AI functions with microchips that requires a high amount of electricity and this produces intense heat. This is why they have to use water to cool it off; If they do not have other method for cooling, the AI system will fail because of overheating. It is like saying that AIs drink water. So there is a high demand for water in countries with a high rate of AI facilities. This water demand is mostly used by processing AIs. From my research the questions you ask a GPT AI uses a minimum of 10 ml to 250ml of water, for 1 to 20 questions. Imagine the amount of water it consumes and the number of questions you ask per hour. The water consumption per question varies so there is no fixed figure. The full meaning of GPT is Generative Pre-trained Transformer. It is a special kind of Ai that processes questions and generate human like answers.
