SUNPORTAL " allows the best natural daylight to reach and illuminate any indoor environment, including deep plan building spaces that no other conventional daylighting systems can deliver."
It's terrific to bring natural light into places that don't have it. However it is better to design things right in the first place; this is no substitute for a window. On the other hand, commenters felt that this was certainly better than no natural light at all.
Ideally we would just live in our natural environment. Or at least live closer with windows and other simple things like going to bed when the sun goes down. But barring that this is better then what we normally have.
