Concept of power supply by itself
Power generationnew power from nature
Heat insulationsave the expense of air condition
Reduce the power supply from city power
Reduce the warm crisis of earth

Benefits
(1) Generate power
(2) Heat isolation
(3) Summer time: save air condition expense
(4) Winter time: save heater expense
(5) Transparent : save light expense
(6) UV transmission 0%: protect people and furniture inside
(7) See through 10% from inside: see the sky but not so harsh to the eyes
(8) Not see through from outside: keep private
(9) More good looking than current solar roof
(10) Look sky, cloud, moon,….
