Online Wind Turbine Challenge

This turbine made by the Zepher Crusaders has a 1:16 gear ratio and produces 20-30 volts at low wind speeds. The blades are 3D printed airfoils with shrink-wrap over them to make the shape. The base is made from PVC pipe and a board that was found on the curb.

3 to 4 blade windmill built myself. I built this myself using tape hot glue. The cardboard needed hot glue

3 to 4 blade windmill. I did the regular design for it. Everything is good

3 to 4 blade windmill I built myself

Ratpile has 3 blades that are shaped like the wings of an airplane. The central pole is supported by 2 ropes of tape. The base is wide so it can push against the wind.

The wind turbine we created is made from PVC pipes card board, tape, hot glue, and dial rods. We tried different types of blades like A very light type of wood, card board and now thin sheets of card board. We have also tried three different bases but now we finally found the one.

The project is a shorter six-winged gold and black demon. This particular individual was faster than a track hawk. Some say you can hear the hemmy winding up when it goes.

Our blades have the shape of an airplane's wing to be able to cut through the air. Ropes of tape support the central pole.

Our windmill has 3 blades made out of balsa wood. The blades have an aerofoil shape, and the central pole is braced with tape. The base is wide to be able to push against the wind

We are a middle school tech class exploring energy

Team Jogan was tasked with building a windmill. After countless designs, materials, and attempts, we had found a good design. We spent each class period working to find the best solution..

Our project is very sturdy and has a simple design. It has 6 blades and different sizes and shapes. It was an easy and good project for our first time at this.

This project created a great way to learn about the wind power energy. As partners, we had a lot of fun trying to figure out new ways to make energy faster and more efficient. Overall, we think this project was a fun learning experience.

Plywood taped to cardboard that is taped to a peg, then placed into the motor of the turbine.

It's very time consuming. Some of the parts are very fragile. Its also on the taller side, reaching up to 3 1/2 ft tall!

We made this shorter. This made it so it was level with the fan allowing us to produce more electricity. The only downside to this is we can't have huge blades to catch the wind. We solved this problem by changing the shape of our blades. to a shape that isn't huge but still catches the wind.

Plywood taped to Carboard that is taped to a Peg, then placed into the motor of the Turbine.

This project was to strategically construct a windmill that optimizes space to produce the most energy. We did this by constructing 4 blades at certain angles to catch the wind. With a strong base able to withhold the fans' power.

This was created during a training event. I think my students will have fun!

This windmill works by taking the air that hits it and using that to spin the blades. The blade is cut and put to a certain angle to catch the wind. This makes the rotor spin leading it to create energy.

Our project consists of 3 cardboard turbines which are attached to the Kid Wind generator. We then use a fan and angle our blades to get the maximum output voltage.

We were inspired by a fan. We engineered our blades like fan blades but added some of our own design into it too. We cooperated with each other.

My project is a wind blower. This creates win.

This is a prototype created through a training program to familiarize coaches with Alaska's Clean Energy Olympics program.

The team started out using a bunch of tiny blades which failed. Then the team switched to Swedish candy fish blades which worked better. The team experimented with different pitches and decided on 10 degrees.

This project was very hard to complete. It required extraordinary dedication from my team, as well as a lot of outside research on airfoil design. In the end, we finalized our design and beefed up the components to handle the excess stress.

This is a Kindwind windmill, built by the teacher for the class. I am super excited to have my students start building these and experimenting with all the aspects of the windmill! Thank you for the opportunity for my class to join this!

This is a wind turbine prototype that aims to combine proven research-based features with twists of innovation. The project used PVC blades that are airfoiled and spaced at 10 degree pitch The hub is custom-made using aluminum material. The base used PVC pipes and structured to attain optimum stability. The gearbox used a 32 to 1 compound gear ratio. Below is a video link:

The objective of the project is to design and build a wind turbine prototype that generates the most power. The turbine used PVC blinds for blades and PVC pipes for the base. The gear mechanism uses a compound gear ratio of 32 to 1, which means that as the driver gear spins, the final driven gear spins 32 times faster thereby generating more power. After a series of iterations, below is a video of the final project (copy paste to view):

For the challenge we where given a KidWind Advanced Wind Experiment Kit by our teacher. Our group of 5 started off by designing multiple different versions of blades on Whitebox Learning. In the end we settled with a 400mm blade with a Somers S102 airfoil because of the lift drag ratio.

For our wind turbine project, our group of four started on WhiteBox Learning, researching wind turbines then moving to the programs engineering section to design blades. We first tested wooden balsa wood blades, then determined our 3D printed blades to be better and installed them. We ran our final tests and took photos and videos with them.

We designed, built, and tested a wind turbine made from PLA plastic. The turbine features 3D-printed blades shaped like long triangles. The project focuses on making the design more efficient and improving energy production.

Our project idea was to create an efficient, easy-to-make turbine. We created an arc on our blade to pick up the wind like an airplane wing or prop. We want to make wind power simple and easy to access, and we believe that this design attests to that.

I made six blades out of wire. They are not flat, so that the turbine can spin easier. I wrapped tape in between the wire frames.

we have a wind terbine. This has 3 blades with fether shaped blads. This is vary light

We made this out of scrap cardboard. Tools that we used include sanders, scroll saws, handsaws, and filers. Max Megawatts is 90.6

My project is a turbine and it has 3 sides and it spins good

This wind turbine has three blades.

It's a three blade turbine with a inward bending shape on each balde.

my project has 4 blades and it is made out of cardboard with wooden sticks attached to it.

Six blade wind turbine with hand-carved tubercles on leading edges and curved polyester/paper trailing edges. Tubercles improve airflow over blade. The poly/paper reduces weight and is curved. It flexes to reduce drag.

Homemade wind turbine out of recycled materials. Wooden base and tower to provide stability. Drive shaft made of LEGO gears.

its a three blade turbine. it has 29 cm long blades

We made a kinda half circle shape with a little curve in it. and then we put a carboard piece in the middle so it could be stable not floppy. After that we pu sticks to insert the propeller in the clamp things.

Our blade's are shaped like peanuts. They are made out of cardboard and there are popsicle sticks on the back for support.

we are a middle school hoping to learn more about renewable energy.

it is a wind turbine design. we made it out of map board. we are trying to see if it is better than the turbines right now

Our project is fast, stable and can be very efficient. We are very proud of this project and we hope it can help you on your way to more sustainable energy. Thank you!

We made a wind turbine with 28 cm blades. There were 3 blades and were each shaped like a butter knife. We made them out of cardboard and glued straws on the back to put in the hub. We then stuffed them with paper so they wouldn't get squashed and rapped masking tape around the ends so it would stay in the hub. When we first tested our turbine, it couldn't spin because the blades were too long. We then made some adjustments and our final test went great!

we did the wind turbine

Middle School Engineering Class

My project is a three blades diamond design of a wind turbine.

The project was built by 2 people shane gerber and carter cetroni. the project took a while to get all the data but we came to mabey win
