- Solar Dishes such as the one shown uses a paraboloid shape to focus the incoming light into a single collector.
Basic Description
The geometry of a parabola makes this shape useful for such solar dishes. If the dish is facing the sun, beams of light coming from the sun are essentially parallel when they hit the dish. Considering the construction of a parabola, these incoming beams would be perpendicular to the parabola's directrix.
