The future won’t be either black or white—it will be black and white. In the field of architecture and design, people are often use to choosing between form or function. In the future, as a result of advances in nanotechnology, this age-old debate will become less relevant. As proof, I submit this article discussing a new technological advance that will allow the roof of the future to be both black or white—depending upon the temperature outside. (On cold days it will be black to absorb sunlight and on hot days it will turn white to reflect sunlight and keep the building cooler.) Depending upon your perspective that might either be a cool idea or a hot new area of interest.
