Spray-on "smart glass" blocks heat and light - transparent color film
Scientists in the United StatesS.
DOE designed a spray
On the nano-crystal window coating, the amount of heat and light passing through it can be adjusted by electronic control.
The researchers described the science behind the innovation in nature.
Basically, it includes very conductive materials that can absorb both heat and color change when current passes through them.
Thin transparent film coated on the coating will provide the required voltage.
According to the researchers, when the materials are combined, they can block 50% of the heat and 70% of the light.
The two are independent of each other, so on hot, sunny days, for example, they can keep the room cool while minimizing the need for light-making.
The team is working with a startup in California that is working to bring the product to market.
Production will be very expensive now, they say, but they are trying to solve the problem ---
And hope energy conservation can help offset costs.
