A device efficiently collects energy from a moving source without having to actively track the source. The device includes a primary concentrator, a secondary reflector and a target position. The primary concentrator is positioned to receive energy from the moving energy source and to direct the energy toward the secondary reflector. The secondary reflector has a concave surface which is covered by a number of convex reflecting surfaces. These convex reflecting surfaces direct the energy toward the target position regardless of the relative angle between the energy source and the primary concentrator.
