AN Indian (印度的) boy invented a washing machine that does not need electricity to work. The 15-year-old, Darshan Kolhe, uses a bicycle to keep spinning a barrel to copy the movements of an electrical washer.
The machine actually consists of a barrel and a bicycle. The barrel is connected to the bicycle with a chain. Clothes, water and detergent are put in the barrel, and ‘riding’ the bicycle will clean them. To dry the clothes, one only needs to ride it with the hatch open.
At least 300 million households in India do not have access to electricity, so the machine would help all those people if it is mass produced. The invention has been praised by the Indian Institute of Technology Delhi.
