Abstract
A solar collector utilizes an inflated tubular film which concentrates sunlight onto a solar receiver. The film incorporates refractive elements in a pattern which focuses light in one or two dimensions to create foci in the form of lines, spots, or other shapes. The film may be replaceable. The film may include layers of material to optimize optical, structural, thermal, and durability characteristics.
