Agastya Samhita, written thousands of years ago contains methods to construct an electric battery or cell, and also, how to utilize the battery to ‘split‘ water into its constituent gasses (Hydrogen an Oxygen).Modern battery cell resembles Agastya’s method of generating electricity. For generating electricity, Sage Agastya had used the following materials : One earthen pot, Copper plate, Copper sulphate, Wet saw dust, Zinc amalgam. A clean copper plate is put in an earthenware vessel.It is covered first by copper sulfate and then moist sawdust.After that put a mercury-amalgamated-zinc sheet on top of an energy known by the twin name of Mitra-Varuna.Water will be split by this current into Pranavayu (Oxygen) and Udanavayu (Hydrogen).A chain of one hundred jars is used to give a very strong electricity. Mitra is cathode , Varuna is anode , Pranavayu is oxygen, Udanavayu is hydrogen, Ghritachi is earthen ceramic beaker, Shata Kumbh is 100 cells in series to convert chemical energy to electrical energy, Apsara is water tight vessel..
