Energy Creation 3 KW (VAWT) Verticle Axis Wind Turbine

It is estimated that small scale wind generation -- together with other forms of microgeneration -- could provide 30-40% of all the UK's electricity needs by 2050*. And, with price trends for crude oil continuing upwards, it is currently projected that the cost of small scale wind will be competitive with fossil fuels by as early as 2010.

Small scale renewable energy technologies, such as small wind turbines generate clean and renewable energy with no harmful emissions, and can thus help to reduce a significant proportion of the UK,s carbon dioxide emissions. There is an increasing amount of interest and support for these technologies potential from politicians, industry and the public alike.
Although the UK has excellent wind resources, the location of any wind turbine is still crucial to the output that can be expected from it. Ideally, a wind turbine would have no obstructions between it and the prevailing wind direction (usually south westerly).

Obviously, in an urban environment some wind turbulence is inevitable unless the turbine is sited well above any surrounding buildings. Historically people have been put off utilizing wind turbines in urban environments because turbulence from surrounding buildings will affect a wind turbine's ability to generate power. This is the primary reason for opting for a vertical axis wind turbine, the design of which does not require wind from a consistent direction to continue producing power. In comparison a horizontal axis wind turbine has to physically rotate into the wind every time the direction changes, wasting valuable resources. Other benefit's of VAWTs over HAWTS.

Vertical axis turbines have been in use for many years, but with the advancement of design and materials they have become a major contender in the small scale, and larger scale wind energy marketplace. The VAWT has a vastly reduced amount of moving components, which means that there is reduced risk of any major component failure, a problem that HAWT's with larger gearboxes and generators have to overcome with extensive and costly maintenance. VAWT's have no need to be directed into the path of the wind to generate electricity. The reason for this is that the rotor hub sits on top of the generator, because having a blade design that will work with omni directional wind flow, they work at optimum performance when in turbulent air.

Hi

Nice work!

Can you please say what is the pitch angle used?

[chapellkarina]

great talent .. very entertaining .. thanks

[archsticks]

small scale?? along with?? what about Meglev!?

[itsandbits1]

sorry bout getting nit picky but even the vawt does not perform at optimum in turbulent air. it works better than hawt does by far but it still for optimum needs a single direction wind supply; especially the lift type like yours

[SimpleWindSolutions]

Nice. Care to share data?

[rnewhouse57]

isn't thier some "resistance on the return side of this? If so, couldn' t you put a "half Barrel" around it that would swivel with the use of a wind like a horizonral wind turbine uses to stop the wind from blowing against the "return half" as it comes back around to catch the wind agian? ( for lack of better terms)

I don't know much about phisics but wouldn't that be beneficial?

trader pierre has a perpetual motion design

Dude! You appear to have a screw loose upstairs.

That's cool though! After all, you manage to have internet access. Right?

[fakiir]

Thank you. thats one of those things you "know" but are not sure of the exact order of the variables so you dont want to quote it.

another issue to stepping a supply voltage up and down are the small losses to resistance in the transformer, in the form of heat. so even if you can transform the output to run a motor or some such, you lose some of the power generated in the first place as heat, that energy has to come from somewhere in order for the system to sustain, or it stops.

of course, fanning the sails falls into Newtonian territory, (equal and opposite reaction, eg: fan blows wind against sail by thrusting toward the front of the boat, the sails power wants to pull the boat forward, but cannot because the fan is pushing the boat backwards.)

perpetual motion, AKA: 100% efficient closed system, is not possible. if it was possible, any alleged perpetual motion system would start instantly with no external impulse as soon as the last bolt was tightened. impossible.
