solar windmill / solar streatlight

The core feature of this design is the panel
which will be converted into the shape of
the propeller when it gets dark.
It is designated for recharging from the
sunlight when the sun is in the sky and
working by the wind while the panel is
leaning at a 45 degree after the sun sets.
It is eco-friendly facility as it
can be recharged by using the
panel without other devices even
if the sun sinks down,
