To understand
wind generators you must understand a little about electricity and physics. To the novice
it may appear to be as easy as attaching some blade to a car alternator, couple
that to car
batteries and your done. Sounds easy until you begin to understand that a car alternator
is built to operate at high RPM (2000 to 5000 rpm) and does very little at low speed. Then you find that car
batteries are made to surge a high current and recharge. Nothing like what would be needed
for a wind turbine. And what about the blades? They must be balanced properly or the
unit will be destroyed by vibration in a very short time.
Component Level Diagram For Electrical Wiring Info Click Here! Every part of the system must be considered carefully. For example the battery rack seems simple. However the batteries may need venting and have requirements to reduce corrosion. One brand of battery which has been found to work well is Optima. Optima batteries are expensive compared to conventional car batteries and are generally found in car with high end stereo systems as they can support the constant drain of the loud base system. Large scale systems require gear boxes which needs regular maintenance, It is interesting to see the utility companies are just finding out that ROI (Return on Investment) is not the short period they had hoped for. So when a big company makes a bad judgment who will pay? .
Wind tunnel turbine test All of the Total Tech Corp completed wind turbines as well as most kit products are tested in a wind barrel tunnel for the important factors such as vibration, speed control and balance. Balance includes front to rear as well as blade balance. More info. |

| Most of the books on the web that proclaim they will show you how to build a wind turbine do show you how to build an experimental unit. If you buy plans from another vendor and they say to mark a 2x6x6' board at a full 6 inches. You got a bad set of plans since a 2x6x6' is not exactly 2x6 so how many blades have they actually cut? Most of the books do not touch on the hard issues such as how to get the power down the pole. Some suggest getting wire that will stand a lot of twisting so as the turbine turns the wire can twist. Well you know how well that works with a phone cored. In our booklet we provide actual solutions. |

For people living in colder climates the wasted heat recovery can be used for heating of your home providing you with additional savings. Battery racks need proper ventilation and regular attention to perform as required.
