Wind Power Special Offer


Most of you know about my Wind Power and Battery Systems e-book and that it comes with the DC Motor Analyzer software bundled for $34.90. And, that alone is a great deal. I used to get so many questions about sizing the blades to match the motor, and what gauge wire to run, etc. After I bundled the software with the wind power book, all that changed. Just a few minutes playing with the software makes your life so much easier. So, I think it is an incredible value.

But, I just added 3 books and another computer program to the bundle for free. The free books and program really mesh with DIY wind power. Here is what I've added:
  1. Homemade Amp Meters
  2. Shunt Designer software package
  3. Welding with Batteries
  4. DIY Grid Tie
Homemade Amp Meters - If you are building a large wind power system and maybe solar power as well, then you need to be able to measure amps to and from the deep cycle battery bank. If you have a charge controller for the solar portion, then it will show amps going to the batteries. But, some wind power charge controllers (assuming you even bother to use one) don't even show amps to the battery. And how many amps is your big inverter sucking from the battery? If you have a 1200 watt microwave hooked to an inverter, then it is drawing 10 amps. But on the 12 volt side, that is 100 amps. Most volt ohm meters only go to 10 amps. So, you will need a shunt. This book shows you how to use different metals to make a shunt and you can read large current draws. In fact, this book shows how to make a shunt that can handle up to 2,000 amps, for just a few bucks.

Shunt Designer - This software package makes the complicated much simpler. You choose the metal you want to use, such as copper, aluminum, galvanized or stainless steel, etc., and then the thickness of that metal and you can computer the exact lengths to use to get the desired current carrying capacity.

You can also use it to figure out the resistance of stainless steel wire and "all thread" so that it can be used as a dump load for your windmill.


Welding with Batteries - This one is self explanatory for the most part. Building a large windmill may require some welding. My book doesn't require it, but my wind power book is meant to guide you into using whatever is available to harness the power of the wind.

In the welding book, you are shown how to find free car batteries and fix them to use as a powerful arc welder. Three car batteries can make 15 kw of power. At 240 volts and a 30 amp circuit in your house, you could only expect about 7 kw. You can double that with 3 car batteries. You can charge with solar. And it is portable. It could even be in the back of your truck.


Do it Yourself Grid Tie - This book is really new. In a nutshell, it shows 2 things:
  1. How to take an AC induction motor and use it on a windmill to feed the grid and turn your meter backwards
  2. How to take an AC induction motor and drive it with a DC motor to act as a grid tie inverter. Example - solar panel to DC motor that turns AC motor that feeds the grid to turn your meter backwards when the sun is out.
The AC induction motors can be found everywhere. In blow dryers and fans up to washers and dryers. You can also use large 3 phase AC motors and the book shows the "special" way to hook that up to normal household grid.

Anyway, I hope there is enough here to get you into the renewable and sustainable energy movement. And I hope the price is low enough so that the average person (especially in this economy) can jump in and make a difference.

Later,
Richard
