<< If you've ever blown up a balloon or pulled at a pair of pantyhose, you may have noticed that the more the material stretches, the more transparent it becomes. It's a simple enough observation: the thinner a material, the more light shines through >>

<< For buildings and windows that automatically react to light, you don't have to spend as much on heating and air conditioning (..) The problem is, these materials are too expensive to produce for every window in a building.
