The Tree of Life is a big-scale device that seasonally reserves rainwater resources and wind power resources in a reasonable manner.
During the rainy season, the concave side of four leaves collects rainwater at the largest size and reserve pure water when the rainwater is filtered while flowing through the middle part. The store water on the bottom is drinkable.
During dry season, the three leaves on the side spin 90° clockwise and rotate around the trunk with the wind, which in turn transforms wind power to electric energy and reserve.
