The original "Stanford Torus" design of a wheel-shaped space colony had an offset mirror angled to reflect sunlight onto mirrors set around the central hub and then outward to the ring. Elysium has no such arrangement and sunlight simply shines directly to the interior of the ring. This is completely impractical, as Elysium rotates (about every 6 minutes). This means that location around the habitat would have an ongoing series of periods of "day" and "night", each lasting only 3 minutes, which would be extremely disconcerting for the inhabitants. In addition, Elysium appears to have its rotational axis pointing towards the Earth, and as it orbits the Earth that would mean that (a) it rotates with respect to the Sun, and so the amount of sunlight and its angle will be continuously varying, and (b) during each orbit it will spend time in the Earth's shadow and not receive any sunlight at all.
