Gallery: Sundolier Robot Pumps Sunlight Indoors for Powerful Daylightin...


What if you could light your entire building using no electricity, or artificial lights – but just the natural light from the sun? Conventional sky-lights do this well in certain types of single-story spaces, but are not very adaptable, powerful, and often have problems with excessive solar heat gain and heat loss. 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 1000-2500 sq. ft. area without any other sources.

    This sounds like a copy of the Himawari — sunflower in Japanese — a sunlight collecting system I saw exhibited at the Cooper-Hewitt museum in 1998.

    Interesting, but:
    – how do you light up on cloudy days or nights (especially for the northern latitudes)?
    – what is the ROI for an average house, office complex or larger building?
    – how does the device get power for the tracking motors?
    – what is the projected availability?

    “Inquiring minds want to know!”

    The tracker is self powered with integrated solar panels (see photo).
    The manufacturer is also developing a shutter so that you can install this unit in conference rooms etc.
    Rumor is that the Sundolier also does not work at night, so we will confirm that that is true.

    Three questions the article does not answer:
    1) How much energy (daily average) does the tracking motor use?
    2) Is the tracking motor solar powered?
    3) How does one “turn the lights off”, so to speak?
