USEFUL DISCOVERIES

Brief Description of PresentationThis presentation contains some creative useful inventions done in India and USA.

These discoveries can be used by us in our everyday lives and help make life easier for us.

Indian Discovery This paddling washing machine was discovered by

a women of Kerela named Remya Jose. It was invented in 2011. All those who wash clothes by hand have often wished for a washing machine that is cheap. But then, frequent power cuts (particularly in the rural regions) would make it difficult for one to use even a low-cost electric washing machine.

Remya Jose, then a class 11 student, thought of a simple, ingenious solution. She developed a washing machine which works with paddles of a bicycle.

Automatic Washing MachineIn 1858, Hamilton Smith patented the rotary

washing machine. In 1874, William Blackstone of Indiana built a birthday present for his wife. It was a machine which removed and washed away dirt from clothes. The first washing machines designed for convenient use in the home.
