Wind Turbine Vertical
dnicholsoncole asked:
Wind Turbine Vertical at the SBE, Nottingham. there are trees nearby and a taller building adjacent. The horizontal anenometer is swivelling around like mad. Even the horizontal turbine on the tower nearby is unable to hold a good angle.

Google the name Windside and you’ll find all the technical information:
“Windside Wind Turbines are constructed of high quality durable materials to ensure free production of electricity for many years even in the harshest of environments. Their design ensures a minimum requirement for maintenance. When other turbines have failed Windside Wind Turbines continue to produce. A Windside Wind Turbine will probably still be working long after the purchaser.” Windside Wind Turbines are soundless 0 db

the VAWT is made by a company called Windside and the HAWT is a Swift. but these are european manufacture. there will be equivalents in the States. vawt has less vibration, so easier to fix to buildings.

sorry reading thread is a bit mad. isnt this suppose to be about wind turbines. trying to get technica info etc and start reading about weird religious freaks, Why dont you lot get a life!!! and stop preachin. Vertical Turbine Interest only. Now then how heavy is this and does it come in various W like 40W and 100W. What material is this made of. Can someone let me know wher i can get more info, the manufacturer or whatever. Thanks

Hi there, so do you make these? If so do you amke a 40W and 100W VAWT. What material is used? How heavy is it?

OK so there are advantages in both designs.

In terms of electrical efficiency, the hawt is much more efficient- the spinning object is lighter. with VAWT, the whole body has to turn, requires more oomph to get going. as one ‘cup’ is driving round, the returning cup is back against the wind, thus losing energy. However, quiet revolution turbines have a form of vawt that is more efficient once it has got moving. If the wind is turbulent and multidirectional use a VAWT as they keep turning even if the wind varies direction very rapidly.

So you’re saying that the VAWT isn’t as efficient as the HAWT?
April 12th, 2009 at 12:08 am
YOu can definently see the advantages over the traditional ones. the vertical probrubly has a bigger alternator and producing much more power.

This is the design I am using. Works fabulous.

no…. i was referring to the little white message in the video explaining about the vertical* generator and the metal wind direction shower thing….
April 18th, 2009 at 7:22 pm
You were, at first, challenging me as to whether the Anenometer was a generator. It is, in a tiny way, as it spins enough to make enough current tell the chip the wind speed. But it wont power the building.

sooooooo what are we trying to figure out here….. i think were on 2 different subjects

VA is Vertical axis, HA is Horizontal axis. The VAWT is a great idea in strong gusty winds, but it needs more to get it going. HAWTs get into trouble if the wind is gusty and variable.
April 20th, 2009 at 7:02 am
so which one is the VAWT? the fast one in the beginning or the fan one?
April 23rd, 2009 at 6:19 pm
No. next to the VAWT turbine is a wind measurer, its not a turbine. But a few seconds into the movie clip, the camera swings to look at the other turbine on the top of the stair tower, which is a Horiz axis turbine. Over the month I have watched this, i recognise that the VAWT is not so good, it needs so much more wind to get it going.

are you trying to call that wind direction teller thing (*metal windsock*) a generator?

Hello, where can you buy it? Or how do i make it? how much KwH in a year?
thnx

Both the power generator and the turbine have inertia that must be overcome to reach high speeds. Wind turbines have to be able to overcome inertia to speed up.
Angular Acceleration = Tourque divided by Inertia.
More inertia means you need more tourque.
So without tourque the turbine would take an extraordinary amount of time to get up to speed… in a vacuum. Turbines have to overcome A LOT of drag from the air to maintain their speed. That requires a force. Rotational force is TORQUE!

But, you dont need Torque in an Energy Generation device. You want speed. The higher speed the device rotates at, the more power will be output. The only reason you would want high torque, is if you were using the wind to run a mechanical energy output to do actual physical work.
Magnetic pickup coils do not have high friction, so no need for torque. Torque is Useless in this respect.

Bit hard to understand reading it isn’t it!
It was a reply to an earlier post, but hit the general post button instead of the reply to comment button.
Any clearer?

wtf r u talkin bowt?????
May 10th, 2009 at 9:20 pm
That just about sums up any organised religion for me matey.
History shows without a shadow of doubt that all four of those ‘atributes’, are part and parcel of these ‘enlightened’ souls.

Think of it this way. Is it easier to detatch a bolt with you fingers? or use a wrench? The wrench is easier because the farther the force is from the axis of rotation, the greater the tourque.
