Although most places on Earth are covered with water, we still face the problem of water shortage, because we can not drink sea water directly. We must desalinate sea water before using it. And this sea water desalination machine is designed to desalinate sea water. It is mainly used by individuals in coastal areas lacking fresh water or in the case of a maritime disaster. It is very self-sufficient as it can float on the water and absorb energy from the waves to drive itself. When water is desalinated through it, the water will gather on the top and flow out through the pipeline. The only thing to note about it is that its filter core will be damaged and need to be replaced frequently. When the filter core fades, you will know it's time to replace it. However, the filter core is made of recycled materials.
