Water heater using cow dung and waste
In this project, the device consists of a copper pipe coiled throughout a container and filled with cow dung, copper pipe is filled with water and cow dung surrounding the copper pipe heats it up. cow dung (the waste product of cows) is used to heat water i.e. heat energy is obtained from cow dung. Heat is obtained due to the anaerobic bacteria (which grow in absence of oxygen) and heat up the surrounding. Water is kept in a copper pipe which is completely surrounded by cow dung.
