How do plane windows dim?
Electrical current through gel However, the panes of the Dreamliner’s windows, manufactured by a company called Gentex, have a layer of gel in between them. When an electrical current is applied to the gel, it causes a chemical reaction that alters its opacity. The higher the voltage, the darker the gel becomes.
What plane is bigger 787 or 777?
The Boeing 777 series is generally larger than the 787 and thus can carry more passengers.
How do dimmable windows work on a Boeing 787?

How do Dreamliner’s dimmable windows work?
