When I first saw the Solatube my first thought was, "Why have I never seen this before?" How much simpler could a product be? It is basically a tube that goes from your celing to your roof, catches sunlight, and pipes it down to brighten your home or office. Forget discussing incandescents or CFL's, I would much rather use a light source that uses zero electricity!
The obvious reason I've yet to see many of these is that they are much easier to install when a house is being built, and not that easy to retrofit. I would like to think all home-builders (if they still exist) who claim to build "green" homes have the Solatube in their arsenal. If they don't, why not? If you're building a new home or an addition to your existing home, how much have you thought about natural lighting?
To be honest I really don't know much about this product, but I'd love to learn more. Have you had any experience with it or do you know anyone who has? Why aren't there more of them out there?
One of the biggest reasons new energy and water conservation technologies aren't more popular is that the average homeowner just doesn't know they exist! This blog's goal is to find the best technologies out there, prove they work, and help spread the word.
