Welcome to the Solar Innovation Exchange, home of the Turbine Tail™!

The Turbine Tail™ is in a class of its own when it comes to converting wind energy into a source of energy for storage batteries:

• Its unique design keeps the rotor facing the wind until its self-furling action starts to turn it out of the wind at 30-35 MPH. This effectively eliminates over speed damage and the need for a brake system.
• The wind speed at which the furling action starts to turn the rotor out of the wind can be changed to suit the alternator/rotor combination.
• It is the structure to which you mount commercially available alternators and rotors. The simplicity of its design allows several different styles of alternators to be mounted, including GM style Delco alternators from V8 air conditioned vehicles with frames 10SI and 12SIl (check to see what's needed to convert).
• Simple pipe thread mounting.
• 33 lbs with alternator and rotor.
• Maintenance free POM bearings/bushings.
• Stainless Steel hardware
• Powder coated steel components.

The graph below shows the results of testing the Turbine Tail™ with two types of alternators:

• 500 Watt PMA (permanent magnet alternator) with a 5 blade rotor.
• 1600 Watt PMG (permanent magnet generator) with a 7 blade rotor.

They both start making voltage with a wind speed of around 5 MPH where it increases in a linear motion until the self-furling action starts turning the rotor out of the wind and the voltage starts to drop. This exactly what we expect and want in a small turbine. Check out the test rig here.

Here's video of one test run verifying the Turbine Tail™ action

Check NOAA for the average wind speeds in your area.

To get the most out of any wind turbine you need to be clear of obstacles and get it at least 25' to 30' above ground level.
