Daylight without windows

New technology is piping sunlight into windowless rooms – South Korean and British scientists have developed patented technology that delivers “natural daylight to windowless spaces … without heat gain or loss.”

A mirror tracks the sun throughout the day, reflecting its rays onto a parabolic dish, which then focuses the reflected daylight into a small ‘light pipe’ aperture. The concentrated light then travels through a series of relay lenses “over any distance and in any direction”, according to the company. A diffuser ensures that light evenly reaches the desired areas.
