    3. Magnetic levitation is a nice principle. Apply it to a rotor: make a casing in which you put copper elements which create a magnetic field; in this cage you put the rotor with copper tips, which is spinned around. Then add a second cage under it which drives another rotor in a counter rotating movement. 4. The rotors are kept in place in the ...

    For a 5-megawatt turbine, the steel alone averages 150 metric tons for the reinforced concrete foundations, 250 metric tons for the rotor hubs and nacelles (which house the gearbox and generator), and 500 metric tons for the towers. This is FUD. The mass of construction materials pads the quote but is not a useful measure of environmental impact.
