Does the WIND·e20® Turbine actually work?
Absolutely. Prototype trials have verified that the Darrieus wind turbine concept is highly effective.
Does WIND·e20® make noise and kill birds like other turbines?
WIND·e20® is designed for on-site generation. Noise, like that of a horizontal turbine, would not be acceptable on the grounds of a school, business or in any urban setting. WIND·e is very quiet and the blades are shaped in such a way that birds fly around the turbine instead of right through it.
How big is WIND·e20®?
WIND·e20® is 105 feet tall. That means that we are ¼ the size of a normal horizontal turbine. WIND·e is shorter than an average water tower and has the same basic shape. Picture the water tower in your town and imagine Wind·e generating power quietly in a safe environment. If you can't quite picture it, maybe an illustration will help.
How much wind is needed for WIND·e20® to generate power?
WIND·e20® is able to generate power in low wind speeds. A class 2 wind (about 12mph) can power the turbine, but WIND·e performs best in higher wind classes.
Why is a vertical axis turbine, like WIND·e20®, better than a horizontal turbine, like “big wind”?
We think that safety, efficiency, availability, bird-friendliness and overall appearance are just the tip of the iceberg when it comes to choosing vertical over horizontal. We have a very detailed write-up about this very question here.
What equipment is needed to install the WIND·e20® Turbine?
WIND·e20® does not require much equipment on installation day! You’ll never see a “Wide Load” sign or extra vehicles trailing WIND·e’s truck. The entire turbine can fit on a drop deck semi-truck. The only heavy equipment required is a backhoe, and we’ll never need a crane, since WIND·e self-erects.
How does WIND·e20®’s self-erecting feature work?
WIND·e20® is controlled by a self-contained hydraulic system. The installation frame has its own generator, providing power for Wind·e to self-erect. Once the generator is fired up, the hydraulic system takes over and WIND·e opens its blades. It’s a breeze! Here's a one minute video showing the entire installation and self-erecting process.
How does WIND·e20® know when bad weather is coming?
WIND·e20® draws data from the National Weather Service. It tracks wind speed, weather systems, and even has its own anemometers. It can anticipate strong winds and bad weather before it gets to the machine, and WIND·e can shut itself down without human interaction in minutes. This makes sure that WIND·e is always protected from harm.
What happens when the wind changes direction?
WIND·e20® is omni-directional! Traditional wind turbines have to point directly toward the wind in order to generate power from it. With WIND·e, it doesn’t matter where the wind comes from, we get it! Our blades are designed to capture wind from any direction.
How difficult is it to repair WIND·e20®?
Since no cranes or big machinery are needed to repair WIND·e, it’s incredibly safe and easy to repair. Get that show “Turbine Cowboys” out of your head because WIND·e20® is designed around those obstacles. Our generator controls everything at ground level; there is no reason for anyone to have to climb to the top of the turbine. If a blade or bearing needs to be looked at, WIND·e can fold itself down to ground level and be repaired that same day.
How fast does WIND·e20® spin?
The average operating speed will depend on how fast the wind is blowing, but WIND·e’s maximum speed is 80 RPM.
I’ve seen YouTube videos of turbines going out of control and blowing up, can this happen to WIND·e20®?
Not likely. WIND·e20® has a redundant braking system, similar to that of your automobile. This system, paired with air brakes, gives WIND·e the ability to stop itself with a control system before any danger can occur.
Is WIND·e20® more or less safe than a horizontal turbine?
Our design is a lot safer than traditional wind. Since our blades are connected at two points, top and bottom, it is very unlikely that a blade will fly off or even become disconnected. Also, “Wind Turbine Syndrome” is a thing of the past with WIND·e. Since it’s so quiet and safe, the public will barely even notice it’s there until they get their utility bill.
WIND·e20® is not utility grade, so is there a way to see how it’s performing?
Information on how WIND·e20® is performing will be available on our website. You’ll be able to search by location and see the statistics. At some point, you may even be able to see a live feed of the turbine you’re looking for.
