Project Overview

Each group is required to create their own turbine from scratch, using any materials they have available. The turbines will be powered by a fan, and each group must stand the same distance from the fan and use it at the same setting to ensure consistency. Students will have the opportunity to conduct multiple trials and make redesigns to improve their turbines. It is essential to document the final weight of pennies lifted by each turbine to evaluate their performance.

Student Award

1. Engineering Award- For the best Re-design 2. Master Architect- For the best blade design 3. Innovation Award- For the most innovative design. 4. Heavy Lift Award - For the design with the most pennies lifted.

Video Showing Your Project Working

Submit a link to a video of your wind turbine spinning up and running in front of a fan or in a wind tunnel OR a video that shows the loads in your solar home working under a solar array or the sun. Be sure your video is viewable!

Research Statement

Documentation is important. This can be used to tell the origin story of the design idea by explaining why the team used certain materials and technologies. Explain why the team shaped, designed, and organized the blades the way they did. Documentation can also show design iterations and results throughout the project with the different variables and conditions the device was tested under and highlight aspects specific to the design. This can be done through a Powerpoint presentation, narrative, or design notebooks for example.

Wind General Information

Generator Division

KidWind Division: SINGLE KidWind Generator (Teams in the 4-5th grade division must participate in this division).
Open Division: Any non-KidWind, commercially produced generator OR multiple KidWind generators OR your turbine uses harvested parts (coils, rotors) from other generators.
Homebuilt Division: ALL of the major components of the generator are constructed by the students. This would mean the coils are wound by the students and other components like the stators have been constructed, 3D printed, or otherwise built by the team.

Image of the Rotor Measurement

1 image using a ruler to show the measurement from the tip of the blade to the center of the hub. This image will be used to check the Rotor Swept Area by showing the rotor dimension.

Turbine Performance

Does your turbine fit within a 4’ width, 4’ length, 4’ height wind tunnel space?

The Turbine, blades and all accessories must fit within the dimensions above which represent the size of a KidWind wind tunnel.

Wind Speed (m/s)

Need help? See common fans (on the highest setting) and corresponding wind velocities on this cheat sheet.

Rotor Swept Area (cm2)

Need help? Check out this calculation guide. The typical range for this value is 1000 cm2 - 8000 cm2. This will be publicly shared.

Resistor Value (ohms)

This value must be a whole number. Do not use decimals or spaces. Need help? Check out this guide. This will be publicly shared.

Output voltage (V)

Need help calculating voltage? Check out this guide. This will be publicly shared.

Weights Lifted

Number of washers lifted by your turbine.

Solar Home Report

Solar Division

Solar Home Title

Solar Home Narrative

Please discuss the following components in your Narrative document:

Purpose: Set the stage by briefly describing the environment and why the selected location was a good place for the solar home. Introduce the inhabitants and their wants and needs. Talk about the solar powered features and how those features address the wants and needs of the inhabitants.

Design: Tell the origin story of the design idea by explaining why the team used certain materials and technologies. How does the team think the solar home they created is inspired by real world problems? Explain why the team shaped, designed, and organized the solar home in response to its environmental factors. Describe how the needs, health, entertainment, and comfort of the inhabitants were considered.

Connection: Explain how the team considered the social and cultural connections of the inhabitants when making the solar home. Describe how the solar home is sustainable and how it has a low impact on its environment.

Solar Panel Schematic(s)

In the solar panel schematic, include each solar powered circuit's configuration (parallel/series), and a label to what the terminals connect to. Label each panel's rated voltage and current, the length, width, and area of each solar panel, and each configurations voltage/current/wattage total. This Schematic is different from the wiring diagram because it only includes the solar panel arrangement, not the rest of the circuit. For example, if the team has up to three circuits that are powered by solar, they will need to provide three solar panel schematics.

Drop files here or

Max. file size: 10 MB, Max. files: 10.

Wiring Diagram(s)

Each circuit requires a separate wiring diagram. Teams must provide a wiring diagram for no more than three circuits. Each wiring diagram must include a symbols key. The wiring diagram should have the symbols labeled for all the electrical parts of a circuit, and every emergency switch clearly labeled as such in the diagram. If using power storage, teams will label how the solar panels are charging the power storage and how the storage is powering the loads on the device. Solar Home Elementary 4th-5th Division can create a hand drawn wiring diagram. For Solar Home 6th-8th and Solar Smart Home 9th-12th a printout is required and using a wiring diagram application is optional. If the wiring diagram is complicated, there is no need to fit it into a 8.5” x 11” paper size. The team can expand their diagram onto other pages as long as the continuation is clearly labeled.

Project Overview

This wind lift was made with 4 cardboard blades decorated with glitter and secured by tape. It had to have two cups attached as one cup wasn't large enough for the 305 pennies that it could lift.

Project Overview

This windmill was redesigned twice and worked best with foam propellers. We used weight to help hold it in place. The lighter the proprellors were the better it worked.

Project Overview

Our first attempt did not work because it was too heavy and skinny. It did not lift any weight. We redesigned it to have more blades and less materials. After our redesign it lifted 100 grams.

Project Overview

We made as many blades are we could fit into the fan and still allow the air to move through. We also tried to twist the blades so they were at the perfect angle. Then we tested multiple times and we kept adding and adjusting.
