Bladeless Windmill Generates Electricity Efficiently
Mekaro Akita Co., has developed a windmill that uses cylinders rather than propeller blades to efficiently generate power. The five 10-meter-in-diameter cylinders individually rotate to produce sufficient lift to spin all of them in a circular motion, thereby generating electricity. An attached electrical unit provides the initial power to turn the cylinders. [movie]
