1. A compound parabolic concentrator (CPC) arrangement comprising:
a transporter supporting a plurality of CPCs each configured to receive sunlight, wherein each CPC comprising:
a concave reflective bowl defined between a bowl rim and a bowl apex that comprises a bowl aperture;
a fiberoptic cable extending from a fiberoptic inlet end at the bowl apex to a fiberoptic outlet end, the fiberoptic outlet end configured to emit the sunlight received at the fiberoptic inlet end from the bowl aperture, the sunlight emitted on a granular surface;
an internal cover volume defined within a cover that extends from an internal cover top to a cover rim;
a cryogenically cooled surface within the internal cover volume, the cryogenically cooled surface configured to be cooled by cryogenic liquid,
the fiberoptic outlet end extending into the internal cover volume;
a light concentrator lens configured to receive the sunlight at the bowl apex and concentrate the sunlight into concentrated light that is transmitted through the fiberoptic cable.
