I decided to make a “no-move” umbrella. I also try to copy some tree’s capacity :
-in winter they have no leaf, so the sun go throught and warm.
-In Summer they have leaf, they create shadow and so it create a fresh area.
The umbrella is think for : in winter always light and less early the morning(&late evening)
In Summer no light.
I also think about a system to keep the water in the bench.
