Last year a student who had graduated from the University of New South Wales innovated a washing machine which can use sunlight instead of water and washing powder to wash clothes. According to the student's design, the light in the house can operate powerful oxidants which can decompose filth into carbon dioxide and water. I think that it will be popular because it can save water, reduce the usage of washing powder, and there is the smell of sunlight on the clothes.
The most important effect of the washing machine is to save water. Saving water is very important issue. It is said that on 2025 if we only depends on the source of nature, that population of 7000 million of world face the pressure of water of shortage, even so the nation there are affluent water, such as America, China. If there are adequante solutions to the problem of water of shortage, we do not scare to take the bath and cultivate crops without water.
The second effect of the washing machine is to reduce the usage of washing powder.
We should use little washing powder owing to it causes not only the pollution of environment but also a variety of disease. The lakes in my country are in eutrophication because of a great deal of phosphorus. In addition, the composition of surfactant in washing powder will excite our skin and harm our health.
Another effect of the washing machine is that there is the smell of sunlight on the clothes. Having it, my clothes which there still are the smell of sunlight whether the weather is bad.
In conclusion, the washing machine helps a lot on environmental protection no matter how to save water or reduce the pollution of environment. I believe that it will become essential in our lives.
