Active Sunlight Collector unit

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.

    very innovative.

    I just wonder the ability and extent of such light. The initial reflect/feed/focus lense isn’t all that large. What kinda lumens are we talking at distances. I could think this very useful for the many sprouting living building erecting, futherly lighting the interior. High density growhouses could also put this to great use, maybe even a subsurface greenhouse with the right hard coating on the relay lenses. I might have to intertwine this into my evolving biosphere designs, perhaps in the top center of the dome in the keystones center…

    I’ve been waiting for this. So many apartments are designed with interior rooms, bathrooms and en-suites with no available daylight, requiring the electric light for use all through the day. The Sunportal system could supply a low level light that would suffice for most simple activities, cutting the building’s energy footprint.

    Fantastic idea. I’d see this as a complimentary light system in low light areas. Not neccessarily bringing light to total darkness, but lighting up stairways and corners, doorways and such. Ultimately making public areas more comfortable and safer. Would work especially well with automatic artificial light system, where sensors detect the amount of natural light and regulates the artificial light accordingly to keep the total amount of light steady at all times.

    If cheap enough, I see no obstacles for using this to lower the need for artificial light, thus lowering the electric bills.

    although an exceptionally useful application to further extrapolate comfort in deeper areas of buildings – what about the human need for comfort satiation by merely … looking out the window. without that … one is still in the caves of man-made central or under ground building areas; no matter how enriching the light. far from a naysayer to any progressive creation – i wonder instead, with the pc capable of gehry-style manipulations – surely we can somehow still retrofit/build structures of a depth and occupance needed for ideal densities.
