This case presents a simple conical solar concentrator designed to provide line-focused solar heat for water heating. The study addresses growing solar-thermal demand while avoiding the precise tracking required by parabolic dishes. It explains how conical geometry reflects sunlight toward a central axis, derives key design relationships for radius and focal length, and describes fabrication using galvanized steel and a mirror-like plastic reflector. The approach demonstrates a practical,...
