apartment therapy changing the world, one room at a time

I haven't seen it in use but I remember hearing about it for the first time in the 80's for office buildings in Japan.

that is super cool! if its not sunny tho, I guess your fiber optic skylight gets dim...

Very cool but can I suspect that it's VERY expensive?

Yeah, they're not cheap. It would probably take years to recover the investment.

Sunspot, I saw this more for bringing natural light into a place that did not have it instead of relying solely on artificial light.

I did not see energy saving as the raison d'etre but rather the introduction of as much natural light as possible for someone who prefers it over artificial lighting.

In which case ROI would not be a factor for me.

Just offering another POV.

I was actually thinking about something like this the other day as a way of brightening up my condo's living room. Sadly, there are no dealers in the US and I am sure it is prohibitively expensive.
