Heliostat Fields: A Classical Approach to Analysis and Layout OptimizationShanley Lutchman (MEng) is a private consultant specializing in concentrating solar power, energy management and mechanical engineering design. In Heliostat Fields, Lutchman demonstrates, firstly, a heliostat field analysis method based on foundational principles of geometry and optics. He then demonstrates that common methods of heliostat field layout optimization can be improved upon by performing what he calls the "free variable method" of
