Wind turbines are often seen in wind farms, but there are some that are designed for houses as well. Use the buttons below to change the wind speed.
Like all wind turbines, your turbine will stop if there is too much wind and resume power generation when the wind speed is just right. In what wind speeds will your home-mounted wind turbine run?
Find the maximum wind speed, then stop the turbine to continue.
The graph below shows how much power was generated as part of your last experiment. You can continue to increase/decrease wind speed if you want to see how the graph changes.
Below the graph you can see how much power was generated overall and how that power could be used in your home. Are you surprised by how the same amount of energy translates into power for the different devices?
Once you have examined the information below, stop the wind and calculate answers to the questions at the bottom of the screen. (If you do not stop the wind, the correct answers will keep changing!)
|Device||Power Required||Wind Required|
|Phone Charger||5 W||7 mph|
|Laptop Computer||54 W||12 mph|
|Ceiling Fan||138 W||16 mph|
|Refrigerator||239 W||20 mph|
|Vacuum Cleaner||366 W||26 mph|
|Window A/C||393 W||29 mph|
|Garage Door Opener||400 W||33 mph|
|Clothes Dryer||4000 W|
|Generated Wh total in the last minutes.|
of mobile video
of air movement
of cool food
If the average wind speed from your minutes were multiplied across a whole hour, about how much power would be generated?
(60 minutes ÷ time in minutes × Wh generated)
How many hours could that power run your refrigerator?
(A refrigerator needs 239 watt-hours of power for a 24-hour day.)
Tap check to recieve feedback.
You have now seen the limits of your wind turbine and generated some power. Let's see what that power can do!
