title: 'Using Two Parabolic Troughs to Simulate a Paraboloid'
description: 'It is possible to use two parabolic troughs, curved in perpendicular directions, to bring sunlight to a point focus as does a paraboloidal reflector. The incoming light strikes one of the troughs, which sends it toward a line focus. The second trough intercepts the converging light and focuses it to a point. This diagram shows the principle. Compared with a single paraboloid, using two partial troughs has important advantages.'
