The device, meant to be a home appliance works by drawing air through filters to remove dust and particles, then cooling it to just below the temperature at which dew forms. The condensed water is passed through a self-sterilising chamber that uses microbe-busting UV light to eradicate any possibility of Legionnaires' disease or other infections. Finally, it is filtered and passed through a pipe to the owner's fridge or kitchen tap. It claims to be able to produce upto 12 litres of water per day.
The mill ceases to be effective if the relative humidity is below 30%. However the device has a built in computer that increases its output at dawn when humidity is highest. It is not clear how much energy the device will consume, but the web site claims that the device is "energy efficient''. Well, dont try to buy the device now - the company's web site says the online store will be open in 2009.
My engineering 'fundas' are not good enough to comment on whether this device will work effectively. Will some 'real enginners' stand up and comment on this device? I would like to know:
(a) Is this techncially feasible?
(b) If so, how come no one invented it till now?
