2010 National Wind Exposition
 
The 2010 National Wind Exposition was held at the Dallas, Texas convention center, and not only occupied nearly all of the more than 2 million square feet of the facility (upstairs AND downstairs!), but also in the parking lot north of the Center. Unlike many events where we have a booth, the National Wind Exposition gave US a chance to walk around and learn for a change, and there was ample to see, inside and out.

Deceptively quiet. This photo was taken the day BEFORE the Expo opened.

A massive wind turbine blade occupied much of the front of the Convention Center.

Wind turbines on display .. from little ones...
2010052425.png
... to bigger ones ...
2010052404.png
.. to really BIG ones! This is the generator from a 660 kW turbine. Three blades attach at each set of metal tabs with the very LARGE holes.
2010052429.png
And how does a large turbine connect to the power lines? With a really BIG transformer, of course!
2010052403.png
This and the next three images are what the wind industry refers to as "yard art". They spin, and look good, but aren't very efficient.
2010052406.png
A wind turbine for Darth Vadar, or a farm machine?
2010052423.png
A turbine like this one was tested at the National Renewable Energy Laboratory in Colorado. The turbine fell apart in just a few months.
2010052402.png
The blades aren't visible because an electric motor was spinning this display rapidly. It too is "yard art".
2010052417.png
"Kid Wind" - a project that encouraged teams of students to enter their wind turbine designs in a contest.

The judging area just prior to the start of the Kid Wind contest.
2010052408.png
The Kid Wind model turbines were tested in a home-made wind machine. The model turbine inside was being judged for the contest.

Third place winners was a team called "Dust Bunnies in the Wind". Their team won $200.
2010052414.png
Second place, and $400, went to the "Cary Colts".
2010052412.png
First place team was called "Starpoint Turbine". They walked away with $600!
2010052416.png
The "Starpoint Turbine" team, jusifiably proud!
2010052410.png
All of the teams. Everyone was a winner, even without a cash award. The kids clearly had fun!
2010052405.png
Now .. if they'd just had something like THIS on their models!
2010052422.png
Teachers struggle to get the students together for a photo. (Does "herding cats" come to mind here?)
2010052421.png
They actually succeeded in getting the "cats" together for the photo!
2010052427.png
Wind turbines from all over the world. This model is from Germany.
2010052428.png
This strange looking "football" is actually a "horizontal axis" wind turbine.
2010052431.png
A few "downwind" tail-less models were on display around the exhibit floor.
2010052432.png
Long thin blades in an attempt to capture slower-speed wind. (Does this resemble a starfish to you?)
2010052430.png
A "Jackrabbit" model wind turbine.
2010052433.png
The team from Intertek, one of the Nationally Recognized Testing Labs in the USA. They test to ensure product safety.

This totally solar streetlight incorporates photovoltaic AND wind electricity!
