Direct sunlight via fiber optics?

Hello all,

I'm building out a reef tank and after reading several posts and books
it seems the two biggest issues are nutrient export and lighting.

I've recently stumbled across a new company that is offering something
called sunlight direct. Essentially it is a dish that one mounts
outside that collects lights and feeds it inside your home via fiber
optic cables. It's essentially a solar collector.

In their words the idea is to "To capture sunlight and distribute it,
using optical fibers, into the interior of a building to provide
premium quality, controllable lighting capable of reducing energy
consumption."

Their website is http://www.sunlight-direct.com/overview.html. Does
anyone see a problem with this idea? The downside is that during the
winter months (at least in the US anyway) the hours during which the
sun will be up and the time during which I'm home doesn't coincide as
much as I would like but I hear that fish (and really all animals)
become healthier under the sun.

Any thoughts?
