Correct option is C
The smart window material developed by researchers at the Indian Institute of Technology (IIT) Guwahati in May 2021 allows for automatic climate control of buildings.
The smart window material can:
· Control heat and light: The material can regulate the amount of heat and light that passes through it by applying a voltage.
· Reduce energy usage: The material can help reduce energy usage and carbon emissions.
· Provide insulation: The material can insulate from heat and light reflected from neighboring buildings and structures.
· Be integrated with existing glass: The material can be integrated with existing glass windows or walls.
· Be used in vehicles: The material can be used in vehicles, locomotives, and airplanes.
The results of the study were published in the journal, Solar Energy Materials and Solar Cells.
