Smart glass window

Singapore has developed a "smart glass window" that can eliminate heat. Summer reduces cooling costs. The "smart glass window" is a multi-layered electrodeization window. Two thin layers of tungsten oxide and vanadium oxide electrolyte are added between the two layers of glass, and an ordinary battery wire is connected to the window case. When the battery is energized, the chemical composition between the glass produces electrical pulses that change the color of the glass as the sun shines. When the sun is strong, the glass is blue and 95% of the sun is reflected. When the sun is weak, the glass is colorless and becomes transparent. All light can enter the room.
