An carpeter named Ma Yanjun from Qiqiao village, Shaanxi province has invented a solar water heater built from hose pipes and beer bottles. The bottles are placed on a board in the sun and connected with hose pipes to let cold water to flowing inside. The water is heated only when the sun rays warm the bottles.



This invention was made for his mother because he did not want her to bathe in cold water in winters. When talking about mother's day i will love to gift such thing, and i think that she would be very excited. Since the price of a water heater is very exorbitant it was too difficult for him to buy a real water heater.

I am very happy when I see that the accustomed people accomplish so large inventions and extra saves the nature.
