Over the last couple years, many people who had watched my ‘Building the Stealth VAWT’ video asked me the question, “How much”? Well, that answer depends on whether you need parts or the whole thing. Unfortunately I haven’t had an accurate answer until now. The first Stealth VAWT was made strictly as a proof of concept experiment. The next two were made as an exact matched pair in order to compare the performance of a WindBlue low wind PMA to a 48 volt Freedom PMA. I used less expensive rivets and bolts than I would have if I was building the things for someone else. Stainless steel fasteners are always preferred over aluminum rivets and plated nuts and bolts. There are also weak spots where I expected eventual failure. I had a good idea of what I needed to do to strengthen those places but chose not to worry about them for various reasons.
Of course now that one VAWT unit has been ordered, I’ve purchased those higher quality fasteners and made those necessary upgrades on my first customer purchased Stealth VAWT. After all, I want anyone who buys my products to have worried free use of my products for many years to come. To borrow a term from Ron Popeil, I’d like you feel comfortable to “set it and forget it”.
Better fasteners are only one aspect of the VAWT upgrades. In my original design, a small tab of aluminum is the only thing holding the blade to the blade mounting ring. Even though I have not seen a blade break free from the blade mounting ring of any of my VAWTs, this is a known weak spot and needed to be addressed before making blades for a turbine being purchased. Now each blade has an eight inch long 1/8 X ½ inch aluminum bracket that I make as reinforcement for that tab.
The third improvement not only adds strength to the blade, but (in my eye) makes it just a bit more aesthetically pleasing. I have added one more bend to the vertical blades. This ¼ inch wide outward bend on the outer edge of the vertical blades should help keep those long edges straight through most any thunderstorm nature might throw at it.
Prices will change eventually, but if you watch this video and are still interested contact me through my website.
