How much did the solartube cost (to buy and install) if you don't mind me asking?I sometimes think that our ideas of cost may be too restrictive. If you shell out on a renewable product today which you know will do the business for many years the knowledge that you will not have to worry about spending money on the energy in the future is a value (the reduction in anxiety if nothing else) over and above whatever you might have to pay for it in the future. Don't know if that makes sense.
Example. We built an extension in our house which left our kitchen really dark. The lights needed to be on any time we were in the kitchen and they used a certain amount of electricity. Anyway, my solution was a product called a Solatube, basically a device which captures sunlight on the roof and pipes it the 17 feet down to the kitchen below. I will not recover the cost of the product in the reduced electricity but I have peace of mind knowing that my kitchen is bright without it having to cost me money in the future.
