      The mountain of salt will have a mass of at least 3.5% of the total amount of water you produce. It will be a lot more than that if you only use some of the water and let the rest evaporate. For example, Israel produces more than 1 million tonnes of fresh water per day. That's 35,000 tonnes of salt, or 16,000 cubic meters -- enough to cover a football field to a depth of 3 meters -- every single day.
