The Himawari Sunlight System is a solariffic way to light your house that won't add a cent to your electric bill. There's a solar collector you put on the roof (on left above) that tracks the sun all day, and distributes that light via fiber optic cable to any room in the house. You can get a variety of special fixtures that emit that light inside. There's one that looks like a sunflower (picture at right), but there are also other recessed fixtures and spotlights that look just like conventional lights. And, all the ultraviolet and infrared rays are left outside. It's the light without the heat. I am complete.
