Iv been kicking around putting one of those roof caps on my house with the big reflective tube that you run in the attic and then to a fixed light fixture to get some sunshine in my house, But it got me thinking, I could use sunlight in my kitchen my living room and my basement room, this would take three roof caps and would also get expensive not to mention I dont have the room between the walls of my house to "pipe" those massive relective tubes all the way down stairs, I dont know if im staying here for long but figure it will increase the resale value of my home,

Here's the question, Has anybody heard of fiber optics for this application? when you think of it it would be damn handy, I could run one big roof cap and split it three ways, Does anybody know if this has been done or does it have "attic fire" written all over it...?

Fiber optics have been used for interior solar lighting.

Google is your friend, Boomer. :)

For the most part every article on them they have been short lengths and straight shots to be effective.
Also what I know about fiber ops is the light source needs to be in close proximity to the end of the fiber. Unless the light source is very large in the brightness dept. I haven't kept up with the stuff since I let all my sign biz mags run out. But they all ways recommened a certain distance between the bulb and fiber end. Which depended on the brand. You might try this site if any they can point you in the direction you are looking for.

Cool, I added the word "fire" to your search and didnt get any imediate warnings, I really dont want a dish, I will look for a massive plastic bubble but it would have to be a big one, one thing for sure, this stuff looks very pricey...

Go cheap like I do. Use a heliostat.
