light pip e schemes recently, and show one here developed by Veronica Garcia Hanse n, a PhD student from the Queensland University of Technology in Brisban e We quote Veronica: Most systems use complicated and expensive sun tracking systems. Our sol ution has no mobile parts, and is completely passive, therefore reducing operation and maintenance costs. We realised that a simple device known as laser cut acrylic panels, woul d passively redirect sunlight inside the pipe. This reduces the number o f light reflections along it, thereby increasing the performance.

Nobody should have to sit 30 metres from a window for half of their waking life. The images here are oppressive with or w ithout natural light. jpg after light pipe So points to Veronica for a clever solution to the wrong problem- Lets de mand better working conditions with windows and fresh air and views, not piped air and piped light and Microsoft backgrounds as the only trees a nd plants that we ever see.
