History And Uses Of Wind Power As An Energy Alternative / Documentary Video

admin — Sun, 28 Nov 2010 23:26:42 +0000

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

New Wind Power – The Wind Belt Invention

admin — Wed, 20 Oct 2010 17:18:59 +0000

Shawn Frayne invented an inexpensive non turbine wind generator called the wind belt. I have no specs other than what you see on the video. I imagine it’s use on the roof of an electric car but obviously it can be used anywhere there is wind. The bennefit is that it is very inexpensive to build as opposed to a standard turbine wind generator.

The fan simulates the wind which moves the belt which moves the magnets through the coils to make electricity to power the clock and LEDs. I don’t know how much the output voltage is.

MWTT Maglev Wind Turbine

admin — Sun, 03 Oct 2010 08:26:25 +0000

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.

Solar Tower – renewable energy green global warming

admin — Mon, 03 May 2010 21:21:21 +0000

EnviroMission Limited (www.enviromission.com.au) produced this 5 minute video on the pilot plant in Spain. It is an older video (2000) but gives a decent understanding of the solar tower concept.

EnviroMission, Ltd. (US Market: EVOMY, Australian Exchange: EVM) is a renewable energy developer of sustainable “green” energy solutions for the energy market. EnviroMission aims to be one of Australia’s leading producers of clean renewable energy. EnviroMission holds the proprietary rights to Solar Tower technology, a large-scale renewable energy technology based on simple fundamentals of physics — hot air rises. Solar Tower technology has the potential to offer competitive renewable energy with equal reliability to fossil fuel generators.

A single 200MW Solar Tower power station will provide enough electricity to power around 400,000 households. The energy output will represent an annual saving of more than 1,960,000 tonnes of greenhouse CO2 gases from entering the environment when compared to brown coal emissions in Victoria. The greenhouse savings equate to the removal of approximately 500,000 cars from the road. The Australian Solar Tower project consists of six distinct phases, the first two of which (project optimization and pre-feasibility commercialization) have already been completed. The third phase (final feasibility), paving the way for the implementation of the next three phases (final design, construction, and commercial operation).

Installing Photovoltaic Solar Power at Home

admin — Fri, 16 Apr 2010 04:58:56 +0000

This vid shows the various steps in planning and having a company (Real Goods Carlson: http://www.realgoodssolar.com/campaigns/current/affiliate/?a_aid=blimylimey&a_bid=fbb2295d) install photovoltaic solar electric power in my rear yard in San Diego; definitely more challenging than a roof installation. My rationale for this: reduce my carbon footprint, buy / own my energy (like I do my house), help address CA’s energy shortfall and take advantage of the state and US government incentives for early adopters to save on the installation.
