Pumping Sunlight Into Homes
ByronScott sends a snippet from Inhabitat that begins "What if you could light your entire building using no electricity or artificial lights – but just the natural light from our favorite star, the Sun? Enter the Sundolier, a powerful sunlight transport system that's like putting a solar robot on your roof to pump sunlight indoors. The manufacturer claims a single Sundolier unit can provide enough light to illuminate a 1,000-2,500 sq. ft. area [93-232 sq. m] without any other sources." The company's website is a bit thin on details, such as what happens on cloudy days, or how many days of sunlight per year on average are needed for the device to perform acceptably.
> Wow ... "increase the speed of learning?"
Actually that is an important point. Most artificial light is so poor that it hinders whatever you try to do. It is well known how to produce better lighting, but it is just not done. When was the last time you experienced lighting that can adjust the color temperature, for example? That is quite an essential feature to keep your day rhythm working properly, and it has been shown to improve learning results significantly.
