In science me, R.T.,Toby, and Josh are in a group and making wind turbine. The blades are folded to catch more air.It’s in a triangle-square shape. Picture here 
The voltage is about 1.7 volts. We are thinking about making the blades smaller. We are trying to keep the same blades by making small adjustments. We hope that we can find a way speed the blades up. Our goal is making it go over 3 volts. Hope you enjoyed this post Broy
