It seems to be a good concept. Though I am not an expert in this area, I see few practical difficulties. 1) Optical fibres are lit using coherent and powerful source of light like laser or LED. If the source is not coherent, issues like dispersion etc crip in. I am not sure how effectively we can use sun light as it is not coherent. 2) We can use parabolic reflectors, but the size of the single fibre is 1/1000th of a milli meter. ( thickness of a human hair.) Therefore, we need miniature reflectors. Not difficult to produce these days, the whole assembly( reflectors + fibres) has to be on a sigle board. 3) I have a show piece that uses optical fibres. But the light it produces is not much. I do not know how we can use fibre to glow a lamp. Even if we use multiple fibres, I do not think it will produce enough light.

Hello All,
In the concrete jungles that we live in, the amount of natural daylight that is available to every room in our buildings is negligible. This results in full usage of electric lighting even during the daytime. Due to this, our electricity bills shoot up and the commercial establishments pay the maximum price for this.
Huh? Is this a repost of a Ronald Piquepaille article posted on slashdot? Please _attribute_ your original source.
