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.
We all know that optic fibres can transport light over long distances and are flexible enough. A single optic fibre is too thin to transport a huge amount of light but suppose a whole bunch of optic fibres were used to form a... say one inch (or more) thick cable, then would it be possible to transport a high intensity of light through this cable? This needs to be experimented.
If successful, then we can have a thick cable that runs from the terrace of the building to the room where the lighting is needed. The bright sunlight can be focused on the cable using parabolic reflectors or optical lenses. A transparent heat shield can be placed just before the cable starts, to absorb excess heat. At the receiving end, a special spherical glass unit with multiple miniature prisms can be used to evenly disperse the light like a bulb. For every 'bulb' there will be one cable. The cable will be flexible enough to be routed in a neat way.
If this system works for even 50% to 60% of total office lighting, then this will mean a huge saving on electricity bills for commercial establishments as well as residences and will be a clean, maintainence-free source of day-light energy.
Regards,
Rony.

Hi,
Gmail filtered this mail as "Spam" LOL gmail is smart. (LMAO) Sorry I'm not answering your question or anything. But I just *had* to share this :P -Akshay
I'm a gamer but i dont know what u mean by Gaming Zone Configuration.

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.

Good idea. May be we should experiment. Actually, if you have observed on the streets there are people selling pods of OC fibres with bulbous ends. They do EXACTLY what you just said and they are quite efficient at it.

I haven't seen the bulbous end ones but I have the hand held torch based one and the decorative table piece one that opens like a huge ball of tiny dots, like stars in the sky. It should not be very expensive as the distance between the terrace and room is less than a hundred or few hundred meters, whereas optic fibres are known to be efficient over distances of 100s of kilometers. :)
