project description
Project Description

The purpose of the given project was to work as a team to design and build a windmill that will generate electricity.

Requirements included:-Final device must fit in .5m by .5m by .8m box-Device must operate without interaction once it is started-Show approximate calculations on the efficiency of the windmill-Use readily available materials and build device from scratch-Device must be able to operate in a safe, clean, non-destructive manner

wind energy
Wind Energy

Wind power is the conversion of wind energy into useful forms of energy, such as electricity from a windmill. Using wind power as an energy source is a rapidly growing technique. In 2008, wind power produced 1.5% of worldwide electricity usage. This is double what it was in 2005.The total amount of power available from the wind is considerably more than present human power use from all other sources. However, wind power is non-dispatchable, which means that for economic use, all of the available output must be taken when it is available. Other resources must be used to match supply with demand. Because wind is not always available, it can only be used to supply a low proportion of total demand.

design process
Design Process

Original ideas:-First idea was to use cardboard for the outer shell of the generator; second idea was to use a small electrical box-Cut up 2 two-liter bottles to use as the blades of the windmill-Use 5 small circular magnets-Wrap wire around the cardboard box the same direction that the magnets were rotating

Final design:-Use plexiglass as the outer shell of the generator-Cut up 3 yogurt containers to use as the blades of the windmill-Use 4 large rectangular magnets-Wrap coated wire around the plexiglass in the opposite direction that the magnets were rotating

device description
Device Description

Base-PVC pipesWindmill-Attached cut yogurt containers to a wood stickGenerator-Attached magnets to a nail, and ran the nail through a PVC pipe; the outer shell is plexiglass. Wrapped coated wire around the outer shell of the generator.

efficiency
Efficiency

Ideally, the windmill is a great way to convert wind power to energy. However, it is not very efficient.

Some reasons why the windmill is not very efficient:

  • It has to maintain constant speed to create power.
  • It doesn’t store energy.
  • A large amount of wind is needed to produce any substantial amount of power to be converted to useful energy.

conclusion
Conclusion

Applying principles we have learned in EF152 and wind power, we have constructed what we believe to be the best possible windmill.

Our windmill:

  • was made from readily available materials
  • meets the project requirements
  • is original
