Omni Directional Wind Generator




Most Wind Generators have a tail fin to change its direction to face the direction of the wind that causes the loss of some energy that is generated.

I faced this problem when i was building one so i thought why not make windmill that can reduce this loss. so I came up with this design the funnel on top of this structure took wind from all direction and forced it on the fan thus keeping it rotating in one direction.

So without further delay lets begin...

Step 1: What You Need

Building Materials :

Cardboard/Wood, Glue, small balls (for bearings), 12V Generator, Cardboard/wood tube, wires, led to show output.

Tools :

Scissors, Pliers, Soldering Gun, Geometry Set (to cut shapes)

Step 2: The Funnel

The Funnel is the top most part of this generator that helps in generating electricity by pushing the wind into the fan.

The Funnel consists of three parts :

1. The Top Funnel its shape pushes the wind downwards towards the fan.

2. The Fins don't let the air to flow around the funnel.

3. The Bottom funnel concentrates the wind into the fan.

My Advice : Make them separately and then use the top funnel as a base for the fins and the fins as as base for bottom funnel.

Step 3: The Generator

The Generator is the main component as it generates electricity. Make sure that it rotates easily.

Use two bottle cap and stick their open bases on each other to form a cylindrical shape and make a hole in center of one of them (this will be where the axle of the generator be attached)

Solder the wires to the contacts on the generator to draw electricity from it.

Step 4: The Propeller

The Propeller is of a different kind as wind needs to blown from either its top or side. I made it this way since i required cw rotation, if you require ccw rotation flip the image.

Stick the Cylinder made from the bottle caps earlier to the Propeller this will help in joining it with the generator shaft.

Step 5: The Housing

The housing is to protect the propeller from stray winds and weather it consists of 4 parts

1. The Funnel

2. The Propeller housing

3. The Generator Housing

4. The Base

Step 6: Assembly

Assembling from bottom up :

1. Base

2. The Generator with the housing

3. The Propeller with the housing

4. Connecting the propeller with the generator via the hole in the bottle cap

5. Connect the LED.

Step 7: You Are Done

You are finished building you own wind generator that will generate energy no which direction the wind is...

Just Place it in a windy place

    Question 1 year ago on Introduction

    have you made one yet or is it just a concept with renerings?

    I think it is a new invention of wind turbine which has no limitation to get wind from any directions. If you split this project into detail description including measurement etc , it would be great to explore your innovative practice and theory. Bravooo....

    There in lies my problem i dont have access to building materials and equipment i live in a campus hostel in india, anyone who want to test this design is free to do so i believe it works in any size just extrapolate the components according to your desired size.

    This is a really great idea but would you be able to actually show each step with photos rather than sketchup.

    The one i built was for a test and it got destroyed when one of neighbors kids hit it with a football
