Abstract: My invention will be used to cut down utility costs in homes and buildings, be a burglar deterrent, as becoming opaque is one of the features, and replacing car windshield sun blocks as well as blinds in school, buildings, homes, etc. The photosensitivity is manipulated through voltage input. In NYC in January for example, persons would set film to dark mode to activate the darker tint to absorb the heat of the light, whereas white or mirrored mode would be deactivated; visa Versa during the summer in NYC. This is meant to be green as it will cut down utility costs immensely and by being able to manipulate the voltage manually, you set how sensitive the photosensitive film is from no voltage manipulation to opaque.
