Sunlight Direct Hybrid Solar Lighting

Sunlight Direct Hybrid Solar Lighting Sunlight Direct's hybrid solar lighting system is an interesting new technology that essentially pipes sunlight into buildings via fibre optics. The system makes use of a GPS aware light collector unit that sits on a building's roof. The unit utilizes GPS along with an onboard processor to orient the light collector to within .1 degrees of the sun to maximize efficiency. The system monitors a room's natural light intensity via photosensors and, during cloudy periods, compensates by increasing the traditional fluorescent or incandescent lighting output.

Here's a YouTube video of the product in action.

Since 30% of electricity used in the US is for lighting (the number grows to 45% in retail), the product would theoretically have a huge potential market, especially commercially. The commercial version will light about 1000 square feet at a cost of about $10,000. That may sound expensive, but that's really only because that's a lot of money. However, if the (hard to believe) claims in the video of retailers seeing a 40% boost in sales when using natural lighting is true, then the $10,000 is largely irrelevant when viewed over the long term. According to the video, the company plans on launching a residential unit in 2008. No word on pricing...

Here's an interview with Duncan Earl, CEO of Sunlight Direct, that's also worth a look.
