The Sunportal system tracks the sun and collects light throughout the day with an “Active Sunlight Collector” – and it’s able to do so even on cloudy days. The collector redirects the light into an “Ultra Sunlight Concentrator”, which channels it into the aperture of a small light pipe. The concentrated sunlight can then be directed anywhere over any distance through a series of “Sunlight Relay Lenses”. Sunportal says that because its technology uses “the latest IR-cut coating technology, there is no heat loss or gain associated with the transmitted daylight,” which reduces heating and air conditioning costs.
Sunportal currently has dealers in Europe and North America. Systems have already been installed in South Korea at a pumped-storage plant, a steel mill, and a pedestrian subway.
