NEW! SOLAR POWER CALCULATORHow can you build a windmill with office supplies?
February 19th, 2009
I have a hard school project, or least it seems hard. My teacher wants me to build a windmill model with nothing but office supplies. Is he crazy? I think so. Any how can anyone help me or point me in the right direction? Thanks.
Sure. But site your sources so you don't get in trouble by your teacher. I've heard that teachers have now caught on to students ability to complete assignments in a few minutes using the Internet and so they are asking you to site your sources if you are using the Internet, like you are right now, to research an assignment.
Goal:
- Convert wind energy into mechanical energy. Tap the mechanical energy produced to generate electricity.
Supplies:
- Chart paper for wings
- Punching machine for holes
- a spoke and pin to assemble the mechanical unit
For a how to demonstration watch the video below.
Convert the Mechanical Energy into Electricity
You can either buy a dynamo or use an old motor from a small walk man or similar appliance. The smaller the motor, the better. Also get a small torch bulb to showcase the electricity produced.
How to:
- Fix the axis or motor on the spoke of the windmill
- Take two electrical wires and connect (solder) the ends to the motor and the other respective ends to the torch bulb.
When there is wind (which you can produce artificially using a table fan) the windmill will rotate, resulting in the motor rotating and the reverse current should be sufficient to glow the bulb.
