A daft thought - solving world water shortage problems with air conditioning!

June 24, 2007 · Filed Under Thoughts 

We recently had an air conditioning system put in to help us survive the heat which hits Milan in the summer months. Now, I’ve noticed that our system manages to extract a litre of water or so after running for half an hour, and more water is extracted the longer the system is left running. This is no surprise when you know that Milan is one humid place in summer. However, this water extraction got me thinking, especially when my other half poured the water down the drain. What a waste, I thought. I did raise this with her, but she reckons that the water is not fit for anything. While I cannot disagree, I don’t really think this water would do the plants on our balcony much harm.

How about the plants in the local park? I wonder how much water is being removed from Milan’s atmosphere and whether this water could be used in some way instead of being wasted. Let’s take this a little further. Would it be possible to set up solar powered dehumidification/purification plants in places which suffer from water shortages? This water, at the very least, could be used for irrigation, and, after being purified, could possibly be used for washing and drinking purposes. Special plants could be set up in humid zones, and the water could be pumped, using solar powered pumps, of course, to arid areas.

Hey, I’ve just solved the world’s water shortage! Probably not, but, if someone is not doing this already, maybe it needs to be looked into by scientific types. Maybe Mr Bill Gates’ philanthropic fund could donate a few dollars towards research into this area.

Sorry, it’s hot here and, as mad dogs and Englishmen tend to do, I went out in the midday sun.

    Street trees and bioretention are effective ways to treat surface water and urban runoff, as well.
