Nanofluids in solar collectors

Nanofluids are very tiny particles made of special materials that are added to liquids like water. When these nanofluids are added to liquids, it changes their physical properties. In a solar collector, nanofluids act like a sponge. They absorb more heat from the sun and trap it until it's needed. This helps to make solar energy more efficient and makes it easier to turn sunlight into useful energy for powering homes and businesses. Solar collectors with nanofluids are much more efficient at turning sunlight into energy than other types of solar collectors.
