“As the world continues to experience a worsening climate crisis with record-breaking temperatures, scientists have developed a new, highly reflective glass coating that may help cool a rapidly warming Earth.

In theory, the coating — a slurry-like mixture of inexpensive glass and aluminum oxide particles — could reflect high amounts of sunlight off of the surfaces on which it is painted, such as roofs of buildings and roads.

Laboratory tests have shown it to reflect up to 99 percent of solar radiation back into space.”
