Project Overview
Using your knowledge of how wind energy works, your team needs to build a small turbine to produce as much power as possible! Think about the best construction techniques and the most innovative design to make it operate. Entries will be evaluated based on performance as well as creativity, quality, and demonstrated knowledge. You can check for confirmation that you submitted your project by looking at the View Projects section of the Online Wind Challenge page.
While the Online Challenges have traditionally been monthly, evaluations will now be quarterly. After the end of each cycle, we will review the projects submitted and select a few of our favorites to feature on the website.
Submissions will be judged by the KidWind team and winners will be selected on a quarterly basis. Winners receive prizes and are invited to participate in the World KidWind Challenge, a large and prestigious in-person event, hosted at a conference center in a different state every year. Projects will be grouped for evaluation based on the following time frames:
- Projects submitted by November 1st for Quarter 1
- Projects submitted by February 1st for Quarter 2
- Projects submitted by April 1st for Quarter 3
- Projects submitted by August 1st for Quarter 4.
If your team is chosen as a winner, a KidWind staff member will contact the coach. Winners selected from Quarters 1-3 (August 1st through April 1st) will be invited to a World KidWind Challenge in spring 2026.
How Do I Participate?
- Get some gear: If you need some gear to start building your turbine we would start here.
- Download the detailed rules.
- Submit your project: Fill out the fields on the online submission form. Make sure to take pictures of your project and process! We will ask you to submit a photo of your entire turbine taken straight on, featuring the blades and hub. Any other photos of blades close up, different angles, etc. can be added as well when you submit your project.
Please note: The more data you share in the project submission form, the better our judges will be able to evaluate and score your turbine. Teams that submit details in most or all of the submission form fields often score higher.
Resources
- Anemometers: One of the most important variables we use to calculate your efficiency and performance is wind speed. While we have created the Wind Speed Cheat Sheet, as you can imagine this is pretty inaccurate! To make improve the data we get consider getting an inexpensive anemometer. This will greatly improve the data you provide!
- Wind speed cheat sheet: Not sure what the wind speed of your fan is? Use this cheat sheet to find out the speeds of common household box fans.
- Performance Calculator: Use this handy tool to test your device’s performance before you submit to the Online Challenge! The electrical output capability will be the most helpful for the Wind Turbine Design Challenge.

Cookie Cutters
Project Overview
We went with leaf-shaped, paddle cardboard peices. The first two didn't work so we were really happy that this did! After testing different shapes we found this was the fastest.

67’ers
Project Overview
Our project is simple but effective. Also I saw people in my class doing a design so I modified the design a bit. They might be different sized but who cares it works.

Wind Winners
Project Overview
This project took a lot of trial and error, but in the end, we got a perfect design. Also, we had a lot of determination with our group. Lastly, we took all we had and put it into the wing, and we used lots of accuracy and precision.

The Winders
Project Overview
We took time crafting this design and making precise measure meants. We have six wings for our project and it will make it go fast. Also we were using an angle for the measurer meants.

Chelsea & Kerry
Project Overview
Our project consists of 4b big wind turbines, with small wooden sticks on the back to connect to the spinner itself. Our turbine is made out of cardboard and hot glue to get the wooden sticks on.

FAN FAVORITES
Project Overview
Our protect is a fan favorite for all. There are 3 blades in all. Each blade is an almond shape with a point on the top. The colors of it are brown, with black polka dots.

Bibble Baddies
Project Overview
Our project has 2 blades. On the back there is cardboard so it isn't flimsy. The base has lots of hot glue to reinforce it again!

Stetson Bibbles
Project Overview
hi we are the the stetson bibbles. and we love bibble and building things. we also want to win because we have never won anything before 🙁 but we would love to win and good luck to everyone! GO BIBBLES

Dream Team
Project Overview
To make this project, first, we designed our blades on paper. Then, we cut them out and glued a stick on the bottom to connect it to the wheel. Finally, we put the blades on the fan and measured the turbine voltage and resistance.
