We went to solar
exhibition which named intersolar North America on 7/12.
There are three
floor at exhibition.
First floor is
about solar panel. There are many panel designs such as flower or hover panel.
Each design show
me the new way to collect and transfer energy.
Second floor is
about inventer. inventer do heat exchanging type ventilation.
Third floor is
about parts which constitute mechine.
I saw many things, and feel the real technology using now.
