One of the advantages of living on the shores is that you can enjoy the cool freeze if you are living on the east coast and off shore breeze if you leave near the west coast. But sometimes the temperature can rise at such places making it very hot in these coastal areas. When the temperature is high, people resort to modern cooling equipments like coolers and air conditioners. Though these equipments serve the purpose, they consume great amount of electricity.
However, by using simple physics the temperature around coastal areas can be controlled. By simply running pipes down the ocean floor containing cold water, temperature rise can be nullified. This cool water will cool the pipe and thereby the air flowing through it in to the city. Thus temperature in the city can be controlled without too much of additional energy. This is an energy efficient way of getting rid of hot atmospheric conditions.
