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 the wind into a source of energy. With its Heavy Duty powder coated steel construction and features such as these you can expect many years of trouble free service:

• Its unique design keeps the rotor facing the wind until its self-furling action starts to kick in at 30-35 MPH effectively eliminating over-speed damage and the need for a brake system.
• The wind speed at which the furling action starts can be tuned to suit the alternator/rotor combination.
• It is the structure to which you mount commercially available alternators and rotors, including GM style Delco alternators from V8 air conditioned vehicles with frames 10SI and 12Sl converted for turbine use.
• Easily adapt other types of alternators such as an Axial Flux project with brackets made to fit the Turbine Tail™.
• Simple pipe thread pole mounting.
• Approximately 33 lbs. with alternator and rotor.
• Maintenance free POM bearings/bushings.
• Stainless Steel hardware.

The Turbine Tail™ needs these accessories to store usable energy:

• Generator & rotor.
• Charge controller.
• Dump load.
• Two 6V deep cycle batteries.
• 12V to 120V inverter.
• 3 Phase rectifier.
• Tower.

There are three options to purchase the Turbine Tail™:

• Purchase just the Turbine Tail™ and add your own generator and rotor: $450.00
• 500 Watt PMA (GM style permanent magnet alternator) with a 5 blade rotor: $695.00
• 1600 Watt PMG (permanent magnet generator) with a 7 blade rotor: $850.00

The graph below shows the results of testing the Turbine Tail™ with the the alternators above. As can be seen, they both start making voltage with a wind speed of around 5 MPH where it increases in a linear motion until the furling action starts and the voltage starts to drop. This exactly what we expect and want in a small turbine. Check out the test rig here.

These videos of the Turbine Tail™ show the furling action in testing and in high winds:

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' above ground level.
