“Sunlight in a tube/a” reports on the sort of environmentalism that we can and should all support. Replacing some of our florescent lighting with transported sunlight would I think be beneficial to more than just our pocket books. While it will, doubtlessly, be expensive to install such systems for the near future, over time the cost should pay itself off in decreased electrical usage. Additionally, everyone (except those who are allergic to sunlight I suppose (yes, such people do exist)) must prefer natural light to the horrid florescent lighting. Many people even prefer the “warmer” lighting from incandescent bulbs over florescent, even though florescent provide brighter light longer and cheaper than the incandescent bulbs do. How much better to have real sunlight./p
