what can we do with our office supplies :P
Written by Ms. Confuse on Tuesday, July 01, 2008How can you build a windmill with office supplies?Convert wind energy into mechanical energy, tap the mechanical energy thus produced to generate electricity.
Supplies:
- Chart paper for wings
- Punching machine for holes
- a spoke and pin to assemble the mechanical unit
Either but a dynamo from a market or use an old motor of a small walk man or similar appliance. The smaller the motor, higher the success chances. 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 one 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 with rotate, resulting in the motor to rotate and the reverse current should be sufficient to glow the bulb.
