All-weather friendly cooling technology works without mechanical compressors or chemical refrigerants, and generates drinking water 

Imagine a technology capable of cooling buildings and homes in an economical and eco-friendly way, even in the most challenging of climates. That possibility might become reality soon by a team of researchers from the National University of Singapore (NUS). These engineers have pioneered a new water-based air-conditioning system that cools air to as low as 18 degrees Celsius without the use of energy-intensive compressors and environmentally harmful chemical refrigerants. This game-changing technology could potentially replace the century-old air-cooling principle that is still being used in our modern-day air-conditioners. Suitable for both indoor and outdoor use, the novel system is portable and it can also be customised for all types of weather conditions.
