http://www.skyalgae.co.cc/ How the turbine works: Rotatable shutters mounted on a circular disk automatically open when directed into the wind, irregardless of the wind’s direction. Pairs of upper and lower shutters are geared together. The lower shutter acts as a counterweight to the upper shutter. The bottom shutter opens in the downward direction and its weight helps to lift the upper shutter in the upward direction, as the wind applies an opening force against both shutters. When the shutters reach the vertical position, stops prevent them from opening further and the force of the wind is transferred from the open shutters to the circular disk. And the circular disk is attached to the vertical axis for power output. The circular disk, shutters, and outer vertical axis rotate together. The outer vertical axis is mounted via bearings over an inner vertical axis that is stationery.

The shutters are blown closed by the wind (no stops in the opposite direction) as they reverse direction during their rotation and move into the wind on the opposite side of the wind turbine. When the wind is not blowing, the shutters open by gravity because the lower shutter is weighted to be slightly heavier than the upper shutter and it therefore can cause the upper shutter to open via the force of gravity as the two shutters are geared together. Wind blows against the open shutters and the open shutters with stops apply a force against the disk, but the open shutters with no stops (opposite side going into the wind) merely close due to the force of the wind (not applying a force against the disk) and the wind turbine begins spinning no matter what direction the wind comes from. Operation of the turbine is remarkably quiet as compared to the appearance of the video due to biasing members that absorb the shock of the opening and closing and provide useful energy output.

The twin rotor venturi turbine charges 12 volt batteries on my dog kennel. The batteries power lights and a 400 watt inverter. The turbine is mounted to the mast that use to support the wires from the grid.
The turbine demonstrates the ability to supply green energy in an urban enviroment. There is very little noise from the machine and it does not require guy wires to support the unit. A turbine like this could power a garden shed or garden lighting.

This lizard does this every day and really seems to like it. Sometimes he gets thrown off and is right back up there again. We have thousands of them, they eat lots of bugs.

ANOLIS CAROLINENSIS has been dropping in population due to other sub-species.

Take a look at my new forum on my website. Welcome!
Design of the generator based on Tesla Technology.

This wooden model of the generator was built by enterprising group of Canadian enthusiasts in order to check possibility of general useing revolutionary new electric circuit and revolutionary new design of a rotor and a stator of the generator.
Materials:
8 NdFeB rare earth magnets grade 40,
12 coils of copper wire 20AWG,
plywood, fiberglass, copper tubes.

Why do we do that?
We want to prevent a fuel and energy crisis in the World.
And we want to save our beautiful planet of Greenhouse gases.

Our business proposal for Canadian and international entrepreneurs is very simple. We are looking for an investor who wants to invest funds in renewable energy sources in Canada.

Why do we need this capital?
We would like to buy land in windy area in Canada.
And there, we would like to build a wind power station with our revolutionary design of electric generators.
And then we would like to sell available electric power to customers (including your interests!!!).

If you interested by the idea above, please feel free to email us your wishes at:

VOAvideo asked:

Wind power is one of the fastest growing forms of alternative energy in the world. More and more, wind power mills are seen in the countryside, in large wind farms and for the most part, away from city life. But a new form of wind power is now designed to work in an urban environment. VOA producer Zulima Palacio has the story. Mill Arcega narrates.

The braking mechanism that limits the speed of the wind turbine broke during a storm in Denmark. This was the outcome. 02/22-2008.

Bonus info:

-The tower of the mill was 60m high
-Wind speed was probably around 30 m/s
-You can see a truck at the base of the mill, but nobody was hurt. The mill had been evacuated 400m in each direction.

Windterra asked:

Windterra’s Vertical Axis Wind Turbine (VAWT) is designed to operate in micro-winds as low as 3 metres/second (10.8 km/h, 6.7 mph) and can withstand winds as strong as 53 m/s (190 km/h, 118 mph). The optimal output of 1 kW is reached in wind speeds of 11-12 m/s (39 – 43 km/h, 24.6 – 26.8 mph).
