The Whisson Windmill is a device that extracts clean drinking water from the atmosphere. It does this by drawing air in past a fan, whose blades are cooled by refrigerant. Because the blades are cooler than the air, water in the air condenses into a liquid, which is collected. It was invented by Max Whisson, a retired medical specialist who lives in Australia. [1]
The Whisson Windmill has been cited as one possible method of dealing with climate change. Dr Whisson said of the device, "The essential principle is that more wind is used for power than for water supply. In other words, the area of power turbines is greater than the area of turbines leading to water harvest. This is all made much easier by the invention of a new kind of wind turbine or 'windmill'. The amount of water available in the air is for all forseeable practical purposes unlimited. The bottom 1 kilometre (in the atmosphere) alone contains about 1,000,000,000,000,000 litres of water and that is turned over every few hours. The 'Whisson Windmill' or Max Water From Air device will make it possible to get adequate water anywhere at any time, drought or no drought." He also stated, "A special feature may be that installation in drying lakes and wetlands would restore these threatened ecosystems." In addition, he said, "Isolated dry communities of course, where people must carry water in a pot on their heads to survive could be transformed, and our new little company is committed to providing some of the first units to such communities in need."
