The Eco-cool water bottle provides cool water without electricity. he Eco-cool bottle has been designed in 3 layers. The innermost being the copper container, which shall actually hold the water. The middle layer consists of sponge made from khus (vetiver) and the outermost layer is a rubber sleeve. The base of the copper container has uniformly distributed micro perforations. Water seeps through these holes into the middle layer of sponge. As per the laws of thermodynamics the seeping water will lose latent heat to the atmosphere and cool the copper container. Copper being a good conductor of heat cools the water.
