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.

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

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.

Making hot water using unmodified trash bags (which were later used for their intended purpose). You can’t beat the ROI on these DIY solar collectors. In cold, cloudy or windy climates, an additional layer of plastic can be put over the top to hold the heat in like a greenhouse. Some day I will replace these with an inclined box and a toilet valve filler, complete with shower head.
