding universe" is just enough to counter this burning effect.

Now, magnification of the light of major stars might have a cumulative effect.

If 20 facets is not enough, the facetting might be increased.
