SAVES THE BIRDS AND BATS since slow-moving. DOES NOT OCCUPY A WIDER LANDSCAPE since the turbine can be very tall. MAY BE LOWER-COST since it may use timber and other cheaper things. ELUDES HURRICANE FORCE since the V-type folding blades automatically close. NO FIRE since well-cooled. HELPS WIND-ENERGY COMPANIES since it is FREE FOR ALL.
