I'd suggest a window somewhere likely to get a lot of light. You could then use a lens to focus the light into a series of fiber optic cables. At the bottom end of each bundle of cable, you'd have a light source.<br />

You'd also have to add in the price for a window, lens, and the construction work you'd have to do, but it's hard to estimate that without knowing the exact installation. As a rough guess, I'd say you'd probably be looking at something around $1000, not including the fiber itself, for a decent-sized house.

Prisms have been used for lighting for some time now. The old sail warships had prisms mounted in the decks directly over the powder magazines. Daniel has the right idea--Fibre optics.<br />

I'm not sure its called prism then... but a cylindar will light up when light is introduced at one end without separating the light into it's wavelengths, I believe. I'm not sure what material (if there is a specific one) that it would have to be made out of. Definitely not an archetypal prism, just my lack for better description...

Also, if you're adding mirrors to concentrate light you could use a smaller diameter prism. But that could make really bright light. Might need the optical equivalent of a transformer to disperse or bring the light down to manageable levels.

Erik,<br />
<br />
The prism doesn't actually create light or energy for that matter. It just filters visible white light into its separate wave lengths. So instead of all this energy in one bundle you have 7 smaller energy bundles. What is the point of the prism? To heat a house? To provide more natural lighting? If you want to concentrate energy at a point you can look at what solar power towers are doing, effectively focusing all the light in a given area to a single point to provide a heat source…

If you want to concentrate energy at a point you can look at what solar power towers are doing, effectively focusing all the light in a given area to a single point to provide a heat source turning a liquid into gas for electrical generation. <a href="http://en.wikipedia.org/wiki/Solar_power_tower" target="_blank">http://en.wikipedia.org/wiki/Solar_power_tower</a><br />
<br />
For natural lighting, it might be plausible but there are already many architectural techniques that can increase the amount of light in rooms, merely by how you angle windows. Also the Milwaukee Art Museum has what essentially are moving roof walls that keep the amount of shade constant over pieces so they don't get extra UV exposure. A similar concept could be used to maximize light entry.<br />
<br />
In terms of cost, a normal prism is $7.95 (<a href="http://www.amazon.com/Learning-Resources-Acrylic-Equilateral-Prism/dp/B0006PJ12M" target="_blank">http://www.amazon.com/Learning-Resources-Acrylic-Equilateral-Prism/dp/B0006PJ12M</a>) and that's 4" long and say 1" wide (triangular area =0.5 in^2). For 2 foot diameter you would need 24"*24"/2=288in^2. Then divide by 0.5 for amount of prisms =576 prisms. That's just for a 4" depth. in a two story house with basement you're looking at about 40-50 feet long prism. So that's 600" (50'). 600"/4"=150 prisms deep. So all together you would need 150*576=86400 of these tiny prisms. But those prisms are probably severely marked up. Probably takes 25-50 cents to make. So you're looking at 20-45 grand for a giant prism. Do you agree? Disagree?
