How is clean drinking water made from salty seawater? In this episode of Hidden Horizon, we'll explore seawater desalination from start to finish: why 97% of the planet's water is undrinkable, how reverse osmosis works, and why entire countries are literally drinking the ocean today. You'll learn why you can't simply boil the sea to get fresh water, and how two engineers in 1959 revolutionized the industry by refusing to heat water at all. We'll peek inside a real desalination plant, trace the path of a single drop from the seabed to your tap, and uncover a hidden detail that has dramatically reduced the cost of fresh water. We'll also discuss the price the ocean pays: what brine is, why finished water is deliberately "spoiled" before being delivered to your tap, and what oranges have to do with it.

📌 In this issue:
— Seawater desalination in simple terms
— Reverse osmosis and membranes
— Desalination plants in Israel, the Persian Gulf, and other regions
— How much energy is needed to extract fresh water from the sea
— Ecology: brine, water intake, and remineralization
