Abstract: Extrapolating from structural work with textile or metal membrane roofs to cover silos, assembly halls and sports stadia, Schlaich, Bergermann and Partners, a structural engineering firm in Stuttgart, Germany, has developed a new type of solar concentrator using a single stretched metal membrane. Simpler and less costly to construct than previous methods, this concentrator could make possible small-scale solar power generation for much less than photovoltaic technology and at a cost comparable to diesel generators and also advance large-scale solar electricity generation. Solar energy use deserves the engagement of civil engineers and holds a large potential for future work in a wide variety of areas.
