10 foot diameter wind turbine blade set
[6611]
 $310.00 

DUE TO A BACKLOG OF ORDERS, WE ARE NOT CURRENTLY ACCEPTING ORDERS FOR THIS ITEM. Please Email us for more information on when this alternator will be available again. This 10-foot diameter set of 3 wind turbine blades is made from laminated Western Red Cedar. They are custom made to work with Otherpower.com's wind turbine designs. They come unfinished so that you can fit them to your project. Also included are 2 Baltic Birch plywood hubs to 'sandwich' the blades between. We normally use wood screws to put all this together.

Here is a picture of the blades as you'd recieve them. Since each set is custom-made, they won't look identical to this picture, but will look similar and functionally identical.

There are many options for finishing these. We usually just use several good thick coats of linseed oil and it works fine. It may or may not hold up well in more humid environments.

Here is a picture of an identical set of blades finished with linseed oil, drilled - and ready for assembly. You will need to finish your own blades, screw the hub assembly together, and balance them. We balance the blades by screwing lead weights onto (or near) the hub. Lead 'decoy' weights from sporting goods stores work nicely, you can attach them with wood screws.

Pictured above is a finished/assembled wind turbine with these same blades so you know what they'll look like. These are the same blades we fly on our 10' diameter machines around here, there are several in our community. They hold up quite well. When attached to an appropriate alternator we see them startup in very low winds. In 10mph winds we see about 100 watts. In 25 mph winds we approach 1KW. At this point I like the machines to start furling out of the wind, this protects the blades, the alternator, and the tower. Machines this large *must* have furling systems, the power of the wind is too much for any machine or tower to endure without it. To get 'real' usable power from average winds, we need a large diameter machine. I feel that 10' diameter is a good practical size, not too daunting yet still able to produce usable power in low/average winds. Keep in mind, the power from a wind turbine is directly related to the swept area, and to the square of the diameter. So a 10' diameter wind turbine should produce 4x the power of a 5' diameter machine. These blades are for the homebrew wind turbine enthusiast who wants a 'real' wind turbine and has the willingness to build/finish their own machine, but does not care to carve their own.

NOTE! These blade sets are custom made to order, and it may be 2 weeks OR MORE after you place your order until we can ship them to you. PLEASE call or email us before ordering with any questions about the alternator you need to match the blades to, or if you need a different size for a smaller or larger wind turbine.

The package these blades ship in is oversized for UPS, so they will show on your order with a shipping weight of 70 lbs. They weigh much less than that, but that's the rate UPS charges to ship them. We can not ship these over seas - the shipping cost is too high and it causes too many problems. If you order these and put in a shipping address outside the US or Canada we'll refund your purchase - we cannot ship these overseas. DUE TO A BACKLOG OF ORDERS, WE ARE NOT CURRENTLY ACCEPTING ORDERS FOR THIS ITEM. Please Email us for more information on when this alternator will be available again.
