Because You Asked For Dimensions

Over the past couple years I’ve heard several people asking for the blade dimensions of my stealth vawt. For this reason I’ve been planning to put downloadable/printable plans on my website that could be purchased for a fee. There would be SketchUp drawings for each of the components that go into building the Stealth VAWT. All of the parts from the bottom to the top. The cost of plans wouldn’t amount to much. And all of the income from the sale of the plans would go toward my many intended projects. I may still set up the plan thing when I have the opportunity. But for now I’ll just show you the blade components and give you the measurements in a video.

Before I get into that, I’d first like to say thank you to Thomas Jackson. He sent me $10.00 using the PayPal link he found in the description area under one of my YouTube videos. I don’t know which video he saw that inspired him to make that contribution but it’s awesome and appreciated. And the timing couldn’t be any better.

I’ve got $98.38 worth of materials sitting in an eBay shopping cart, and $125.23 of materials in a Metals Depot cart. Both batches of material are just waiting for me to complete the purchase. These are materials I need to begin the first of three major modifications I plan making to the Stealth VAWT and power pod. 

The new center tube design.

These carted materials waiting for my purchase are specific to a new item I’m calling “The Stick”. The stick is basically an adapter which would allow you to attach any alternator type PMA to the Stealth VAWT. A 4 inch diameter pulley at the base of the rotating part of “The Stick” will hold a flat belt which also raps around a 2 inch diameter pulley mounted to the PMA input shaft. This will essentially double the RPM of the PMA compared to the RPM of the turbine. I can’t wait to get started on this first of three modifications to my power pod.

Tilting and telescoping mast

Another modification is to the base/stand of the power pod which needs to have a much larger footprint for stability. It should also raise the turbine much higher. I want the mast to tilt up using a hand crank and I want it to telescope up 15 feet or more. It will still hold the solar panels in their current position when the mast is vertical, and the solar panels will lay flat over the base when the mast is down. This will put everything into a storm position.

Longer blades for a more centered generator

The third power pod modification will be to the turbine itself. I want the blades to extend down below the PMA putting the generator closer to the middle of the turbine. The blades will also be longer which will create more torque to the stick which will be driving the PMA.

Reciprocation to rotation gearbox

And now a word about my reciprocation to rotation gearbox. That project has been on the back burner for the past 38 years. I’ve shown my proof of concept model in a couple of my earlier videos. In fact my very first YouTube video from January 4 2009 highlighted the model, but I’ve never really explained it very well.

This little gearbox is used to convert reciprocal motion into rotational motion. When looking at the model you’ll see a framework holding a pendulum with wheels sticking out the sides of the frame. All of the stuff sticking out of the frame is there to show the motion created by the gearbox. But if you look closer you’ll see the tiny little metal box at the middle bottom of the frame. That’s where all the magic happens. Of course this is just a proof of concept model; the prototype gearbox will be much bigger as to hold much larger gears.

You may be asking, what could this contraption be used for? If you’ve ever seen a large body of water that has choppy or rolling waves, maybe you can imagine a chain of barrels hinged together end to end. Mounted at each hinge point of each barrel is one of these gearboxes driving one PMA, and as the waves roll under the barrels each end of the barrel rises and falls following the contours of the waves rolling under them. Power is generated from each PMA as they undulate in the chain, and feed power into AGM batteries mounted inside the barrels as ballast. Cable and anchor weights keep the power chain from drifting away, and a single power cable brings that electricity back to land. I’ve also seen videos of a wind powered water pump invented by Simon Farthing that I think is absolutely fantastic.

I believe this sail pump contraption could work just as well with my gearbox to make electricity. It might have enough torque to drive one PMA for each of the three output shafts of the gearbox or one even larger generator.

Using gravity to make electricity.

However my home environment is much different so the energy to be converted into electricity will need to be different as well. Tall trees and buildings block the wind and sun and most nights there is nothing to convert energy from at all. But that’s not exactly true. There are machines in service today that are still running after hundreds of years. These machines take advantage of forces that most of us take for granted. It’s an energy source that surrounds us constantly and impacts every moment of our lives. Without it, nothing on this planet would be the same as it is right now. I’m talking about gravity. Its gravity that runs many of the centuries old clock towers around the world. You raise a weight and control the fall of the weight through gears. Gravity can’t be bottled, bailed, boxed, sold or taxed. Why not use gravity as the world’s most abundant energy resource. I know, some folks might think I’m a bit Koo Koo by suggesting this. Hopefully I’ll live long enough to complete some of these projects.

And of course as I do, I will share them with you.

The biggest holdup in completing these projects is money. Everything has a cost! Even time has a value. Back in 2009 when I uploaded my first YouTube video I had dreams of making enough money off of videos to finance my projects. But over the past nine years, with over a half million views on my channel, I’ve only made about $1470.00 dollars. Hey that’s helped, but it’s a long way from what I need to complete these projects. So now I’m asking, if you find the blade measurements useful and if you intend to build your own VAWT based on my idea, remember its development had a cost. And know that many ideas are born out of personal need, not necessarily dreams of wealth.

So maybe you can find it in your heart to shoot me a couple bucks that I can use toward my next project. You can send any amount you’d like by using the PayPal link on the contributions page of this website, or you can contribute right now by clicking this link.
