Answer

Concave mirrors are used in solar furnaces, because concave mirrors are the only type of mirror that reflects light in toward a single focal point. A flat mirror does not have a focal point. It does regular reflection off all of its points. The light will reflect up and away from the focal point of a convex mirror !
