Ecybermission

This project investigates the efficiency of windmill designs to combat the rising energy consumption linked to global warming. We hypothesize that windmills with horizontal axis blades will spin faster than those with vertical axes, ultimately producing more green energy. Through controlled experiments, we compare the spin rates of various windmill designs using consistent materials and a standardized wind source. Our findings demonstrate that horizontal axis windmills generate significantly more energy, paving the way for improved sustainability in our community.

  1. Ecybermission By Payton, Anna, Nikita, and Kira

  2. Lack of green energy. Percent of windmill usage is very low. Critical in the long run; The energy consumption level will get higher and that will just contribute to global warming. Problem

  3. Our Solution • Windmills; Lower the energy consumption rate and help the environment by not depending on fossil fuels • Find an better, more efficient design of windmills; this will increase the rate of windmill use around our community.

  4. Goal of Experiment • To find out which windmill design spin the most in ten seconds. • The faster the blades spin, the more green energy is produced. • So, the windmill with the most spins produces the greatest amount of green energy.

  5. Hypothesis • We think that the design that will generate the most 'green' energy and having a faster spinning time, is the windmill with the blades on a horizontal axis.

  6. Variables • Independent Variable – We, the scientists, will change the different axes of the windmill (either horizontal or vertical). • Dependent Variable - We will record how many time the windmill makes a full spin in ten seconds.

  7. Variables Continued… • Control group- There is no control; we are comparing two different types of windmills against each other • Constants: Home, same fan on same power setting, types of each material used in design comparison (EX: Printer paper of card board)

  8. Materials • Thumbtacks • Straight plastic straws • Pieces of tape • Corks • 12 inch square piece of lightweight cardboard • 14 inch-long piece of coat hanger wire

  9. Materials Continued… • Card stock and construction paper • 4 bottles of glue • 3 pairs of scissors • 4 glue sticks • A fan (to substitute as wind)

  10. Experiment Steps • Got all of our materials onto a table. • Build our windmills. • Set timer to 10 seconds. • Turn fan on the Low setting. • Position vertical windmill in front of fan. • Turn on timer (10 seconds) • Count how many times it spins.

  11. Experiment Continued… • Record the data and do two more trials. • Position horizontal windmill in front of fan. • Reset timer to 10 seconds, and turn it on. • Count how many times it spins. • Record the data and do two more trials.

  12. Experiment Continued… Click on pictures! How to build windmills Results of the Experiment

  13. Conclusion: A windmill with a horizontal axis will spin faster generating more green energy rather than a windmill with a vertical axis.
