The concept of energy saving and environmental protection Solar water purification ball: Solarball can purify 3 liters of water a day. ConceptNet has also introduced many water-saving and environmental-friendly creative designs, but the solar solar water ball (Solarball) brought by Monash University's Jonathan Liow is relatively simple and easy to implement. Simply put, this is a plastic ball that can collect solar energy 360 degrees. It can be roughly divided into upper and lower parts. The lower part is the sewage area and the upper part is the clean water area. The lower part of the sewage is evaporated by solar energy. Then, the water purifier in the upper part condenses into clean water that can be directly consumed. The designer said that the overall system's thermal efficiency translates into high levels, providing at least 3 liters of purified water per day. For some areas with serious water pollution, this 3 liters of water will sustain people's lives.
