1. Nicholson and Carlisle first generated H2and O2by water electrolysis in 1800, and in 1874 J. Verne wrote “Water decomposed into its primitive elements, and decomposed doubtless by electricity, which will then have become a powerful and manageable force . Yes, my friends, I believe that water will someday be employed as fuel, that hydrogen and oxygen, which constitute it, used singly or together, will furnish an inexhaustible source of heat and light . I believe, then, that when the deposits of coal are exhausted, we shall heat and warm ourselves with water. Water will be coal of the future.” From: Verne, J.The Mysterious Island; France, 1874.
