ABSTRACT:
An adjustable window tinting system for producing varying degrees of tint in a window to thereby limit the amount of light and heat pass through a window. The device includes two panes of glass, a darkening mechanism which separates and merges the two panes of glass, and an opaque fluid that enters between the two panes of glass at various thickness depending upon the amount of separation of the two panes of glass. The various degrees of tint are thus attained from the various thickness of the opaque fluid, varying from substantially opaque to transparent.
