Summary:

According to the video, a new discovery by MIT researchers could revolutionize our understanding of evaporation and have a major impact on desalination, weather prediction, and even climate change. The traditional understanding of evaporation is that heat from the sun heats up water molecules, causing them to move faster and eventually escape as vapor. However, MIT researchers have discovered a new phenomenon called the photomolecular effect, which shows that light can directly cause water to evaporate without heating it. This process is much more efficient and can potentially evaporate four times more water than heat alone.

This could be revolutionary for desalination.
