MAGLEV Wind Turbine
Friday, December 10th, 2010 at 5:57 am
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.

wind force mobility “kazaguruma”
Wednesday, December 8th, 2010 at 4:45 am
”Kazaguruma” is a mobility using wind force efficiently. It is thought that spreading electric vehicle will reduce the amount of CO2, but by generating electric will produce CO2. So we focused on natural energy to reduce the environment load. We are using air reswind powerd dynamic lift of wind power. While wind blowing from the sideways, dynamic lift becomes strong and it can save its electricity. We are assuming that the wind blowing in one direction such as the shores is the fixed area in use.

Blade Design for Wind Turbines (Part 1)
Friday, December 3rd, 2010 at 1:29 am
Presentation about the challenges of blade design for wind turbines given at Windpower 2009, Chicago,wind powervented by Siemens Wind Power, the IntegralBlade® technology manufactures wind turbine blades in one piece using a closed process. The glass fiber reinforcement is laid out to dry using a special molding arrangement with a closed outer mold and an expanding inner mold. After completion of the lamination of the glass fiber, the epoxy resin is injected under a vacuum. Following this injection, the blade is hardened at a high temperature while still enclosed in the mold. Once the blade is hardened, it is removed from the outer mold, and the inner mold is collapsed with a vacuum and pulled from the blade. The result is a complete, seamless blade finished in one process. More: www.powergeneration.siemens.com
