In theory, it seems silly to pay for light bulbs and electricity when natural sunlight is free, and now this eco-fantasy is becoming a real possibility. Developed by EcoNation and installed on the roof, Lightcatcher is a sun-tracking solar dome that uses a mirror and technology-based system to generate green energy, bring light indoors, and mitigate temperature fluctuations. The sensors and motorized mirror and lenses harvest sunlight, reducing energy costs and environmental impact eight times more than solar panels, according to EcoNation. The company also claims that Lightcatcher can provide sufficient light for up to ten hours per day, using only 1-3% of roof surface area.
