A new siphon-based thermal desalination system can now transform salty seawater into clean drinking water—faster, cheaper, and more reliably than existing methods. Traditional solar stills, which mimic nature’s water cycle, have long been promoted as simple water purifiers. However, they face two persistent challenges: • Salt buildup, where crusts form on evaporator surfaces, blocking water flow.  • Scaling limits, as wicking materials can only lift water about 10–15 cm, restricting system size and output. A research team from the Indian Institute of Science (IISc) has addressed both challenges using a…
