風車一問......................

NO, actually you are confusing about the wind energy and solar energy. If a wind mill is rotating by the energy of wind and it acts as a dynamo to generate electricity. If you want to collect solar energy by installing solar plate, the plate do not have to rotate, they can be installing in the wide open area to collect sunlight to create electricity directly.
As a result, you can imagine taht you build a wind mill and generate the electricity by the wind energy and install some solar plates behind the widn mill to generate the electricity by sunlight if no wind is blowing in some circumstances.

唔得既，如果你用鍚紙包住風車上的葉，個風車葉就一邊重輕唔平衡，就唔能夠再轉佐。
