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.

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).

Many manufacturers are going into production or creating concepts with integrated solar panels in the roof or body of the car.

Although under normal use this will not provide all the vehicles power it will make a significant contribution when you factor in the decreasing cost of solar panels and the rising cost of fossil fuel.

Here are some examples:

Solar Toyota Prius:

Giugiaro Quantara concept:

and many more…

The Fisker Karma can already be ordered from the Fisker website – the first ones are scheduled for delivery in 2009.

The music theme is called ’sunshine’.

The wattage of the average car roof panel is around 250 watts. If you covered the entire car in solar film or panels you would get around 1000 watts or more.
