Fibre Optics Bring the Sun Indoors

Sunlight Direct is using fibre optics to bring the light from outside and transmit it inside. Their 1.2m diameter solar dish will light 90m² inside — minus the harmful UV rays — rendering a more natural lighting feel, which can be hybridised with florescent and possibly LED lighting to provide a constant light level, though the tone changes with the level of light outside. The GPS-based sun-tracking mechanism uses very little energy
