Breezy 5.5 is out there generating power at the rate of 2.1 to 5.5 kW pr hour. Your family is using power at varying amounts during the day and night. When you are at work, asleep, or just running the TV, a few lights, clocks etc, Breezy is providing power for your home and pushing excess power through your meter and building credit on your electric bill. Let's say mother is baking a cake, Breezy can't carry the load of the range on it's own so you'll need extra power during that time and that will take some of your built up credit away.

                           

It's Breezy's relentless day in day out push of power onto the grid that will provide credit on your meter. How much power? Up to 5500watt = 23 AMPS at 240 VOLT 60 hz (at 23mph wind)!!! That's enough to power the average home air conditioner, 18 amp 240 volt, and have about 30% left over for credit back to the power company or to power other things. A turbine generator, built with locally obtainable parts, not specific to wind turbines except for our controller. Nearly 100 people at the Kansas State Fair saw what we were talking about and now have their plans, the Book: Breezy 5.5, A Reliable Homebuilt Wind Turbine Generator, in their hands.

 

If you were to purchase an induction, grid tied wind turbine generator the size of Breezy 5.5 you’d be spending $15,000 to $20,000 with a payback of 10 to 15 years. Just a little out of reach for the average working man. You can build the Breezy 5.5 yourself with our plans and locally obtainable parts and you’d be spending $3,500 to $4,500 (we built 2 of them for around $3,500 ea.). That’s a payback of 2 to 3 years (results may vary with location, etc.).

The average daily wind speed in Kansas at 60’ is 15 mph and most large wind turbines including 20 kW machines have an output of around 3.6kw at that speed. Breezy 5.5 is right there with the big shots at wind speeds of 15 mph. In fact Breezy 5.5 beats most wind turbines including those large 20kw machines at wind speeds below 15 mph with a near linear output to 5.5 kW at 23-25 mph wind speed. How can it be that Breezy 5.5 can out perform those lager turbines?  It’s those 4 large wooden blades. They have a tremendous amount of lift at lower wind speeds and an equal amount of drag at higher wind speeds. We’ve designed Breezy 5.5 to operate within the range of the bulk of our wind speeds between 6 and 25 mph. And since the drag is offsetting the lift created by increased wind speed above 25mph there is no need for any pitch controls at all, eliminating failures that plague wind turbines with these kinds of controls.

If you build the turbine using the plans in the book you will be building a turbine just like the one in the picture on the home page. It will be mounted on a 6-inch pipe 60 feet in the air. Weighing in at nearly 1500lbs, Breezy 5.5 in no lightweight. You will not want to cut corners on the mounting structure or material sizes in any way, been there, done that.

The plans will show you how to measure and mark regular 2X12s purchased from your local lumber yard and using a handheld planer shape them into an airfoil/blade profile. You will be building the rotor hub and balancing the entire rotor assembly. The plans show you how to use a salvaged combine or truck axle, which will become the yaw assembly in which you will be mounting the bedplate and complete generator frame. After completing the tail-vane assembly you will be making the nacelle which will cover the generator, and the electrical enclosure where the control relays and micro-controller will be housed. The wiring diagrams are easy to follow and understand (remember when we used to paint by number, I like to call this “wire by number”). We have included two of these diagrams to help you better understand  the wiring (we even tell what color to mark your wire so that in the event you have trouble we will be better able to help you troubleshoot). The book has all the dimensions and details for building the 60’ mounting structure. The guy anchors, brackets, base footings and details for the cable truss assembly are provided. You will also be building the integrated gin pole that you will use to raise and lower the turbine for maintenance and inspection. You are given test and calibration procedures to insure proper operation prior to start up. Throughout the book where a picture wasn’t quite enough, we added simple CAD drawings and diagrams to help give better understanding of the task at hand.

We designed Breezy 5.5 from the homeowner/builder outward and we asked ourselves these questions.  How much generator does it take to offset the average electric bill, as opposed to how much power can we make?  How can we design this generator so that it is simple and still capture available power from bulk of the winds as opposed to capturing power from all winds?  How can we limit the power produced from the turbine so that doesn't overheat our generator in high winds and still not have to shut it down?  How can we design this generator with "non-wind-turbine" parts so that it can be built and maintained within a budget?  And finally, how can we make it strong enough to last for 20 years?  We answered all those questions with Breezy 5.5!
