A solar concentrator (10) comprises a spindle toroid-geometry outer solar reflector (12) comprising a first circular center region (13) having a first radius R1, a spindle toroid-geometry inner solar reflector (14) overlying the circular center region (13) of the outer solar reflector (12), comprising a second circular center region having a second radius R2<R1 and a solar energy receiving device comprising an outer receiving ring (R-12) having a first ring radius rl, that receives solar energy from the outer solar reflector (12), and an inner receiving ring (R-14) having a second ring radius r2 that receives solar energy from the inner solar reflector (14). |
