Parabolic Trough

A parabolic trough is a special type of solar concentrator that has a parabolic cross section (it is parabolic in two dimensions) but is linear in the third dimension. The result is that the parabolic shape is extended linearly to make a long reflector. The shape of the reflector causes sunlight to be concentrated along a line at the focus of the parabola, a line that runs along the length of
