Gigantic Fan

I wondered at the gigantic fan, It looks cool and beautiful, It spins with the force of wind, Why the fans are planted on the open space? In the open space They are planted as the biggest trees, I wished to have such fan near my home, Will my dreams come true? Yes, they are the biggest fans, I would cease my work to stare at them.. I wonder how they fixed it, Still they don't care about my sight... I learned about the wind mill When I reached middle school, The biggest fans are wind mills; I still laugh at myself, How innocent and naive, I was?
