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.
