Jessica displays the Tri-Nado Elite rotor
The latest in a series of power rotors
This rotor develops a little over 2 horsepower at around 22 mph.
If you are wanting to build a "gear up" system you can
go up to 1:6 ratio depending on the generator with the Tri-Nado
Elite. This system
has a rotational start speed of 2.3 mph and runs all the way down to
If you have a high output low rpm generator, or you have a
generator that needs a few hundred OR even a few thousand rpms to produce power,
you can gear this rotor up and it will crank out some serious
voltage and amperage in a modest 10 to 15 MPH wind.
This unit comes with one Laser cut hub made from a solid piece of 3/16th steel,
along with the bolts, nuts, and washers for assembly.
TSR test results.
Just in case you do not know what TSR stands for, it
is how may times faster the tips of the blades run in respect to the
Rotor size - 7 foot
Wind - 10 mph times 88 = 880 feet per minute.
Rotor speed - 300 rpm's
times 21.98' circumference = 6594 Rotor tip speed in feet per
TSR - 6594 feet per minute rotor speed at the tips divided by 880 wind speed = 7.49 to 1 TSR.
