Without water, life itself would cease to exist. Alongside air, it is the most essential element for survival. Water constitutes more than 60 percent of the human body weight, while proteins account for only 18 percent, fats 15 percent, minerals 4 percent, carbohydrates 2 percent, and vitamins less than 1 percent. However, only a small number of individuals are aware that water can also serve as a source of electricity—another crucial element in modern life. “We all need electricity,” said Von Hernandez, a leading environmental activist. “It is vital – it powers our lives, runs our hospitals and schools – we need it for every aspect of our lives.”
