Scientists have developed a new technique for evaporative cooling using lasers. This method uses a laser beam to create a tiny area of low pressure in the air, allowing water vapor to evaporate and cool the surrounding area. This could lead to more efficient cooling systems that could potentially chill objects to temperatures below zero degrees Celsius. The research has implications for cooling applications from refrigerators to air conditioning, potentially reducing energy costs and environmental impact.

By using lasers to cool objects, scientists have found a way to make evaporative cooling more energy efficient. This laser-based evaporative cooling method could potentially chill objects to temperatures below zero degrees Celsius, allowing for improved cooling applications in refrigeration and air conditioning. This could reduce energy costs and environmental impact, making it a viable alternative to current cooling methods.
