Indian Scientists have developed a groundbreaking new device that allows smart windows to change color without requiring an external power source. Unlike traditional electrochromic windows that rely on electricity to adjust their tint, this innovative technology harnesses energy from ambient light or temperature changes to shift between transparent and tinted states.

This advancement could revolutionize energy-efficient building designs by reducing reliance on artificial lighting and air conditioning, ultimately lowering energy consumption. The self-sustaining nature of these smart windows makes them ideal for homes, offices, and vehicles, paving the way for a more sustainable and cost-effective future.
