A man created a coloring color for his home and saved on electricity
A resident of New York Joe Duset told CNN that he came up with a paint that was changing color so that the walls of his house were absorbed by more sunlight in winter and reflected in the summer. According to him, the invention allows him to save on electricity, softening the consequences of climate change.
When Dusets thought about what color he wants to paint his house, he began with an experiment: he printed 3D models at home and painted them in different colors. He found that in winter inside the black model the temperature was higher by 4 degrees Celsius, and in the summer inside the white model was 6-7 degrees cooler.

“The answer was not whether to paint it black or white?” The answer was: “In winter, it should be black, and in the summer - white,” he said about the results of the study. - It is unrealistic to paint the house twice a year. I began to think: “Surely there are other ways to solve this problem?”, Duset said.
The man said that he remembered his childhood hobby with rings that change the color “by mood”, and that already at the age of seven he realized that not emotions, but “some kind of chemistry” influence the color of the rings. According to him, when creating a new paint, he used a similar mechanism. He also added a protective supplement to the composition so that the coating does not collapse in the sun.

At a temperature below 15 degrees, its paint looks black, when warming it becomes gray, and from 25 degrees-begins to move from light gray to white. The inventor believes that its paint can become a “breakthrough technology” for residents of temperate latitudes, but it will not be needed by residents of regions, where the climate is constantly hot or cold. According to his assessment, the residents of houses painted with its paint could save from 15 to 30 percent of electricity costs, including heating in winter and air conditioning in the summer.
