History And Uses Of Wind Power As An Energy Alternative / Documentary Video
Wind As An Energy Alternative / Educational video. Department of Energy. Produce by the Solar Energy Research Institute. Wind: An Energy Alternative. This program looks at the history and uses of wind power, used for centuries by humans to move boats, pump water and grind grain including discussions on efficiency, problems in the urban environment, experimental systems and windmill use across the United States. Producer: Department of Energy. Creative Commons license: Public Domain.
Surprisingly good short film about wind energy. What makes it valuable is the interviews with Marcellus Jacobs (a builder of wind turbines in the 1930s) and Ted Finch (whose efforts got the concept of net metering legally acceptable in the US). It’s interesting to note that one of the people listed in the credits, Paul Gipe, is still active in the industry. He’s now a leading author on the subject. His website is http://www.wind-works.org

The Combined Power Plant – 100% from renewable energy
http://www.unendlich-viel-energie.de
The secure and constant provision of power anywhere and at anytime by renewable energies is now made possible thanks to the Combined Power Plant. The Combined Power Plant links and controls 36 wind, solar, biomass and hydropower installations spread throughout Germany. It is just as reliable and powerful as a conventional large-scale power station.
The Combined Renewable Energy Power Plant shows how, through joint control of small and decentralised plants, it is possible to provide reliable electricity in accordance with needs. The Combined Power Plant optimally combines the advantages of various renewable energy sources. Wind turbines and solar modules help generate electricity in accordance with how much wind and sun is available. Biogas and hydropower are used to make up the difference: they are converted into electricity as needed in order to balance out short-term fluctuations, or are temporarily stored. Technically, there is nothing preventing us from 100 per cent provision with renewables.
The Combined Power Plant is an initiative of the companies Enercon GmbH, Schmack Biogas AG and SolarWorld AG, and is supported by many partners from the renewable energy sector.

MWTT Maglev Wind Turbine
http://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.

Kitegen Stem – High Altitute Wind Energy
The Kitegen Stem is an italian developed power plant that is rated at 3MW. A 27MW kitegen Windpark (9 stem units) is under construction since Dez 09.
1MW installed will be about 4 times cheaper than conventional windturbines with a capacity factor from 50-85% depending on location an operating high (800-10.000m).
The Stem could be operated offshore or on a ship.
Heres much more information on the project (with comments by the Italien inventors).
