Place a large array of fibre optic cable ends on the roof of an office, on a platform designed to track the Sun. Each group of cables is linked to an area of office which is usually dingy or lit only by a bulb (which creates a bad atmosphere - "sick building syndrome" etc). The cable could end in a diffuser,
which would be some array of mirrors inside a shade to protect the eyes of the workers. Thus sunlight would permeate even the darkest recesses of a multistorey city building, bringing cheer to the pasty hordes within. Pricy but cool. On cloudy days, well, it's back to electric light.

Hey! That didn't come up when I searched for it, it was just camouflage suits, pubic wigs and a couple of others. Well dang. [mfd] for me, I guess. Tcha. |

[PissOnYourFire] I hate to piss
in your Wheaties, but that's
just a tubular skylight. No
fiber optitcs involved. |
|
| |
As I've had this idea (and
detest the thought of any idea
lingering in yeasty limbo),
I'll toss a half-stale piece of
bread at [Nadir]. |
|

Maybe now [Nadir] won't look so
down. |

I always thought it might be possible to cover the entire
surface of a building with fiber optic "windows" so that
every office could have a window, in fact every office
could have a view since if you reconstruct the fibers in
the same arrangement you should be able to make out
the shapes made by the light when it hit the surface of
the building. |

Back in the good ol' days when they had wooden sailing ships, it was common practice to cut a hole in the deck and slap a prizm in it. that way, sunlight was reflected below decks. I guess this was kind of a precursor to fiber optic lighting. |
|
| |
And somebody patented an idea for running fiberoptics or waveguides from a single lightsource (headlights) in an automobile to the taillights and license-plate light, etc, so as to avoid all those so-costly extra lightbulbs. |
|
| |
The lighting for car instrument panels is often done like that; one bulb and a network of clear acrylic lightguides. |
|
| |
I've seen a fiber optic skylight before...The only place I can find that mentions it on the web is Sunstarskylights, but their website itself doesn't mention it, just one page that points to it. |
|
| |
The one I saw had a six lens array that followed the sun encased in a clear globe, focusing light on the cable and piping it where you wanted it. <searches again, and ooooos at a fiberoptic starscape ceiling...> |
|
| |
Found a couple of mentions of using them for 'daylighting'...<net.rummage> Bingo. A link appears. So, baked. |
|
| |
Somehow 1998 seems a long time ago. Sunpipe.com have a large tube so that's not fiber optics. Somewhere I read that there is a new type of fiber optic that allows light to diffuse out. That could be useful... Wonder what's up in the field. |
|
| |
Seems more like overcooked than baked. |

This company offers a system for daylighting, including tracking the sun: |

| |

|
| |
It provides 1100 lumens which is equivalent to a 100 watt bulb. How about a system that uses the sun during the day and a high efficiency light source during the evening? No need to change bulbs except in one central place, and the heat from the bulbs could be used to heat the building or vent to the outside if its already too warm in there. |

That idea existed for years. |
|
| |
But maybe you could salvage it with some Halfbakery Spin: |
|
| |
Billions of fibres linked by fibre-optics to a bug-eye on the roof. That way you can see pigeons landing on the ceiling. |
