The Sundolier robotic skylight from Boulder-based Sunflower aims to change all this by actively "pumping" natural light into interior spaces, illuminating areas of up to 2,500 square feet with a single unit.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
