Those who have traveled middle eastern countries might have noticed such tall cylindrical structures on top of buildings especially old ones. These are actually 'wind catchers', they as the name suggests, literally 'catch' wind to direct the flow of it towards the interior of house creating a uniform airflow throughout, thus maintaining the temperature inside at a very cool level even in the hottest summer times when the temperature in the desert can go well above 50 degree Celsius. A marvelous traditional architectural innovation by the old generation that effectively worked well and is still relevant. Now-a-days you will find many firms worldwide provide similar systems based on this unique concept to make our homes 'green'.
This system is very much environment friendly.
Modern technology modified the traditional concept by adding solar powered fans to direct the flow in a much more efficient manner. There are many technical things involved about the design of such wind driven air management systems.
Well, I am not going into the technical details of this awesome innovation. Those who would like to know more please check http://en.wikipedia.org/wiki/Windcatcher
I googled to collect more info about wind catchers before posting this, wow...there are effective methods to remain 'cool' inside our homes during summer. In Kerala, day by day atmospheric temperature is going up, humidity levels are rising and rains becoming less. It is high time to conduct more and more research to find out 'greener methods' to make our life better.
Be cool !
- Our ancestors, with limited resources were able to invent many things that made their life simpler. Wonder, how they could come out with such great innovations with very primitive technology at their disposal. Hats off to such creative minds !
