Windafred comes out on top!

Congratulations to WINDAFRED, the wind turbine that generated the highest voltage, 4.89 volts!
The competition was tougher this year with three teams making strong showings.

1. Windafred - 4.89 volts
2. Windmill Awesome - 4.44 volts
3. Double Whammy - 3.70 volts

All 6 teams were able to generate a voltage and should be proud of their work.  Check out the playlist to see the other wind turbines.  Students will be adding their own explanations of their turbines soon.

Windafred out front!

Watch "POE Wind Turbine - Windafred" on YouTube
We have 4 more turbines to test; the voltage to beat is 4.89 volts!
