Use snow to chill the summer!

In a major part of the world, we have four seasons, which means we need heating in the winter and cooling in the summer. In the old time, people used to save deep snow and ice in shadow and use it for the summer time. However, this old tradition is gone. We have chill and perhaps piles of snow in the winter and hot climate in the summer. If we can manage save this huge amount of energy for 6 months, it can be the source of our heating and cooling throughout the year!


(Remaining of snow in Borås in the middle of March. In this place snow is piled to a height up to about 10 meter during the winter, and smells down during the spring without any use)
