REhnu’s molding process is unique in that it yields large glass reflectors of a paraboloidal (dish-like) shape, so that when pointed at the sun they bring the light to an intense point focus. Similar reflectors of back-silvered glass, but with cylindrical curvature to bring sunlight to a line focus, are manufactured in very high volume and at low cost to heat steam pipes in large solar thermal plants. Plants of this type have been in operation for decades and have shown that back-silvered glass mirrors are robust and have excellent mechanical and chemical stability. Rehnu’s reflectors will achieve similar longevity in operation. The UA and REhnu are now teamed in a DOE-funded program to develop the patented shaping process for high-speed production of similarly stable but molded, dish-shaped solar mirrors.
