- arghwhat 3y agoA "bladeless fan" is just a ducted fan where airflow is redirected through small openings at very high velocities. As extracted wind power is proportional to the area you extract wind from, using such small opening would be uselessly inefficient even if the air velocity was high enough to make the turbine spin. I suppose it would still be "bladeless" to have a giant duct - larger than the diameter of contemporary windmill blades - that redirect flow to a turbine in the base, but that would effectively be a giant bird blender. So no, not really.
