Hi Bill,

Rain!  !  ! ...  !     !

Great ideas, but I am dubious about the energy  effectiveness of the Hybrid
solar system as the element (tubes) used to distribute the light is some
sort of super acrylic. Given how much is needed it would seem a lot of
petrochemicals are used to produce the product. Furthermore I question what
the 48" diameter collectors are made of and lastly how much light can be
produced. From the Fiberstars company and others we have used over the
years, I learned it is not easy to transmit bright light through fiber. Also
bear in mind the fiber has a dimension and limitation to turning radius.
I'm not a betting women but my money is on LED's! Save the fiber for display
and hard to reach installations or for where UV light is a problem.

Stay tuned.

Here are some C/NET photo galleries showing Sunlight Direct's hybrid
solar lighting systems and some fiber optics lighting fixtures from
Fiberstars now coming into the marketplace.

Hybrid Solar lighting, intended to bring natural sunlight inside larger
buildings, using runs of fiberoptic cables. :

This lighting system is similar to the "Himawari" ( = 'sunflower')
technology available in Japan but apparently not here in North America.

Fiberstars seem to be used to keep heat producing light sources away
from whatever you're lighting, as shown in them being used in dairy
products cases and seafood displays.
