ENERCON E126 – The World’s Largest Wind Turbine
This is the Enercon E-126, the first wind turbine with 6 MW rated power, rotor diameter: 126m (413ft), hub height: 135m(450ft). Two of these giant wind power units have been built for testing at an onshore location, Rysumer Nacken, near Emden, in the northwest of Germany. Here each WPU is expected to produce about 18 Mio kWh per year, enough for more than 4500 homes.

Energy from the Wind – Wind Turbines
I am fascinated by those beautiful, effective and environmentally sound modern wind turbines. This is the Repower MM92, rated power: 2000kW, rotor diameter: 92.5m, hub height: 100m. See also the record breaking 6MW E-126 from ENERCON www.youtube.com
Maglev Wind Turbine
www.maglevwindturbine.com Demo CGI for proposed 2GW Magnetic Leviatated wind Turbine. *Efficient Frictionless Power Generation with less maintenance, compared to HAWT. No oil change or replacement of the bearings, gears. Since, MAGLEV does NOT require such. ** Current bearing technology has forced wind turbine designers into horizontal spindle three bladed wind turbines. In this design the huge blades are connected to a spindle in the center. The bearings that support the spindle and control the pitch of the blades (which can be hundreds of feet long) see huge pitch-moment loading, some of which is manifest as torque energy that is focused through the center spindle. The target speed for the spindle is 18 or 20 rpm and the bearings holding the spindle are mounted in a huge casting which also contains a large gearbox stepping the speed up to 1800 to 2000 RPMs which allows for the proper surface speed relationship between the coils and magnets. It is necessary to invert or condition the current, which is expensive. This gearbox is full of many large bearings, gears and castings; for a 2 MW turbine the gearbox can easily weigh 30 tons. This gearbox needs to be mounted on the top of a pole more than 150 feet in the air and be able to support the turbine blades under full-force wind conditions. ***MAGLEV Power Generation, the pitch moment ratio is closer to 1-to-1 then the 100-to-1 as with a horizontal spindle design.
