We were given a project to design a wind turbine with an aim to generate as much power as possible (with 24W motor). In this instructables page we will show you a step by step process to build our turbine.

Step 1: Materials

Materials Needed:

-3mm sheet thermoplastic
-MDF, various sizes
-Sheet Aluminium
- 1 x Steel Block (50 mm diameter x 50 mm height)
- 1 x M8 threaded poles  (0.6 m long)
- 2 x bearings ( 6mm inner bore, 22mm outer diamter)
- 2 x M5 bolts and nuts
- 4 x M8 nuts
- Various screws
- 2 x Gears (inner bore diamter 3mm)
- 1 x Bucket (approx 30cm diameter or wider at opening)

Tools and manufacturing process:

-laser cutter (alternative to hand drawing)
-band saw
-hot air gun
-chemical adhesive
-glue and painting
<p>Hey, nice design! It's a great start, and with some imagination, it could be the basis for some pretty cool things. Yeah, like a few people below have said, there's room for improvement, but ya know what - we're still improving upon many things Mr Edison built almost a hundred years ago. <br><br>I could see this whole thing being mounted on a swivel with a tail, so it's always pointed in the right direction, maybe even a with something akin to a jet engine's casing around it to make it aerodynamic so it'll turn into the wind easier. <br><br>I used to ride BMX, and had friends into freestyle - one of the things we'd have were brake cables that would allow our handle bars to spin 360 degrees without limitation. I can't quite visualize the design any more, but using something similar for the power cables, with this being DC, even just the positive power and use the post itself as negative, might be enough to give the full motion. <br><br>Or even using it as a beacon light, maybe with an on-board battery, solar PV panel, and some LEDs, something like this could be used at the top of high buildings and towers. Or for a Cabin in the Woods Disco :D <br><br>p.s. I know this is over 3 years old, and if the comments below hadn't discouraged you, some of my ideas might have even crossed your mind. I don't even know if you'll get an email alert for this any more. But, maybe you havn't been discouraged, and maybe you will see this. and a little something for the haters: \n!m -_- m!n/</p>
Hi cignal, <br> <br>A corded drill (cheap nowadays), a dimmer switch, some clamps, a small stack of scrap lumber, and a relatively inexpensive set of metal lathe blades is a low-cost lathe replacement. A handheld hacksaw can easily replace a bandsaw, just takes more time and &quot;elbow grease&quot;. Taps and dies are a sticky point, but you could start with a threaded rod in this case. Gears are nice but in this level of power you could get away with a rubber band &quot;belt&quot;. <br> <br>Try not to be so negative, lack of tools is a challenge, not a handicap. <br> <br>Often the tools used for the effect are less important than the thinking that went into the effect itself, the constructive steps, the &quot;inside view&quot;. This project was done as a school project, with specific criteria and available tools. Many people have places like TechShop or a Hackerspace or even a local community college where these tools are available. <br> <br>So, relax, read, do what you can do now, dream what you can do later, contribute ideas and learn for WHEN you DO have a machine shop in your garage.
Yes you do... <br> <br>Reason? IT'S FUN!!! <br> <br>Snark rules!!!!
This is going to be the future of electricity for everything in the future.The time to start learning how to build one is now. Someone needs to fiqure out how to get tv without cable.
If you've got a computer, and enough bandwidth, you have virtually every bit of access to television. On my way home from Mount Laurel, NJ, I watched a few episodes of some shows I missed during the week on a Greyhound bus. Now, the connection dropped a few times, but I was on a Greyhound bus, after all. Here in the comfy confines of my own home, I can work through my morning constitution while catching up on the night's news, and taking a peek at the weather. <br> <br>I don't mean to be snide. Well, I guess I do, but all in good fun.
I get TV without cable, using a device called an &quot;antenna&quot;.
Interesting project. Well done description on how to build the small wind turbine. <br>I wonder if your turbine would be more efficient if you used square tips on the blades and had them just inside the nozzle with just the minimum clearance necessary to allow them to spin free. Next step would be to streamline the supports.
very well thoughtout.!!!!!!
Very nice
This is awesome. One question, why the parallel cuts on the blades?
is it just for bend-ability, or does this add spin?
a bit of both! from testing, our cut blades performed better than those without
I have a question. I am a huge advocate for micro power generation. It all adds up, ya know? <br>Anyway, why can't something like this be installed in forced air heating/ac systems to help offset the energy required? I know the system itself couldn't use it, but a powering station for electronic handhelds would be a great place for the energy to be put to use. <br> <br>Any answers?
Because it would not &quot;offset the energy&quot;. It would be a load on the heating/aircon system, and in order to get the same amount of airflow, you'd need to up the fan speed or size, this would take more power. At best you would break even. This is not to say that it wouldn't make sense in some situations, but it wouldn't be efficient.
Using it for the exhausted air from heating/ac systems was actually one of our market ideas. We eventually settled upon something different, but that was a contender. We unfortunately have no expertise in that particular area, but if it could be done, Then as you said it all adds up
I must be dense or I am missing something. I see no &quot;generator&quot; in this project I see just an armature with a three bladed &quot;propeller&quot; attached. <br>What am I missing? <br>uncle frogy
For the project we we're given a motor, the motor is sitting inside the perspex block. It was re-used to generate power
I must be seriously stuck on stupid today - I just don't get the point of the cone thing in front...
This turbine wasn't tested in an open air environment but in a small, restricted wind tunnel, the nozzle was to pick up the speed of the air a small portion and to try to reduce the turbulence of flow as it fitted the tunnel dimensions exactly.
Hey, that is a nice piece of economic!I It looks nice and with your permission i am going to make one.Take care and welldone!!!!!
Of course you can!
Please test it with and without the nozzle. They are normally used when there just isn't space for slightly longer blades, or other specific problems.
For our project, it was tested inside a small wind tunnel, so the nozzle was used for that reason. As you said yourself, they are used when longer blades aren't an option
Nice work man ! <br>
You should enter into the green design contest, great instructable!
Nice project, it looks great! How much power does it generate?
I like it! Nice work.
